Here's a crude schematic of the XO I've been using it for past year, rather satisfied with it so far. Arrived at this design after much trial and error; a great deal more error. The cabs themselves received much TLC before work began on the XOs. Cabs heavily braced; Horns each damped with 10lbs of non-drying modeling clay. Cabs sport 10in wings; horns also have side and top wings.
The throat and interior of the horns were buffed with sandpaper to remove surface imperfections caused by welding splatter.
I used decent, but not exotic components in the XO, foil inductors, metal film resisters, and surplus PIO caps bypassed with smaller values.
The amp used is a Simaudio Moon i-5080, Jolida CD-100, and an early Oracle Delphi with a Zeta arm and Koetsu Blackline Gold cartridge
Just about everything I?ve learned and applied to my Altecs was acquired from members of this site, so do appreciate any additional insight on my design.
Thank you.
Cheers
