OK, I've been living with this beast for a couple of weeks now, and have been able to give it a good going over. I was on the lookout for the perfect sub (isn't everyone?) , and was impressed with what I had seen and heard in the past with Velodyne. I found the sub very easy to place, so after trying out several positions, I settled on the most convieneant spot, which was just to one side of the centre. I spent a week just running in and trying to find the optimum settings, which takes time of course. I gave the sub its first real test with The Haunting. A movie I know pretty well from past subs that I've had. What was immediatly apparent was the clarity and depth that I could never find with other subs. Chapter 17, where Lili Taylor is thrown out of bed is a good example. the whole room shook, but it was totally controlled. There was no distortion or boom. I then stuck on JPIII DTS. WOW!! the level was too high though. A quick touch on the small, but functional remote cured it. I had simelar experiences with other sub testers, such as U571, Twister and Titan AE. Awesome! I also wanted to see how the sub coped with music, although I don't yet have any hi-res stuff. It was superb, from classical to dance/ rock. Bass was extremly tight and powerfull, even at high levels. I guess that 1250w amp doesn't have to work too hard! Well, as you can see I'm impressed. The HGS-15 suits me. I decided in the 15 over the 18, as I had a Velodyne F-1800 RII before, and it was too much for my room, which isn't massive. Thanks to Eric for making the purchase possible, and providing answers and service that would certainly put most retailers to shame Rob.
