  1. dudes on youtube: we want speaker comparisons. us: ok, we'll do a review and tell you all about it dudes: no not like that. we want to know what you're playing. us: ok, we'll give you a big list of everything we're playing so you can try for yourself. dudes: no not like that. we want to know when you're playing which speaker. us: ok, we'll give you a list of what's playing when. dudes: no not like that. We want to actually hear them. us: wellllll.... you're largely hearing what the room sounds like, on a cheap cell phone speaker, and we're not big fans of enabling that because it's somewhat intellectually dishonest and may inadvertently sway your decision to something that isn't fully truthful. But ok we'll play some of the music so it's not awkward. dudes: no not like that. we want to hear the differences and know exactly what speaker is playing when you switch them. us: ok but there are licensing issues with big bands, so we're going to get some super cool local Indianapolis bands to give us a licensing agreement, then we will fully play this music and document exactly what speaker is playing and you can see what band is playing and maybe you might find something new and the bands will get some much need exposure and we don't get sued or have our channel dropped and everybody is happy, cool? dudes: no not like that.

  3. Also thrilled to report that almost an entire can of DeOxit spray was used and the input selector knob finally was moving and moving well and alas - both channels work and sound amazing! a couple of the switches were quite dirty too - one of the speaker selector switches spring wasn't clicking, a little cleaning to do and a light to replace at some point but for now just enjoying it... thanks everyone!

  4. Absolutely. I've sold a ton of speakers based on the youtube videos in general and yes plenty of people including myself use YouTube to go car shopping. Actually YouTube is golden for more expensive vehicles with unique and complicated features such as my Raptor. The idea that I'd buy a $70,000 truck based on a few cheap sales pitch lines from the local sales idiot (who may have never even seen one before) rather than scour YouTube for more in-depth demos and reviews is far-fetched.

  5. For me it's fairly simple. If someone is going to record video to share to an audience of some kind, might as well use a decent video device rather than a crappy one, to go for a clear image. As well, if you are going to record audio gear playing music, might as well have a good microphone too. It doesn't have to be a binaural head, but could be of quality. Then there is no reason for a conversation, audio and video are both addressed in the proper way. For those who don't think music can be recorded well on youtube, I'll offer this vid up for perusal.

  6. It was just my way of saying that it can never be an apples-to-apples comparison. Sealed boxes have an excursion disadvantage near the tuning frequency of an "equivalent" vented box, but that can be largely mitigated by the fact that you can double the cone area in the same sized box. There is more than one way to skin a cat. There is more than one way to optimize a design. Except that rogue excursions below f3 cause modulation distortion, and can easily bottom-out a driver in a vented box unless a highpass filter is used. Such a highpass filter further degrades the impulse response. Again, if one takes advantage of the potential doubling of cone area in the same volume, maximum SPL follows. While it may not be important in a home stereo context, it can be very important in sound reinforcement context. (I come from a sound reinforcement background.) A filter is a filter is a filter. Doesn't matter whether it's resistors, inductors, and capacitors, or a driver in an enclosure. It's all the same. Neville Thiele and Richard Small figured that all out something like fifty years ago. Not possible. A 4th-order impulse response cannot be as well-behaved as a 2nd-order impulse response. The difference is quite audible. Context again. If you want the smallest volume possible, then sealed is the way to go. If you want the best transient response possible, then sealed is the way to go. If you want the simplest enclosure design possible, then sealed is the way to go. If you want the most bang per driver (or per dollar), then vented is the way to go.

  8. I look at it this way.... (and obviously I wasn't there in the beginning) But...."in the beginning" PWK designed the Khorn with how many years of experience building horns? My guess is zero. Made something pretty cool and it developed into a nice company. 50 years later he (and Roy) set out to essentially re-create the Khorn as per his original thoughts... a 2-way speaker. However, THIS time he's been noodling around with speakers & horns for several years.... and has some tricks he's learned along the way up his sleeve. Having heard both, it's no surprise to me that the Jubilee might (does) outperform the Khorn.

  10. It boggles my mind that they can't be tracked. If someone can figure out a way not to be tracked, you'd think that someone could figure out a way to track them. I'm speaking theoretically as I know zero about how they hide their identity.

  12. I made a recording of the '89 LaScalas I had, powered by my Moondog 2A3 amps. While I shot video of them on my phone, I recorded through an audio interface 24 bit/ 96K sampling. I tried a couple of different mic techniques, with different microphones. Trying to remember as it was over 10 years ago. I tried a coincident pair and and ORTF pair IIRC. I messed around until I got one that sounded the same played back as when I listened while recording. Once I had that, I should have tried some different speakers without changing the recording setup... but I never did. I would have been comparing to my Heresy IIs and JBL 4311s. Might have been interesting.

  13. Rigma... He and his wife are both on here. When he posted info about his build process, the Chief commented, asking if he had seen him hanging around the Klipsch wood shop. They were exceptional, still are. I believe he's bought two pair from Klipsch since he built them. He has a 1502 sub as well. I don't know for sure but it was probably more a proof of concept for him. He was certainly impressed enough to buy the real things.

