Input impedance of a WOPL 1000?

[premiumplus]

Question for Joe...what's the input impedance of a Quasi Comp WOPL 700B?
I need to know so I can calculate the capacitance needed to set the frequency roll off on the electronic crossover I'm using. It's a Dahlquist DQ-LP1.
Thanks!
Dave

Isn't input impedance frequency dependent?

Damn Scott, you don't let nothing slide do ya?? Yes, to what degree is Joe's forte...

Roughly as follows:

49000 at 10Hz
47900 at 1KHz
40100 at 10KHz
34600 at 20KHz
19900 at 100KHz
