Here is an update. I will just lessen the LFE gain on my yamaha receiver. Tech support from QSC told me that I should not worry about the CLIP led blinking. He told me that it's just a warning and neither it causes distortion.
Here is a video of the LEDS which I took last night while playing the LFE scene from "The Haunting".

Anyways, I'll keep you posted once I start on my home theater.
