jinhan, thanks for doing what I should have been smart enough to do to begin with. I had to wade through stuff to get to the point I could post everything to begin with. The tenor of that thread has denigrated a bit overnight, but I also noted that there have been 10,900 views. Hopefully someone came away with something positive.

As suggested, the 5db boost was a curve ball cleverly done by Craig. The difference it made was clearly noticeable. Made a case for understanding calibration, sub placement, room treatment, etc. can significantly affect LFE.

The coolest part of the day was knowing the Craig owns a multitude of subs (7-8-9 when I did a quick count all over the house when we were all done) and trying to guess which 4 we were listening to. THEN it turns out that we were listening to 2 subs for 4 places. And the same sub sounded different for each of its tests.

EP 500 owners are undoubtedly happy bass people!
