HEDD Tower Mains Standard Powered Studio Monitor - Single, Dark Grey Matte

The majestic HEDD Tower Mains system represents a unique approach to what full-range main monitoring and listening can mean and look like in today’s music world. The Tower Mains Standard configuration includes one 3-way monitor and one subwoofer in a fully closed cabinets with the same footprint as a standard studio monitor. They feature HEDD's AMT driver alongside custom midrange and bass woofers for realistic yet powerful audio. A perfect fit for professional recording studios or post-production suites who want to work better and impress, they are also loved by audiophiles who seek beautiful, uncolored sound in their home

THE PINNACLE OF HEDD MONITOR ENGINEERING

The Tower Mains bring forth an incredibly accurate sonic reproduction with massive low-end and sparkling high-end details. The system is centered around the 3x 300-watt TM 80 main monitor. Its three Class D amplifiers drive dual 7" woofers, dual 4" mid drivers, and HEDD's 1" Air Motion Transformer (AMT) tweeter. The TM 80 reproduces a highly detailed and uncompressed sound with extremely low distortion. The TMS 36 subwoofer provides serious low-end thump with two 600-watt amplifiers pushing four 9" woofers.

AIR MOTION TRANSFORMER: A LIFELONG PURSUIT OF CLARITY

The Air Motion Transformer is an electromagnetic driver, based on the Lorentz force, that moves the air through single folds. The diaphragm itself has an aluminum circuit printed on it and is surrounded by a strong magnetic field.

The Air Motion Transformer driver was invented in the 1960s by the late American/German physicist Oskar Heil as an alternative to the piston-like diaphragm that underpinned transducer designs of the time. Simply put, the AMT's design allowed the driver to accelerate and “breathe” air in and out using a folded diaphragm design which increased the musicality and accuracy in high frequency reproduction. It was first put into commercial use in the AMT1 speaker, manufactured by ESS in 1972.

Klaus Heinz was a young physicist and hifi dealer with a burning interest in sound living in Berlin, and when he first heard the AMT he was taken aback by the difference it made to the recordings he loved. This experience drew him to the Bay Area where he met Heil in 1985. These meetings in turn led Klaus to want to take Heil's AMT design and improve upon it, to create a driver that was more compact and reliable. "What fascinated me most when discussing loudspeakers with Oskai Heil was the fact that he really thought originally," Klaus remembers of those meetings. "He constantly looked for new ways to create sound out of alternating current."
