The MasterStack12 is a 4.5-way active modular tower system with 10 drive units housed in sealed enclosures spanning 18Hz to 40kHz with vanishingly low distortion, breathtaking dynamic range and ultra-fast transient response. Every driver has an under-hung voice coil moving inside an advanced geometry motor that enables it make extremely long linear excursions. The ring radiator tweeter is incredibly detailed and produces very wide dispersion out to its highest frequencies. The aluminum cone subwoofers, woofers and midranges radiate as perfect pistons to at least 2.5 octaves beyond their respective bandwidths.
This system includes the pedestal and handles.
