Subwoofer or New Speaker


Subwoofer or New Speaker?
Today I have a pair of Wilson Audio Cube that I use with Audio research VSi60.
Am generally satisfied with the speaker except that I feel it a little thin in the bass.
The question is. Should I buy a newer, modern speaker or a Subwoofer?
(Tried with a REL T1 it felt way too slow.)

A pair of REL T5i will transform your experience. As @yogiboy said, sealed subs, especially new higher tech ones are much faster and tighter. Obviously, room size and budget dictate your needs so look at the 7/9/S series. But 2 or more (swarm) smaller subs will be better than one larger. 
The subwoofer budget is somewhere between $ 1200 to $ 2500. Any suggestions? The room is 4x3 meters.
