Hi Adrian,
Yes - I know. However, as I posted previously, moving around the room produces very little difference in perceived bass and for there to be a pronounced bass trough somewhere in the room you would expect a peak elsewhere and I can't find one. Also, my new speakers are sounding distinctly more bassy in the same position.
Well, I hear the bass just fine in my other systems so Occam's razor suggests my ears are not the problem :-)
Cheers,
Simon.
