Any thoughts on my comments about bandpass designs being easier to damage? That is a main concern with the Yamaha sub.
Given that this is a powered bandpass sub designed by a reputable manufacturer like Yamaha, I wouldn't worry about it. They will have all kinds of protections built in.
I should mention that I've heard that Cerwin Vega sub, and I thought they sounded really good. It was a band playing Island/Reggae using triggered drum samples - and had a good punchy sound with a genre noted for low end. The room was rather small, so don't know how they'd stack up against your other choices.
