Zenith 49CZ873 12" Wide Range Alnico Woofers ~~ $85 plus shipping ******SOLD******

These are pretty nice vintage wide-range AlNiCo woofers pulled from an old Zenith console. Photos and rough measurements are attached.

• The first measurement is a combined far and near field measurement. The impulse response shown is the far-field measurement.
• The second measurement is my best attempt at showing the off-axis response, measured far-field at very roughly 15 and 45 degrees.
• The last two measurements are near and far field distortion measurements.

EJ Jordan JX92S Full Range Drivers ~~$275

Details about these can be found online. The drivers are used, and have some flaws in the cones all of which are aesthetic. I can measure nor hear any difference between the drivers, despite their different flaws. They sound awesome.

I have inspected them very, very closely and put arrows on the photos pointing out everything I found.

• The first photo with arrows shows some small dents on the first driver.
• The second shows some small dents on the second driver.
• The third photo shows small bulges in the cone, which were the result of the process by which the tinsel leads were glued to the cones. This is a factory defect.
• the last photo shows some small specs of dirt on one cone that I was unable to remove.

Please ask questions if you have any.

Tang Band W8-1808 Full Range Drivers ~~$275

These are in great shape. Note: the stickers on the bottom of the drivers were peeling, and one speaker has an imperfect cone/whizzer. I wouldn't call the marks creases, as they do not show on the reverse side of either the cone or the whizzer. I'm not sure exactly how the flaws were made, but again, they are entirely aesthetic. The drivers work flawlessly and sound great.
