Hi Undecided5,

As long as the M40ti didn't fall over on its front baffle, it's unlikely there's any internal damage. Speakers are fairly hardy devices and can withstand a fair amount of physical abuse. Use your pink noise Dolby Digital alignment signal to ensure the tweeter and woofer are both working. Put your ear right up to the tweeter--the hiss should be smooth sounding.

Regarding your other post on alignment DVDs, the Sound&Vision Home Theater Tune-Up disc is much easier to use than the Avia disc, and less expensive as well. It has lots of excellent subwoofer/satellite calibration tests. Get it by all means, and the Radio Shack SPL meter (analog version), otherwise your settings will be all over the place. And yes, using the DVD and the meter, you should arrive at a subwoofer setting that will suit most movies and much of your music, apart from actual differences in the deep bass levels of the program sources. Those may vary quite a lot, but you can trim the sub volume when required.

Don't forget to experiment with subwoofer locations as well.

The S&V DVD also has plenty of video calibration tests to properly set up your TV monitor.
