The M80 looks small compared to the LFR1100. It's really a beauty, I really like the way you can configure the grills. The fact that you have 3 pieces let you in control what area of the speaker that you want to showcase. The DSP module looks like the axiom amp, it's a visually appealing black box. I didn't musically compare the m80 and LFR1100 but it would be an interesting to do.

If you bought a pair, I can guarantee that you will like them.
