Augspurger® MONOLITH TOWER 215.18


The Monolith Tower Series picks up where the Treo Series leaves off. As the name implies, these systems are noteworthy for their imposing elegance and power that matches our larger main monitor systems. The Monolith Tower 215.18 3-way full-range active monitor breaks new ground for quality audio reproduction in both audiophile playback and mastering reference settings or for personal or corporate theater environments.

Equally at home in a mastering facility or high-end listening and playback environment, the Monolith Tower 215.18 combines the elements of our Duo 15/SUB 18 system into a single integrated cabinet.

By incorporating our unique CiC (cab-in-cab) technology we are able to seamlessly integrate our 18” sub-bass cabinet into the main double 15” 2-way system. This arrangement perfectly time-aligns all frequencies and delivers a high-impact listening experience with subtle mix details clearly revealed, all from a surprisingly compact footprint.

The vertically oriented cabinet provides the extraordinary power and detail of any Augspurger® system in a wonderfully elegant format that offers an efficient integration into the listening environment with minimal footprint. The larger driver complement of the Monolith Tower 215.18 and our high power amps provide superbly balanced sonic precision with extended low frequency extension and dynamic power. Augspurger® Power SXE-3D networkable amps also provide powerful DSP for the ultimate system control and acoustical integration into your environment.

Sporting in-room frequency response of 22 Hz – 20 kHz and output of 127 dB SPL, Augspurger® continues to establish a new market standard in powerful, full-range professional monitoring. Professional users include Ginger Studios, Melbourne, Australia and the artist Motiff. Each system is expertly hand built and tested in Hanover, MA USA.
