The K-77-M, Al's crossovers and damping your metal horns are about all of the "upgrades" that you might need. Beyond those, changing the squawker horn and driver is considered radical surgery, but possible. The K-77-M is a newer T-35A with a rectangular ceramic magnet and smoother, more extended highs (above 12,000 Hz). It can truely be considered an upgrade. I almost forgot! Klipsch has produced "Z" brackets to flush mount the tweeter with the front of the cabinet. They're cheap and not too hard to install. Which woofer do you have? There is a possibility the newest K-33-E might be an improvement, but you'll have to contact Klipsch to confirm that. E-mail Trey Cannon at trey.cannon@klipsch.com.

B.S.! Artifically adding harmonics that may have been there of may not have been there is not improving sound. Buy better recordings! John

Here's a pic of the underbelly. http://www.enjoythemusic.com/magazine/equipment/0801/coolaudio.htm Just in case the attachment didn't work. John

Mdeneen, Great! What good is a triode and a pentode in one tube? Why would I want such a thing? Do you think it's configured so it could be run in either pentode or triode mode? Doesn't pentode give more power? Each amp has 2 PCL82s. How would you use 2 of them; push-pull? Is push-pull traditionally Class B, or AB? John

If you have the "other" dimensions, you can't help but build the correct back chamber volume in a La Scala. The "compression chamber" volume is the volume of the cone pluss the thickness of the gasket; can't change that. The opening from the compression chamber to the throat of the horn is 3' x 13" in my La Scalas. I believe they're all that size. John

The comments about Al's networks on his web site mostly came from this forum. I have a pair and love 'em. John

http://www.divertech.com/antiquesl.htmlWhat say ye of this amp? What is an integrated tube? Wonder how it sounds. John

Well, It looks like I'll be forced into driving. Northwest wants $900 to $1000 to fly to LIT or SHV. I guess that means I'll drive; probably on Thursday. John

It seems my Acurus ACT-3 operates quite differently from most receivers. I run all 4 La Scalas with a crossover at 70 Hz to both VMPS Larger Subwoofers. The sub loudness settings are somewhat different in stereo, DD and DTS, but the crossover point is the same and the subs work in all modes. Originally, I ran the La Scalas full range and the subs rolled in below 50 Hz. It was great! However, through experimentation, 70 Hz sounds better and has more impact, or thump. My front La Scalas don't sit in a corner or near a wall. John

http://www.audioelectronicsupply.com/products/AEHTML/kits/se_5kit.htmlTubes can be, but you'll want very high efficiency. BTW, that's about how much I have in my Parasound amps. John

Actually you are not really biamping the speaker. To do that, you remove the passive crossover and use an active crossover between the preamp and power amps. I wouldn't expect much difference in the sound unless your amps are lacking in power and biamping provided more power for head room. Your Acurus amp is a quality piece that doesn't need the help of a second amp, so your results are not surprising. John

The common Klipsch impedance curve is another reason I favor Al Klappenberger's networks. An independant lab test showed admirably flat impedance except for the normal bass resonance peak. John

With the possible exception of bass drivers, break-in occurs in your ears, not the speakers. How many back and forth movements do you think would be required to "Break-in" a driver? 20,000? How many seconds is that with a 5,000 Hz cymbal crash? How many seconds (minutes) of about 100 Hz bass notes? John

Gil, I've yet to book a flight, but I'll fly into Shreveport or Little Rock and you're welcome to ride with me. John

The tube amp's response to impedance is one of my concerns. A K-horn's impedance varies from 4.5 ohms at 55 Hz to 42 ohms at 2155 Hz. My La Scalas will be about the same. Which tap do you use for that? Heresies hit 70 ohms in the midrange and Cornwalls probably get up to 48 or 50 ohms. John

You've got a dead short through the fuse to ground. In my experience with my old Yamaha, it would not close the speaker relays with a failed resistor in the power supply. That failed resistor took all of the output transistors in one channel when it went. You may have similar problems. You need a service manual and/or professional help. John

Very high frequency oscillation? Say 15kHz? John

Four feet will work just fine. Mr. Paul's design for false corners are 4 feet horizontally from the corner to the outer edge. He uses a pair of those false corners in his house, now. John

It turns out I thought of the name just before I read John's last reply; "The Lady of Shalott"! I guess the painter did his job. John

Either Dynamat of rope caulk will work. Rope caulk will be cheaper and easier. I've done both. John

Try Cornwalls first and Forte/Chorus second. Heresies will have to have a subwoofer to be satisfactory. I use 2 big subs with my La Scalas, even. John

Tony, I'm glad to hear you've got news. PLEASE post and send out an e-mail if you get a firm date and time. You have a recent e-mail with the fan klub's attendees and a couple of others that tried and couldn't make it. John

http://www.mrspaulwklipsch.com/ Plans are being made as we speak concerning a book signing day in Arkansas, and the latest is to schedule it to be at the Aerospace Museum in Little Rock with the governor Mike Huckabee in attendance. It should prove to be an exciting time for all! The date of this book signing has not been finalized but if all goes well with the printing of the book we are probably looking at somewhere around the 18th or 19th of March. ROADTRIP!!!!! John
