Hi All, I have a Onkyo HTIB some time back. It still is working. The receiver is the Onkyo HT-R510... It's a 6.1 system with the following specs: 6-channel amplifier 100 watts per channel min. RMS at 8Ω, 2 channels driven from 20 Hz to 20 kHz with no more than 0.08% total harmonic distortion The Center Channel is the Onkyo SKC-200C. I am moving into a new home and am looking to see if I need to upgrade my speakers (budget to mid price range). I am going to upgrade my Receiver purely cause of HDMI connections. I have read that the center channel speaker is the most important followed by the L/R Fronts and Sub. I am not sure how mine compares to what is out there now (in the budget to mid range price wise). I was looking at the Polk Audio C2 for center channel...but not sure if I should save the money instead for something else. P.S.: I am going to measure the new living room and run cables and stuff soon.
