One of my speakers in my GK MB210 combo blew out and the replacement speaker from GK runs about 140 dollars. The Eminence Delta10B speaker can handle more watts, has a bigger magnet and a larger voice coil. It also is a lot less money. About 80 dollars. Any reason I should not get the Delta? Is there any reason a cabinet with one GK speaker and one Eminence speaker would not work?
