You want golden ear.
Joseph Audio Profiles are in your price range new and should be no problem driving them with your amp. Not technically full range, but they’ll put out a good amount of quality bass for their size while providing a good portion of the performance of the much more expensive Perspectives. Best of luck in your search.
On second thought, do you have any subs in the system? If not then add a pair of REL subs, with REL’s you are in for a treat. You will experience a whole new layer of tonality that brings music more to life. The imaging along with every detail from top to bottom will improve as well.
There is no other sub that will provide seamless integration as REL using its unique high-level input.
