I'd ask DJK - Eminence made several cast-frame coaxial (C12CX and C15CX) adn I paid no more than $90 ea. on closeout -motor can run ~$1/oz at times so larger motor should not add that much. P-Audio under X-tealth offers 2226cx -- not what I'd want

C12CX had high fs so some adjustments in spider might help

12 inch coaxial:
