BD on a Sony BD player, exact same source (I even took my player & BD to her place).
After chatting w/Yamaha CS, as all other sounds/tests regardless of frequency are excellent I've decided to chalk it up to a fluke in her Polk MagniFi Mini that amplified a sound that isn't amplified by other...
I agree that there shouldn't be a single acoustic anomely when all other sounds appear normal.
The only other thing I can figure is the Polk MagniFi Mini's basic algorithm is somehow enhancing that particular sound and my Yamaha isn't?
I also agree about not using sound fields, but I tested them...
Go easy on the noob, guys! ;)
Just picked up a Yamaha YHT-4950UBL and am *very* pleased with the sound upgrade compared with my old Sony HT-NT5 soundbar.
Everything's configured and running well, started testing sound quality with numerous DVD sound/action scenes.
Everything is excellent...
