Just got the sub in today, it came packed in 2 boxes and very well padded in foam. SVS gets bonus points for the way they package and present their products. Anyhows, when I initially saw the SB-12_NSD sub, I was surprised at how small it is, just 14 inches cubed. Frankly, it looks neat and vicious at the same time with the grill. After placing the sub in a prime corner spot, I got a tinge of buyer's remorse worrying if this sub would be able to hit loud and fast...more on that in a bit.
As to setup, room this size is 12.5 X 10 X 8 = 1000 cubic feet. I am in between speaker upgrades and am just running a stereo setup with Polk Monitor 40s, no MCACC calibration yet on my Pioneer receiver. The sub is dialed in between 10-11 o' clock on the dial as recommeded in the quick startup paperwork. I used a monoprice subwoofer y cable to connect both sub L & R rca inputs to one sub pre-out cable. I checked and the loudness level is higher with the y adapter vs not using it, so any owners of the SB12, definitely recommeded a y splitter.
I started with a Playlist of mp3s that have ample low end, an eclectic mix of trance, house, reggae, drum and bass and some rock. I realized that I can't really crank the sub until I break it in a bit, so I dialed down the listening volume to a low but revealing level. As I listened to some very recognizable tracks, I found myself impressed at how transparent the sub blends in, its fits in smoothly, has a clean tightness that sounds unique and different from my old ported sub. Surprisingly the detail is damn good, very musical and with a seemingly true flat frequency response, this a positive for me, I like my music and moves to come across as intended by the mixers and not with excessive coloration.
Some of the more revealing tracks, particularly drum & bass and some reggae tracks, show a nice refined low end with distinct and clean notes, bass punctuations are clean with no noticeable muddiness. I'm hearing details on the low end that come through on this sub with a cleaner tightness and quicker attacks than compared to my old ported sub. The difference between ported and sealed is starting to become more apparent to me.
This little sub has shown some strong dominance in my small room and I haven't pulled out the big guns yet. After some more break in, I expect to thrown in some action blurays to see how it does. I am impressed at how well this sub blends with my speakers, it might be that the sealed sub sound has better transparency, but there are tracks that I can't really tell where my sub ends and my speakers begin. With my old ported sub, it was a lot more obvious.
Impressive little sub so far, thumbs up from me
Here are some pics, I know my stereo mains shouldn't be on the floor, my stands are being used in another bigger room, eventually I want to get 2 floorstanders to stand where the monitor 40s are and drop in a center channel:
