Bro. Ray I have heard good reviews of the 12" driver used in NHT's 3.3 I can't think of the manufacturers name, but I'm certain that it wouldn't be difficult to find. Its my understanding that these woofers offer quite good performance esp. considering the cost.
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
