Item specifics




woofers, mid/bass drivers


40-1011A, 40-1011


Radio Shack, Realistic

Offered for your consideration is a matched pair of Radio Shack 6½” inch woofers, model no. 40-1011A. These poly-coned long-throw woofers were sold for over 15 years, interchangeably under their Realistic brand, and this pair was purchased around 1998-99. Please take a look at the large photos and catalogs specs scan I’ve provided for your review to decide if these nice quality drivers are correct for your needs.

As you can see, these woofers are excellent condition. The sturdy poly cones are in flawless shape and the voice coil dustcaps and hard paper flange gaskets are perfect as well. Plus, the steel baskets have an attractive black enamel finish which also protects them from oxidation. And, the surrounds are durable modern polyether foam and are still very springy and pliable with no wear or decay noted. They’ll need to be replaced at some point, but that may be quite a few years from now. Lastly, the +/- terminals measure the industry-standard .205”, are marked for polarity, and have never been soldered on the spades. This is a well-executed, capable driver design.

They’ve been fully tested and sound terrific with nice clarity, detail, and no scratchiness or other sonic issues. With their sizeable ceramic magnet structure, the low-end output is rated at 50Hz, solid for a 6½” platform. Plus, they carry up to 6KHz and have 50W handling power, so these wide-range drivers are also fairly stout. And, I tested their DC resistance at a closely-matched 7.8 and 7.9Ω, respectively, right in line with their nominal 8 ohm driver rating. Lastly, the baskets measure 6½” across, they stand 3¼” tall, and the mounting pattern is the standard 4⅜” adjacent / 6⅛” diagonal, c-t-c.

These are a nice find if your speakers have blown or damaged 6½” mid/bass drivers, and they’re also ready for action in a two or three-way speaker-building project with the other drivers of your choice. As pictured and described, this outstanding condition pair of Radio Shack 6½” poly-cone woofers is offered at a competitive price.
