Give yourself the gift of efficient full range speakers, sized for your space, which is _____?
That will avoid the NEED for subs (cost/placement/blend issues).
Will also keep your power needs lower. smaller power needs = less money, less size/heat/weight, more placement options, much is gained besides saving money.

New or Used? Caution with return privilege's can often get you quite a lot of choices.
Personally, I avoid esoteric brands.
happy hunting,
