If you would like a slightly upgraded version of the classic American horn/big woofer concept, and you are DIY-savvy, Pi Speakers might fill the bill.

5k goes a long way with Pi Speakers.
Also, USAM has a nice used Volti Razz going for under 4k, and a nice-looking CornScala for under 2k.
Finally, there are several used Altec Model 19s available for 5 grand or less that should fill the bill.
