I recently received the Sunfire Super Jr. I won it in an AudioRevolution contest I had entered for a Sunfire pre-amp. I got second prize, and I was thrilled (not that I needed more subs, but who could not WANT another sub?).
Unfortunately, I didn't get to run it through too many tests. I was selling my Denon 5700 when I got it, and now I'm waiting for an Outlaw 950, so it may not get much more testing for a while! What I can say is that, when I opened the box it came in, I had to call everyone over. It it shockingly small, almost looks like a toy. I expected it to be small, but this was amazing. But looks deceive (and perhaps size doesn't matter after all - or at least not as much as you think!) It seems really well built, and is really heavy for its size.
As for performance, it was impressive, all least for the short time I had something to hook it up too. It had more impact than my Klipsch LF-10 (which has broken in nicely, and I enjoy), but not nearly as much impact as my Sunfire Signature, as I expected (both these little subs look huge by comparison to the Super Jr.!) It blended in well with my system, and was nice and tight. It's really a great little (really little) sub. Bob Carver really pulled it off. Theears, there has to be a closet or bathroom in your house that still doesn't have a sub, I think you'd really like one of these!
I still want to get an SVS one day, but I can't criticize this little guy, even without breaking in, it was really pumping it up.
