SIGNUM SL loudspeakers are perfect for replacing original factory
speakers and they even sound very well with the lower amplification
power of the head unit. Besides the good adjustment and the
well balanced sound, ESX made a point on compactness to assure
the installation in almost every vehicle thanks to the shallow
dimensions and small crossovers.
High temperature 25 mm Kapton carried voice coils, poly injection
cones with aluminum look and elastic foam surrounds and the
space saving concealed magnets are standing for a fine drawing
and high definition music playback despite shallow dimensions.
