The Altec horns I acquired will need the Pro 4 box for the woofer. 1. Is it possible to make the 3.5X6.5X10 port a slot, instead? Say,
10WX3.5HX6.5D?
2. I have 2 sets of 1.6k Eminence crossovers, one stock for the
PSD-2002's and the other with the 10uF removed for the JBL
2226J/3677s combo. Do I have the parts I need to make an
800Hz X-over? Is there a Pi schematic for an 800 Hz X-over?
Should I just get the Altec X-over on E-bay?
3. I saw somewhere that the Altec horns were designed to be in free
air,not in the box. True? Is it okay to have it in a three-sided
box as long as it's not the same box as the woofer? I'm thinking
of the way LaScala's are built with the horn and crossover open
to the back and separate from the bass reflex boss.
