I'm selling an Acme Low B2 and Low B2W (the subwoofer version of the B2). I'm looking for around $1250 for the pair, or I would consider a trade for a 410 such as Epiphani, Markbass, EA, Bergantino, etc.
The current prices new are: for the B2 - $1,350.00 and the B2W - $1,050.00 so $2400 all up
They're great for 5 string, and were designed with the low B in mind (hence the name), you'd be hard pressed to find a cab that sounds as good that low.
Keep in mind that Acmes are VERY power hungry and as both cabs are 4 ohm your amp will need to be able to handle a 2 ohm load. I wouldn't recommend anything under 1000 Watts to run them both at the same time.
Here are the specs for the B2 from the Acme website:
Model: Acme Low B-2 Series II
Frequency response: +/-3 dB 41Hz to 22 kHz -6 dB at 31 Hz
Power Handling: 350 Watts RMS continuous
300 Watts sine wave @ 30.87 Hz
Sensitivity: 93 dB 1W/1M
Impedance: 4 ohm
Dimensions: 23"H x 15.75"W x 16.5"D
Weight: 50 lbs / 23.2 kg
Specs for the B2W (the subwoofer version, which is essentially the B2 without the midrange driver and tweeter) from the Bass People website:
SPEAKERS: 2x 10"
POWER (RMS): 350w
IMPEDANCE: 4 ohm
FREQUENCY
RESPONSE(Hz): 32-1K
SENSITIVITY(Db): 93
DIMENSIONS(cm): 58/40/4
WEIGHT(KG): 23
And the piccy:

There is some wear (but not heaps) which is purely cosmetic and this does not effect the performance of the cabs in any way.
The Acme website also has a lot of great info about their cabs – http://www.acmebass.com/
Inspection can be arranged in Ashfield, Sydney.
Let me know if you've got any questions and I'll be happy to help.