  14. Returning to the issues of bass extension and cone excursion from the other thread, I prepared a few graphics. I took the same BMS 18n862 driver in the same 171 liter vented box, resulting in a "QB3" (quasi-Butterworth 3rd-order) alignment. This alignment is very close to a 4th-order Butterworth alignment, with slightly better transient response at the expense of some loss of low-frequency extension. Suppose that we want to equalize that 31.5 Hz response to be flat to 30 Hz. That's not much EQ, but I wanted to put everything on equal footing. The figures marked "Butterworth4" show this situation. The black trace in the left half is the natural response of the system, the blue trace is the desired 30 Hz response, and the red trace is the EQ required to get it there. The trace in the right half is the impulse (transient) response of this system. But, as we discussed, a vented box really needs a highpass filter to prevent overexcursion below the cutoff frequency. Most people just introduce some arbitrary highpass filter and hope for the best. Instead, I will mathematically change the 4th-order Butterworth response into a 5th-order Butterworth response. This accomplishes two things: it adds a 1st-order highpass filter to prevent overexcursion, and it maintains the desired 30 Hz cutoff frequency. This situation is shown in the figures marked "Butterworth5". Note that the EQ is cutting rather than boosting at very low frequencies. Note also that the transient response has degraded. Now let's put that same 18n862 driver into a 96 liter closed box. This results in an optimal Qtc of 0.7071. And then let's EQ it for 2nd-order Butterworth response with cutoff frequency of 30 Hz, exactly as in the vented cases above. The figures marked "Butterworth2" show the necessary EQ to accomplish this, and the resulting transient response. The EQ adds about 9 dB of constant boost at low frequencies (undesirable), but the transient response is outstanding. Finally, let's do the same thing to the 2nd-order closed box response that we did to the 4th-order vented box response -- add a highpass filter. The figures marked "Butterworth3" show that about 7 dB peak boost near 30 Hz does the job, while the EQ again cuts rather than boosts at low frequencies, to avoid overexcursion. And the transient response, while not as good as in Butterworth2, is still better than the original Butterworth4 of the vented box without the highpass filter, and far better than the Butterworth5 with the highpass filter. Still concerned about overexcursion? Use two 18n862 drivers in a box that is only slightly larger than the vented box, and you cut excursion in half while picking-up 6 dB sensitivity, so that 7 dB peak boost is not so painful any more. The downside is the cost of two drivers.

  15. Lawd have mercy! My buddy's on a brush trimmin in the ceiling listenin to some old Joe Walsh on Oppo. Where's my brush you ask? Still calling my name. Rolled out early and decided today would be the day the long front planter was gonna happen. 6 bags of "enriched" garden soil & 3 flats of flowers went down. Yes, I'm now almost domesticated. Guess I'll go get a brush movin.

  18. Thank you for sharing. Yes, the video sounds great. The man in the video is good concerning audio. Many say YouTube videos don’t have the ability to sound good, but I’ve heard many that do. I listen with good headphones and it’s almost like I’m there. I enjoy the room acoustics too. I know what a good audio system sounds like and a quality system when I hear one. I like the music in the video you shared too. I’m buying the CD of it. I discover and buy a lot of good music by watching YouTube videos of those who play music on their quality audio systems. Another good audio speaker YouTube series is Kenrick Sound. They post regular videos of speakers and you really get a good sense of how they sound.

  19. This is from page 420 of Toole's first edition (Sound Reproduction...): This is why. I hear it clearly in my setup, so do my "control listeners" that I invite to do A-B comparisons, in blind fashion without telling them what changed or what they're listening for. This isn't a "fixed-installation PA loudspeaker" thread. It's a build and test thread for the home hi-fi loudspeaker--the K-402-MEH. The requirements are a lot different. I chose those requirements for home hi-fi application for this thread. If you have different requirements, I welcome reading your similar thread on your own MEH builds. We also now have another thread on other MEHs (the "nearly full-range MEH" thread) that you can reuse for your projects, if you so choose. I'd like to keep this one focused on the K-402-MEHs if possible. I recommend it highly. I think there are others that have built their own K-402-MEHs that can attest to the sound quality of their bass reproduction. Chris

