I had a pair of T-120s back in '85. Those things were bullet proof. We tried to destroy them and failed! I had a mixing board in the audio path and someone blew a whistle into a microphone. There was some kind of protection in those T-120s - you could see light glowing inside the cabinet through the bass reflex port when you blew the whistle! Anyway

So - we are happy, and we are listening to some refurbished S-40s. Now - I've got to decide what to do with them. Regardless of who ends up with them, I still would like to fix that gouge on the top, but I'm not sure how to proceed with that. My brother-in-law the general contractor is coming over tomorrow, I suppose I should pick his brain

I remounted the tweeter (with new screws, 3/4" #6), then slid the new foam sheet into the cabinet through the woofer opening. I pulled the foam up to the top of the cabinet with one hand while sort of shielding the crossover network with my other hand. There is just enough extra length on the foam sheet that it folds at the bottom of the cabinet

Thanks, Evan. I let them play at moderate level for 5 hours while I was gone, and now I'm home again and listening to Beethoven's 9th on the S-40s. Very pleased with what I've heard so far. So then, after the Americanization of the back side, I flipped them over and soldered the new wiring to the drivers. And then I made another minor mod

Next I Americanized them with a new terminal cup. Sorry if that offends. The new terminal cup has five way binding posts and is gasketed.

I replaced the old wires with some new 16 gauge mid-grade stuff (from a speaker supply outfit). And of course I replaced the old caps with the giant Solen caps. I resoldered. Much easier than the 3-way S45-2s I did last month. Lastly I put some hot glue on the sides of both caps, plus the top, connecting them. This is the other crossover, the one I

Next I desoldered (as best I could) the existing network and removed the wires and capacitors.

The internal stuff is now done. Yesterday I had taken both apart. Today I started by marking one of the crossovers with a "what gets wired where key." (For those who can't wait until the end, yes, they sound fine. Listening to "Abbey Road" with the S40s right now. The bass on these S40s [and my S45-2s] are just wonderful. Won't

Claus: Very interesting approach, but.... "...Listen for scraping sounds....if you hear scraping...." If you hear scraping, haven't you just damaged the voice coil?

Made some more progress on the S40s today. Pulled everything out of each cabinet and made cutouts for the new terminal cups. The rear of the S40 cabinet is 3/8" thick thermoplastic, likely PVC. As it is a thermoplastic, I had an interesting experience making the cutouts. As the cut was made (with a jig saw, using a "multipurpose" blade
