I have an update. I have replaced the Sunfire Grand Cinema amp. I purchased 2 new Crown XLS 2502 Drive Cores. One for each speaker bi amped. This seems to be the proper amplifier solution for these speakers in that there is so much power in these and they do not get hot. What an improvement!

Sony hap71es... Through the years I have always had to use an equalizer to get good sound from my source. This Sony takes all my music files and does nifty tricks with my files and as with Spotify balances, filters, and re samples and all the tunes sound absolutely perfect. It is an amazing machine. There is no need to mess with treble, bass, or toggles...but I don't have any of those anyway...

The morel subs will not fit into the 910's. I purchased new subs that are available that are OEM replacements.

Yes, I am running 2 channels into each speaker. This is the amp to run these speakers!

I am running a Sunfire Grand Cinema Signature architects choice (425 amps into eight ohms) biamped into the 910's. I use a Sony HAP server. My preamp is an Arcam Av8. Over the last 30 years I have tried numerous configurations of amps mono and duels into different preamps wiring etc.

Simply Speakers is now selling new AR replacement parts. Instead of putting the Morels into my TSW 910's, I purchased new Woofers from them. https://www.simplyspeakers.com/acoustic-research-replacement-woofer-12100032.html

Ok.. here to help.

I linked the speakers so that others can have an idea of what goes in these. Since none of the speakers are available, and nobody knows how to rebuild them, and the tweeters never could handle any power to make them sound great.

I am the original owner of some 1987 TSW 910 speakers. I rebuilt them about 15 years ago. The tweeters have blown. I replaced them with minimal effort with Morel matched high energy tweeters they were about $600 a pair. They have totally opened up these speakers far exceeding the original tweeters that came with it that are unavailable. These speakers have never had enough power to run them until now. I am running an Arcam AV8 as a preamp. My power supply is a Carver Signature Sunfire Cinema Grand. For my data source I am using a Sony hap71es. The system is finally what I always looked for and has come alive like never before. It has so much reliable solid clean powr that never clips never distorts. Very impressive. Next I will replace the 4 woofers with Morels..about $2000 for all.

I purchased these for replacements. They fit the hole perfectly, and seem to be a great improvement. https://www.parts-express.com/morel-st-1108-supreme-1-1-8-soft-dome-tweeter-pair-black-faceplate--277-096

One of the tweeters was a single magnet replacement by AB from 2002. The other one was a double magnet replacement from AR original 1990's. I just hooked them up to a Sunfire Grand Cinema Signature Architect (newly purchased) and loaded Van Halen up to almost full level. That is how I blew them.

I am going to try some of these in the hole. https://www.parts-express.com/morel-cat-308-1-1-8-soft-dome-tweeter--277-082

I have a fully restored set of AR TSW-910's and the tweeters finally blew. Does anyone have a good suggestion for a replacement for them?
