Hi everyone. The complete moron in question would, of course, be me. So for a while I've been running my Eden WT-300 as a preamp into a QSC RMX 1450 set for parallel stereo into an Eden 210XLT and 212XLT. Nice setup, but occasionally I thought it might be nice to see if there was something a little smaller (say, a good 4x10) that would have comparable volume. The concern, of course, is that I play a 5-string fretless almost exclusively (in a rock band, no less...I'm just soooo avant garde) and I wanted something that would give me the low-end frequency response to handle that low-B without massive dropoff in db. Enter, stage left, a used Acme Low B4. 4ohms, no less. "Briliant," says I, "I can bridge my QSC into one massive 1400w 4ohm mono load and I'll have headroom to spare, even for the notoriously power hungry Acme cab." Except...when I set it all up, all I got was a lot of clipping at relatively low volume. I actually got more volume running it out of one channel of the amp (450w) at 4ohm then bridged. Curious, no? At first I thought maybe it was just that I was pushing the amp too hard, as,, after all, a 4ohm bridged load means both channels are runnign at 2ohms (which they're rated for, but I'm never sure how realistic that is) Then, figuring I had just missed some crucial piece of information (being, as I've mentioned, a moron), I checked the manual and lo and behold, I think I've got it. Because my QSC only has Speakon and binding post outputs I'd been using Speakon-to-1/4" adapters when running it with my Eden cabinets, so when I set up for the Acme I just used the same Speakon adapter into a 1/4" speaker cable into the 1/4" input on the Acme. I suspect this might have been a really dumb move. The manual stipulates using either a speakon connector or both red binding posts, so I think using the adaptor to get the Speakon to 1/4" plug might have done something unspeakable bad to my amp/cabinet combo. So...I'll be heading home today with a cable that'll let me use both binding posts into a 1/4" plug and see how that goes. Anyone have any thoughts or similar experiences? J. PS A word about Acme cabinets. Unbelievable tone. Un-be-lieve-able. Imagine the low end response of an 18 with the punch of 10s. And the midrange driver and tweeter yield a really smooth transition all the way up the frequency spectrum. The Edens were all mids by comparison. If you've got the power to drive 'em, by all means, check 'em out.
