  3. After all these useful messages full of information, can I also say something about my experience about the speakers now that I have been listening to them for a few days? I'm so glad to have them. ☺️ As a first impression, I found the sound image very similar to that of the Heresy. Now that I have listened more, I can hear better how much better these speakers sound. Of course a larger soundstage and a deeper and more bass. But I now also hear more air in the sound. The sound comes out of the speaker so much easier and with more detail. The low is really perfect for me now.. Would really not want any more bass then i have right now. It is tight, just right.. And the bass comes out so airy and detailed, so easy.. What a great speakers.. I'm so impressed . What I also noticed what this speaker does a lot better than the Heresy, is to continue to display all instruments separately from each other. I even think they sound better then the lascala I also own. I must be wrong because the lascala should sound better But I haven not heard them for some years now (I have stored them) , so I kind of forgot what they sounded like. But I don't remember the midrange being like this. What the Heresy does better is the placement of all instruments and vocals. With the Heresy every instrument and vocal was pin point to a location in front of me. . With the Chorus, the sound comes more from left and right and then a bit from somewhere in the middle. But damn.. What an awesome speakers they are

  5. I’d like to thank the members of the forum (@henry4841, @yamahaSHO, @wuzzzer, @billybob, @captainbeefheart, @hanksjim1, @Shakeydeal, @Crankysoldermeister, @babadono, @Rudy81, @garyrc, @Rolox, @NBPK402, @RandyH, @pbphoto, and @Kalifornian) who contributed to this thread. The suggestions tended to deal with EQ, phase, speaker placement, and room treatment. · Given the layout and furnishings of the listening room, my options for placement are rather constrained. · Certainly, the room does need some acoustic treatment. In time, that will be addressed. · I’ve verified that the polarity of the AA networks and all of the drivers , including the woofers, is correct. · I’ve stopped using the EQ capabilities of my receiver and am now operating in Pure Direct mode (which bypasses all EQ and tone controls). My goal was to “dial in” my La Scalas before adding (and EQing) my two THTLP subwoofers. For the purposes of this exercise, I configured the amp for stereo only (no subwoofer). Initially, I used only a small set of the YPAO (Yamaha Parametric room Acoustic Optimizer) capabilities of my Yamaha R-N803 receiver. I thought that all I was doing was setting the distances and levels from the speakers to the listening position. I referred to this configuration as “YPAO neutral”. When I followed up on suggestions from @wuzzzer and others, I found that the YPAO was altering the signal quite a bit: it boosted the low-mids and high frequencies, but diminished the bass substantially. · the low-end performance of the La Scala dropped precipitously below about 200Hz and was pretty much non-existent below 100 Hz · frequencies above 1 kHz were boosted by about 5 dBFS · frequencies between 200 Hz and 500 Hz were also boosted I then turned the YPAO off and re-ran the tests. Finally, I put the receiver in Pure Direct mode so that the receiver bypasses all signal processing and routes the input signal directly to the amp. The YPAO and all tone controls are completely bypassed. This graph shows the results of the tests. For clarity, I averaged the results from each of the 3 microphone positions for each test and applied 1/6 smoothing. · The red line shows the results from the first (YPAO neutral) tests · The blue line shows the results from the YPAO off tests · the green line shows the results from the Pure Direct tests There appears to be little discernible difference between the YPAO off and Pure Direct amplifier settings. Both are a significant improvement over the results when the YPAO system was enabled. With my Yamaha R-N803 receiver configured in either YPAO off or Pure Direct mode, my La Scalas perform +/- 5dB from 64Hz to 18.5 kHz. I’m pretty satisfied with that. My next challenge will be to blend my two THTLP subwoofers with the speakers. Fortunately, that may not be as hard as I feared since, according to Yamaha, in Pure Direct mode the receiver still sends 100 Hz and lower to the subwoofer output. Since it’s clear that my room presents challenges at low frequencies, I expect I’ll need to make use of the EQ available from the SPA250DSP plate amps that power each subwoofer. Thanks to all for your help.

