Guest dogmeninreno Posted April 13, 2004 Report Share Posted April 13, 2004 I have several 12" woofers that are marked with the AR logo but also have a part # 1210003-2A. What are these and are the suitable for replaceing the AR3a and AR9 woofers? Dale Link to comment Share on other sites More sharing options...
ninohernes Posted April 13, 2004 Report Share Posted April 13, 2004 They look like AR-58b woofers, but they would most likely be ok for an AR-3a. Link to comment Share on other sites More sharing options...

If it has the flat-side frame, which I could not positively verify in your picture, it is the one. It is for all intents and purposes identical to the early woofers, and can be used in any of the AR speakers specified for the 2000003-0 or 12100003-0 woofer. The Tonegen woofer came out sometime in the early to mid-1990s, and was used to replace the original woofer, and it works fine for all the AR 12-inch speakers with the flat-side speaker hole.--Tom Tyson Link to comment Share on other sites More sharing options...
Guest dogmeninreno Posted April 13, 2004 Report Share Posted April 13, 2004 Thanks Tom, They all have the flat sides. I will try a couple of them in some AR3a's...Dale Link to comment Share on other sites More sharing options...

tysontom Posted April 14, 2004 Report Share Posted April 14, 2004 >Tom, Here is a pix of the critters. Thanks, DaleDale,That's definitely the one, and certainly "good-to-go" on the AR-3a. By the way, are those a couple of AR-3a crossovers on the floor (in the picture)? I had some original early concerns about the relative stiffness of the suspension on these Tonegen woofers, at least compared to the earlier original AR woofers. I think, however, that it makes very little difference except perhaps full-excursion harmonic distortion, and the old woofer *may* or *may not* be superior (Ken to tell). For all practical purposes, there is probably no audible difference in performance. Incidentally, Ken has one of these Tonegens (like the one in your picture) to test, and as soon as I can get some original AR-12Ws out to him, he'll be able to compare some more AR woofers, time permitting.The Tonegen woofers are obviously less "hand-made" than the original AR woofers, and the manufacturing quality is obviously very high.--Tom Tyson Link to comment Share on other sites More sharing options...

The xovers are from some 4x's but I have some 3a's which are removed from the cabinets.
