The Danley Sound Labs TH-SPUD has some rather impressive specs. 19 Hz – 125 Hz - 3 dB, 94 dBSPL, and 123 dBSPL Peak is quite good considering the use of two Tang Band W8's. I'm looking forward to your testing of the clone against the 10" Titanics, and the Rythmik Audio DS15. I assume your cabinet size will be the same as the TH-SPUD, 11" x 48" x 45"?
