Its 30mm coil and 100mm magnet ensure an incredibly efficient and reliable speaker with outstanding sound quality. The aluminum tweeter’s housing pivots for adjustable off-axis treble response. The speaker also has a three-position EQ switch for a better off-axis response. The bass/midrange driver’s diecast chassis provides extra rigidity which results in a cleaner, faster bass. The blue Aramid Fibre cone means that the unit is well hidden behind the grille but still produces a remarkably clear and dynamic sound. Incorporating QuickDogs™ and plug-and-play functionality it is quick and easy to install.
