Woofer equalization has been around for quite a while. It basically provides a frequency dependent boost to the signal to level out the response curve as the woofer rolls off. The Marchand product is a good one. But you may not get the results you a looking for. First, the Heresy starts to roll off around 100 Hz and is down by 3 dB by about 65 Hz. and falls off rapidly after that. So even with equalization, you may not be able to get flat response as low as you would like. Second, equalization comes at a price. You are going to be operating closer to the mechanical and thermal limits of the woofer under all operating conditions. If you like to crank your system, this may not be a good idea. IMHO the best approach to dealing with the Heresy's limited bass is to use a good subwoofer. Interestingly, most powered subwoofers have similar equalization circuits built into them.

Just be aware that the Thiele/Small parameters for the K-22-K don't reflect all the other versions of the K-22 used in the 20 plus years the Heresy was produced. They are all over the place. And they don't make nearly the difference in performance in a sealed box that they make in other alignments.

Tantalum caps don't like reversed voltages. The epoxy encapsulated ones go off like sky rockets when reversed. But I don't think they are used much in speaker crossovers.

AFAIK the only thing missing is the low end. You need a good subwoofer to go with them.

"...more dangerous down there." Paticularly if they are Eurocopter EC120s with the diaphragm in the fuel controller installed backwards...as two of our local deputies found out...

Its not just SAC bases you have to watch out for. I saw pictures of the aftermath of a guy accidentally landing at Palmdale (Skunk Works, Phantom Works and who knows what else, big hangers with several floors underground) instead of General Fox Field nearby some years ago. Two vehicles full of young men with M16s met the pilot about the time he realized he wasn't where he thought he was and explained that he was not going to fly the aircraft off the field. His response reportedly was something like "F*** you! I'm going to leave, now." They pulled out chain saws and cut the wings off his airplane. For that matter, last time I heard, you really didn't want to land at any military base that isn't joint use without prior permission. At best, you will be required to provide proof of liability insurance for some large amount and get written permission before leaving. More likely, you will be required to truck it off. And that was before 9/11. As far as the danger of flying in small planes goes, I've certainly come closer to getting killed more frequently when I've been in small planes that in large planes. It is really dicey around airports that have accelerated training for foreign nationals working on their commercial or ATP ratings. Hmmm...I remember a friend coming back from a business trip on which he had a near midair collision. He said he reported to air traffic control. The conversation went something like this... Pilot: "LA Center. 1234J. I'd like to report a near midair collision." Center: "1234J, did you get the tail number?" Pilot: "No, but there was a beautiful, blond with blue eyes and diamond earrings in the right seat." Too close for me.

Don't know about any link to Klipsch. Soundscriber was a company that made voice recording systems that used vinyl or acetate discs.

I have a Piper Arrow (single engine) and a Piper Aztec (twin engine). You've heard the definition of a boat...hole in the water you throw money into? The only thing worse is an airplane. Apparently, I ain't none too bright!

3 dB down point of Heresys is about 65 Hz. Twice that is 130 Hz. That is a higher than necessary crossover point. They start to roll off around 100 Hz. That would seem to be a good point to start with. 80 Hz seems to work well with my setup.

FWIW I avoid any seller who hides feedback. And I am sure lots of other folks do, too. So, I don't think the seller is really getting away with anything. Which looks worse to you, letting people see the bad things others say about you (with or without a response), or covering them up? Definitely use a credit card if you can for eBay transactions. A charge back is one more recourse you have. PayPal can come through for you. But sometimes it won't. The credit card company can charge back to PayPal even if the seller's account is closed. Luckily, I have never come out on the short end financially on a eBay deal, although it has taken a bit of work on a few occasions. That said, I figure the possibility into what I am willing to bid. Hopefully, if I do lose money on a deal, I'll still be ahead overall compared to buying elsewhere. BTW eBay is not always the best place to buy. I just bought a new TI 83 Plus calculator for less than $74 plus tax locally, retail after in-store discount and rebate. Even on eBay, at the best prices I have seen over several weeks, I couldn't save enough after shipping is added to make it worth taking the small risk of non-deliverly, late delivery, damaged delivery, etc.

You have some of the last Heresys made. K701 horn...

Any easy solutions? For what? You don't have a problem. Where I live, the nominal voltage is 120V. The power company considers voltage satisfactoy if it is within +- 10% of nominal (118V to 132V). This is typical. Your gear won't have a problem with the voltage you report if it was designed for use in the U.S.A. Be aware, that if you measure the voltage again, it may be different. Voltage can and does vary over time. Shouldn't make an audible difference in your sound unless the smoke gets out. You can get a UPS compatible with any standard voltage in the world. Clean power? Even with "pure sine wave" ouput, any UPS of the kind we typically think of for home use is going to generate some noise of its own noise.

Welcome to the forum. Don't be afraid to ask questions, even if you are not quite sure how to phrase them. We all started somewhere. DJ and jazz/classical musician, interesting...

