Early this afternoon I hooked up an older BD player to my AVR via optical to be used to play my CD collection ( which I haven't opened up in years ). As far as music, I’ve been either streaming or iTunes listening. I almost forgot how it is to pop in a CD, sit in that “sweet spot”, and just enjoy the tunes ( with a drink in hand of course lol ). Very relaxing...and the SQ is obviously better lol. I’m almost looking into vinyl....😉

I still thinkin' 'bout Peach Moonshine.....MMmmmmmmm......

I have to admit to looking in on it. I am still gaining appreciation for these LS. I was "deprived" of working thru a half dozen set of speakers to get to where I am. I can't say I wouldn't like to have a bass to 20hz.. But that horn would rather imposing. I been following the super MWM thread, too

Yea really quiet around here. Everyone is at the Heresy3 thread!

It's getting a little scary, it's been over 24 hours since a post. Couldn't let it go 48.

As I mentioned in the Subjective Auditory Effects of Quasi-Linear Phase Loudspeakers thread, it sounds more "solid", but not necessarily better. I attribute that to having more overlap on the 4592 ND midrange/tweeter diaphragm output, however, I can't see any differences in the spectrogram plot, i.e., time vs. frequency vs. SPL, in terms of ringing or interference since the frequencies are so high and the phase relationships so hard to see. I will do an A-B listening test soon of the two phase/PEQ configurations, perhaps today. I'm not sure that I'll be able to say how the sound differs, but I will likely be able to say which one I like more. I'll be listening for detail on the cymbal transients, etc. among other HF reproduction artifacts. Chris

Order some more. That will help you remember what you did with it. 😄

No, not really. The MEH design relies on the phase lag of the electrical crossover filters to time align the drivers. I just independently confirmed that fact today. Strangely, no it really wouldn't add the needed time delay (unless they are 4" long and narrow ports) but the added air compliance of spacing the woofers farther away would compromise the HF performance of the woofers both in amplitude and phase. Actually, adding electrical crossover filter delay is not an issue. In fact it says that the electrical crossover network can work to your advantage in the design, and having the crossover simplifies the equalization of the loudspeaker. The phase growth of MEHs, like these two designs exhibit, has about half the total phase growth as is found in even the most expensive direct radiator designs--which usually have a minimum of 720 degrees of phase growth from 20 kHz down to their bass -3 dB point. These two designs have significantly less phase growth. This is something that not a lot of people realize: the performance of MEHs from an amplitude, phase, group delay, time alignment, power response (consistent coverage) and modulation/compression distortion standpoint is probably the best performance that one can get. (YMMV.) Chris

Looks nice and works , I would put it as VGC, some very minor blems on the cabinet and I mean minor, also has a few bulbs out. But does work. As the ad says its in Chicago 60631, can demo. Rather not ship but its dooable and i can take PP. Sold as is, built between 78/79

Upgraded my system recently and will be putting these speakers for sale. Single RB-81 II, in black. One speaker only. Single KV-3, in medium oak. They're sitting in a closet, but can take them out and post pictures of the Rb-81 and more of the KV-3, if anyone is interested. Both speakers were used as my center channel until I found a KLF-C7. Not sure what the price should be, but thinking around $120 for the single RB-81 II and $80 for the KV-3. Is that fair pricing? I don't have boxes, but can drop them off at FedEx. Shipping from 87110.

You are a lucky man.....

The drivers on the Klipschorn are not weak point of that system. So if everything is working, I would not bother

I'm using the Cambridge CXA60 with some Radian Coaxials which have the same sensitivity as the Heresy III. Trust me, unless you live in a barn, it'll get plenty loud enough. I've owned a lot of integrated amps over the years, the CXA60 makes my top three.

Something is wrong there. Heresy IIs aren't normally referred to as having weak treble response. To the contrary I've had to convince people that saw mine and belittled me on my decision to buy them because they were harsh and did not sound real. After I'd heard their JBL bookshelf muffled mess for sound with a high dollar receiver in the proper zip code part of town. Had a big 125/wpc Yamaha with the treble knocked back a bit and the variable loudness dialed back too. I heard realistic sound reproduction, they did too, and reluctantly agreed with me after half a record at different volume levels. Knee-jerk thought from me is the tweeters have a loose connection or are shot. The age probably necessitate crossover refreshing irregardless of the above. Thinking if you do the xover first maybe the tweeters could end up being fine after all.

