For sale is a pair of 8 Seas Woofers. These were purchased from Madisound around 2005 and used in the subwoofer cabinets of an Apogee Mini Grand for about a year. I eventually ended up replacing all four with a different model that more closely matched the measurements of the factory drivers Theyve been in their factory boxes since then. Tested and working. https://www.seas.no/images/stories/vintage/pdfdataheet/h0511_p21rfp.pdf Details taken from Seas official website: P21RF/P is an 8 High Fidelity woofer with an injection moulded magnesium chassis. This woofer is a further development of our P21REX, but with a 2 voice coil. It is equipped with a high loss rubber surround and a polypropylene cone which contribute to a smooth frequency response and low colouration. The magnet system is designed to give excellent field symmetry, and consequently low distortion. A bullet shaped phase plug reduces compression due to temperature variations in the voice coil, avoids resonances which would occur in the volume between the dust cap and the pole piece and increases the long term power handling capacity.

Seas p21re it H436 8? woofer.In excellent condition,fully working. The P 21 RE is an efficient, low coloration polypropylene woofer with a magnet system designed to minimize low frequency distorsion, reduce IM and handle high power levels. Although primalily intended for use in medium-sized closed bos enclosures, the special suspension stiffness charactéristic makes it suitable for bass reflex cabinets as well, reducing the delayed cone excursions typical in bass reflex systems at high power levels.
