hi, i've got a vox ac30cc2 and it operates at 8 ohms normally (both of the internal speakers are also 8 ohms a piece), but you can set the ohmage to 16 for an extension cab. I scored a 16 ohm weber speaker in the emporium... obviously i need 1 more speaker though. - will it work in the cab as long as I set the amp to 16 ohms??? i.e. 2x16 ohm speakers in a cab set to 16 ohms?? - does the second speaker also have to be 16 ohms, or will 8 ohms work?? - will 2x16 ohm speakers work with an amp set to 8 ohms, or is it the other way around?
