I have been using an Eden WT550 into a 4 ohm Eden 210 XST. Last night I lugged this simple rig to my gig. When I got there, the opening band had a bassist that played upright into a small pre-amp into a QSC power amp into an Acme Low B. I got to chatting with him about the Acme and Eden stuff. We had a few minutes before we started to set up, so he and I did a little shootout of the 2x10 boxes. Those cabs are not even in the same league!! That little Acme just blew away the Eden hands down. I've always had sooo much trouble getting a decent tone/bottom end out of that XST. I could never really hear it. I did not change any amp settings, but kept unplugging the Eden box and plugging in the Acme, comparing the sound. The tone of the Acme was thunderous, clear, and very hi-fi. The Eden is very mid heavy cab to my ears. In the comparison, we had the Eden WT550 set flat and just kept switching the cabs. I kept hearing stories about the Acme and it's efficiency, but I found hardly any difference at all in comparing it to the Eden 2x10. In fact when the Eden gave up volume wise and started farting, the Acme just bloomed and got better sounding and louder. Now if I can only compare a Bag End 210 with the Acme, I can narrow down my purchase decision. Has anyone out there compared these 2? Now I understand what all the Acme fuss is about.
