The CWM664 has the same basic features and dimensions as the CWM663, but uses a soft dome Nautilus tube-loaded tweeter instead of an aluminium dome, and a black glass fibre bass/midrange cone instead of blue Kevlar. Installation is just as easy, thanks to our new QuickDogs fixing system and plug-and-play connection.
