Subject: X arm ALS post-beatbox makeover 

I ran a series of diagnostics on the X arm ALS to look at how the beatbox behaves after the makeover.

Diagnostic tests run:
1. X arm ALS in-loop spectrum
2. X arm ALS out-of loop spectrum
3. X ALS scan of the X arm cavity

The noise suppression looks better after the makeover at the lower frequencies. To suppress the noise at high frequencies, we would have to add more whitening filters.
