The QSC waveguide is pretty close to the H290C in its acoustic properties; Even the acoustic center is pretty close. So the crossover is close too. I am taking this inferrence from the measurements made by Skywave Rider a couple years back. But the waveguides are different, so I cannnot guarantee performance. All I can say is mount both the waveguide and the midwoofer on the same baffle and keep the center-to-center spacing as close as possible for best results.
