After years of lugging around 100lb speaker cabs, I decided to get some more portable speakers. Everything I read about these cabs was very positive so I decided to get one.

I was immediately impressed with the low end and volume. There has been a lot written about how inefficient these cabs are and I was expecting them to have a very low output. However, their output was about average from my experience (similar to classic ampeg cabs).

While the low end was great, the high end was a little weird. These cabs have a very flat frequency response like a good home stereo speaker. This is very different from any other musical instument speaker. Most speakers have frequency peaks and valleys that color the sound and impart their own characteristic tone (like the high mid grit that classic ampeg cabs have). Most cabs are part of your tone, these cabs are not. The acme cabs faithfully reproduce the sound of your amp. This can be a very good thing if you like the way your bass sounds through a DI. If you like the sound of your amp and cab working together creating musical resonances and overtones (the way guitar combos and stacks do), then you will probably not like these speakers.

Personally, I find the cabs to be a little too sterile sounding. They are not harsh and they have a lot of low end, but they do not have a musical tone to them. I am using an SWR SM-900 amp that has worked well with other cabs, but perhaps a tube pre-amp and QSC power amp would be a better choice for the acme B-2.