  6. As you can see in your graphs, the EQ is negatively affecting your response. I suggest keeping the timing measurements for all your speakers, but do away with the EQ being applied. If you are concerned with a reversed driver, just run one speaker and see how it performs in the room. With only one speaker running, the only interaction will be at the crossover frequency. It happens, but is rare IMHO. that the drivers are wired wrong. That, is generally very obvious. If you want to prove to yourself that it is the room interaction with the frequencies, take several measurements at different room locations and focus in on the bass area below about 120Hz. You will likely see some locations with great bass and other results with terrible response at the same frequency but a different measurement location. Using the REW room simulator, you MAY be able to find better locations for your speakers and sitting position. Lot easier to move a mouse or track pad than the speaker and your couch. Be advised, you are entering a very deep and dark rabbit hole.....but rewarding once you understand the limitations and what you can do about them. WAF, however will be huge factor here.

  7. Looks to me like they were wired correctly to begin with and it wasn't an out of phase issue. Dumb question time; Did you load the calibration file into REW before taking the measurements?

  8. Some of what you are looking at is the effects of your room on bass. Other than doing some type of bass treatment, there is not much you can do to fix that problem. I HIGHLY encourage you to disable YPAO, although I don't have any experience with that system, after many years of working and struggling against Audyssey Pro, I got rid of it and have never looked back. If you get really motivated, and have some open space in your back yard, take one of your La Scala's outside and take a sweep outside. Not quite an anechoic chamber, but will give you an idea of just how much your room affects your performance. I live on acreage, so fairly easy for me to do without any neighbor's houses close enough to affect the results. If you want to look at the theoretical expectation, use the REW room simulation to show you how your room dimensions affect the bass of your system. This is why the listening environment is what we should all focus on to optimize performance, not speaker cables or other snake oils.

  11. I bought an investment home basically as a place for my parents to retire its on the outskirts of a small town (Ronan) about an hour north of Missoula right along the Mission mountains. I keep one of the bedrooms here for my frequent visits kind of a second home I try to come visit 5 or 6 times a year if I can. Ideally I'd like to have some acreage outside of town but my parents are older both with age related health problems and the weather can get a bit nasty around here so this location works out perfect for them being just a few miles from hospitals / clinics and stores.

  16. I’ve had my hearing tested professionally a couple of times in the last eight years, as part of a long-term study on aging, and was given a Pass both times. The test only goes to 8 kHz, though. My hearing sensitivity seems unchanged, in that I can dependably hear very low-level sounds. However, it often sounds to me like people are mumbling, and this has worsened in the last few years. In conversation, I sometimes have to ask people to repeat themselves. As a result, I usually watch TV with the subtitles turned on, and find this is especially important when hearing unusual words or names. Ironically or luckily, I’m not sure which, the last few upgrades to my stereo have increased its resolving ability, to the point where I’m now picking up on details in long-familiar songs that I’d never noticed before. Also, twelve years ago, my building had an extensive remediation, which included installing the latest in high-insulation-value windows. Not only do they keep out the heat and cold, they keep out the city noises, so that the living room’s noise floor is now much lower than it was with the previous drafty windows. Closing a window now is like watching TV and turning off the sound. It’s that dramatic, and everyone in the building was very pleased about that, since the building is right downtown. Speaking of ambient city noise, one big difference between Toronto and Victoria is the presence of highways in Toronto. They run across the North, South, East, and West, so that anywhere in the city you can hear the sound of tires, faintly in the dry, and more loudly in the rain. In Victoria, the nearest highway is North of the city, and it leads directly away from the city, not across it, so that faint or not-so-faint sound you’d hear in Toronto, depending on where you were, is not part of the local audioscape. New word. Do you like it? As a former 12-year railway employee, another sound I could almost always hear in Toronto was the sound of locomotive engines. There are several main lines, as well as a commuter train line, running across the city. The bass content of the sound helps it carry across the city, but most people never notice it, until you point it out and they listen carefully. The commuter trains are only six or twelve cars long, so their locos can pull them up to cruising speed fairly quickly, at which point they’re throttled back somewhat, becoming much quieter. For the freight locos, it’s a different story, as they may be pulling as many as 100 cars, so they have to pull at full throttle for a long time, resulting in much more noise, or sound, if you enjoy hearing unmuffled turbocharged V-12 and V-16 engines that put out 3,000-4,000 horsepower. That’s the sound that drones faintly across Toronto, but is unheard of in Victoria, or anywhere on Vancouver Island, since there’s no rail service here at all.

