Inside the Nola Viper IIa

Any ideas on the best way to get inside the cabinet, before I start unscrewing things. It appears that one of my midrange drivers got disconnected during shipment. I checked driver with a voltmeter and it appears to be fine, so that means something inside shook loose and I need to reconnect.

Any info on this would be extremely helpful.
Removing the bottom woofer appears to be the simplest approach.
Thnas for your help. got it and got it done, thanks to fellow audiogoner.
