Hey all, I have been thinking about changing my sub for a long time now. I've been dreaming of getting an SVS sub for maybe a year and am now trying to get a job while in school to get one, hopefully be able to get one in a couple of months. So I have a few questions for you HT dudes out there. Alright. I currently have an Energy e:XL 12 (I think that's the model) and I have been pretty happy with it minus some things I don't like about it. Firstly it has a great look and it sounds nice too. But the port noise bugs the heck out of me. Now the port noise only has been apparent now that my family decided to switch the furniture around. Ok...well, on to the questions about SVS. The living room we have now is not all that big, but we are moving and I am pretty sure the house we do pick will have a big living room. Our current living room is about 12ft by 13ft. Not that big at all but when we move the living room will probably be around 20ft by 20 ft or a bit bigger. So here are my questions: 1) Have any of you SVS-owner's out there experienced any sort or form of port noise? If so how bad? 2) How would an SVS compare to my current Energy Sub? SVS models like PB1-ISD, 20-39pci or pc+, or PB2-ISD. 3) How would a PB2-ISD compare to dual PB1-ISD's or dual 20-39pci's? I think that is it for now. The reason I asked question #3 is that I have been wondering if dual PB1-ISD's or dual 20-39pci's would be similar or better to a PB2-ISD. Because if the former is similar in all aspects to a PB2-ISD it would benefit me because I would be able to buy 1 sub now and then when we move another sub to go with it. But if the PB2-ISD is better then I'll probably just have to save more cash. But that's it for now. I can't wait to see your replies and I thank all of you ahead of time for helping a crazy college kid out. Thanks and God Bless.
