I think a subwoofer. Look hard at the RW-series, esp. the 12.

Pretty darned good! Where do you live? I might be willing to demo mine.

The autoformer in a Type AA reduces the squawker output 3 dB. Without it your K-horns would sound pretty bad. If you took it out the capacitor for the squawker would have to change. It would have to be twice as big, I believe. With the proper changes, an L-pad could be used.

Nothing succeeds like excess!

The data I have is still at work. I believe the magic number is 3 cu. ft. I was able to get that volume in a corner configuration that was tall and had a footprint just smaller than the Heresy would have. You'll have to download/buy a box design program. It will give you the volume and you will have to play with the dimensions to get what you want.

Yep! One thing at a time. I like the sound of Hovland Musicaps. First move the low tweeter to the other cabinet to confirm it is not the tweeter. Then replace the caps with Hovlands or your favorite, new. If that fixes the problem, consider other upgrades. If it doesn't look for other problems using the attached Schematic as a guide. I have a modification for the Type E that drops the squawker and tweeter closer to the output of the woofer. I had to do it to get a tonal match for my La Scalas.

Since the schematic I posted was published by Klipsch, I'd make my crossovers match it. If you want to confirm the schematic is correct, call Klipsch. If you find it in error, please post the information on the Forum.

Timebomb.

Path length is the horizontal distance between the voice coils of 2 drivers, or the distance the sound must travel before it reaches the "front" of the speaker. Both of your crossover networks should be identical in all respects.

Not. If you build a new box for your Heresies, build a ported box. You can acheive Cornwall performance.

If you have extra components, build a center from your components and 2 Heresy woofers! Can't go wrong with that. I estimate it could acheive 98-99 dB/w/m!

In the $600 price range the yet to be issued Klipsch RW-12 seems to be able to take all comers, esp the Velodyne CT-120. I'd give it a listen before buying. That said, there is no such thing as too much subwoofer (just turned up too loud). The subs (2) I use each occupy about the same volume as a small chest freezer; there's no success like excess! I recently discovered the system is 3.8 dB below 1000 Hz at 16 Hz! I'd have never know had the meter not moved.

The tweeter rolls in around 4500 to 4700 Hz. If you have a Type AA, the K-55-X (newest) should be a great replacement for your K-55-V. After seeing the plot, I recalled Trey showing me somthing at Indy that I didn't fully understand at the time. Now it makes sense.

You can get more out of Heresy components buy building a ported, tower cabinet. There is some question of the La Scala bass horn being able to reach the 700 Hz cut-off frequency of the Heresy squawker horn. If you make the La Scala horn smaller, you will make it shorter, raising its cut-off frequency. Since the La Scala struggles to get down to 55 Hz, you don't want to make it smaller.

Here is a schematic of the AK-2. You can use it to chack the wiring of your modified crossovers. It is very close to the well liked AL/AK-3. The simple answer to your "problem" is to reverse the leads to the tweeters. The whole system will be "in Phase". If desired, you could then reverse the leads to the each imput terminal of eack K-horn and everything will be in "polarity". I can't imagine the latter is audible. I am in agreement with Gil. Everything is probably correct and the measurement detected a "problem" in one spot. The tweeter may not test inverted at another place in the room. This is due to the path length differences in the K-horn. Type AK-2.pdf

The promedia sections are further down the home page. We're the audio/HT guys.

I've got one in Mahogany I'm no longer using. I haven't looked in a long time, but it should be perfect. It was put on a shelf above the TV and only touched for dusting until I replaced it with a Heresy.

LSIs came with the same crossover the La Scalas came with for their year of manufacturer. The Type AL crossover is not a good sounding one. I don't believe it was ever used with the composite squawker horn (K-401). If the LSIs have the composite horn, they probably have an AL-3 crossover and it should be a good one.

ROTFLMAO!!!!

artto, you are so bad! I've been watching this thread. We're getting close, here. So, you have OLD K-33-Js? Wow! You are running an EQ through a 225 watt amp? Double Wow! You only have trouble with material that is heavy in deep bass? Triple Wow! Stop that at once! Until you have new woofers, remove all EQ below 200 Hz. You haven't told us how much is a little bass EQ, but +4 dB below 50 Hz or so could easily drive the cone beyond its excursion limits and you power amp can send more than twice the continuous power limit to the woofer. djk is tha man! He's pointed out your problems. I believe you are doing everything bad to your woofers. You have old drivers that cannot be as tough as they once were and aren't likely as tough as the new K-33-Es. I believe you are clipping the crap out of your power amp with the EQ. With speakers as old as yours, removing the woofer door a few times will surely trash the gasket and make it leak. I'd get a new pair of K-33-Es; they were $110 each just a short while ago. Then, I'd go the Home Depot and get some of the thin weather stripping they sell and make new gaskets. And last, I'd seriously examine my EQ settings. If you need 3 to 6 dB of bass EQ to make the 'horns flat in your room (and you know this from testing), use it, but go easy on the throttle and look for a bigger power amp you won't clip. If you haven't tested your room, there is a set of zipped .wav files on the Forum you can burn to a CD for testing. A RAT Shack SPL meter and its correction curve will give you usable results. Set your EQ using that and still go easy on the throttle. djk's 30Hz filter idea is a good one, too. I don't think you have a cracked glue joint (but you might), so I'd test that if everything else fails to correct the problem. Finding the leaky joint would require some thought.

Boy! My last post was a mess! I must have been in a hurry or asleep! Ears, I've heard lots of speakers that did one thing well and not another. My La Scalas tend to be like that. I still think it means the speaker in not good. My La Scalas excell at anything with acoustic instruments, but sometimes are tough to listen to with electronic instruments. I wonder if it's the recording or the speakers. I usually think it's the recording, because the same disc is not good in my truck, either.

Part of it IS technology. The materials of the woofer and compression driver cones are better than ever. With modern testing techniques, woofers can be created that have less distortion than ever. An 8" bass driver is never going to be able to perform like a 15" at lower frequencies. Mr. Paul's first K-horn was a two-way and his last design, the Jubilee, was a 2-way design. He would generally approve. He was never a fan of direct radiating bass drivers, though he built several, and complex crossovers. If a design using direct radiating woofers achieved low harmonic and modulation distortion, he would approve, I think. The current RF-series, with dual woofers, may well qualify for his approval.

What do you want for the B&K Receiver?

I don't think you can legitimately take credit for Klipsch using L-pads and ferrite core inductors. Since the schematic has not been published, you cannot claim any influence at all, assuming Klipsch has noticed you. The results, however, speak for themselves. The AK-4 K-horn does sound great.

Did she scratch behind it's ears?
