    This may be a better solution. My thinking was that the 4408 may be better for THX than 4412's, since low freq. is pretty much bypassed. I would appreciate some opinions about this.

    yep :D We do that too. I would have mentioned it, but thought Corian would be more resonant. There's quartz as well. Zodiac, Silestone, Ceasar Stone, etc.
