I was wondering about that. I thought since the M40's were in a larger cabinet they might have added a crossover. I just looked at the Sound Stage graph for the M3ti's and they have almost the same dip as the M40 does. Maybe it's just the way the 6.5" driver is voiced. Maybe I have to live with a touch of EQ. Running from the laptop that's easy since Foobar has an EQ. Running from other sources will require putting the Behringer Ultracurve DEQ2496 back in the setup. Since I went to the amp switching arrangement that I have now that's going to be tricky to do.
