That's somebody's 2003 K-horns from the odds and mods Forum.

That's supposed to look bad? The real problem is the scaling of the vertical scale. You can make a speaker look great or bad just with the scale.

I flush mounted my tweeters; it's worth it. The squawker horn would require removing a lot of material. I lined the opening with heavy felt from Home Depot.

You probably had a bass heavy system before and became used to exaggerated bass output and inadequate mid and treble. You can wean yourself by adding bass with the tone control and slowly backing it off. The best test is to listen to voices and adjust until they sound perfectly natural. Chesty female voices will quickly show exaggerated bass.

Hi, Gil! Actually we don't disagree much. I am not a big subwoofer fan and think they should be used only to fill in where the mains cannot go. That should give greatest fidelity. The increase the power handling of the mains, the sub crossover should be set as high as possible, like Gil says.

You don't say where you live. There is a small speaker manufacturer in my city. He ran response curves and T-S parameters on 2 Heresies for me for $70. It took about an hour.

I bought the last K-55-V/PD5-VH diaphragm from A Pro Audio shop In Nashville called Techstar. Ask for Sam. A few years ago a new PD5-VH was $160.

I'd cross it at 45 or 50 Hz. EVERY speaker is easy to blow if you mistreat it.

Russ, The Big Klipsch Heritage speakers run 6 ohms up to the squawker crossover. The equation for total impedance is 1/A + 1/B + 1/C + .... = 1/Total. Add up the reciprocals of all of the speaker's impedances and then take the reciprocal again. Do not run high power into a combined impedance less than the minimum rated impedance of your amplifier for one pair speakers; damage may occur. Low power into a low impedance should be safe (that won't cause too much current flow or heat). The equation is based on nominal impedances and results in nominal combined impedances. Be aware that a K-horn or La Scala is rated at 8 ohms nominal but varies from a low of about 3.5 ohms in the bass to 32 ohms in the midrange. Other speakers are similar. Since your amp is only rated down to 6 ohms, it is not a powerful or high quality amp and is likely not suitable for what you want to do. Be careful with it. A 70 volt distribution system could be very useful for what you want.

It's probably your room. That speaker wire could not possibly help the situation. Try some plain large guage copper wire. The old, original Monster wire is plenty good. I wouldn't think it was the Denon, nor the lightspeed what ever it is. Assuming that is your digital connection to your Denon, that is. However, you should try a normal, good quality interconnect between the DVD player and the Denon. The electrical to light and back conversion is not always up to the quality of the direct connection.

Austin, By your description, you have the AlNiCo K-55-V and K-77. The K-55-V is really an Atlas PD5-VH that, after a time, was specially modified for Klipsch. The K-77 is the early E-V T-35A. The dates and lore is a bit vague, but the AlNiCo T-35As were supposed to have been hand selected by Klipsch for performance. All T-35/T-35A/T-350s use the same diaphragm; it is still readily available. Diaphragms always include the voice coil. The PD5-VH is still in production as is its diaphragm. The 2003 Heritage drivers are newer versions of these 2 drivers, but due to the production techniques used now, are about 1.5 db less efficient. That requires a new crossover. The tweeter crossover point has been lowered, implying the squawker MAY not be able to go as high as it used to. All of this makes the new drivers incompatible with the old crossovers, but not as drastically as you were lead to believe. Four years ago, Klipsch was willing to overhaul the same drivers in my La Scalas, should they need it, for about $76 each. I hope they have not decided to stop that service. However, the work can be done by any competent technician at any good Pro Audio shop. The K-77 diaphragm replacement appears to be idiot-proof. I know from experience that the K-55-V diaphragm requires a little care to get just right. Still, this work (minus the testing)is of the D.I.Y. level of complexity. You almost cannot overhaul one and fail to meet new performance. I have not experienced the sort of answers from Klipsch Customer Service I have heard reported on this BBS. It disappoints me that different people get different answers and different levels of support.

The K-33 woofer is a 4 ohm woofer. So, a Cornwall is 4 ohm speaker for most of the frequencies where there is music, especially high power region. That's why the 4 ohm tap works best.

I got a Model 1 for Christmas. It IS a great radio. In fact, I have the best radio in the office!

