I would say if the drivers are working, the crossovers are your next culprit to investigate. I am not sure hopw you would do that other than send them into Revel and have them check them out. It maybe as simple as a resister. And you may be able to find a local repair shop that can check and replace any damaged parts for less money.
Help with Revel F50 and C50
I just bought a pair of Revel F50 and the center model C50 locally. I was told they had issues so I bought them anyway.
All bass drivers have no sound, the mids are out as well! The C50 is in similar condition. I have tested a few drivers and they don't appear to be blown or damaged from my very simple battery test and "feeling" for rubbing. I read that some had corrosion issues in early models on the drivers, don't know because they look OK. Cross overs are $200 each , per driver!! Did I buy paper weights?
