yeah, funny you mention JBL.

If memory serves me right, which it does! i remember gluing peices of scrap MDF into my old JBL speakers corners to prevent them from seperating. One of the side panels had aready started to seperate from the front baffle. Hmm. how lovely. well they arent going anywhere now because they got about an extra pound of glue in there and some wood blocks.

These arent old speakers either. at the moment theyre about 3 years old i think, theyre the ND310's. still got em but they dont see much use.
