The M3s in my system are no slouches when it comes to low end. In my room where they are placed in troublesome corners on stands, artificial bass reinforcement was so intrusive that I initially EQed the bass way down in my receiver. It still was not correct nor satisfying.

After heeding some advice here, I then tried plugging the rear ports. Voila, that tamed the bass to where it is now a nice clean sound throughout the spectrum.

I believe that the M3 will be a great choice for your needs...
