Thanks for that info.

I looked a bit on the Altec Heritage site and didn't see a Zobel network for the HF horn.

I was not sure if I should use one or not, but the Dayton driver has a weird impedance graph compared to most I have studied.

The horn is crossing over first order at 1.8KHz.

I was looking at some compensation networks because the high Hz's start to roll off at about 10KHz as measured at my listening position.

Tom Brennan posted one that has a cap and resistor in parallel across the top of one of 2 series fixed resistors from + to - on the horn.
