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.

So, these are no longer AR speakers. This post should be in the "Mods" section.

And why all the advertising and links?

An interesting dilemma.  When (acceptable) replacement parts are no longer available, what do we do?  How much time, money and effort do we expend, in order to keep our AR's playing?  And at what point, are they no longer AR's?

The general rule we follow to distinguish between repair/restoration and mods/tweaks/upgrades is whether the goal is to replicate the original sound as closely as possible or to "improve" it.

So anyone who has installed film caps in their AR speakers has done a mod/tweak.

"Improve" would be subjective.

I see a lot of threads headed here.

It would be subjective if we were talking about results, but we're not; we're using the original posters' stated intent, that is, whether the goal was to repair/restore or redesign. Or, as in the case of this thread, the original poster's view of the result.

You are correct by the time I am done with them they will no longer have any of the garbage AR TSW components in them except for the Crossovers and wiring. 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 good, I have made some incredible modifications which bring them back to life. Nobody has the speakers. There's probably very few of them actually being used in the world anymore. Don't be such a purist snob.

I doubt anyone hear objects to what you are doing.  The thread simply did not belong in the AR forum.

Jengleman,

You're relatively new here and haven't learned the etiquette of this site. We don't attack other members and as Aadams pointed out, the Moderator merely moved your thread to the more appropriate section, i.e. "Mods".

And on the subject of mods, since you have all new and different drivers, the original crossover network is no longer appropriate. Crossover design is above my pay scale but I would suggest you look into designing a crossover that is suited to the AR cabinet with Morel drivers.

What a waste if time. I was trying to help others that might run across the problems I have had over the last 33 years owning these. They sound unreal and have never sounded this good.  There is no need to do anything to the COs.  I'm out!