  20. This is a typical diyAudio common requirement. In this thread, the implied requirement is sound quality, and being able to get the loudspeakers into the living space without sacrificing Jubilee-levels of sound quality. You can't get that kind of sound quality (including freedom from impulse and phase/group delay distortion, as well as an arbitrary reduction in realizable bass extension) using bass reflex...in my experience. I'm always amazed at those that can't hear what PWK heard, and even advised against mixing closed-box/fully horn loaded bass vs. bass reflex for his own loudspeaker models...and this hasn't changed since 1976 when he wrote the following words: https://community.klipsch.com/applications/core/interface/file/attachment.php?id=80871 I hear the difference. I'm not afraid to challenge the commonly held notion that "bass reflex is better". It isn't. It's a design compromise that I find that I don't need to make in the loudspeakers in my setup. YMMV. Having said that, of the bass reflex designs that I've heard, the Cornwall is probably the best at hiding the audible effects of that tradeoff using bass reflex. But the tradeoff PWK used is that he used a bigger box than others typically use to do it--and a lower port frequency--in order to limit the rise in phase growth and simultaneously, group delay. Modulation distortion effects of the woofer moving more or less unconstrained in its baffle vs. an acoustic suspension (sealed) design are still audible, as PWK noted. More on that subject here: https://community.klipsch.com/applications/core/interface/file/attachment.php?id=82430 and here (a good article discussing jitter, and its relevance to modulation distortion in loudspeakers--and its audibility): https://www.stereophile.com/reference/1104red/ Chris

  23. What I need to do is quit trying to appease people who are trying to audition nearly 4' wide 250 pound speakers on a YouTube video on their computer or phone. I find it silly myself. It keeps snowballing. Even with a perfect setup the only thing you will be able to manage to pull off is showing the basic frequency response and not much else, and even that is largely being affected by the room and speaker placement. At this point I'm pulling the plug on such things for nicer speakers. We just got some Perlisten S7t's in, just not even going there. If you want to know the frequency response without the room being a factor then look at a chart. Jason has ordered a nicer microphone setup but at this point I've lost interest and won't be doing it on more expensive speakers. Thanks to everybody for overanalyzing it. Just non-stop trying to defend what was recorded every time one of these gets published. Gets kinda old. If you guys can do better, well, do it.

  28. I'm sure that this is information that people need to understand the difference between these two loudspeakers. However, I'm also sure that it isn't always welcome by all that have held the Khorn out to be the loudspeaker that started PWK's company in ~1946--and is still going 75 years later. I do believe it's worthwhile to point out that the Klipsch Jubilee that they are listening to is also PWK's design (with Roy apparently doing the "elbow grease" duty with PWK's recommendations on which way to go). So the Jubilee is reportedly PWK's last loudspeaker design, and I think that should be remembered in this context. When the Jubilee bass bin was completed, PWK was in his mid-90s. Roy was able to assist Mr. Klipsch in realizing the last instance of his corner horn design with "all the bells and whistles" learned after more than 50 years of design knowledge in how to improve it poured into it. That's what these two guys are listening to. Chris

  33. More excellent replies! A special thanks to @AndreG - that Crites Speakers website has everything, exactly what I need! Regarding the external finish: I dug out the original paperwork and attached PDFs of two scanned pages. If I read the papers right, both @willand and @Bacek are correct - the finish is definitely Oak Lacquer and linseed oil is definitely a Bad Idea. But....although the finish still has some gloss it also looks and feels a bit "dry". Googling for tips on caring for fine lacquered wood finishes, all of the advice is negative: don't use any products containing ammonia, bleach, alcohols or anything acidic.

  34. What this is basically saying is that the "back chamber phase inverter"--i.e., bass reflex or tapped horn--continuously moves its effective acoustic center away from the listener as the frequency decreases (or lobing increases the effective distance between the direct radiating woofer and/or port and the listener) below a certain break-point frequency where the phase inverter, i.e., port resonance, kicks in. This seems to be the common denominator of these designs, and unfortunately, this isn't a desirable characteristic--in my experience...and the source that Toole cited in his book (referenced here in the K-402-MEH thread).

  36. I'm in a 12' x 20' x 8' but I am in a little bit of an unconventional situation as I want to listen to music all day while working from home. but my best spot for internet is not the best spot in the room for listening. Luckily, I only have 3x LaScala, but I can stack 3x sideways to make one line array. I kind of like the wall of sound listening concept. I thought I would ask for ideas before attempting any heavy lifting, but so far from the examples, my brain is thinking of some good scenarios, although in my situation there is a chance all the speakers will be behind me.

  37. Emile, I have heard them and thanks to Chris's Xilica settings, I can flick easily between the 2way 402 and the 2way 510. The 510s are no joke, but the 402s need to be heard to really understand what they do. It is just that the 402s are the punchline!!!

  39. I don't believe "the story" of any of the logbooks has been told. The first Klipschorn logbook (including Rebels and turntables!) has PWK's hand all over it. Other early logbooks have his hand occasionally. Most early entries were done by his first few employees, such as Lloyd McClellan, Portus Gilley, and John Jones. A few others may be sprinkled in there. This Cornwall logbook is NOT in PWK's hand. Up until the early 80's handwritten logbooks documented serial numbers with components used and where they were shipped. Entry was by many shipping personnel over the years. The advent of computers made physical logbooks extinct, with subsequent records lost. KHMA has most of the logbooks, but not all. Several of the Klipschorn books (1964 - 1975) disappeared decades ago.
