Use phantom as sub and center?

[fgueho]

The delay is due to the DSP processing inside the Phantom. The bass is achieved by using DSP for getting a correct response, and that takes time to process. The only way of decreasing the delay would be using a faster processor inside Phantom (not an option for current ones), or disabling the DSP processing, but then you would get a lousy sound.

Or add a component that can delay the video (if you want your phantoms to be used in a home cinema setup).
Or add a component that can delay the external sound (if you want your phantom to be a subwoofer).

Problem: I don't know which component to add...
(you need to be able to modify the delay in milliseconds, because each setup is different)