  18. Interesting as I just had a professional hearing evaluation with my new insurance after turning 65. I have a test chart from 30 years ago that shows I've lost some high frequencies, but the audiologist said if he were just looking at my test results instead of me, he would have predicted a mid 40 year old. So I got nothing to complain about. But I've been pretty careful with my hearing but I now regularly work on big drilling rigs that can be quite noisy. So...ROCK ON Garth!

  19. I might suggest you focus on one headache at a time. Take the subs totally out of the equation until you get the LaS dialed in. Get the La Scalas placed so they give you the best possible performance within the limitations of your room and WAF. THEN, and only THEN, go to the REW room simulator and set it up to mimic your room. Then, you will be able to play with the sub locations. That software is particularly good at helping with sub placement. With your subs at the front of the room, you are causing problems in the most difficult frequency ranges. REW will likely suggest one sub up front and one near the back....no, not necessarily in the corners (WAAF again). If done properly, you should be able to place the subs to HELP with placement limitations of the La Scalas, thereby finding an optimal solution for your listening environment. Understand that this process will take quite a bit of time, but it will be worth the effort.

  20. I agree that you should reverse the polarity just to see if the bass increases. The La Scalas of that period were supposed to be highly similar in sound to the Belle Klipsch. My Belle Klipsch (center channel) is good to about 60Hz, where there is a very small peak, then drops like a rock.

  23. Don't know the recording quality either. Two completely different rooms as well. The recording of the cf-4 came out with a lot of sibilance for me while the focal recording was smoother. Again, most likely due to a phone recording. I have always liked Focal, though. The CF-4s really do everything so well. I do wish the crossover wasn't as complicated so we could put higher quality inductors and easier to match capacitor values and there were suitable driver replacements so we fans and owners could keep these going for another 30 to 40 years and beyond. Mostly if i have any negatives, it would be 1. They're big ugly coffins. 2. They are too low and the cheesy little feet were terrible. 3. The horn is thin and cheap and I do think the tweeter is a bit too bright/forward on the CF-4, but i solved that with some very expensive Aquaplas applied to my diaphragms. Damped the metal dome and softened and smoothed the sound, but currently testing it on the CF-3s which i already found a bit more balanced than the CF-4 in terms of the horn loudness. Now just waiting eagerly for Dean to finish up my crossovers so i can put it all together! I also applied sound deadner to the horns and woofer baskets and some bracing.

  29. Thanks. They're really nice. All original and in great shape, but for one piece of missing veneer on front strip about 3/4" long. Was going to try to fix it myself, but don't have the skills or the tools, so I'll take a small hit price wise on that point. I get it. Also one small veneer piece missing along back edge of other speaker. Not really very noticeable. Otherwise they look and sound great. They are 1977s with AB crossovers. Grill cloths all excellent. Finish is a mellow oil over walnut. Hate to see them go, but new apartment simply way too small for them. Sound big and beautiful. Thanks.

  31. I couldn't find anything in the owners manual about a hard reset or anything about the error capabilities for the chips, basically whoever uses these chips has the option to go as far as they want with what the chips offer and Topping must have not used a microprocessor for any sort of error output to save on costs. You can check the voltage of the error and reset pins to see if they are low or high which will tell you something but warranty is voided if you open it up, so my advice is the same as Cranky's, send it back and get another one. There is one thing in the owners manual I found interesting is that with most amps the speaker output - negative terminal is connected together and to common ground, the PA5 says if you happen to touch the grounds at the output severe damage can happen. Basically if you swapped speakers and speaker cables and that channel is still dead after reversing them there must be a major fault and it's not going to reset itself. Call for a replacement unit or they may have you ship it out for repairs.

