After a quick white noise test using my SPL meter and Digital Video Essentials, I set the PC-Ultra's gain/level at about 1/3 total volume, and allowed plenty of room to tweak the sub level from my Atlantic P2000 if necessary. The crossovers on my Canton Ergo speaker ensemble were all set at 80Hz. The PC-Ultra has an infinitely-variable Phase dial, handy for creating a better blend with main speakers. For my room and sub location (rear corner), I had Phase close to 180 degree. I didn't use the port blockers, not wanting to limit the sub's upper bass response; plus the "stock" sub configuration is the most common setup for potential buyers.

Final Take - For starters, I did a "Buzz and Rattle Test" using the Digital Video Essentials DVD. I detected audible volume at about 20Hz. Once diagnostics were complete, I listened to several film tracks for evaluating bass, including Star Wars: Episode I, U-571 and Blade. Bass from the PC-Ultra was consistently deep (though never boomy) with very little overhang and practically zero discernible distortion. The bombardment of depth charges during U-571 was downright jarring. The bottom end was extremely tight and detailed.
When I try to impress my father, the most I'm likely to pry from him is a resounding "Not bad." During a recent visit with the PC-Ultra connected, we watched the opening battle sequence from Master and Commander. When the last of the debris had fallen and we released our grips on the couch, all he could say was, "That was a visceral experience." Well said, Dad.
