I'm thinking of putting my Acme's to work as PA subs, since they've recently been unemployed due to the recent appearance of a Berg HT112 in my rig (immaculate conception? close..) Since we play medium to small clubs and I've been wanting to get my drummers kick drum out of the mains, I think the Acme's could work fine as subs. But there are issues, of course: I'm attempting to convince said drummer that we should at least *try* the Acme's for one gig to see how they'd hold up. He is arguing (validly) for the use of 18 inch drivers for use as subs, mainly being that they move more air. I can't disagree with, but I figger since we're only playing small rooms, the Acme's in that scenario, would work fine. He also is claiming that running his kick thru 10-inch drivers is 'compromising' his sound. My claim is that running the kick thru our mains is compromising the rest of the bands' sound. (our mains are two-ways w/ a 9-inch horn and a 15 inch woofer, driven by a 800 watt EV Dynacord amp. We have had problems with distortion when the kick is fairly present in the mix.) He's been hitting me with specs of cone excursion, freq. response, et al. ad nauseum, which like I said I agree with, but given our current situation, I think our sound would improve with the additions of the Acmes as subs, mainly because we'll have a separate amp driving the B-2's and our EV amp will be working less. Can anyone throw something in the ring that would help illucidate this mess? Oh, and if this is the wrong forum, then I can glady move elsewhere.
