The speaker on my one-month-old CXL110 blew last night. For the life of me I can't understand how this could have happened. I, and a couple of others who were using the rig, were running it with my AI Clarus head, but the volume never went past the 12 o' clock mark. Now it's gonna cost me more than $200 to get the driver replaced. Has anyone else had a problem like this? Could it be a defective unit, or am I missing something big here?
