Front speaker anyone???

My passenger door speaker has decided that it doesn't like the kind of music I play and has developed an annoying buzz when anything with half-decent bass is played. I have done a check with the door panel off and tightened up everything in sight. No change, so the speaker is definitely u/s. I don't fancy putting a different type in as there seems to be a lot of messing about to fit to the adpator ring.

All of which leads me to the question, anyone got a replacement that they are willing to part with if I cross their palm with silver??
