Alright i need to upgrade either my front two or rear two speakers. I have the polk rm6750 and it was good for a while but i think its a bit to weak. Now i got a $100 bonus so i found these two polk bookshelf speakers. I want to know if i should upgrade front first or rear? does it matter? and also will i notice a big difference with these over the polk rm6750?
or Bestbuy has these for $99.99 (pair)
