WTB: Infinity Kappa 62.1i 6.5" (or similar) door speaker(s)

[chromal]

I picked up my miata in January without an audio head unit installed. I counted myself lucky that the doors had Infinity Kappa 62.1i 6.5" speakers installed, but having finally gotten around to installing a spare kenwood head unit, was disappointed to discover that the bass/mid voice coil in my driver-side door speaker was burned out.

WTB: one or two Infinity Kappa 62.1i 6.5" speakers in good working order.

Alternately, I'd consider offers for cheap OEM or other door speakers for my 1993 Miata in the 6.5" range.
