Best 2W Speaker under 1500

Odd as it may sound I have never owned a pair of 2 way speakers. But I want to put together a system for my den which is about 10x15. I plan on using an old CAL icon mkII that has been sitting around gathering dust as my source. I plan on using a tube amp running about 50-70 watts. Can anyone give me an idea what kind of speakers to demo? I would like to get a speaker that has a good bass, but a non-fatiguing speaker is important as well.

thanks
