You said that the idea of using broadband diffusors is "to send different frequencies different directions to ensure they reach the listening position at different times."I disagree.
While there is some frequency-dependent variation in reflection characteristics, if anything that is an undesirable rather than desirable feature of diffusors. That's why "broadband" rather than "narrow band" diffusors are preferred. I don't think the arrival times of different frequency components of reflections is significantly altered, and I also don't think it would matter much anyway. A millisecond or two this way or that won't make a difference once you're past the early reflection time interval. The ear integrates the sound power (spectral balance) of the reverberant energy, but ignores minor arrival timing differentials.
