I am in the mist of purchasing a sub for my HT. However, I am stuck at a crossroad. I am looking at the Velodyne CHT 12" or 15", SVS PB1-ISD and the HSU VTF-2. All are pretty much the same price, however the Velodyne is the only one that I can actually listen to before purchasing. I have read tons of helpful reviews on all three units, however they really dont mean **** if you cant actually listen for yourself!..imo. I would greatly appreciate all the helpful replies. Thank you all in advance.
