By small, I am taking you to mean small bookshelf models (14in X 10in X 10in at most).
I have used a lot of small speakers in small rooms over the last few years. Most cost a few hundred bucks (which is why I experiment so much), with three being more expensive. Realize upfront that speaker placement will be a big determinant on how good any of these speakers will sound as in my experience smaller speakers can be fussy. Also, don't go too cheap on the cables (speakers and equipment) as I found in two instances that that can be a noticeable determinant as well (really couldn't believe it either).
