dynuaudio c-1s in a small 10x12 room?/amppower?

Bad, bad idea. The C1s need a lot of room to breathe and for the drivers to integrate. Even a 14 x 16 or so room is too small for them. They are a bold sounding speaker and need power (important) and lots of room (more important).

The suggestion to find a smaller front ported speaker is a good one.
