Well, I don't drive this setup very hard. It's for video games which means I won't crank it up very high as I don't want to damage my hearing during extended gaming sessions. Some games do have more dynamic range, like maybe Metal Gear Solid 2 which I played recently. But most of the time I will keep the average volume at about 65dB and the peaks will only be ~5dB higher. I also only sit about 6ft. away from the speakers, and there are only two speakers.

Correction, it turns out the Castle Avons are 8ohms nominal.