  33. Here in downtown Victoria, the main noise is the sirens: ambulance, Fire Department, and police. We have all three, but luckily you can go hours, or even a day, without hearing one. This is the first place where I’ve noticed pedestrians covering their ears as a vehicle with a siren screaming drives by, and now I do it too. The streets aren’t wide, and with all the new high rise buildings that have popped up in the last decade, the sirens get lots of boundary reinforcement, or reflection, whichever is more accurate, so it can get really loud at street level.

  36. I understand that when in home theater settings but he had it configured to full range speakers and no subwoofer. I should have been more specific with the question. Where he has the the receiver in full range and no subwoofer setting that doesn't mean the processing is off, it's just in a different mode. I can't think of any situation besides home theater mode where the programming would cut bass this drastically, especially when we have found that loudness controls are popular and typically at lower volumes the bass is boosted. Basically I am wondering if there is something actually defective with the receiver. If at all possible try the same test with a different amplifier.

  37. Could be wrong but, if configured for HT, you need to do direct stereo mode to LaScalas. Please refer to your users manual.

  38. A valid test would have to have zero acoustic processing enabled and use a power amplifier with a low output impedance and flat frequency response. If this is an issue of processing why on earth would it attenuate the bass this much?

  40. Yes, I have a certain level of tinnitus/ear ringing. I am a heavy equipment operator and although I wear hearing protection 100% of the time, it's my understanding that vibration is something that can't be avoided and plays a detrimental role in this regard. Add that on top of years of loud concerts etc. In my own evaluation, I feel like I hear accurately but the mild ear ringing is merely a nuisance and distraction. Before I continue on and pretend that I'm not a deaf MFer like the rest of you guys......let's forget about hearing loss for a bit and let me crank this next song. Rock on.

  42. Just redid all the PEQ settings I had, and tried something different to measure the delays. I just used the built in "acoustical delay" function in the REW measurement tool. I redid the in/output settings in the processor so the High frequency driver got the left signal, and the Low frequency driver the right. That way it calculated the delays as it would between 2 speakers. Only took me a minute or so to do, without having to change any cables. It also extremely simple to do, and I dont think you can make any mistake interpreting it as it just says "you need to apply .... ms delay". When I applied the new delays I got a totally new speaker! Damn, the voices and intelligibility improved so much!

  43. I do something similar with REW and a UMIK-1. 90-degree calibration. Use REW's generator to produce a full-range Pink-PN while using REW's RTA and the UMIK-1 to analyze the Pink-PN signal while I do about 10-15 seconds of figure-8 patterns around my listening area. After saving it down, I use REW's EQ (variable smoothing), feeding it general parameters to automatically get my SPL corrections in the right range. But then I adjust from there - usually dialing the automatic corrections back and avoiding correction gains. Basically, less is more and I'm just trying to correct some obvious room gains and very lightly apply a 'house sound.' In my case, I then export the EQ as wav files which I feed into Roon's convolution filter.

  44. Got some pretty good sounding EQ settings last night. I decided to explore the "generalized room correction" approach a bit more. I made a collection of measurements at 8 listening positions and averaged them together and then filtered at 1/12 octave. I then constructed 10 PEQs over full range to match this. I downloaded the 90 degree mic cal file for this and used the mic pointing at the ceiling. The results sound pretty good. Fixed some bass resonances I didn't even realize were there. I'd still like to soften up the mids a bit more. Overall I found that I tend to get better results (to my ears) with the PEQ's cutting rather than boosting. If I allow the PEQs to have unlimited positive gain and position the target response in the middle of the recorded data the predicted response is nearly perfectly flat, but to my ears it sounds a little better if I instead set the target response a little lower and restrict the PEQ gains to no more than +3dB (or even 0dB). I believe this forces the algorithm to do the best it can with cuts only.

