Sunn Model 2

[box81566]

Could someone help me out, I just bought a Sunn Model 2, I would like to know when these were made and how to use them.  They have two jacks in the back.

could I play my guitar through them?
Thank you

Hello:
 The model 2 speaker was being made during my tenure at Sunn. I believe it was mostly in the 70's. It had a simple capacitor x-over with parrallel jacks on the input panel. I will try to find more info however you will find them listed in the 79 product brochure.

Here's some interesting info about the Model 2.  The interior volume NOT including interference from the speakers or the port tube is 1.94 Ft^3.  The port is 2.875" I.D. and 3.5" in length.  Looks like the tuning of the box is ~41.4 Hz before putting the drivers inside it.  This info could be useful if you were looking for other drivers to stick in that box.  Methinks the stock ones are a little anemic.  FYI!