Yes, never played LPs sound pretty good. Too bad they don't stay that way. You opened factory sealed Beatles albums? Do you have any idea what some of them may be worth worth unopened? I don't supposed one of them is "The Beatles Yesterday and Today" with the Beatles in white coats and parts of baby dolls, the so-called "Butcher" album cover?

There are at least 3 versions of the K-700. My 1965s and 1972 have horns similar to the thick one in the picture. But they do not have the little ears for the mounting holes. The mounting holes are in the corners.

It doesn't take much thinner to clean the gun. We normally just sprayed it into the air for a few seconds. Haven't bought one recently, but I think a decent respirator with organic cartridges and paint prefilters should be avaialable for $30 or so if you look around. Just make sure it fits well when you use it. This normally precludes beards. And you still want the best ventillation you can get. If you are going to save used thinner, store it in a metal container, like the metal can it came in. A glass jar is not a good idea because it may break if dropped or hit.

You know, you can get a real good finish from water based acrylic wood finishes nowadays, even in black... As far as getting high breathing the thinner, adequate ventillation or an appropriate respirator will fix that problem. A respirator is also a good way to keep paint out of your nose, lungs, etc. Yes, you need to clean the gun when you are done. I never cleaned an HVLP gun. Should be similar to a high pressure gun I think. Clean the cup with thinner. Save the thinner for reuse. The solids will fall out to the bottom of the container. Put the cup back on the gun with some thinner in it, then run the thinner through the gun. You think it is bad when what you used sets up in the gun? Try a catalyzed finish with a 15 minute pot life.

Link didn't work, but by spider webbing, I think you are referring to what you see when the glass substrate of a LCD flat panel display breaks. I have seen this in laptops subjected to abuse, like being dropped. It is a possibility in any LCD flat panel device. I have never seen it in a flat panel desktop display or TV. But it is a possibility if things are flying around your viewing area. Do you have a three year old in your life who is likely to take up golf in your viewing area? Is so, I would have similar concerns with a plasma set. Of course, with a three year old, nothing is safe. I read a post somewhere from a guy whose kid decided to wash his rear projection set. Didn't work too well afterward.

Haven't head much about dlp color wheel being noisy. I am sure it could get noisy if the bearings went bad. All of the rear projection units produce some noise because of the cooling fan. Manufacturers try to minimize the noise. But, practically, if you move air, you will make some noise. Some folks with dlp, or for that matter, LCD or LCOS, rear projection systems plug the unit into a small UPS so it stays powered long enough for the bulb to cool down. But I don't know if this is really necessary.

Yep, looks like someone blew the K77 and replaced it with a cheap piezo tweeter.

The weapon Crowe is charged with crimally possessing is the telephone. The Feds don't give a sh*t who possesses a telephone.

Hmmm... Maybe you should have left them there until they disappeared. Then it would be UPS's fault they were lost...

How would you know which one was wired right (on a non-Klipsch speaker) if one went in on a positive signal and one went out? The only difference between a Klipsch Type D network and a Type E network is woofer phase. After releasing Heresys with 8 ohm woofers and the Type D network, Klipsch decided the speaker sounded better with the woofer phase reversed.

Check out www.avsforum.com for all you ever wanted to know... There are certainly a lot of things to consider when chosing a technology. Not a lot of moving parts in DLP besides the fan and color wheel unless you count the million or so tiny, hinged mirrors on the chip. But all those tiny mirrors...makes you wonder doesn't it? My guess is that if they work when they get to you they don't have any greater chance of failing than the active elements in a LCD or plasma set. I think once you get past the infant mortatility stage DLP bulb life is reasonable unless you have a power failure which the set is on and lose the cooling fan while the bulb is hot. Bulb prices have come down to around $250 or so. By "spider webbing" do you mean "screen door effect"? There is a lot to be said for CRT rear projection. The biggest downside is the size of the set. The other rear projection technologies allow for a smaller footprint.

A digital audio cable really carries digital data, not audio. The CD data rate is something like 1.4 Mbps. A cable must be able to handle frequencies (actually it is a bit more complex but frequencies will do for here) much higher than audio to do this. At these frequencies, the cable starts to act like something called a transmission line. The electrical characteristics of the cable have to be matched to the transmitter and receiver to achieve efficient transfer of energy and prevent reflections that can garble the data. What this means in practice is that the equipment is designed for use with a coaxial cable with 75 ohm characteristic impedance. Your plain old audio interface does not have these requirements. It operates far below the frequency where transmission line effects start to be seen. Plain old shielded patch cords work just fine. But you can use coax if you want. You just don't need to use it. The characteristic impedance is irrelevant in this case. The coax becomes in effect just fancy shielded cable. FWIW you might not even need to use coax for your digital audio signal if the cable is less than several feet long. If the cable is less than a significant fraction of the shortest wavelength it needs to be able to carry, you can pretty much ignore transmission line effects.
