hey guys im new to the site but not new to axiom greats products. i have a VP150 in/out wall center speaker and 2 M22 in/out wall for my sides (my wife hates wires and when i did my basement i found axiom had really nice in wall out wall speakers. ) the question that i have is that i just have those speakers really. i have 2 little sony for my rear speakers that works for now til I get money for the QS8. I can get 2 QS4 v2 and a 175 v2 axiom sub for a really good price. should i buy this for just save money til get for the qs8 v3. and is there any problems with the ep175 v2 sub that i dont no about. the speakers are used but are really good cond. thx for the feed back.
