Thanks Timo, forgive my poor english.

I hope that, being a speaker essentially a minimum phase device, I will be able to achieve the desired result by choosing the crossover points in the drivers' linear band (and where the frequency response covers a wide angle) and to fix the remaining response irregularities using the Linea Research parametric equalizer.

Finally i'll try to reformulate my last question:

Using LIR's crossover topology can i obtain a betters drivers integration (less destructive interference) over a wide listening area?

Regards,
Roland

You need to verify over a large area so onax-ofax horizontal and try to minimize the problems in the vertical plane.

If the driver used in your design is a coaxial one try to get a clean alignment on both planes onax-ofax horizontal-vertical.

With a 3 or 4 way design you'll run in to a multiple of the challenges described above.

A small post on the difference between Time alignment and Phase alignment. Enjoy ;-)

By the way No subs used in this screen capture and the main system's phase respons (a Fulcrum Acoustic FA22ac) has been modified via 2 Allpass filters for the purpose of this screen capture......
