Well, after a bit of two'ing and fro'ing, my replacement SVS 20-39PCi arrived yesterday morning. My trepidation in plugging it in was immense but, when i flicked the switch from auto to on the red light turned green and the beast was alive! My first job was to get it 'near' right with some music so I played a few tracks and just adjusted the gain, connecting at the low level saves any messing about with crossovers etc so this was relatively easy to get about where i wanted it with the music I was playing. So, after that I thought 'Lets try it with some films' First off was Attack of the Clones, the opening scene where the ships come over the City. After experiencing this scene with the sub at the gain level I thought was about right, I soon changed my mind and had to turn it down a bit. The flat literally shook After a bit af playing with that scene I put on Matrix Reloaded, an early scene when the ship approaches the docking station, again, the bass was incredible. Not an audible bass, but the kind of bass that just changed the air pressure in the room so much the sofa was vibrating like mad. The difference between this and my old Rel Q200e is astonshing, it essentially goes lower better, and that about sums it up. My final test was the opening to Toy Story 2, something that I had heard on IanJ's system, and what started all of this upgrading off I was hoping that I would be getting the same kind of performance with mine that Ian gets with his in this scene, and, I was not disappointed in the least, the bass was so in tune with the rest of the speakers that it just blended in beautifully, shaking the room for short bursts and more prolonged bursts when needeed to, not a sign of audible distortion. So, the last two days I have been fiddling around trying to get it sounding as good as possible and at the moment I and over the moon with my new toy. My parents came round last night to have a listen and they left with massive smiles on their faces, and me, in fits of giggles at their reaction If anybody is sitting on the fence, wondering whether to get one of these or not.....don't wait any longer. SVS had to ship me out a new sub to replace a faulty one and, although the wait was excrutiating, it was well worth it, the guys at SVS couldn't be more helpful!
