If you don't find a bad tweeter fuse or a loose connection on the 6 pin plug for the driver leads, you can measure the driver resistances from the plug end without pulling the drivers. Here's the pinout for the plug. The drivers are on 1-2 woofers, 3-4 mid, and 5-6 tweeter.

Nerdorama Thanks for the speaker plug pin labeling and diagram. That could really come in handy someday. I think I'll print it off right now and add it to my 910's manual and papers.
