I had never heard of this brand before, but there's a store here in Richfield called Audio Perfection that carries them and I was really impressed with it. It's the entry-level sub for $1,100. I think it was the Q150E Mk II. I went there looking for a sub around $500 and very quickly was looking at this one. It sounded excellent with plenty of sub-40Hz punch and rumble. My HT is small - about 12'x14'. The $600 sub they showed me was a Martin Logan which showed off some great sound as well, again, it was the entry-level ML sub.
I need a great sub for both movies and music, but the more I think about it, the more I think I'll be listening to music...
I can swing the $1,100, but I also don't want overkill. Advice?
P.S. When I asked them about Velodyne, they scoffed at it...
