Hi guys,I.m in the process of upgrading my mirage(om-2oo)sub.I have revel 50-a mains.I know the reviews on the b15a are very good,also the dd-15(velodyne).It seems the dd-15 has a nice advantage.automatic room setup,where the revel has the disc.Which if any, is the better sub Sound ect.29 to 3200.00 is a bit of coin to dish out.Any thoughts greatly appreciated,Thanks Don
