@Fred from Peavey ...I am just now seeing this thread, so forgive me for being late to the party, but I am encouraged by your presence here on TB. Like everyone else, these amps and cabs have yet to land in any stores that I have seen, and although I have seen some marketing for them online, I have not seen enough, and quite frankly, the price & weight of the cabs are just not in line with the rest of the pro gear that's out there.
The fact that Peavey has had some success with the ELF line of bass amps/cabs should be a huge indicator of where the bass gear buyer's head is at, honestly. I always have high hopes for new Peavey/TE bass gear when it is developed, however as we all know, Peavey in the last 5-10 years has announced new gear and created a bit of a "buzz" and then waited far too long to bring it to market....and this is just one of their many mis-steps in trying to compete in the bass gear market. I think there are many bassists that would love to see a resurgence in Trace Elliot given their legacy, as well as Peavey...I am a long-time Peavey lover and own many older rugged heads and cabs from the "USA Peavey" days.
I also own a Peavey Mini-Mega...which given its "name/heritage" far outweighed it's performance and usefulness of its features, and its dependability has a sketchy track record. The Mini-Max however seems to have turned out to be a relatively successful head and punches well at its price point, which has always been a hallmark of Peavey gear (however the noisy fan in both heads is very disappointing) so if the power-section in the TE 1200 is same as the power section of the Mini-Mega, which is how I associate that TE Head, then I'm not excited....The Mini-Mega really doesn't "hit" like my old MegaBass or my old T-Max. as for the cabs, others here have stated, for the price Peavey is really going to have to go back to the drawing board because the bass gear crowd has moved-on and with the size/weight/performance of the Mesa Subway/GK/Bareface/RevSound, Trace Elliot is moving backwards, it seems...and I personally am not going to CARRY a heavy-ass 410 or 212 cab, when I can ROLL a much lighter 215, 212, vertical 410, or carry a 30 pound 15" cab or two lightweight 210's.
Now I'm getting off my soap-box... you don't even want me to get started on the new Cirrus bass

Thanks!
