My SVS PB12 Ultra arrived this afternoon and I have spent a little while playing around. I haven't calibrated it or anything yet, to be honest I am finding the prospect quite daunting but wil no doubt tackle it tomorrow. My initial reaction was that it really is a beautiful beast, in oak it just looks great. I have heard people refer to them as ugly but it really is gorgeous. I'll post some piccies another time. More importantly on to the sound... This is the bit where everyone writes their explicatives about how amazing it sounds etc. unfortunately I don't feel the same yet. I know I haven't set this up properly with an SPL meter but it just doesn't sound very clear to me. It's very boomy and seems to drown out all the detail. I tried listening to a load of the demo scenes suggested in the manual just to get a taster. Some sounds pretty good, better than my existing sub and certainly more effortless but I am left feeling that the really low bass is not being picked up. The 'Tuning' scene in Dark city doesn't seem to use the sub at all but the 'Icefield' scene in Titan AE sounds better than my old sub but not by much. If I turn up the gain I just get a really boomy noise that is overwhelming. I guess you will all suggest I calibrate it properly, and I will, I just hoped for jaw aching grins today and haven't had it yet. In case I am doing something obviously stupid here is how it is setup atm: Gain is set at about 1/3 on the sub. Everything else is off or set to 0. On the receiver the Front, centre and rear crossovers are set to 90hz and the sub level is set to +3db the other channels 0db. Front speakers are set to small.
