d&b audiotechnik ArrayCalc vs SubAligner

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.

Here’s a direct link to this alignment in SubAligner.

Have you done any subwoofer alignment with ArrayCalc and then verified it in the field? What were your results?
