Is comb filtering that big a deal? This affect is usually present when you have a wide baffle and lots of drivers. This seems to frighten audiophiles. However when you have this situation, you get more spl and less distortion, for me that is an ok trade-off.

It can be a big deal if it's "bad". 
You can create a badly comb-filtered file in Audacity- Open a file, zoom way-in and move it to the right by 10-20 milliseconds (to create a delay). (This is what happens when there's a delay caused by one speaker being closer to your ear than another, except 10 milliseconds is about 10-feet.)
Now import the same file again into the same project (but don't delay it).
Use the Amplify effect at -6dB so mixed tracks don't clip. Now you can play or export the audio and you'll hear the "phasing" (comb filtering).
