Need Replacement 10" Trace Elliot Celestion

[OneFlash]

Hi forum readers,

I recently bought a 2x10" Trace Elliot 1028H cab online to go with my 15" cab only to find out one of the 10" 'specially designed' Celestion speakers is shot.

This puppy is designed to handle 400W so I need a solid replacement for the one speaker (or maybe both) that can handle my 500W head. Suggestions as to Celestion suppliers, repairers, or alternative (kick butt) speakers that will handle full range (down to 40HZ they say) and not turn to dust inside that ported cab.
