Offered for your consideration is one (1) vintage ROLA Alnico magnet 12 inch full-range driver, USA-manufactured in 1973. As you probably know, ROLA was a notable supplier to the domestic speaker industry from the 1960’s through 1980’s. Per the EIA source/date code stamped on the basket flange rear, “2857344”, this driver was made by ROLA (285) in the 44th week of 1973.
Please have a look at my large photos and read the remaining description to decide if this outstanding ROLA speaker is correct for your needs.
This ROLA full range driver is in clean, excellent condition. The sturdy ribbed paper cone is in perfect shape and the fabric voice coil dust cap has no dents or dimples. Plus, this speaker features an ancillary or “whizzer” cone to enhance the high frequency response. Also, the surround is integral pleated paper—effectively permanent—instead of the fragile foam that was in widespread use at the time it was made. And, the galvanized steel basket is in great shape with no dents, scratches, or oxidation.
What’s more, the +/- terminals measure the standard .205” and are marked for polarity. I’ve left a length of the input wires soldered to the terminals for the new owner’s convenience in splicing-in to their system. Overall, this ROLA driver is exceptionally well-preserved.
Most importantly, it’s been fully tested and sounds great with clear, fast mid frequencies, strong bass response, and treble at the threshold of audibility. Plus, I tested its DC resistance at 7.1Ω consistent with a nominal 8 ohm driver rating. Lastly, the basket measures 12¼” diameter, it stands 6¼” tall, and the four-corner mounting holes are spaced 8⅜” adjacent / 11¾” diagonal apart, c-t-c.
So, as pictured and described, this superb ROLA 12” full-range driver is offered at a competitive price.
