Help! Need help identifying speaker in Sunn 2 x 15 cabinet
« on: September 20, 2004, 12:03:08 pm »
I've got what looks to be late 60s Sunn 2 x 15 cabinet.  It has two 15" speakers with the following identifying numbers 5815113 and then below this 137-6811.  There is no brand name anywhere.  Can anybody give me information on the make and quality of these speakers?  Also, date the cabinet better?  Thanks!

The 137 identifies the manufacturer as CTS. 6811 means they were made the 11th week of 1968. I believe 5815113 is the CTS part number. Sunn used these as a low cost alternative to JBL's. Nothing special about them but if they still work after 36 years, they couldn't have been that bad.
