    A lot of variables. The room, how you place the speakers (boundary reinforcement/room gain), how close you sit, how loud you normally listen, and our hearing curves. I do rely on the equal loudness curves somewhat, which tell me it's probably smarter to dial the top down a bit when balancing a network. 

    Ultimately it would be great to be able to adjust, attenuate, with a dial, the mid and tweeter to account for the variables.  How possible is it to work this into the crossover?

    Tap 2 with one 2.5uF = -9dB (101dB)/1000Hz

    Tap 2 with two 2.5uF parallel= -9dB (101dB)/500Hz

    Tap 1 with one 2.5uF = -12dB (98dB)/500Hz

    Tap 1 with two 2.5uF parallel= -12dB (98dB)/250Hz

     

    To keep the crossover at "500Hz", you can either use Tap 2 with 5uF (two 2.5uF in parallel), or Tap 1 with a 2.5uF

    Thanks for the clarification.  I have mine set to Tap 2 with two 2.5uF parallel which I changed from the original setting from Crites, Tap 1 with one 2.5uF.  I find it sounding balanced now.  The Mid driver sounded too low before.  Everyone has different preferences for sure...

    The first sentence makes sense. This is the common complaint I get from folks who reach out to me. The next sentence doesn't make sense, because moving the midrange to Tap 2 would make the midrange louder. IOWs, I'm pretty sure they ship using Tap 2 (-9, using two 2.5uF caps in parallel), with an option to move to Tap 1 (-12dB, using a single 2.5uF). 

     

    When I build them for people, I just use Tap 1. On that horn, the D405 is a 110dB driver. On Tap 2, it's at 101dB, which most will find too forward. I also go 12dB/octave on the de120.

    Please fill in the blanks:

    D405 110dB

    Tap 2 with one 2.5uF = 

    Tap 2 with two 2.5uF parallel= 

    Tap 1 with one 2.5uF = 

    Tap 1 with two 2.5uF parallel= 

    Thank you🙂.

    TIP: Did you try adjusting the crossover output for the mid driver:
    From Crites: "Remove the red string sleeving from the two red wires on the right side of this picture and connect those two wires together. Then, remove the connection indicated by the red arrow and plug it back into tap #2."
