Drivers are new, purchased direct from ESS Labs.

Nice little 5" closed back mid range speaker, it is a round frame design with a grill.
It is a cloth roll, paper cone design with a healthy magnet, at least 12 oz.
Rated to 60 watts RMS, this would work well in a design up to 250 watts.

At 5 1/8" in dia, it fits into a 4" mounting hole and is 2 1/4" deep.
It is rated at 8 ohms, 60 watts RMS, is ESS Labs part number AC400M.

They are bulk packed and sold in pairs, buy one, you get one pair of drivers.

Frequency response is in the 70 Hz. to 9 kHz. range. In fact running a sweep and listening to the speaker it sounded pretty flat through that range.

Closed Back design, isolated the Mid range Driver. There is no interaction with the woofer.
