Maybe it's just because I got a lemon, but the SB12 just felt rather muted/dull and didn't have much impact/output. I guess I just expected more.
I had (still have) a Martin Logan Abyss which I really liked in my 2.1 channel PC audio setup. I found a good deal on an SB12 with the intention of replacing the Abyss. I fully expected the SB12 to be a better sub in terms of output and sound quality, but it failed to beat the Abyss in both cases. At first I figured it was because the SB12 had yet to be broken in, so I made sure to use it for a few weeks before making up my mind. A few weeks later, the Abyss still clearly sounded better. More musical with a more visceral impact.
I got the Reaction pair several months later as I turned my small upstairs room which had primarily a storage space into a mini theater room, and dual 212's fill up that small space easily. I tried the SVS up their compared to just a single 212, and it was really no contest. The Reaction hit harder and deeper. Not really a surprise. The Reaction is a bigger cabinet with dual 12" drivers while the SB12 is a very small cabinet with a single 12" driver. Both subs use medium excursion drivers. It's only the "Big Boy" SVS subs that use their high excursion drivers (basically their plus and ultra subs).
I'm pretty sure the PB12-NSD (and now PB2000) is an excellent sub with a healthy amount of output. I think the refurb PB12for $499 or less right now is an amazing deal. However, I just feel the SB12 has too small of an enclosure to make an impact in a home theater setup, even in a small room that I tested it in. It's a very good looking sub and I really wanted to like it (and expected it to be good), but I was just let down.
Honestly, when I sold the SB12, I gave a couple potential buyers listening tests with some movie scenes. Whenever I did that, I made sure to stow the Reaction subs out of sight out of fear that the potential buyer would ask me to try them out in comparison. Had they heard the comparison, I wouldn't have been able to sell the SB12.
