GEFCO heavy magnet 4" mid/bass woofer with rubber surround, US-made 1996—perfect

Description

Offered for your consideration is one (1)
GEFCO
model MR-4
4 inch midbass woofer
, USA-made in 1996. GEFCO, located in north suburban Chicago, was a notable supplier to the domestic speaker industry with much of their 1960’s to 1980’s production going to FISHER. So much, in fact, that a few popular reference lists incorrectly show GEFCO’s 1056 EIA code as belonging to FISHER. Per the EIA source/date code on the magnet cover, “1056 9601”, this driver was made by GEFCO in the 1st week of 1996.
So, please have a look at the large photos and read the remaining description to decide if this capable mid/bass driver is correct for your needs.
This driver is in clean, excellent overall condition. The sturdy poly (perhaps graphite) cone is flawless and so is the voice coil dustcap. Also, the surround is
permanent
rubber instead of the fragile foam that was still in widespread use at the time. And, the black-anodized steel basket is in great shape with no dents or oxidation on the large magnet structure. Lastly, the “double-type” +/- terminals measure the standard .205”, are marked for polarity (red dot = pos), and have never been soldered on the spades. Overall, this driver looks practically new!
Most importantly, it’s been fully tested and sounds perfect with clear, detailed midrange and solid bass for the platform size. Plus, I tested its DC resistance at 3.9Ω, consistent with a 4 ohm nominal driver rating. Lastly, the basket measures 4⅛” across (5” at truncated corners), it stands roughly 2¼” tall, and the mounting holes are spaced 3⅜” adjacent / 4¾” diagonal apart, c-t-c.  This is a great find if you need this same pattern 4” driver as a replacement for your speaker.
As pictured and described, this stout GEFCO mid/bass woofer is offered at a competitive price.
