Well, after going back and forth and looking at different options I finally purchased a sub. Funny thing is...it is not the one that I originally thought I would buy. I ended up with a Velodyne CHT-15. To make a long story short, a friend of mine is an a/v equipment distributer. Their main lines are B&W, Velodyne, McIntosh and Yamaha. All of my Yamaha gear has come from them. I stopped by the other day to see what they may have in stock. Basically, they will sell me whatever they have in stock at a really good price. I was hoping they might have an HGS series sub in stock. They had a couple of older Velodyne subs and a B&W ASW 600 and the Velodyne CHT-25...That being the case, it was an easy decision. I really did not want something quite so big, but let's say, the price was right. I brought it home and I have been VERY suprised at how good it sounds. I spent a good bit of time today setting all of the levels and getting everything balanced. Another friend brought his SVS 20-39 PCi over to do a comparison. To make a long story short, we both agreed the Velodyne actually sounded better. It had more punch, low end etc and it cost me less to boot. Needless to say, I am very pleased with the sub and it has more headroom than I could ever need.
