You should be able to achieve good bass performance in a room of that size. Specified frequency response is down to 28 Hz with the M-1 and A-1, while the U-1 goes a few Hz lower due to the rigid steel frame. Performance in one's room will be determined by placement and furnishings as well.
The room dimensions should allow placement several feet out from the wall behind the speakers. The speakers can be located fairly close to the sidewalls due to nulls which occur on the sides as a result of dipole cancellation. Room treatment may be as simple as some large plants or other items to diffuse the sound where first reflections occur. Corner bass traps may be desirable. Absorption behind the speakers can enhance bass response by virtue of reducing dipole cancellation.
I have heard a U-1/UB-1 system in a room approximately 30'Lx20'Wx14'H on several occasions, and the experience is remarkable. The UB-1 subwoofers extend response down to the low to mid teens but are not essential.
I don't know if you'll hear any difference between the M-1 and A-1. They use similar panels, though not interchangeable, and everything else is the same except the frames and trim. Some people prefer the A-1 due to the generous use of wood, which they can select at time of ordering. The U-1 is a different beast altogether, with its 3" tubular steel frame which grabs hold of the (similar) panel and enables more pinpoint imaging and a bit more bass extension, allowing the speakers to sonically disappear even more so. But the M-1s and A-1s are no slouch!
The amplifier you describe may well be adequate. How much power it puts out into 16 ohms may be of interest with regards to the bass, as the impedance of the speaker is high in this region. If you care to say what the amplifier is, or email me offline, I'll be happy to comment on its suitability. I am a Sound Lab dealer (located in the Chicago area) and am somewhat familiar with which amplifiers work well. Meanwhile, if you have other questions, please feel free to ask.
Best of luck!
