I'm probably not setting something in my Sony DA4ES, but I'm stumped nevertheless, so here goes: I'm running JBL S38s up front; I understand that when you set the front speakers to "small" and set an appropriate xover point (say 100 Hz), you shouldn't be getting as much bass out of them than you would if you set the fronts to "large" (and setting sub to "no"). However, on my DA4ES when I set the S38 fronts to large and sub to no, there is no discernable difference in bass output between small and large (I tested with a bass-heavy track and tried all sound settings--multi-channel with/without decoding, 2-channel stereo, EQ setting on receiver disabled/flat). Granted the following is apples and oranges, but when I perform the same test (using the same S38s) on my Pioneer VSX-D511, there is a noticeable increase in bass output when I change the front speaker setting from small to large. Anyone--especially fellow DA4ES owners--know what I'm doing wrong, do I have a defective receiver, or is it just the nature of the DA4ES? I was quite disappointed on my findings, especially considering the receiver in question, but I'm hoping that it's just something I overlooked. Thanks!
