I will go strongly against the grain!!!! You have outstanding monitors. Bass from a seperate sub combined with your 22's will sound far better (in my opinion/experience) IF!!!!! you have properly set up active sub with appropriate equalization software. That doesn't mean you need super expensive DEQX or TACT hardware. Several subs come with equlizattion and set up microphones to be used with a laptop to accurately set up according to your room acoustics and seating position. I think rane has some ....Outlaw as well in fact they have now partnered with HSU and I beleive have subs which satisfy this purpose.
