You could use Bose cubes as "reference" speakers, if you wanted to. When reviewers talk about reference equipment, they generally refer to gear they own that suits their tastes (and sometimes budget). So, if a reviewer is sent a new pair of speakers to write about, they can compare it to their own system as a "reference".
The M3 sounds GREAT, and has acceptable bass for a small stereo system. Goodsound.com used the M3 as its reference speaker for over a year...it will do nicely if it fits your budget and tastes.
