djabaley said:Actually, the rubber surround on most new diamond speakers can easily come un-glued after about 1 to 1.5 years of use in hot weather. This will cause minor but noticeable midbass distortion. It happened to both of my M6 midbass units after about 1.2 years of use here in florida. Thankfully, I had purchased them from a authorized dealer and they were replaced immediately free of charge.
Apparantly diamond will be reformulating their glue in the near future.
djabaley said:^ If I understand your post correctly, you think I was implying that the un-gluing was a positive trait of the Diamonds? I was trying to illustrate the potential value that a warranty can bring with it in terms of car audio equiptment.
Even Focals are not imune to trouble. A quick read over at caraudioforum will reveal users who have had their Focal mid-bass cone material come de-laminated. Focal may make 75 thousand dollar home speakers, but I doubt that their cheaper car speakers are as well made.
My point is not to bag on Focal, who unquesionably makes nice speakers. However, it is a fact that car speaker failure rates are enchanced by the less than ideal environmental and electrical conditions to be found in the automotive environment. As such, I feel that - with regards to component speakers - purchasing from an authorized dealer can save headaches down the road.
