We manufactured your speaker the 37th week of 1989. It was a custom designed OEM speaker that we manufactured to one of our customer's specifications. It is a 16 ohm speaker with a 1.75" voice coil and a 30 oz ceramic magnet. We do not rate OEM designs (that is left up to the customer to test and rate their cabinet or amp), but a conservative thermal power rating based on the voice coil diameter would be about 50 watts. Here are the T/S parameters:



05-RE OHMS 12.75 13-FS HZ 104.54

06-LE MH 1.10 14-MMS GMS 24.40

08-QE 1.200 16-RMS NS/M 1.7426

09-QT 1.060 17-VAS LTRS 36.00

10-XMAX MM .90 18-SD SCM 519.45