See the attached PDF. I tried to look at several of their review measurements to see if there was a characteristic trend - sort of is but also relatively inconclusive. See if the plot in this review helps any. Also, there's this thread and the followup (which ended unended). forte_III-hifi_news_review.pdf

I agree. I use 2 subwoofers with my K-Horns, even though I get adequate bass from just the Horns themselves.

If you have an spl meter and test tones you can check. Put the front at 0 and the rear at 0. Play a test tone and record the spl at the listening position. Do the same thing again but this time with the rear at 180. If the reading is higher with the rear sub at 180 than 0 leave it there. If it's higher with both at 0 then leave it that way.

For Absent Friends Sunday at six when they close both the gates A widowed pair, Still sitting there, Wonder if they're late for church And it's cold, so they fasten their coats And cross the grass, they're always last. Passing by the padlocked swings, The roundabout still turning, Ahead they see a small girl On her way home with a pram. Inside the archway, The priest greets them with a courteous nod. He's close to God. Looking back at days of four instead of two. Years seem so few (four instead of two). Heads bent in prayer For friends not there. Leaving twopence on the plate, They hurry down the path and through the gate And wait to board the bus That ambles down the street

The SH-50 woofers don't roll off on the high end smoothly. They have a response peak up around 1.5 kHz and a much smaller one at 2.6 kHz that interfere with the smooth roll-off, and which affect the combined response of the woofers, midranges, and tweeter. If the woofer response is rolled off at 6 dB/octave using the electrical filter, it puts those 1.6 and 2.6 kHz response peaks much further down in SPL, thus simplifying the EQing of the addition of all three channels--which are all using notch filters in the crossover network individually to flatten the frequency response. Without the low pass filter on the woofer channel, all three channels would be significantly contributing to the ~700-3000 Hz band--which is actually too complicated to EQ easily. The woofer channel low pass roll off filter also pushes the time delay of the woofers back into time alignment with the midranges. Two for one. One thing that few people understand: there is no reason not to let the drivers in an MEH significantly overlap their frequency response bands, since their outputs sum within the aperture of the horn and their polars are also enforced by the horn to be seamlessly summed in SPL and directivity, i.e., there is no lobing. This makes channel overlap a good thing--especially if the natural HF roll-off of the woofers and midranges is sort of abrupt (like the K-55/K-400 midrange response is in a Khorn or La Scala, which for many year models also don't have a low pass electrical filter). This is probably the first major revelation of the MEH design that became apparent with the initial setup of the K-402-MEH crossover settings. The rules that work for separate-horn or direct radiator flat baffle loudspeakers don't apply to MEHs in this regard. Chris

Signal going to a driver which is bandwidth-limited at its upper end (woofer, squawker) goes through an inductor (coil) which causes a delay in the current waveform of 45 degrees. If that waveform took 1 second to make a complete cycle, after the inductor it would start 1/8 second late, then end also 1/8 second late.

Well if you insist I can post some pictures later this week ;D Of course by then they will have MAHL tweeters in them.

I have heard it said before (probably on here), and I can attest to it as well, the only regrets come from NOT doing something. Physical appearance aside, I think I prefer the Tangent 5000. Front firing passive and the tweeter is higher so the sound fills the room when milling about. Worse case scenario, you like them so much you sell the Fortes and put the extra dough towards a pair of LaScalas! The Klipsch ladder is for climbing, lol!

...he’s short-stroking it with the camera (!) in anticipation of the profit...

They were, but I had to downsize. Yes, the guy who built them did a fabulous job. I was sad when they were gone, but not too sad, since I got a matching center channel now.

=== I too have a Dennis Inspire and have always found him to be extremely nice and most pleasant to speak with. I can’t comment on his business practice on returns, but I digress. Since you have had the amps for just one day would it not be prudent to give them a week or three and see how you feel then? Or try them for a week and roll in different tubes. His sound can be described as “soft” maybe “mellow” which is how many of Cary amps have been described. You might give the Russian military 6n3c-e a try. Probably the best tube I’ve tried with mine with a more “direct” sound. And - were you familiar with SEP sound prior to the purchase? Possibly that genres is just not your cup of tea — good luck.

