http://www.svsubwoofers.com/subs_pb1_isd.htm I'm sure lots of you are familiar with it. I'm wanting to build a sub and I'd like to clone this thing as close as possible. I already searched this forum for info on cloning PB1-ISD, but couldn't find any info. Basically I need the enclosure dimensions, port dimensions, and the driver/amp combo. Any help would be appreciated. Thanks in advance.
