BOSE 2¾" full-range driver for double cube and cube speakers, c.1990—excellent

Description

Offered for your consideration is a
BOSE
2¾ inch full-range driver
removed from their ‘direct-reflecting’ Acoustimass double cube speakers, c.1990. This is a correct original driver for the first two generations of
BOSE
cube and double cube speakers—the large, more angular or "squarish" first version (charcoal or white enclosures that may have one or two grille emblems) from the mid-to-late 1980's and the second, more rounded version (“redline”-trim in charcoal or white) made into the early 1990’s.
So, please have a look at the large photos I’ve taken and read the remaining description to decide if this superb driver is suitable for your speaker.

Although the listing is written in singular to avoid any confusion, two (2)
BOSE
cube drivers are available for purchase at time of this writing. The code on the magnet cover and/or the size of the voice coil dustcap may differ from the one photographed (
BOSE
used several companies for its speakers) but the drivers are otherwise identical. Please choose if you’d like to buy one or both in the quantity field at the top of the listing. The shipping cost will be automatically calculated by eBay checkout
.
This driver is in clean, excellent condition. The sturdy textured paper cone is flawless and so is the poly voice coil dustcap. Plus, the surround is
permanent
coated fabric, not the fragile foam typically used. And, the anodized steel basket is in perfect shape with no dings but the bell magnet cover does have some light oxidation. Lastly, I left several inches of lead wire attached to the
BOSE
-style +/- ‘spike’ terminals (positive is marked with a red stripe beneath the spade) for your convenience in retrofitting to your speaker. All-in-all, this driver is exceptionally well-preserved!
Recently tested, this
BOSE
driver sounds terrific with strong and clear output, a detailed midrange, and surprising low-end for the platform size. Plus, its DC resistance tested at 3.7-3.8Ω consistent with a nominal 4 ohm driver rating and it’s also magnetically shieldeded. Lastly, the basket measures 2¾” wide, it stands about 1¾” tall, and the mount holes are spaced 2 3/16” adjacent / 3⅛” diagonal apart, c-t-c.
So, if you have a blown or damaged driver in your first or second generation
BOSE
Acoustimass cube or double cube speaker, you’ve found the right listing—your speaker will be sounding its best again in no time!
So, as pictured and described, this superb
BOSE
2¾” driver is offered at a competitive price.
