Unlike my previous post about the L-Acoustics preset guide, d&b guide’s its users to perform subwoofer alignment using their ArrayCalc simulation software. I have heard from more than one colleague that they stopped using their audio analyzer after they started using d&b ArrayCalc. With such claims of accuracy I was really looking forward to comparing the results from SubAligner.
Y7P + Y-SUB
At matched level with CUT engaged the center of the crossover region is at 138Hz.

Here’s a prediction at 125Hz.

The result from SubAligner is in good agreement. The minimum delay in ArrayCalc is 0.3ms. 1.35 + 0.3 = 1.7ms.


Here’s a link to this alignment in SubAligner.
J12 + J-SUB
With the sub level offset +6dB from the low-mids and CUT engaged, the center of the crossover region is at 139Hz.

And now the results from SubAligner.


Here’s a direct link to this alignment in SubAligner.
E8 + B6-SUB
At matched level with CUT engaged the center of the crossover region is at 144Hz.

And the SubAligner results.

Have you done any subwoofer alignment with ArrayCalc and then verified it in the field? What were your results?
Hi Nathan,
What’s going on with the d&b speakers from 400-700hz? Intentional wide bell cuts about 3db, part of their sound signature? Or this is room abnormalities. The subs have a steep low cut filter, 48db/oct LR? Thanks.
Hi Tom! This is mostly like cancellation from a reflection. There a bunch more d&b speakers on Tracebook that do not exhibit this problem: https://trace-book.org/measurement/db-audiotechnik-y7p-y7p
