i have a swr big ben 1x18. i love the low end. but...i was thinking of making my rig abit easier to move around. does anyone know how the acme cab compare to the 1x18? will it suffice?

ACME LOW B-2? replace my 1x18?

G'Day,
I guess you're the only one who could answer that question. Personally, I bought the B2 to replace a quad box and haven't looked back since. (I must admit, it wasn't a very good quad box.) I brought in my amp and tried every quad box in the shop (they had a set up like in a car stereo store where you could patch the same amp into different boxes), I must of tried over 20 different boxes and was starting to get confused. I was getting ready to go home to ponder when I saw the B2 and said "what about that one?". To my ears (and this is always subjective) it was the only twin that sounded as good as the quality quad boxes they had there. I believe that in the US you basically buy these things via mail order and if you're not happy, you can send them back within 30 days. Try one and see for yourself.

ps I bought mine several months ago, but you might detect that I'm still raving about it!!

I bought my first B2 in '97. I liked it so much I bought three more. They give me more low end than ANY 18 I have ever played through!

how do you run your three cabs? what kind of head are you using? some one told me they use two b2s for the low end and one for the mids and highs. i have an older trace elliot ah1000-12. 1000watts could be "biamped" like so : two cabs 500watts to each, stereo full 1000watts to one cab, and then you could also have three cabs one 500watts and 250watts and 250 watts) im sure thats confusing as hell. so then i hear that having more than two 8ohm cabs will decrease the combined ohms to 2ohm hurting the head. i dont know much about biamping and what not. anyone know whats going on?
also. i heard whenever you biamp you need to have 8 ohm cabs. if you have more than one 4ohm cab you'll hurt your amp head? is that true, if so if i wanted to get multiple acme cabs, should i get the 8 ohm versions?
Andy Lewis recommends that you not biamp his cabs (B-2, B-4). The crossovers are more than adequate to handle a full range signal. Biamping would be appropriate if you were using two different cab types, say a conventional 2 X 10 and 1 X 15. Each is efficient within its specific frequency range when coupled with a properly set crossover (70-90 hz IME). The Acme Eminence 10's are wound to go low (~35 hz in conjunction with the box) but, as a result, they lose a good bit of mid response and virtually all of the high-end. That's why Andy adds a midrange driver and tweeter; the box would be essentially useless as a full range enclosure without them.
I asked Andy if two B-4's could be used as PA subwoofers. He pretty much said "I don't see why not. Why don't you give it a try?"

GET A POWER AMP that can push 500~700 per cabinet at 2 ohms. For your 1st question: Get 4 ohm cabinets and a power amp. I either run a pair of QSC 2402's(about 700 rms available but not used, it's for headroom) two on one amp, one on the 3rd cabinet OR run
one QSC with ACME's on one channel(2 ohm load) and one ACME on the other channel(4 ohm load). The amp is basically two mono amps.
Second question: only get 8 ohm cabinets if you have a TON of power.
+1. I use a CA-6 in bridged mono (1400 watts @ 4 ohm, or something like that) into an 8 ohm B-4 which is daisy-chained to a second B-4 resulting in a 4 ohm speaker load.

wish i still had mine gobs of low end but can be hi fi when you want it to be. kicking my self for letting it go. like my gs112's but loved the acme and I would still have more money in my pocket lol
Trust me...it found a loving home! Makes a killer 8 X 10 rig. The durn things weigh a ton, though.

I have a total of four B2s. Gigging I usually only use two of them. Each B2 (4Ω
I drive from each channel of a (usually) Carvin DCM1000. This gives me 350W per cabinet which is the rated power capacity of the cabinets. I have run all four on occasions running the amps at 2Ω.I have also used the cabinets as subs for my PA and they work incredibly well for that application.
I think that the 8Ω rule for bi-amping may have come from GK. Th high amps of the 800RB is 8Ω minimum and possibly others of their amps may be the same. Bi-amping is, as far as I am concerned, obsolete. Full range cabinets with built in high power crossovers are now the norm rather than the exception making bi-amping unnecessary and wasteful.

+1. I couldn't agree more. Bi-amping receives, IMHO, far more discusssion and serious consideration here on TB than it deserves. As you suggest, almost all modern bass amplification equipment is manufactured to eliminate any advantage--let alone any need--that bi-amping might offer.

meant my 210 I had before the low b4 would have worked for me the 410 was too much. I bet your rig could kill zombies with its bass!
I'll let you know after Saturday night. Mmmm....are there zombies at the American Legion?

i have a 1000 watt head. i can send 500 watts to each cab (if i wanted two). should that be enough. i mean, i know they're not efficient, but how much do they really neeeeed?

do you have a 2ohm head? is that why you're capable of running a 2ohm load, or am i mistaken that your not sopposed to go over your ohm load of your head? i have a 4 ohm head 1000watts. i cant make a 2ohm load rig can i?

Can you describe the quality of the abundant bass provided by a B2?
Is it tight, well-damped, uber-controlled bass, or pillowy, wide, and all-encompassing bass?

As long as you have the power to run the volume you need, it is tight, well-damped, uber-controlled bass.

It's been a while since I used one but I remember it having a tremendous amount of bass but being clear and not muddy or woofy like a vintage 15". I wouldn't necessarily say it was punchy though. It was bassy and clear but did lack punch when compared to say a Schroeder. I thought the cab sounded amazing on its own but in a band context, I got buried in the mix and that was with a 500 watt head running @ 4 ohms. That was my experience but others may differ. The cones can be pretty fragile too. If you drop a low B on it you can crease the cone and damage it. It's a cab that requires some TLC from the player.
