Procedure

Note that it is important to keep the subwoofers tightly packed to avoid polar anomolies caused by spacing.

Procedure

The normal procedure is to measure the angle from the top of the vertical subwoofer stack to the highest/most distant seats (using an inclinometer) and to calculate the required delay increment with the formula shown.

Example

We wish to project bass/mid-bass punch to stadium balcony seats 30º higher than the top of our WLX stacks.

The WLXs are 490mm wide giving a centre-to-centre spacing of 0.49m.

This means that our delay increment (in ms)

=

tan 30º x 0.49 x 1000

 

 

340

 

= 0.577 x 0.49 x 2.94

 

=

0.83mS or 830uS.
