I am finding the built in sub a little boomy. Whilst I love base, I get all the bass I need (When watching movies) from my REL. But when I watch 'normal' TV, ie Eastenders, I just use the TVs speakers in Stereo... But the Bass is a litle too overpowering. For example, in Eastenders, there is often music in the background.. On the Philips, the bass line/thump of this music can be clearly heard. I have tried turning down the bass, and whilst this helps, it makes the normal (i.e not sub-base) disappear too making the sound very flat. I would like to leave the bass up a bit, but disable the sub-woofer.. Can this be done.. Perhaps in the service menus??
