In Reply to: Response at the crossover frequency posted by Belgarchi on October 29, 2013 at 16:37:38:
With a fourth order acoustical Linkwitz XO, the drivers sum flat AND are in the same polarity at crossover frequency. Reversing the polarity of one driver will then produce a deep null, which is a pretty good test as it indicates excellent phase tracking in the correct polarity.
There will inevitably be a dip at crossover frequency in the horizontal off-axis response, and various dips and peaks as you go off-axis vertically, but this is the case with most crossover topographies. LR4 is somewhat more forgiving than most on the vertical off-axis. If you listen on the correct axis, in a reasonably damped room, there should be no problem.
