Looks like M is 1972. John

There is a pair if La Scalas on ebay (100 miles north of me, starting at $1500, "buy now" at $2250) signed by Orndorf Hertz. The seller says that is PWK. I thought Mr. Paul used his own name on speakers. John

The Type AL xover is probably most of your problem. It is overly complex, unusually designed and does strange things to the response of the individual drivers. It over controls the system. My rear La Scalas had Type ALs and I though they were squawky, ill-defined in the lower mids and had a screech at high levels. I put ALK xovers in them and almost all of that went away. Damping the horns cured the rest. They are smooth and unaccented, now. The Type AA xover with high quality components is a good sounding xover, but it will have to be adjusted a little for your K-55-M squawker. My front La Scalas have modified Type AAs. Other than the Type ALK, I like the Type AA and Type AK-3, best. The AlNiCo tweeter IS a little weak in the upper treble and might also be contributing. The newer K-77-M tweeter is smoother and has more output in the upper frequencies. John

The KLF-20s will have a lot more low bass than the Heresy. They are moderately more efficient, too. John

I'm not sure Orndorf Hertz is legit. However, the O. Gadfly Hertz is, so Orndorf MAY be PWK after all. I've got an e-mail to the seller. She's ~100 miles away. John

The woofer in the Belle and La Scala sits behind the "V" and fires rearward. The sound is split into 2 paths and bends around to the front. The Belle is VERY similar, but the point of the "V" is cut off and the horn is stretched wider, but shallower. John

your KLF-30s dont *produce8 hiss, they are so efficient they show off the hiss in your receiver. Most A/V gear has it and is must be a product of the DSP. I have some trouble with it in my ACT-3 pre/pro. Acurus says it is a function the gain required to meet some Dolby Digital requirements. All you can do is try a different receiver until one suits you. John

The '99 drivers have all been unchanged since 1982. The fiberglass squawker horn started well after 1982, but I've never heard when. I doubt you'd improve much going to the aluminum squawker horn. If I had them, I'd listen to them as is for about 6 months before changing a thing. Only make changes to address a shortcoming you hear. I have the metal horns in my La Scalas, but damping the tweeter and squawker horns would be first on my list (use rope caulk from Home Depot, it's in the weather sealing dept.), then I'd tightly stuff the HF cabinet with polyester fiberfil from Walmart. Then, make sure the seals between the bass horn and the corner are good and it sits tightly in the corner. Finally, look into Al Klappenberger's replacement crossover. Your's should have Type AK-3 xovers. They are said to sound a lot like Al's, so consider it last. John

$3,000 is a lot of money over here, too! Hah! Hah! Hah! John

You have an open voice coil. It can be repaired for much less than a new one costs. The diaphragm can be bought from Klipsch or from E-V (for a T-35A). Most pro audio shops can get and install the diaphragm. John

Maintaining the tonal balance all around is important, though less so in the rear. For that reason, I'd go for KLF-20s or 30s. John

Not normally. John

Bucking Magnets MAY be available, but all of the drivers will require sheilding or bucking magnets, one. Distance is still your best bet. John

A bunch of nice pictures Doug! There were several I didn't take, so I copied them. John

My Hope Pics are at: http://www.cdc.net/~colt45/klipsch/ They are big files so expect a slow download unless you have a fast connection. John

Mine are tall and refrigerator-shaped. A cube is nearly a sphere and encloses a lot of volume for its size. John

The break-in is required to push out all of the non-music electrons! John

The KSF 8.5s are pretty good sized towers aren't they? If so, I'd set them to Large. Your receiver is setting the Low pass for the subwoofer, so I'd set the sub to a somewhat higher frequency so its xover doesn't cause uneven repsonse when added to the receiver's. 100 Hz should be O.K., but the frequency should be selected by the performance of your other speakers. John

You're on the right track with no Mortgage! Get a copy of "Audio/Video Interiors". They usually tell who designed the Hts shown in the mag. John

I just got back a few hours ago. The trip was GREAT! It was beyond our wildest dreams! We got our pictures made with Mr. Paul. Miss Valerie is sweetest grandmother you'd ever want and a great hostess. She practically worships Mr. Paul. Trey, Matt, PhilH, Jim Hunter and everybody we met at Klipsch were Class Acts! We got several nice souvenirs. And we spent quite some time with the Jubilees. They are smoother than the K-horn and very powerful. I think they will further the "Legend". Pictures at 11. John John

You have a mormal pair of LATE Heresy Is. That squawker is used in the H IIs. The early H Is had K-55-V squawkers. john

The K-33-E, the latest version, is optimized for the Belle/La Scala/K-horn back air chamber and compression chamber volumes. It is said there are few better for use in folded horns. If you have a -B, the -E is a nice upgrade. Al Klappenberger's xovers are flexible and very sweet sounding. You'll like them and they will help you match the output of other squawkers. You HAVE wrapped the squawker horn and tweeter with damping material, haven't you? Have you tightly stuffed the HF cabinet with poly fiberfil? John

I guess I can understand "ugly". They're supposed to be sort of avant-garde; I think they are striking. They are over simple in my book. My Act-3 has no frelling tone controls! John
