I don't know why, buy I liked the MG12's better than the 1.7's. I know most people would rather have the bigger one, but if you really like the Magnepan sound, the 12 may be better than another type of speaker that wouldn't be your first choice. If you want to stay with a planer speaker, I put a small pair of Martin Logan's (SL-3) in a room about that size and had no issues. Stand mounted ProAc's also work well in small rooms.
Magnepan 1.7s in a 10x13' dedicated room?
I'm planning on upgrading my speakers soon and want to go back to Magnepans. I'm considering MG12s but came across nearly new 1.7s on Craigs List for a good price. Problem is, my room is only 10x13x8', but I can do anything I want to it. It already has three bass traps, (two in front corners, one at ceiling wall juncture in back) and 24 1x2' Auralex absorbers spaced around the room. Floor is hardwood with a big think area rug. Anyone put 1.6s or 1.7s in a room of similar size?
