Curtis may not appreciate me sticking my nose in, but here goes anyway. Yes, of course Curtis knows he can get a recommendation from Hsu. Anyone can. The problem is - there are only so many places he can practically put his sub, given his life and his room. I've been there. It may not be optimal, but it isn't bad. In my room, I know my Hsu sub is probably not placed optimally, although I have spoken to Dr. Hsu about it. What Curtis did is a little different than what you did. Yes, you both compared subs. However, you advertised it as a comprehensive review, with blind testing, frequency sweeps, and listening in (at least) two rooms. Curtis simply posted his impressions. He listened to two subs in the same location. It may be that the SVS wasn't placed in the best position. It also may be that the Hsu wasn't placed in the best position. OK, those are his opinions. I don't think Curtis is making any claims that his comparison can be applied to someone else's room. You are making that claim, I think.
