Before I go and see what the dealer thinks I was wondering if anyone else feels the same?
In the 1990s A hobby of mine was giving talks on installing & setting up sound systems for "Sound Off's" basically competitions. I was never into getting it as loud as possible (usually mono) more quality & accuracy of sound in stereo my base line was my domestic set up turntable; valve amps & Quad electrostatic speakers :,
The aim then was to get the middle position as the centre of the sound field.
I still have some of the the CD's used to judge: I have had my Q5 for 2 weeks now, I have noticed that after giving the B&O a real workout with my sons I pad music mp3's at 320kbps and Test CD's (remarkably there is bass output from the 6.5 " sub woofer in the spare wheel below 20hz ) the balance has changed to this centre oriented mode,from my previous adjustments. I have also found that the only place that is phase perfect is with balance and fade set to centre.Though the stereo image moves as would be expected with the addition of passengers.
I do not have access to a VAG-COM lead so can't get to infernal gubbins (VCDS?). I understand that a lot of the B&O wiring is via fiber optic cable, removing any chance of phase adjustment. I also understand that the set up is different on the B&O depending on seat material
ie leather or cloth
Back in the day I had (still have) a 7 band parametric graphic equaliser with discrete 5 channels & one 4" speaker wired out of phase compared to the other 25 speakers and 7 amp channels to get things perfect, even allowing for number of passengers & open windows.
On the way back from Dorset last night I floated the idea of a additional 6.5" sub-woofer in what is known as a 1/4 wave folded horn enclosure to add to the bass, SHEMBO ambivalent, son supportive.
