In the standard Slick EQ, the HPF is 18db/octave. What is the thinking behind why you chose this slope as opposed to the more common 12 or 24db/octave filters?

I guess it's because NOVA already has those 2.

Surely it's not as simple as that..?

It sounds good in most cases, and is very effective at cutting lows.

Lol, looks like I was overthinking it. I was expecting a Ninja Master-ing answer.

18dB per octave is a nice compromise (between attenuation, phase anomalies, and affecting the audible range) for inaudible HPFing. Most mastering HPFs are 12 or 18 for this reason. Can also choose with or without the slight "head bump". It sounds good.

In Slick EQ M you have the option of 6,12,18 or 24, and the 18 mode has the least head bump and therefore is the most neutral sounding.

18dB/octave HPFs have been used the most in the best sounding classic consoles. You have to wonder why?
