Hi Romy,
Always nice to correspond with you, thanks for your comments.
I used the term 'sophisticated' literally: so - phis - ti - cat - ed Adjective: 1. ( of a machine, system, or technique ) Developed to a high degree of complexity.
As do you, I prefer multi-way horns so most DEQX based systems are not interesting to me but most of them are definitely sophisticated.
Passive speakers level crossovers are not as good as line level passive... I think you explained why rather well in previous posts.
We disagree, obviously on active crossovers but I am not alone in my thinking - and you know the theoretical ( at least ) advantages of active filtering very well.
Attenuate: at - ten - u - ate; Verb; Reduce the amplitude of ( a signal, electric current or other oscillation ).
I don't understand when you say active crossovers don't attenuate. Mine does. Very well too, I can trim channels to match each other perfectly. And DEQX volume control is 'analog' = step ladder resistors.
I am not qualified to defend active and or digital crossovers on technical grounds... but they work. Well. Very well.
Here are some links for you:
