Seeking advice on which speakers to buy to grow my HT from a 5.0 to a 5.2.4 configuration over the next year or so. Currently using Klipsch RF-35s as Fronts, RC-35 as Center, and SS-5s as Side Surrounds driven by a Denon X3600H in a 16' x 24' room with an 8' ceiling. The MLP is a couch against the back wall roughly 11' from the front speakers and the HT is used 50% for music and 50% for movies/tv. Call me lazy but, I have no desire to install ceiling speakers, wife wants to keep the furniture where it is, and neither one of us want a system that shakes dust from the crevices. However, the bug has hit and I want to add dolby enabled speakers and a couple subwoofers over time without spending an arm and a leg and/or getting on the wrong side off my better half. Thanks in advance for any recommended model numbers, purchasing sequences, and or critique's of exiting equipment.
