I listen to classical music on 2.1 system.

My sub is circa 1979 and needs replacing. So I am thinking of trading my M80v3's (I could use more bass and they are in excellent condition) for 2 M22v4's and the EP500v4.

I have no LFE outlet on my present stereo amp (circa 1988). Can I still connect the sub to my amp? Would my system's performance be improved? Your advice is appreciated.