OK @ClaudeJ1 ... you made me spend money again Haha ... only $42 Got the 100Wx2 KnobSound on order WITH the transformer (easier than buying them separate). Anyone else interested, here is the link https://www.ebay.com/itm/Nobsound-Mini-Digital-Power-Amplifier-HiFi-Stereo-Amp-100W-2-with-Power-Supply/282997128167?hash=item41e3f17be7:g:UWwAAOSwFSRbkX3U

It actually expired on August 12 2014 due to non-payment of fees (back dated to 6/25/2014). The Google patents date at the top of the patent page is actually in error (in terms of interpreting what it's saying) and also referring to the 20 years expiration date based on application date and time: 28 April 1999--which occurs in about 6 weeks (...a moot point). Chris

None of which sound like Oris horns with tang bands.. Totally different experience.

I used to think that and in the past, accepted that dogma as true. Due to my experience and willingness to experiment I have come to the conclusion that "timbre matching" is an old wives' tale. I know what voices are supposed to sound like. The above pictured Usher Center (now replaced by the RC-64 III in the rotation) absolutely makes the RP-600M's sound better. A clear, quality center does NOT make the L/R sound worse. The key is a getting a high quality center, not simply a "matched" center. The L/R plays mostly musical content, not dialog. There is no case in modern recordings where the L/R plays the same content as the center. Ninety percent of movies/TV is dialog and 90% of dialog comes out of the center. Try it, you'll like it!

Why in the world would you suggest that timbre' matching doesn't matter it most certainly does. A mismatched center will ruin the whole front stage. You photo above is a great example of what NOT to do.

It only has to please 2 people, if you worry about what anyone else thinks your wasting your time.

Bump for an oldie.. Re-linked all the old relevant pics that got messed up with photobucket.

You too! Man this snow is getting old!

Know what you mean John. 102" of rain drowned my St. Augustine. Just resodded the front yard.....back looks okay. Thanks for reminding me I need to throw out some preemergent weed killer.

I’m catering to a club of 250 to 500 not a necessarily festival stage of 5000 people. Plus I run on my Vinyl only nights tube amps on the La Scala. Trying to go for something more intimate. Kind going more for those Hi-Fi clubs that been pop up finally in the States but in Japan and else in the world for a while now, like places like New York City been catching now. https://www.stereophile.com/content/dj-club-sound-systems-brooklyn

Over the years I have gone to a place called Gentec International on the outskirts of Toronto for Klipsch replacement parts when I have blown a woofer or a tweeter. A few months ago I got the idea to replace the K-79 in my Cornwall II's (keepers - for now...) with the K-107-Ti (a tractrix titanium unit)! They dropped in with a little filing of the cabinet cut-out and one side of the anti-resonance ribs on the tweeter. After I intalled them I enquired about the availability of the K510 and K-69, knowing full well that failing anything short of a double amputation I WOULD be converting an earlier pair of Cornwall 1's I had into Cornscala's. I was told the K510's were available but not the drivers. They even had two in stock! A twenty minute drive from work saved me shipping and started the wheels turning. Over the holidays I upgraded the crossovers in my CWII's with the Crites units, which had an impact you needed to hear to believe. I did the A/B test with one upgraded speaker, but nothing gelled until both were done. It is without a doubt something to put on the "to do" list if you have speakers you ALREADY like that are dated. Now here is the clincher... I emailed Bob (Mr. Crites) thanking him for his help. I told him after much searching NOTHING came close to the performance and value of his Faital Pro HF200 drivers (even after CDN$ exchange, shipping and customs!) and asked about a crossover to go with said drivers in this project. I also asked about the benefits of one crossover frequency over another. This was his response: "I have not tested the HF200 on the K-510 but would expect it to perform very good on that horn. If the K-510 horns were actually available in good quantity, pretty sure I would be using them in my 2-way Cornscala. Anyway, the same crossover I build for the Style D Cornscala should work fine on your speakers. As far as crossover frequency, I think 500 is best. I determined that acoustically measuring the frequency response when I did the Style D. That is so similar to what you are doing that I would be very surprised if 500hz were not the best on yours also. You have to realize how really close to my Style D you are building. I use the Faital HF140 on the Tractrix LT142 horn. The HF200 IS the HF140, just with an adapter to make it a 2 inch instead of 1.4 inch." How is that for encouragement? The crossover used in Mr. Crites' Cornscala D is the CS500. He is currently selling them for US$250.00. This is where I thank ALL of the forum members who have shared their experiences, and in so doing, make it possible for myself and others to take the enjoyment of this fine hobby to previously unknown heights. Gentlemen, my sincere thanks!
