Polk Audio 5¼" woofer for M10, R15 other speakers c.2007—two available—excellent

Offered for your consideration is a Polk Audio 5¼ inch poly cone woofer removed from my M10 speakers made c.2008. This heavy mid/bass driver was also used in the Polk R15 and T15. It’s also practically identical to the 5¼” woofer in the RTi4, the midrange in the RTi12, and likely other Polk speakers from the late 1990’s and on. So, please have a look at my large photos and read the remaining description to decide if this capable Polk mid/bass woofer is correct for your needs. *Although the listing is written in singular to avoid any confusion, two (2) Polk Audio 5¼” poly cone woofers are available at time of this writing. The first one to sell (not pictured) has only R15 stamped on the magnet cover but is otherwise identical. Please choose if you’d like to buy one or both in the quantity field at the top of the listing. Any additional shipping cost that may be needed will be added at eBay checkout. This Polk Audio woofer is in clean, excellent condition. The sturdy poly cone is flawless and the voice coil dustcap has no dents or dimples. Plus, the cone suspension is permanent rubber. In addition, the black enameled steel basket is in great shape with no dings, scratches, or oxidation, while the anodized bell cover over the heavy, double-stacked magnet structure is bright and shiny. Lastly, the +/- terminals are marked for polarity and have never been soldered on the spades. It’s an exceptionally well-preserved woofer overall. Most importantly, it’s been fully tested and sounds great—fast, detailed midrange and strong bass for the platform size. Plus, I tested its DC resistance at 3.9-4.0Ω consistent with a nominal 4 ohm driver rating. Lastly, the basket measures 5¼” across, 5⅞” from corners, it stands 3¼” tall, and the mounting holes are spaced 3⅞” adjacent / 5½” diagonal apart, c-t-c. As pictured and described, this Polk Audio 5¼” poly cone woofer is offered at a competitive price.
