Offered for your consideration is a vintage Definitive Technology 4½ inch poly cone woofer that was original equipment in my ProCenter 100 center channel speaker, USA-manufactured in 1999. It may also be correct for other Definitive speakers from this production era such as the ProCinema 80, but the buyer is responsible for assessing its suitability for any other application.

So, please take a look at my large photos and read the remaining description to decide if this capable Definitive woofer should be yours.

*Although the listing is written in singular to avoid any confusion, two (2) Definitive Pro Center 100 woofers are available at the time of this writing. Please choose if you’d like to buy one or more in the quantity field at the top of the listing. Any additional shipping cost needed will be applied at eBay checkout.



This Definitive woofer is in clean, excellent condition. It has a flawless poly cone and perfect dustcap. Plus, the surround is permanent rubber and the video-shielded magnet structure looks great as well. Also, the black-enameled cast steel basket has no dings or scratches. And, the +/- terminals are marked for polarity and have never been soldered on the spades. Overall, this burly little woofer looks practically new!



Most importantly, it’s been fully tested and sounds terrific with fast, detailed midrange and stout low end for the platform size. Plus, I tested its DC resistance at 6.1-6.3Ω, consistent with a nominal 8 ohm driver rating. Lastly, the basket measures 4⅛” across (4⅞” from corners), it stands about 2¾” tall (incl. the surround roll), and the mount holes are spaced 3¼” adjacent / 4½” on the diagonal apart, c-t-c.

This is a nice find if you have a blown or damaged woofer in your ProCenter 100, or other suitable Definitive model, and will have your speaker working great again in no time!

As pictured and described, this Definitive Technology 4½” woofer is offered at a competitive price.
