Hey Folks I'm itchin to upgrade my cab situation in some way, but am having trouble deciding exactly what to do about it. I currently have an EV B2150M that I'm really diggin' the sound of, but it's not quite loud enough and it farts out too easily. So, I want to find a way to get a fair piece louder and a bit deeper too. I think I'm comfortably inside my zone with 15s--I've tried a few combinations of 10s & 12s and I keep coming back to 15s, so I plan to stay there but...? Generally, I'm not at all fond of tweeters either; it's just bottom and mids with some creamy dirt for me. As has been suggested to me already, I could simply throw a couple of 3015s into my EV, but, from what I understand, the Xover to the 4"(?) likely won't do well with that sort of change, so I'm hesitant to try it. or... I could look for another B2150M. my Carvin DCM 1500 will do 4ohms to each side easy enough and I'm thinking I'd be groovin' a plenty with 4x15s, but man...That's a lot of cabenit for this 51yo to haul around. or... I could look for an older Mesa Boogie 2x15. Which might just be the ultimate in tone for me (though there's many others I haven't tried). Still that's one freakin' heavy cab. or... Perhaps it is possible Don at LDS could do me a 2x15 that'd give me most/all the sound I'm looking for, in a cab coming in under 100lbs. Im already emailing to&fro with Don and we're not finished yet, so he hasn't said one way or the other as to if this can be done. If it can be though, it'd seem to be the best of my chosen options; but I'm a bit leary to think a lighter-weight cab can do what a MB Diesel 2x15 can do...tone-wise, that is. Obviously I need to make the decision myself, but I wouldn't mind a bit of guidance from those in the know of building/upgrading enclosures. So, does anybody have an opinion or two they'd like to share? Thanks to all who participate.
