You can buy diaphragms from either Klipsch or through a local pro sound shop from Atlas.

Not being made shouldn't be much of a problem unless it has some exotic tubes that are hard to find. I don't think it does. Seems like it uses EL-34s. They're common.

$3000 is twice too much for decorator models; maybe more. Keep looking for another pair.
The K-horn will have noticeably deeper bass than your Belles. The squawker horns in yours will also have wider dispersion at higher frequencies than the K-5-J.

The ACT-3 remote may not be able to control the Nakamichi. Mine won't control my remote light dimmer, but will control certain other light controls by the same manufacturer.
Call/Ask Acurus. They may have a code you can enter.

Heresies of about the same vintage as your K-horns will be the best match for all positions. I don't know about the typical A/V receiver, but my Pre/Pro has a 70 dB adjustmant range on speaker level. The efficiency diffeence would not be a problem.

Somebody reposted on this board an ad for a single La Scala. If placed behind a curtain, it could work.

Try putting your La Scalas closer to the wall or corner. When in a corner, the La Scala's bass begins to fall off between 55 and 60 Hz. There is not much bass below that, even in a corner.

I have not been able to hear an RC-3II, so I don't know how it will match. I use a KLF-C7 and it IS a good match, though not perfect. A single Heresy from the years your La Scalas were made is likely to be the best match for center and another pair for surrounds (that's what I intended to get) would be great. However, the Heresy woofer is not shielded, so it might cause problems with a direct view TV. Heresy IIs are still available if you want new.
Nothing succeeds like excess! I got a pair of La Scalas off of ebay for less than a pair of Heresies, so my surrounds are La Scalas, too.

Without the serial number there is no way to date them accurately. The K-77-M was used beginning in the late 70s and the Type AA was used through 1981 with a K-55-V squawker. The -V has a round softball sized grey cover over its AlNiCo magnet, not square. With the known changes, there is no telling what year they were made, even the K-77-M could be an update. If the K-77-M is original, I'd say 1977 to 1981.

I got mine from Home Depot in the weather stripping section.
Just mash it onto the outside of the horn like silly putty. Use 2 layers.

The serial number might be stamped into the edge of the plywood on the rear of the cabinet. The Type AA network is pre-82, but Klipsch didn't use square squawker drivers in La Scalas. The rectangular magnet tweeter is correct (K-77-M).

Actually, Y'all have it backward. The power amps should be turned on last (and off first) to keep turn-on (and turn-off) thumps from the pre-amp from damaging your speakers. In the 70s and 80s the gear demanded it. My ACT-3 is well behaved and doesn't need to be treated that way. This does not apply the receivers and integrated amps because the speaker protection circuits wait until the thumps are gone before connecting the speakers.
The preamp section of my old Yamaha CA-800 integrated was terrible. When using 125 watt power amps and my La Scalas, the windows would rattle.

Putting the second one 3' out of the corner will not hurt. Having the subs in different placed tends to cancel room nodes and WILL prevent both of them from reinforcing the nodes your room already has. With 2 subs in different places you will have fewer peaks and troughs in the bass response. I have mine behind the mains and in the corners. However one corner is 90 deg. and the other one is 100 deg.

I'm using a KLF-C7 with my 4 La Scalas. It is not quite a perfect match, but it is very good and fits on top of the RPTV well. I'm pleased with the results.

Klipsch IS sitting in a certian number of them for warranty and repair. After EV quit making them Klipsch wa able to buy K-77-Ms from a "friend" of Klipsch, that bought the tooling, for some years. I don't know what happened to that relationship, if anything.

Crutchfield has the highest prices going. Sometimes they are above MSRP. I will buy car audio from them, especially if it is on sale, because their techs are knowledgeable and that carry a great set of harness adapters so you don't have to cut up your factory wiring harness.
I don't care if they carry Klipsch because it'll be priced too high.

Your dealer is yanking your chain. Klipsch will surely rebuild your tweeter for less than $200, probably less than $100. Technology has not changed so much that KG4s cannot be the bassis for a great HT system, if you want them to be.

Klipsch can recone the drivers for about $75. I don't know if Orange County speaker Repair can do it. Give tham a call.
As to your crossovers, Klipsch used different suppliers over the years. I'm sure the values are the same in each Type AA. The parts Klipsch used are very durable, so, unless you are hearing a problem, you don't have any bad components. Unless you are redesigning the crossovers, you should replace the caps and inductors with ones of equal value.

Q-man,
I've got 125 wpc amps and I'm concerned about that wattage, too. Maybe for different reasons, though. twenty years ago it was a common occurance that high power amps were dirty and noisy at low output. Soundcraftsman and the GAS Ampzilla were perfect examples. I don't know if modern amps exhibit the same traits, but I suspect they do, at least a little. try to listen to the Cinepro with the provision you can return it if you're not satisfied.
Try to listen to Aragon amps. Though powerful, I believe all of them operate in Class A up to 10% or better of their rating and then Class AB up to their rated capacity. You should be able to buy Aragon for the price of McIntosh. I've listened to them on other speakers, but not my own.

There are tweaks on the BBS if you're interested, but there is nothing you need to do but play them some more, unless there is something wrong woth them.

There could also be something in the chamber between the woofer cone and the slot that opens into the bass horn. Sometimes I will hear a chestyness or extra bassiness to male vocals (listen to either od Seal's CDs). That is a resonance in the bass horn. You can feel the sides vibrating at that same frequency. Other than that, I get no unusual sounds from my La Scalas.

Not switching to Ac-3 mode is a common problem with the ACT-3. Part of the problem may be with your DVD player. Can it be set to default to AC-3 (DD 5.1) rather than Pro Logic (4.0) or DD 2.0? Sometimes a DVD will have all sorts of different sound tracks on it.
