I think the hesitation for some people is that ML is a national brand and Seaton and other companies loved by AVS members are not. In real world the Seaton is the superior sub...we both know that but he has to get comfortable with that notion on his own. If multiple glowing reviews won't convince him, not sure an audition would either. Even an SVS sub would destroy the ML and I favor Seaton and JTR over SVS. I came off a highly regarded Paradigm Sub 15 (and servo 15 before that) and my JTR subs are more musical and much more tactile. Perhaps you could poke around the Seaton thread and see anyone local would be willing to give your friend a demo.
