I really like my Yamaha DXR10 speakers. The benefit of the 10 is that you can lay them on their sides as a monitor. I have done many solo and duo gigs with the speakers behind us on the floor. We hear it nice and full and the smaller room is still filled with sound.

I also own the RCF ART 310a 10" speakers. Very vice tone and a bit lighter than the Yamaha. Less wattage than the Yamaha but nice power and tone for up to 100-150 people.
