"overkill" is much better than "clipping" at these power levels. I'm a big fan of overkill for the life of my speakers.
I want to start off by saying 'Thank you' to everyone who contributed to this thread.
I have had a 7.1 Energy Veritas system for 8 or 9 years now with the 2.4 acting as the L and R. I have had a Denon, Outlaw and Emotiva amps try and power the speakers. I have read a lot of reviews about how these speakers were true full range and there wasn't any need for a subwoofer. I always laughed at those comments because I felt that the bass response was weak.
My configuration was using a Outlaw 770 to power the center and 4 surrounds with a Emotiva XPA-3 powering the two 2.4s.
Reading through what other people had done I decided to try a Pro Amp and picked up a QSC GX5 this weekend. It arrived today and I just got done hooking it up. . . Add me to the list of 'New amp is making me grin from ear to ear'. I started off by just changing out one channel to do a side by side A/B comparison of the two while running. Right off the bat I could tell that the QSC sounded clearing and I heard enough bass I thought I left one of my subs on. To my surprise it was the 2.4 powered by the QSC. After 9 years the 3 6.5 woofers were actually moving actively! The front port of the 2.4 powered by the QSC had decent air movement through it, the 2.4 still powered by the Emotiva had just a hint of a little air movement. I then hooked up both of the 2.4s to the QSC and turned up the volume and if had no problem powering them above and beyond what I have ever been able to do previously.
I do admit that the stock fan on the QSC is very noisy. I am surprised that they use such a noisy fan when the computer market has really created a market for quality high CFM low noise fans. I have a closed equipment closet but even that isn't enough to block the fan noise from the QSC. After letting it break in I will resolve this by switching out the stock fan.
i am surprised about the Emotiva amp not doing as good - i never heard them so i cant say - but i hear all good things about Emotiva amps - i cant imagine it not giving you the output you expected - could it have been something wrong with it ?
