Iím currently using two of the B460 clones from the Audio article by Greg Timbers: http://www.lansingheritage.org/html/jbl/reference/technical/1983-subs.htm . I built the version with the 12 cubic foot cabinets and have been extremely pleased with their performance. Iím moving into a larger room and was planning on building one of two more of them, until I saw the ASB7128 subwoofer on JBLís site: http://www.jblpro.com/catalog/general/Product.aspx?PId=300&MId=2 . While it doesnít go as low as the 2245H subs, it looks like I might be able to EQ it to achieve low bass because its output at 25Hz is 135 db continuous (141 peak!!!).
My goal is to save space and I thought maybe one of these with EQ could replace four 2245H drivers. Does that make any sense, or am I way off base in my thinking? If anyone has any opinion on the quality of bass I might expect from a high output PA sub, Iíd appreciate that too. I expect not too many, if any, has heard this beast, but I welcome even your educated speculation.
I also havenít been able to find a cost on this thing, so that might rule it out for me once Iím able to get one. In the meantime, Iím just curious as to what you all think.
