I read the review of the M3 speaker at Soundstage. How big of a room are these small speakers suitable for?

Sorry it took us so long to get back here! In regard to the recommended room size for the M3s, it is a powerful bookshelf design, with very good efficiency. It will tend to work better in large rooms than a lot of tower speakers will. Given sufficient amplifier power, the M3s could work very satisfactorily up to a 1000 sq. foot room. Thanks for the question!

I'm sorry but did you mean to type 1000 cu foot room? 1000 sq feet would be a room 100' x 100'.

I dont want to step on feet here but a 100X100 room would be 10,000 square feet 10 times the size mentioned. a 1000 sq. ft. room is more like 31X32 to give you a more accurate visual.

Wow!

I didn't even catch that. it WOULD be 10,000 sq. Good call!!

I do think the M3's would work in a room of that size. My former living room was about 25 by 30 and the M3's definitely filled it with a 70wpc amp.
