Additionally, you would normally require about double the surface area of the original cone. So, 1 12" woofer, 2 12" radiators, 1 15" woofer, 2 15" radiators, etc. In this case, that would be 4 18" passives radiators or 2 36" passives radiators! I'd say stick with the factory recomended bass reflex port (rectangled curf or round flared), 35Hz or 3db down, 31Hz at the lowest. Running the specs on this driver in bass box pro looked good down to 31Hz using a flared (outside end) port.</p></blockquote><p></p>
