I 'm going to get a couple bookshelf speakers and a sub for 13 X 20 room.

Amazon has Mission speakers for a good price right now. From what I've read these should be very good, but I don't think they are available locally to hear. The alternative is to go with Polks ar JBL which I have heard and can get locally..

I'm thinking of the m31s or 32s.

Can anyone who has experience with this series of Mission speakers comment on whether they would be a better choice?
