what is the easiest way to upgrade my setup from 7.1 to 9.2. i wan to add a sub and two standing front towers without having to buy a new receiver, but will to add amp or what you suggest best
receiver is an onkyo tx sr706 with it feeding two front in wall , two ceiling two rear in wall with center woofer only thing i can change out easy. i want to add to standing towers under the polk wall speakers and sub... do i need a new receiver or additional whatever you call it to feed additional speakers..
guess asking the best way to upgrade without ending up with used equipment i love the receiver and the sound is great now, but i see two klipsch towers i want to add to the front without unhooking my polk wall fronts...
thanks in advance all i would of looked in search but i dont know what terminology to use
