This Infinity woofer is in clean, excellent overall condition. It has a flawless CMMD cone and perfect voice coil dustcap. Plus, the surround is made from
permanent
rubber instead of the fragile foam still widely in use when it was made. Also, the black enameled steel basket while the anodized magnet “bell” cover has some faint oxidation. And, the +/- terminals are keyed for polarity (larger one is positive) and have never been soldered on the spades. Overall, this woofer is quite well preserved.
Most importantly, it’s been fully tested in the factory cabinet and sounds terrific—fast, detailed lower midrange and solid low-end for the platform size. And, it supports 125 watts input power as crossed-over in the ENTRA ONE so it’s a very sturdy driver. Plus, I tested its DC resistance at 4.1Ω, consistent with a nominal 4 ohm driver rating. Lastly, the basket measures 4½” across (5¼” from corners), it stands 3” tall, and the mount holes are spaced 3 7/16” adjacent / 4⅞” diagonal apart, c-t-c.
What’s more, installing the woofer is very simple. Remove the rubber grille-retention grommets from the speaker’s faceplate to access the Phillips-head retention screws. Pull the baffle up gently and remove the +/- wires from the old woofer and then undo the screws holding the woofer to the faceplate underside. Replace the woofer and reattach the faceplate and replace grommets. Done!
This is a great find if you have a blown or damaged woofer in your ENTRA CNETER or other suitable Infinity speaker and will have it sounding its best again in no time! Plus, it’s a smart spare to have on hand since production ended years ago.
As pictured and described, this Infinity 4” CMMD cone woofer is offered at a competitive price.
