I've always been interested in this cab (the original Mesa version) and recently noticed there is a small company (Boogafunk) making these enclosures again since the EV12M 200w speaker has been reissued. Anyone ever play bass through one of these cabinets? I was thinking of picking one up if it could be used for both guitar and bass (where a 1x12 would be appropriate).
Can't comment on the cabinet design. The speakers themselves can be great - at least the original ones. I have a Carvin 2X12, sealed cab about 3/4 the size of a full size 4X12, with EVM12L speakers that I like with high powered guitar heads or lower powered bass heads. I use it with my D180, which is both of those things. I run this setup fairly bass-shy, stressing midrange, and my basses have very light strings. I'm afraid to pump too much bass through them at high volumes. Reportedly Steve Harris has used them in his Marshall cabs. I suspect that from a technical standpoint both the cab and speaker are terrible for bass, but I tend to let my ears decide what sounds good to me rather than just look at specs.
I have been using EVs since the TL designs were first released in the early 80s. They were a nice, small & affordable cabinet & have served me well over the years. I have only recently retired my 606s for bass & still use some 806s (w/horn) for a small PA cabs. But, I have played bass through the 12s on rare occasions & IMO, they are really not up to the task for anything but low cafe volume. Loaded with the EVMs, they are not really all that light either. There are better options out there these days.
+1. When issued circa 1974 the excursion of the EVM was competitive with almost any twelve available, but today it's not even average, and it's guitar oriented specs choke off response below 200 Hz, so it's easily outperformed by drivers half its weight and a third its cost.
I liked playing through a buddy's rig which was a pair of the 1x15 cabinets and a pair of the 1x12 cabinets (I used my Music Man HD-130, and Al used an old black-faced Bassman). But that was so long ago that I don't really recall much in particular about the sound, and I do recall they were heavy... and we weren't loud at all. jte
