It's here! After much delaying of dropping $400-$500 in to the perfect sub, and many months of lurking around this forum, I have made my purchase of an SVS PB12 ISD. And I couldnt be happier. As with almost everyone elses comments about SVS here at HTF, I have to say that it is beyond my expectations. I wont claim to be a Subwoofer expert as this is the first dedicated HT Sub that I have had (I know a big jump from bass in the mains to an SVS : ), but I knew what good bass should sound like, and this sub has delivered just that. I will try and give a very basic review because I cant hold back, but this is 100% in laymans terms. As for the power this sub can deliver, again my refrence point is not in HT subs, but rather in PA. I have setup the PA systems for my church, and youth group and have dealt with several good quality SUB+Amp systems. This sub has is very close to the power we would get running a pair of Eavy 18 Cabinets, off of a 500 Watt amp, and a dedicated crossover. Needless to say, I am highly impressed. The first thing that you notice, is rather what you dont notice. Not once have I heard resonance, or boom coming from this sub. I used LOTR FOTR Prolouge as one of the test scenes, and the depth at which this sub is hitting peak volume levels is incredible. You are able to feel the floor moving beneath you as things are hitting the ground. And no this is not shotty construction, but rather the "hard hittingness" that this sub is able to deliver. I am more than pleased, and cannot wait for Christmas day as I know I am getting a SPL Meter, and hopefully AVIA as well. The only "gripe" if you could call it that, is the size. It sure isnt for the faint of heart, and makes a pretty noticable imprint in a medium sized room. However when my room is "finished" it will be the only peice of HT equipment in the open, and I think that my wife can live with that. Right now my setup is a Denon 3805 receiver, and a Sony 777ES 400 Disc player. I plan on starting my thread about my HT project soon, as I have been compiling pictures of the progress in my room, and the equipment setup. I just couldnt wait to post my "SVS Finally Here" post, and join the very proud club of satisfied customers.
