Pair of Seas MR18REX/XF (H1699) 7" Midrange Coaxial Speaker Drivers

Description

Seas MR18REX/XF (H1699) 7" Midrange Coaxial Speaker Driver
For sale is a pair (qty=2) of the legendary Seas MR18REX/XF (H1699) co-axial driver. I have two pairs of these drivers available.
This is a current Seas product, and can be found new on Madisound's website for 2.50 each (5.00/pair plus tax and shipping). I am selling these because I changed to a different driver for technical reasons, and I no longer need these. My loss is your gain!
Condition:  New, open box.
I opened the packages
to measure the impedance and Thiele-Small parameters,
but both sets are otherwise new. The drivers are in perfect condition, and work as new. The cast-metal frames and connectors are all in Excellent to New condition as shown in the pics. This is like buying brand-new drivers for a lower cost.
For each winning bid, I will ship two co-axial speaker drivers in the original packaging as shown in the pictures. (One auction/buy-it-now is for one box containing two Seas co-axial drivers as shown in the pics.)
From the Seas website:
"The MR18REX/XF is a midrange coaxial loudspeaker providing high quality sound in a very compact format. The cone of the midrange acts as a horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn.
The coaxially arranged precoated fabric dome high frequency unit has a smooth frequency response, and integrates with the cone driver to a point source. Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels.
The pre-coated reed-paper cone acts as a piston throughout the recommended frequency range.
The completely new rubber surround reduces resonances and prevents surround break up in the midrange band. The surround’s small inverted roll, combined with a profile that follows the shape of the cone, results in almost total elimination of diffraction effects on the tweeter’s output."
Thanks for looking!
