Yessir.
I ran two Mesa Diesel 115's, reloaded with 3015's for a while; it worked pretty well!
However, those were big, heavy boxes despite the neo driver swap, and, they didn't have horns, and I pretty much need more treble extension than that.
Good deal though, if you don't need horns.
I used mine in a diesel 2x15 for a while and it was very good, though still quite heavy. That was long before I had the WA. I used the B1500 most of the time.
And good point on the horns. I'm thinking of having LDS make some cabs for the 3015s and am debating putting a horn in one or both. Not a fan of tweeters for fingerstyle but they're so nice for slapping.
Back on point, will the WA have enough juice to drive the 3015s to the point where the drummer will hear the bass over his thrashing, and thus know where "one" is?
....I digress
