ADAM Audio's S2X brings together the virtues of the "classical" 7" woofer and tweeter combination by using innovative technologies and top-class materials. - Cone 7" woofer is driven by a sophisticated magnet system with a 2" voice coil creating a greater linear excursion. This produces more dynamics than one would assume in a monitor of such small proportions. As a result, in addition to the unsurpassed audio quality of the X-ART and A/B amplifier combination, this monitor surprises the listener with a very powerful, deep, but always tight and precise low end.
