How do you like the Sonic 610? I've alway enjoyed Sonic's cabinets that I've owned (a ported 2x10, a sealed 8x10 and currently have a little ported 1x12 and some PA cabinets) and think that they sound great and are a great value (especially used).
Perhaps 6 months ago, I almost went crazy and bought four 610s as I knew of one in the Chicago area, one in SE Wisconsin and two in Cedar Rapids (IA).
I really like it. It is definitely a good value. Aside from the strange ohm rating (5 or 5.3), it is an awesome cab. It isn't a big deal but if it were 4 ohms I could have an even 2 ohm load.
I wasn't expecting astounding results from a bargain cab, but I love what it has done for my rig. Paired with my Avatar B212, my rig was super loud and sounded better than ever. I haven't played very much with the 115, but what I have heard was nice. The Sonic 610 is definitely here to stay.
Was the Sonic 810 pretty compact? My 610 looks pretty small and the other cabs on the site also look pretty small. I'm glad to hear that you are pleased with your Sonic cabs.
It's a good thing that you didn't splurge on the 610s from Cedar Rapids, otherwise I wouldn't have one right now.

I too have considered grabbing the other that they had. I'm all set for cabs right now but if I ever had a chance to grab the other Sonic 610 they have in stock, I'd jump on it. Four 610s would be sick! I'd love to see and hear that.
On a side note, if you ever get a chance to deal with the Cedar Rapids MusicGoRound, do it. The service has been some of the best I've ever experienced. I received email responses very quickly (within 10 minutes, typically), the staff has been very friendly and helpful, and it was just an overall positive experience. I'll be looking in that store for used gear when I need it.
