Being a shill for the website

, I would recommend the
Infinity Primus 362's, on sale for $400/pr
shipped. It would be better if you could listen to them yourself, but in lieu of that, they are
superbly engineered for the money and will do very well on what music you seem to like. Place them as far away from the side walls and front wall (behind the speaker) as reasonably possible.
A pair of
Earthquake S-12's, around $840/both for primarily music listening, though they will provide plenty of output for HT effects if you expanded later, even in your decent sized room and keep your budget well under $1500.
If you could add a 3rd, inexpensive (<$200), compact (maybe 8") sub under an end table by the sofa, better yet. The more LF sources, the smoother the perceived bass..and less excursion/potential distortion for each individual source. Being in very close proximity, the small sub need not have to be played very loudly, just enough to add some smoothing of the total LF response.
cheers,
