So I posted this in my 'what's my ampeg' thread but it got buried. So I'll try again for some sage advice: I'm trying to figure out what to do about my rig: Hartke 7000 SVT 410 HE Crate 115 JBL I feel like the 15 is the weaker cab, but the 410 is no great shakes running alone (mono). Reading the specs off Ampeg's website, it seems like the SVT 410 HE doesn't have a lot of bottom end. And actually it seems like the 15 has better high end response if I'm running them bi-amped and switch the hi and lo outs. The thing that's got me thinking is that one day I was sick and lazy so I didn't lug my 15 to the rehearsal studio, and just plugged the Hartke in to the SWR 610 cab they have there, mono. It kicked ass, much better than anything I've been able to get out of my two cabs. So what I'm wondering is, would I be better off ditching them both and getting one more modern, lower extending 410? Or something like the 610 or a Henry 8x8? I play heavy rock, funk etc. Spend lots of time on the Low B and want it all (punch, growl and depth). It seems like the amp has what it takes. If I traded both for say...an Acme Low B4 or some other solid 410 with good extension, I'm wondering if I'm going to give up anything, aside from a little volume.. Thx in advance for those of you who have experience with similar setups..
