Eminence PS18-4008 replacement

[AuroraB]

I am trying to give some help to one of the local youth clubs in my area.. fixing a broken subwoofer.....
Originally equipped with an Eminence PS18-4008...
Anyone knows of a direct replacement,-- or have the most essential data, Vas, Fs and Qt, - to find a decent replacement unit ???

That is the old version of Eminence Sigma Pro 18. 3 inch voice coil, 120 oz magnet,6.5mm xmax.

Replace it with Eminence Sigma Pro 18 or get the blown driver [if you still have it] reconed.
