| I have been working on a race track, and have noise spill from the speakers to the surrounding.
i use EASE to model to an industrial noise software package, for legal reasons.
when i close the model, and use probe the results are the same.
In order to have some reduction in the spill , i want to use a dipole set-up en flip the polarity of one speaker on cluster of two.
how can this be done, it would save some time, as to make a test-setup and measure... The site has over 50 speakers...
[i]I had a closer look on control of low frequencies from a reply of jim mobley on july 2009, but i need a clue on the flipped polarity...[/i] |

| Hello esonic!
Try looking within the Loudspeaker Properties options. Under the 'Phase' tab, there is a box marked 'Invert Polarity'.
Is this what you are after?
Regards |
