Betsy / Eminence Alpha 15 A MK II

Update: After some critical listening I decided that the treble was not to my full satisfaction. Check out my later post of the MK III version, where I have added a tweeter. 



  
  

Here are the drawings of the construction:

    1. I’m sure one can. This version was crossed at @ 200Hz high pass 6 dB Butterworth; Low Pass 48 dB Linkwitz-Riley.

      I was not entirely happy with the treble performance. Betsy is laking a bit in the higher registers.

      I have since added a dipole tweeter, made it a three way design and went with 18dB Butterworth at 200 Hz and 2000 Hz. I will post pictures tomorrow.
