A while ago, I purchased a pair of Altec speakers. They are designed to have an external crossover.
Specs:
Woofer: 411-8A
Horn: 511B
Driver: 802D
All the components seem to be working fine. Spec sheet for the 802D driver calls for crossover at 500Hz with N-500E crossover network. Could not find the spec sheet for the N-500E, not I could find them on the web. However, there are a couple of N-500D crossover networks on sale on Ebay.
Anyone know the difference between N-500E and N-500D?
