I ordered 2-10" DD EROM 9510 surrounds for a recone i was doing, the diameter is too large for what im trying to use, so... any builders out there, i just received these yesterday so they are brand new. I paid $34 all together to get them so $30 shipped and their yours. I would also be willing to trade for 10" high roll surrounds or similar surrounds that will fit a 7-1/4" diameter cone.
