I found that adjusting the sub-woofer setting does not seem to make any noticable difference to the sound, although it is clear that the thing is working.
I think the system is very well tuned and the adjustment provided makes subtle changes rather than big ones which is in line with the quality of the system. The type of low end frequencies put out by the Sub are much more difficult to detect and some of them are 'felt' rather than heard. Try operning the boot while it is playing and listen to the sound it produces, it seems very muffled, however the impact it has on the overall sound inside the car is significant.
Thanks iceman. When I took it to the Jaguar garage, we did in fact open the boot and also the cover for the spare wheel - the SW is underneath the spare wheel. It was at this point we noticed it wasn't doing anything. The technician then noticed there was a loose connection which was sorted in seconds.
update: I put my head in the boot with a CD playing and the subwoofer seems to be working (and I can see a connector that is clealry plugged in). With my head in the boot I can also notice a difference between the min and max subwoofer settings but it's a fairly subtle and is almost unnoticeable from the driver's seat. Can others hear a difference? (perhaps I have cloth ears!)
Re-reading this thread I think my findings are in line with Iceman's.
Despite this, overall I find the sound to be excellent - today I was in the car myself so cranked the volume up and it seemed beautifully balanced and well judged - much like the rest of the car!
jagseven. Patience yields excellent results with the B&W system.
I found mine went through phases. This is perfectly normal with high end components, particularly the kevlar drive units. I experienced a boomy phase where bass was too pronounced, a shrieky phase where the high end was over the top.
I can't remember how long it took but one day it was just right.
Stick with digital sources, DAB, I-pod, USB or preferably CD and it'll soon come good.
I don't know your musical tastes, but if you want to give the sound system a workout, try Massive Attack, Faithless, Linkin Park or Prodigy. All are well produced and will get the system singing.
