The M3's put out some mighty powerful sound for a bookshelf speaker IMO (W3 is the onwall version of the M3). I find them very satisfying. They sound great at high volumes. I had them really cranked the other day with a listening distance of 20 feet. If I didn't know any better I thought I was listening to a floorstanding speaker.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
