I only heard it once for a few hours. I was impressed. My friend was very good technically with speaker design including things like dispersion and low distortion. By the way I was surprised when he told me how high the crossover was.

100 hz is what I use and after experimenting for 5 years that is the highest anyone should use.

  My friend was concerned with taking as much load as possible off the Quads so he could push the overall system harder and handle large transients.

    and I should have added that the slopes should always be minimal i.e. first order and 6 db/octave for the best sound. My next experiment I may try a series crossover instead of parallel. When I used it years ago with dynamic drivers it was clearly superior
    
    If you want greater volume output use 2 Quads for each channel. It's vicious circle

      Having the equivalent of four per channel with U790s obviates the need for a sub. ;)

        Even if stacked four high subs will be required if one wishes to have the bottom octave.
        
        Sure the mid, upper bass will be as outrageous as the SL but it still won't do the bottom octave.
        
        I've heard them stacked 3 high. Oh yeah they have as much boogey, slam, scale as the U745/90 but......
