Corey, Yes you do! It's the only one Mesa sells. Mesa went to Celestion and had to by a ton of them, since it's considered a custom order (what I read at the Boogie Board). Nobody else has them but Mesa, which is too bad cause I'd like to have a couple to try in my PRS cab! I have the V25 and the 1x12 Mini Rec cab. IT sounds good, but the 2x cabs sound way bigger. I always stack it on top of another 1x12 Avatar V30.
(Not to side track, but how's the Power Station? I actually considered one for my V25 to make it bigger and smaller, but would be torn between that and just getting a full sized Mark V).
I'm with 11 on preferring a vertical 2x12 as well, but my PRS cab isn't going anywhere.
Edit: If you've ever read the comments about the old V30s being the best speakers ever, and people saying the old V30s are better than the newer ones... well Mesa agreed and went to Celestion and said they'd use the V30 in their cabs ONLY if they got that version. Celestion said "if you buy x amount, we will make them" and so they are the only ones (I think in the U.S. maybe the whole word) that can get them. If you have older V30s, they will be like the Mesa version, and not the one that everyone else has had for the last 10 or so years (guessing at the time frame, but it's been a few years). I've had brand new stock V30s in identical cabs to compare. And if I can put aside all the politically correct BS about "it's all subjective" for a moment, I'll say "Mesa's V30 sounds better! The spike is not as icepicky. That alone makes it better, IMHO. Which is why I also prefer other V30 type speakers like Eminence Governor, over stock V30s in most situations. But it is IMO, better overall than a stock V30
