You have the earlier AR 2ax's (and some say preferred... especialy the AR-insiders over at Classic Speakers). Brown tweeter dome?
I happen to have a spare cloth-surround woofer for the AR-2ax, FYI.
simul justus et peccator
Ahhhh, you have piqued my interest.... Right now I found someone quite knowledgeable here in the ATL area who has a pair of the newer foam surround drivers he was going to sell me and take mine in partial trade. I know that with the newer driver I need to get a pair of 3 ohm resistors on the "mid" to compensate for the different design of the woofer. He says the new design is faster (makes sense - lighter weight cone, less resistance in the surrounds) and that is provides a smoother sound especially in the mid-high bass notes. What do you think and how much would you sell your spare for? Thanks.
"Faster" has nothing to do with transient response. It's really just a description of the sound, which is punchier and higher Q in the bass.
I have a pair of those woofers from an AR2a and the cloth surrounds on yours will probably need resealing to maintain the system's airtightness. (mine did) There have been many discussions on resealing KLH 17's, so do a search on those.
The newer woofer won't fit in your cabinet. It uses 4 or 8 bolts. Yours uses 6 bolts. The diameter of your basket is larger than that of the newer CTS woofer. I don't believe that the newer cone is lighter than yours, although it is smooth and stiffer. Both woofers have a free air resonance of 26 hz. Yours has an Alnico V magnet. The new one is ceramic. Yours is the better driver, but it will only fit (easily) in your cabinet.
