How many times have they got smelly? Can you see the coil at all? What about the impedance reading from them?
What music are you playing with them? If it's not decaf, I would say there is a good chance you are clipping them from the audio source, which should, to my knowledge, still show a stable voltage reading on the electrical system.
What is the box tuned to? Port area? Box size?
Playing below tuning?
Any idea what frequencies you are playing at to get them stinky, or is it any frequency?
Got any pics of them and the box?
