Design & listening
A complete system in one slim cabinet.
Tower 3 Signature integrates the SAT MK3.3 design approach with a 31 cm side-mounted bass driver in place of the compact monitor’s rear driver. A purpose-designed plinth gives the slim cabinet a stable footing.
Bespoke Audax midrange drivers, a Mundorf AMT tweeter and an SBA Acoustics bass driver form two independent sections. The connector supports bi-wiring or bi-amping.
