How is it going?

Many of the bolt holes and screw holes in vintage speakers were drilled by hand, without a jig, and so each one will have its own unique position. It is important to preserve that original alignment so the parts can be easily re-assembled.

Yes it is repairable, if you can get the correct replacement diaphragm. Maybe @Dave A can tell you if they are available?

If you have ever dealt with a stack of amps, a single multi-channel power amp has its merits.

Another way would be to run a nut down the threads and tighten it. Then countersink a recess into the piece of wood that sits over the newly installed nut.

Epoxy on the original screw heads might be easier (if I was doing it), but threaded inserts are a very good idea.

If you are planning to remove the panel so that the screw heads are accessible, you could epoxy the heads to the wood. Be ready to temporarily slip the side panel back over the screw threads, so the screws are properly aligned when the epoxy hardens.

Try pressing a putty knife against the upper exposed threads in the top-hat, so the screw gets jammed against the wood and turn the nut with an open end wrench or pliers. After it is loose enough, move the putty knife under the nut and repeat. On the woofer door, insert an oversize screw thread into one hole and pull or pry on that.

Yes, during the past year I have bought some woofers and compression drivers I did not need at the time, just because they were available then. The electric car industry and others are buying up all the magnet supply they can get their hands on.

Highly recommended.

Most rooms can benefit from acoustic treatment. Different methods for various frequency ranges. Some thick bass traps have smooth surfaces to reflect high frequencies.

I would be inclined to use the one on the right side of the top picture.

No one said that. A logical thought would be that if Klipsch is buying the available Celestion drivers from the manufacturer, then other Celestion buyers and resellers may need to wait.

Maybe Klipsch is buying lots of them.

@Fido, You are a good photographer.

Solid core door slabs are very good for this. Search on Craigslist or similar for used commercial door panels. You may be able to find some with a nice finish. They are heavy, so you may want to saw them down to 52" tall. Use the hinges to attach onto your wall, screwed into a solid wall stud.

Nice looking pair of La Scala.

Get your AVR hooked up to your speakers and subwoofer, run the Audyssey set-up and then listen for a while. You might be satisfied with that alone. An external amplifier may not be needed, unless you want to play it really loud.

Did a good job with the speaker cabinets you showed on another thread recently.

The good-looking cane grill color affects the camera's reading of that scene, and also influences how the mind perceives the image.

I would try the Restor-A-Finish, first on the side edge banding. I would not completely re-finish the lacquer, unless you want it stained to more closely match your Jubilee but, that might cost way more than it is worth, because the Belle has a nice color as it is.

If you have a separate amp channel for each section, then just adjust the single or double woofer SPL to blend with the subs and with the mids and highs.

I haven't even heard them myself but, just reading about and seeing pictures of the Jubilee causes my brain to generate positive superlatives in my thoughts.

The stack on the right side places the tweeters about seven feet high. That might be too tall? Get some metal mesh grill covers if the woofers are going to be exposed to party people and other wild animals!
