Maybe not all, but some may know that what sounds best is what matches the design
A grand old master I knew once said that each component you can remove WITHOUT drawbacks or comprosing will give improvement
He was a strong believer in 4.order ACOUSTIC rolloff
Its a common (mis)belief that less components always sounds better
Its only true if it matches the drivers and design
But sure, a simple crossover sounds good, if it works properly
Well adjusted crossovers has no or little audible effect of its own
The mistake when "hearing" a crossover is mostly based on flawed designs
From what I've done (which is not much 🙂):
- LR4 is fine. In fact it's great.
- Electrical phase alignment is a must. XO with no time delay circuit is useless sonically.
- LR4 vs LR2, I cannot hear group delay distortions.
- Trying to cover human voice 300-3khz with no xo point runs to different problems which are more significant acoustically. It sounds bad.
- For dipoles, 1.5khz - 2khz is the sweetspot for tweeter xo region.
- Passive xo are expensive, difficult to realise, and unpredictable.

Pretty much agreed. About the electrical phase alignment - are you using the time delay to compensate for acoustic center offsets? I agree that the distances between acoustic centers (to the ear) is pretty important, although I align them all physically. The axis of radiation is equally important.
I very much agree that keeping XO's out of the 300-3kHz range is difficult, and if you do, you most likely run into serious auditory degradations, wrt dipoles.
I say impossible if you want higher end speakers that more then one person can enjoy from 12 feet away 😉
Yes, using 2-stage allpass filters.
The effect is readily recognisable if one uses a switch to turn off the delay circuit. Once recognised the sound is pretty obvious and you'd know it instantly on commercial speakers.
I think physical alignment is better as it does not rotate the phase, but sometimes you'd get diffraction problems.
I just found this thread. What struck me was the part about Reaper. I thought Reaper was strictly an audio sequencer.. it can calculate crossovers too??
Reaper is a "digital audio workstation". It can do all sorts of things. Check out this post for some screenshots of how I do it...
