Full Range Speaker That Can Play Near Boundaries

Application calls for a full range speaker in the 10K range that will work well in a 13 X 17 room but little ability to move the speakers out into the space due to furniture and WAF issues. (Speakers will be maximum 18" from front wall either positioned on long or short wall). Looking for a real music lover's speaker, not a hifi demonstration. Very real midrange--lively and tonally correct with taught bass (not bloated or slow), dynamic yet non-fatiguing sound. Soundstaging and imaging are secondary to accurate tonality and lack of coloration. Suggestions?
