Bass and Kick Compression - How far down are you crushing?

[MoonUnit]

Was Reading through the online book "How To Make A Noise" that someone posted on DSF and came upon this:

Modern music is highly compressed—if you want your music to stand out, then you will probably compress your music too. If one area of the frequency spectrum is dominant this will mean that the compressors will be disproportionately affected by that part of the spectrum making the rest of the mix comparatively quieter. This is the case even if you’re using a multi-band compressor where you will still have one band (or more likely several bands) dominated by one sound. The net effect will be to take energy out of your mix and make it sound comparatively quieter.

unless you know basic compression stay away from multiband compression
unless you know how to do a good mixdown, stay away from multiband compression
