SAM, high pass, and subwoofers

[watchnerd]

You can turn it on and off with the remote control if you set it up in the configuration so you can test it with your own ears. You can also adjust the boost between 0 and 100%. On 0% you still get the advantage of the timing adjustment between the woofer and the rest of the drivers.

What does the timing adjustment do?

I would have thought the manufacturer's crossover would already be dealing with tweeter / woofer time alignment.
