Description

One Unit IPC Model LU-1122 Crossover Network.
Measures 12" x 7 1/2" x 5 1/2".  Net Weight 15.5 lbs/7.2kg.
This is a very very old crossover network made by IPC Model LU-1122.
So old a google search yielded nothing!  It is a crossover network for a very old Lansing Speaker System.
I have no idea what it does or where or how to hook it up.  Just found it at an old radio show.
The big transformer has a number P-3257 printed on it.
This unit will be sold "as is" with No warranty of any kind.
Thank You and Good Luck : ) : )
