well, out of curiousity, and pure GAS, i got myself a pair of Acme B1's the last week, and after a good long testing period that consisted of three long rehearsals, and two semi-serious sit-down taste tests with a bud at a local rehearsal hall, here are my findings: as y'all know, i'm very enamoured of my Epifani 1x10 ultralite pair. no where else have i found a 1x10 pair that sounded as huge, yet are as light as these puppies. but with a pair of 1x10 Acme's, i was reminded of how only Acme's 10" cabs can really hit a juicy thick Low B and make it punch like a body blow to the midsection. lets get right to it. specs wise, you can check the websites for the Epi 1x10 UL's, and the Acme B1 1x10's. you've already heard me go on and on and on about the Epi's, so i'll go into the Acme's a bit. FYI, the Acme's i'm demoing are 4 ohms each, side ported, and weigh 10 lbs. more. the weight is a bit noticible, but still, nothing to write home about. and unlike the fully sealed Epi, the Acme has a right sided port that's maybe 5" in diameter. not a big deal, but in a cramped situation when i'm literally knocking my knees against the drummer's floor tom, the Acme can be a bit problematic in finding enough room to let the port breathe. right off the bat, the Epi's are by far LOUDER. at a rated handling of 250-300 watts vs. the Acme's 175 watts, and with a 99dB sensitivity vs. the Acme's 90dB, the Epi simply crush in the volume catagory. i could easily play with a friend's funk outfit with 3 piece horn section and "loud-ish" drummer. the Acme's, on the other hand, just barely make it past that burly drummerboy. but also keep in mind, the Acme's are 4 ohms each, instead of the usual 8 ohms that the Epi's are. thusly, the Acmes add up to a 2 ohm load vs. the Epi's 4 ohm load. figure it'd make the most of my Clarus. but even despite the impedence and wattage, the Acme's just arent nearly as loud as the Epi's. tonally, things get interesting... With my Kern IP777, the Epi 1x10UL pair shined, and IMHO, a Kern/Epifani setup is to die for. they just complement each other soo beautifully. that dark, yet thick and rich milkshake like kern tone, accented by the more clear as a bell, sweet and chewy Epifani sound made for an addicting combo. But, the Kern with the Acme sounded a little too laid back for me. not quite as inyourface or chewy as with the Epi's. rounded edge feel, with a slightly attenuated midrange sound. i never understood why Vanselus always insists that the Acme's to him sound a little too pretty and restrained, and i think i'm starting to understand that. not that this is a bad sound, but i just preferred the more upfront, chewy and sinewy texture the Kern had with the Epi. the abundance of mids in the Epi were very apparent, compared to the Acme's. still, both sounded fantastic with my Aguilar DB680 preamp. i could dial in whatever tone to compensate for whatever with the parametric EQ thru the Acmes. for the Acme 1x10 pair, add some narrowly banded low mids for punch, as well as some wide banded upper mids for cut and chewiness, and you've a killer fingerfunk tone. if there ever was a preamp to be mated to the Acme's, its the DB680. but in general, i can hear a very chewy midrange and airy crisp highs in the Epifani's, which make for a detailed sound. very present, and yet still open sounding. the Acme's on the other hand, are a tad darker, and have a rounded blunt edge feel to the highs. not quite as soaring or defined and detailed, but more sweeter and rounded off. both cabs are still forcefully punchie in their own ways! now, the really interesting part... the Epi's only reach a depth of 45hz. kinda makes the low B's to my Elrick and Sadowsky sound more flabby than tight, cause i seem to hear more of the string's rattle and extraneous noise, rather than the low B itself. i'm being a bit obtuse, but hopefully y'all get the picture. whereas the Acme's seem to make the Low B free from the excess string rattle, due to the more prominent fundamental string tone. the Low B is by far punchier. quite amazing actually, and was instantly reminded of my old B2 2x10. the Low B tone on the Epi sounds fine, and is pretty nice actually. had i not ever heard the Acme, i wouldnt been perfectly happy. Heck, who wouldnt?!?!? its a freakin' Epifani after all! its just that the Acmes make the Low B sound sooo much more natural and "tangible". Andy really makes you rethink how your Low B could sound like, and all from two small 30 lbs. boxes! moral of this story? if you like a punchyouinyourgut Low B tones with an overall pretty and sweet bass tone, the Acmes are very hard to beat for you small to really small club goers. also, the price on the Acme's are really great, too~! a killer punchie little Low B rig. but if you need a more present midrange and airy top end in your sound that happens to also easily do battle with a moderately loud drummer, and you appreciate an especially super light carrying weight, only the Epi's will do. hope this all made sense given my sleepy exhausted state. i just got back from a quick rehearsal with the Acme pair, which followed, taking out my little cousins who are visiting from DC. i had the tones of the Acme still fresh in my mind, so i wanted to get the writing ideas down before i forgot.
