hey guys, new here, i been looking to mix and match 5.1 or 7.1 surround for my new house. so far i had the contractor do the wiring for a 5.1 set up. but 7.1 could also be fitted if i chose to. but would it be necessary? my budget is around 1 grand or so. give or take a few hundreds. i was also recommended by a friend to get polk audio speakers like the CS10 http://www.amazon.com/gp/product/B0018QROM2/ref=ox_sc_act_title_3?ie=UTF8&m=ATVPDKIKX0DER and some polk monitor 40 and monitor 60. however upon checking them out i found they were considered vintage. now i'm not really up to date with speakers but does speakers have the same rule of thumb as television like the newer the better? or is it if it's a good speaker it will always be a good speaker?
