Re: @ AJ MacLeod
The issue is, there are armchair engineers out there, then there are proper degree qualified electronic engineers that have spent three or four years studying this subject (along with a load of other stuff) at university, that understand the concepts of: frequency response, phase response, impulse response, Fourier analysis. The author is the latter, quite evidently so. Some people on this forum are the former, clearly so.
That's not a criticism of the former, but they need to know which category in which they reside, and be able to recognise which posters on this forum fall into the latter category.
Knowing a little about frequency response and 3db points and 6db per octave cut-offs doesn't make you a qualified electronics engineer.
