Many thanks for this reply Bob,
It seems that you may be right and that the 'music' mode introduces an 'artificial' boost; not the 'movie' mode. Please see below...

Why not just do a simple frequency response check of your sub and find out what the switch does? |
...and thanks Bruce,
I kinda did -following Darren's suggestion I used a relatively bass heavy stereo CD track (that would obviously bring the xover into play etc), audibly
AND SPL meter testing the reaction to the different 'modes'. After about 15 minutes, it was clear that the 'music' mode sounded a bit 'boomier' and the SPL reading seems to back-up my conclusion as it was reading about 3db higher with 'music' mode as opposed to 'movie' mode.
So do you guys think I'd be right to conclude that the 'music' mode introduces the artificial boost and that the movie mode would offer the max low frequency/flatest output
My sincere thanks for your responses so far guys, its been a big help.
All the best,
DC
