Since I believe a fair number of us just purchased Aguilar S210s, and I didn't find anything in the archives, I figured it would be a good idea to start a thread to collect all the reviews. So, here's mine... So far very pleased. This is a very punchy, heavy on the low-mids cab. It mates well with my SWR 350x, I bought the 4ohm cab, so I'm getting the full 350 watts out of my head, and there's plenty of headroom all the way around. The cab is, however, decidedly less efficient than my old Avatar B210 Delta - I have the master volume turned up probably a whole major tic on the dial to get the same volume. I would imagine it will get slightly more efficient as it breaks in, but think I'd likely need a pair to keep up with a guitarist at gig volumes. I've only played around for an hour, or two, but so far I can get some very satisfying tones. It pulls the vintage J-bass growl out of my Japanese Fender J, and slips down to the low-B on my Stingray5 pretty cleanly, as long as I don't have the bass cranked up. All around a very punchy, if so far somewhat quiet, 210.
