Ok. I am trying to improve the performance of my 2x10 and matching 15, which are currently blown. I need some suggestions about what driver to replace Eminence Beta 10s with. I am hoping to get better performance, but spend less money than the $65 a piece price for reconing. you can help me by looking at parst express (www.partsexpress.com) Also, I want to know what would be the result if I used two 8 ohm drivers instead of 16 ohm, polypropolene instead of paper cones, whatever other advice you can give. Thanks!