  45. I'd recommend going to this source to download a guide: https://www.dropbox.com/s/zdhq72a1puyyxpr/REW 101 HTS Current Version.pdf?dl=0 Also, there is a legacy REW support guide page: http://www.hometheatershack.com/forums/rew-forum/11707-room-eq-wizard-rew-information-index-links-guides-technical-articles-please-read.html Not really. It's actually easier than multichannel--all you have to do is match the performance of essentially identical loudspeakers in symmetrical positions in the room. If you add a sub, it gets a little more complicated, if you add a center, it gets a lot more complicated, and surrounds are incrementally more complicated, etc. Yes. Always. Sometimes you can add the subwoofer(s), but only if it is very close to the stereo pair of loudspeakers. For all measurements except subwoofers, always place the microphone 1 metre (yard) in front of the loudspeaker, centered on the midrange/tweeter interface, looking up at 30-45 degrees. It's exactly what is appears to be. You want the leading wavefronts from the bass, midrange and tweeter to arrive at the same time--an impulse. There are a few ways to see the time alignment of the various drivers/horns using REW, and there are a couple of ways to facilitate time alignment (physical alignment and time delay using a DSP crossover). Generally, the answer is the first one, but there is some effect of flattening the frequency response that also flattens phase. The two subjects are generally treated separately, however. I usually correct the frequency response first, then time alignment, then fine tune the frequency response again, especially in terms of controlling the timbre of the loudspeaker if you've got timbre matching issues. Yes, you can get that with a DSP crossover and bi-amping or tri-amping. If you're really serious, you can get special types of DSP crossovers that have something called "FIR filters" or "finite impulse response". These can correct phase and amplitude at the same time. But they're usually more expensive and they need a little more depth of understanding to use effectively. Generally, you can get there without using FIR filtering, but if you've got a nasty problem, you can use it to get out of issues. Chris

  46. By the way, REW uses the smoothness settings for the measurement frequency response plot (that you set under the "Graph" menu) to determine the optimized PEQs. I recommend using "Psychoacoustic" smoothing before running the EQ filter optimizer, so that you're not trying to create a lot of high-Q (i.e.,very narrow) filters that are probably trying to correct for room modes. Once you select "Match Response to Target", the PEQ filters are created and optimized before your eyes, and you can see them numbered as they are created, and even deleted as the optimizer continues to skinny down the number and strength of the individual PEQs. You can also use the "Modal Analysis" and "Resonances" menu bars in the right hand side of the EQ window to plug in your room's dimensions and calculate likely room resonances and cancellation frequencies based on those room dimension inputs. I find that somewhat useful in deciding if midrange and midbass PEQs that are generated that also look fairly narrow and steep--to decide if they are in fact trying to boost or cut room resonance frequencies. I find this is a useful feature to have for all loudspeaker PEQ optimizations. Chris

  47. It sounds like you are using this on your "new-fangled" horn with drivers in the K-402. So I guess it is partly a philosophical question. When you do this with the traditional version of a Klipsch jubilee, there going to be peaks & dips at the lower frequencies due to a smallish mouth on the bass bin. I have always bee liberal about flattening the peaks but conservative about boosting the dips too much, especially at lower frequencies. With regards to the measures, if I place the mic at the mouth of the bass bin (or even slightly inside) the measures are quite similar to those that Roy Delgado has provided (certainly at the lower frequencies). However, when I pull the mic back and away from the bin, then I start to see all sorts of "room effects". One can then get into this back and forth about "correcting" the speaker itself vs "correcting" the speaker-in-that-room. Some are opposed to correcting for the room interactions and others are not. Those opposed frequently have some soft-headed thinking on this issue. When I read Toole's book he seems a bit more lenient and encourages a degree of correction. When I am not worrying about this stuff, I am actually enjoying the sound. Will it never end?