Condorflyer, Klipsch will rebuild your drivers with OEM parts and test them to see if they meet specs. I doubt that they will supply your with a curve to prove it, but you can ask. How would you know the curve indicated original performance? The 2003 drivers use the same diaphragms (squawker and tweeter) as your 60s/70s drivers. Unless they have been dropped, or subjected to long-term high power levels, they will meet original performance with new diaphragms. Klipsch charges about $80 each last time I asked. There are not any NOS Klipsch Heritage drivers around anymore. Since the original diaphragms are available, that is not relevant. In the worst case, your K-55-V and K-77 AlNiCo drivers can be remagnitized to full strength, but it is rare to find the capability and it is not cheap. Klipsch can no longer do it, but there is an outfit in the plains that can (Iowa?). I believe they bought the old Altec tooling and are producing Altec parts.

The AL is my least favorite crossover network. Personally, I would replace them with Type AAs or even home-built AAs made from the highest quality components. If you are not into soldering, Al's ALKs are an outstanding choice and his workmanship is excellent. Though I have not heard them, the Type AL-3s were designed for your driver set and are also supposed to sound very good.

With certain tones and female voices, I can (well, could) feel the throat of my metal K-400 horns vibrating. Early on, I posted questions about it and soon after wrapped the horns with Dynamat. The result was a much calmer, smoother, more relaxed sound. I may have been one of the initial causes of the discussions about damping. Several don't like the effect saying it makes the sound too lifeless. I do like it and believe it is impossible to overdamp any of the horns, or cabinets. The structure should not contribute any thing to the input signal. The unmounted K-400 makes an outstanding bell, delivering a clear tone in the 500 Hz range with several overtones as the fundemental slowly dies. Mounting it to the motor board kills almost all of that, but there are still bits of it left. Use Moretite, aka rope caulk, and if you don't like it, it is easily removed. It is apparently as effective as the Dynamat and much cheaper.

75 to 85 dB average, depending on the music.

"ignorance" I believe we have finally found the single subject on which you are qualified to speak, and in fact, know it all.

Al-Qaeda was found in North central Iraq. Hussein has anthrax of the same strain sent in the mail just after 9/11. I don't require more proof. No one I have ever spoken to believes Hussein was *directly* responsible for 9/11; your data is false or the poll question was skewed. He may have provided training and funding. Who do you think you are to demand more or to sit in judgement? Blinded, ear-plugged (to protect their hearing from the din of the A/C) Al-Qeada captives doesn't even sound close to mis-treatment. Go sniff some more glue.

Try one of these: http://www.metermantesttools.com/products/xtseries.asp I have a 27XT; it cost $125 + tax. It does not do temperature, maybe one of the others will.

You cannot normally use two amps on one driver. It sounds like each of the amps are fighting each other due to some internal problem. Try it with just one channel hooked up.

Check your wiring very carefully and test the system with another amp. Many Carver-designed amps have the reputation for being grenades. From here we cannot tell whether it is the amp ir speaker. Assuming it sounds normal at very low volume, it may be the amp.

Generally, there is nothing that makes one cable good for digital and another one not. However, taken to the extremes, a digital signal is a set of square waves and square waves are made with lots of very high frequencies. So, a cable can be made better for a digital signal by reducing parallal capacitance and series inductance so it will pass VHF signals.

Did someone call you anti-American? I think you are more the victim of anti-American biased news reporting than anything else. I'm sure you haven't seen the video of U.S. and British soldiers giving out food and water, or the one where an American soldier, in obvious pain, carries a bloody Iraqi soldier to safety. I doubt you heard the interview with the U.S. sargent, blood dripping from his arm, that captured 4 Iraqi soldiers, wearing civilian clothes over their uniforms, that had just tried to blow him up. He could have just blown them away with his assualt rifle, but his was first concern was to get them safely off of the bridge and ouf of the fire zone. We've seen dozens of grinning Iraqi kids shaking hands with the soldiers and dancing while the soldier hands them candy. These stories are so common on our news as to appear to be the biggest thing going (obviously it's not). We are not capturing women and kids and using them bullet shields, either; nor are we showing P.O.W.s on TV. Had we only wanted the Iraqi oil, we would have stayed 12 years ago. Try to remember that almost all news outlets have an adgenda and will selectively report the news to support that adgenda. I used to think our news outlets were bad, until this war. The 49-country coalition has reporters from all over the world travelling with the troops and sending back video that clearly puts the lie to much of what is on Al Jezeera.
