I built the WJJ Hoge subwoofer with the 15" driver back in 1977 from that Audio Magazine article using the 15" driver. I drove it with a 60 watt Southwest Technical Products amp. It was so efficient that it never got pushed. I had the M&K Subwoofer test record which had howitzer shots on it. Crank it up and there was so much air movement out of the vent that it could blow out match flames. Great fun at parties. God only knows where you'd find that CTS driver today, but you can still find used Altec and JBL drivers of the spec listed in the article today on EBay. I put up a web page with a few photos of the enclosure here.
