I have just been reading many of the wonderful commits about so many different subs the past couple of days, weeks and even months. The more you read the more you find out you don't know. I'm trying to keep my sub purchase under a grand. At one point I was thinking of the B&K asw750, but it's more then my budget can afford and it sounds like it won't perform as well as the svsound's. I was also checking out ACI Titan XL. It has some great write ups but, has anyone see or heard one in action? With the PB12-nsd/2 and the PB12-Plus both running neck and neck $ wise, What is the really difference? Oh the madness! If any one else has any other great ideas I'm willing to add to my confusion. Thanks, much.
