The top 6in in-ceiling speaker in the CI 600 series. This high-performance speaker features a Nautilus swirl-loaded 25mm (1in) aluminium dome tweeter that pivots for adjustable off-axis treble response. Other highlights include a bass/midrange driver with a rigid die-cast chassis, a three-position EQ switch, superior crossover components, gold plated terminals and an impressive maximum amp power of 150W. Installation couldn’t be easier, thanks to our QuickDogs™ fixing system and plug-and-play connection.
