Asking Differently - Setting Sub Delay

[ismarketing]

Sound travels at 343 metres per second
So to compensate for the 2 metres distance, it is 2/343 which equates to 0.00582ms
Looking at the Configurator, you can change the delay of the stereo pair by 70 microsecond increments, so you can select 485 or 605 microseconds, save it and see if you can detect a difference
My sub (B&W db1) is 1/2m in front of my stereo pair and I could detect no difference
I think low frequencies are less evident than those above say 250Hz
80Hz sounds right to me.  Mine is set the same

Many thanks Chris.  Seem simple enough.  I'll give that a go this weekend.  If folks have other thoughts/comments - they are welcomed.

Baffled that it's taking Devialet a week and counting to answer a question you seemed to clear in under two minutes.
