I'm looking at one of those speakers right now, it looks like the actual leads from the speaker are stranded coper wire that comes out of the housing and is soldered to the terminals mounted on the sides, I don't think you'd hurt it if you sniped the wires then removed the spars for the terminals and soldered your speaker wires directly onto the coper wire leads.
you also have to figure out how to mount the thing, I'm trying to find something with the right outer/inner diameter to glue mine to.
