    Mic in the sweet spot. I don't listen at 1 meter and it is really too close for proper integration of the various components.

    Then you pose the delemma as to what is preferable..., the smoothest frequency response, or the best time alignment. But let me say that using my current technique, I've never heard speakers that...

    Not so..., or at least the way I do it.

    I use the RTA with the mic set at the sweet spot and simply move the mid-cabinet/Heil back and forth until I get the smoothest transition in the crossover...

    I'm thinking that this may be the better slope. You loose as much at the top end reducing fatigue, while retaining the detail through the upper midrange.

    The electronic crossover for my Super Big Reds is dead on 1,500Hz with (IIRC) 2nd order slopes on both sides. The Utah is crossed over at ~100Hz with a 1st order slope.

    There is a way to qualitatively judge the "liveness" of a room and really determine what it is doing to the sound. You make a YouTube video in the sweet spot and compare that to the original. For...

    I had thought of that sort of thing but feel that it may interfere with the front and rear surround channels and/or block the projector to be truly effective.

    The ceiling is ~465 sq ft. Even something this simple would run ~$1,250 just in materials, not including the labor to install. And we would probably want something nicer (=>$$$).

    If you put a resistor BEFORE the first element of a 2nd+ order crossover, you reduce the volume but you don't change the slope. I actually demonstrated this on the other forum.

    Room is 26 feet across and speaker centers are at 7.5 feet so (26 - 7.5)/2 = 9.25 feet. Room is symetrical.

    Cabinets are up against the front wall and are 30" deep.

    I don't have the capability. My recordings are done with a Nikon D750 DSLR taken at the approximate sweet spot. Obviously the stereo mics in the camera don't allow for much separation.

    Who says that JBL never got into time alignment? Isn't that partially the concept of the 4430? Doesn't the 2425 line up with the 2235?
