Mixing and mastering EQ, etc.

Hi all,
In modern dance music its common to High cut anything but the kick at 30-120Hz and also do some eq cut in the ranges 400-525hz.
Does this go for pure ambient/drone sound too? Offcourse it would be dumb not to remove unneeded/unhearable/playable frequencies giving more headroom for rest of the mix.
Also mono is often used on lows too, due to clubspeakers or sub basses in general are mono.

What are your thoughts and/or how are you views on this?
I know there is no template for this, but your views would be nice.

Btw. just bought Izotope Ozone 6, got a little tired of mastering using Lives plugins. Also Ishould get Ozone 7 free when its released start of november. :-)
I tend to master standalone as it gives, for me, a good workflow out of the ableton interface, which is great creating and mixing.

IMO there's no hard rules to mastering, just a lot of best practices. If you have trustworthy monitors, your ears will tell you if something is wrong. Working with a spectrum analyzer is essential.

From my experience, yes, you'll want to EQ cut strong overpowering frequencies in a drone. Using a multiband compressor to tame peaks in narrow frequencies along with EQ or just on its own works well.

Narrowing the stereo field for very low end stuff is generally a good idea. I wouldn't mix it down to mono though.
