Magnepan for a small room

Pastor, you room is pretty small - probably too small for dipoles to work effectively; at least without major and costly room treatments.

I have used a Peachtree Decco (previous product to the Nova, 50W per) w/ Von Schweikert VR-1s and it was a great match. The VR-1s do need to be out from the wall a bit to sound best.

Other speakers I could recommend are Linn Kans, Dynaudio Audience "W" series, NHT 1s - all designed to be placed right up against the rear wall. Also you might consider the ERA 4/5s, distibuted by the same company that sells the Nova, and Dali Ikons.

And for something completely different, how about an old pair of Klipsch KG-4s? They are available very inexpensively, are efficient, have great bass (compared to the smaller monitors I mentioned previously) and can be easily placed within 12" or so to the rear wall.

do you think a floorstanding speaker would overpower the room? I don't want to over kill the room but I just want a natural bass sound

I would say that it depends on the speaker, but most full range speakers are going to be very tough to place in a 10x10 room. Besides size you have the shape (square rooms are very tough) thing working against you.

Small monitors or highly efficient speakers designed for SET amps might be your best options.
