thanks Schu,
I think you are onto something.... the lowest x-over point for these subs is 50HZ. i'm pretty sure my floorstanding thiels go lower, but they are just sitting on carpet & don't seem to produce the really low freq's this way.i've been trying to figure out if there's cancellation somewhere, but to my ears the entire presentation is spot on.
i don't have a way to measure it, but do know a guy with an RTA & mics if worse comes to worse. maybe i should just get a rat shack db meter & download a test CD?
well, since i can't lower the x-over frequency more, i won't lose sleep over it.
In summation, changing the Phase changes everything. More deep bass at 0 degrees but way more 3-D wildness at 180 degrees. At 0 degrees, the subs shake the floor a bit. At 180 degrees the cabinets barely vibe even though the driver acts the same, same exceursion.
to some this may seem like a preference issue, but its not.
My room is treated, and to my surprise the budget acoustic kit does not seem to be overpowered by the subs whatsoever. i don't listen at high spl's though, which is probably the real test.
neither sub is turned up more than 30% of volume. With the phase in either position, turning up past that point sounds bad, doesn't integrate as well.
RBG, please chime in if you are available...
