mid range driver recommendations wanted

I am looking for a good quality, OEM style midrange that fits the following requirements:

5" to 6" diameter.

A closed box (Q=.7) f3 point of between 90 and 130 Hz.

30mm+ voice coil although I would settle for 25mm.

A 2nd or 4th order butterworth roll-off at around 3500-4500 Hz at any angle from 0 degrees
to 45 degrees off axis.

A very smooth response in the passband.

Reasonably low distortion and a decent waterfall.

Efficiency is not a major concern but all other things being equal, the greater the better.

Priced at around $30 or so in 100 lot quantities.

If anyone has suggestions or recommendations, I would be greatful.
