terminology

Planar Speaker Asylum

Welcome! Need support, you got it. Or share your ideas and experiences.

Please make sure me and others are using these terms correctly.

'crossover frequency' is where the high pass and low pass response curves cross on a graph.
For my MG1.6, that would be 600hz. The elecrical response appears to be 3db or more 'down', while acoustic response would…or SHOULD sum to flat. That would be BOTH drivers 'active' in the crossover region.

The term I DO NOT see referenced is what I'll call, from my semiconductor days, the 'KNEE'.
This is where the curve begins its downward trend.

So, again for the 1.6, that would be somewhere below 600 for the LP and above for the HP.
Wouldn't THOSE be the frequencies for which I'd design a crossover? Are those frequencies knowable or subject to some degree of experiment? What would I do if I want to duplicate the Magnepan transfer function?
Or if I choose a crossover frequency….do I choose 600hz for BOTH the LP and the HP?

Right now, I'm not concerned…overmuch, with the SLOPE of the curve, from 6db/octave UP, but rather just the idea behind some of the terms.
Too much is never enough
