I have 4 Dynaudio 12" drivers that were for Duntech 2001 Soveriegns. These retail for $2,200 plus shipping. I would suggest these are a correct match for your other Dynaudio dirvers. Let me know if you are interested in the ones I have. These are about 1 year old.
Best 12" Driver?
I am upgrading the drivers in my 15 year old Infinity Kappa 7's. I have installed Dynaudio dome midranges and tweeters. They have much better sound dispersion and detail at moderate to high volume than the original EMIT's. As an experiment I have substituted top quality 12" bass guitar speakers to good effect. But, I question if I am missing some vocal nuances with them. I am looking for any recommendations for replacement 12" drivers. These are large well made sealed acoustic cabinets. I play bass and the injection molded poly 12's have always seemed deficient in the upper bass range. The current crossover is at 600Hz. I have heard good things about Focal, but can't find a dealer for them on the web. If you know of sources on the web I would appreciate that feedback also. Thanks, Brother Ray
