replacement driver for Mission 710 cab

[slindsay]

Hi DIYers,
just recieved a pair of M710s via eBay... with one blown driver!
Turns out to be an UIS (unidentifable speaker), cone frozen solid in
the magnet. Rather than fix it I want to replace it.
Looking for pointers from anyone with experience...
Did a bit of googling phoning and found that;
-Mission is now aprt of AIG, who no longer stock it nor can give any
specs, other than 710s used Peerless drivers.
-Wilmslow Audio sell one Peerless

So many choices! thing is I do't know enough about speakers, or even
all the Thiele Smalls of the original Peerless to try and make a
comparison (http://www.thielesmall.com lists a few, but none seem to
match even what little I have i.e. power, SPL, free air resonance)

Any clues, anybody?
