Eminence Beta 12CX - 250W Coaxial 12" driver
Please note this unit does not come supplied with a compression driver! Usually this is fitted with an ASD1001 - but this is not the only tweeter that will fit.
Recommended for professional audio as a mid-bass in either vented, or sealed satellite or floor monitor enclosures. Also works nicely in vented two-way enclosures used for small coverage areas. Perfect for a compact monitor wedge - but don't forget the HF driver to go with it!
