Sub delay kicking in

[ianmarrey]

I have a Marantz 7300 with KEF 2005 (1st edition). All is fine except for one little but annoying gripe.

I have Sky+ and when first switching to a music channel there is a noticeable delay in the subwoofer kicking in, about 2 seconds.

I have messed around with various crossover frequencies with absolutely no effect. I do not use the auto switch so the sub is always on.

Any ideas?
