Rusty,
- As RobH pointed out ( as well as subwoof ) / wire the 3 drivers according to what you see in that schematic .
- As to reconciling the wiring in the posted schematic, to what you and Oldmics have observed / here's what you both need to know ;
"Polarity Checkers are very unreliable devices when used on ( passive or electronic ) "all-pass" networks ( & thats what that Urei network is ) .
- ie; They can give a false reading .
- The delay derived from an all-pass network is frequency dependent ( so all the phase changes go through multiple 360 deg. rotations ) .
- This makes "polarity" a moving target over the operating range of the transducer .
- One typically doesn't encounter this when dialing in a delay on a digital speaker management system ( such as Oldmics typically uses ) .
- One always encounters this phenomenon when using older analog crossovers that offer a simple "delay" adjustment on only the woofer section ( such as I continue to use
) .
