I have an opportunity to buy a Kustom 3x15 cab with original JBL's. The seller will not allow me to open the cab but I did test it and it sounded great. My question is:
What is the impedance of each speaker and what is the total impedance of the cab?
Thanks in advance!

Each speaker if original is 16 ohms.
All three are wired in parallel so with a ohm meter hooked up to a short length cable at the jack you should read less then 6 .5 ohms like 5.3.
If you get a telescoping mechanics mirror you can stick it in one port and put a small flashlight in the othe port and see for sure what's in there.
It could be a bass cab and loaded with D140 JBLs, or it could be a guitar cab and loaded with D130 drivers.

Yes, it's a guitar cab then with the 130s.
The straight/ vertical front is a early 250 type cab.
There was a point in late 1971 or early 72 where the standard black tuck & roll being used had a much courser texture to it then previous and I believe this is also when the grill cloth with the silver strands in it started to be used.
