Setting the Standard for Sonic Accuracy
The Tower Mains Standard represents the apex of HEDD’s audio engineering mastery, dishing out truly chest-thumping bass, superb high-end detail, and a level of sonic accuracy so profound that it’s sure to draw the envy of mixing engineers the world over. This fully closed system starts with a TM 80 main monitor, boasting a trio of 300-watt power amplifiers. These pristine Class D amplifiers drive the TM 80’s 3-way setup of dual 7-inch woofers, dual 4-inch midrange drivers, and HEDD’s world-renowned 1-inch AMT tweeter. You’ll hear every nuance and detail of your mix like never before, thanks to the TM 80’s rich, nearly uncompressed dynamics, minimal distortion, and enveloping three-dimensional wash of sound. To solidify the bottom end, the TM 80 comes mated to the TMS 36 subwoofer — a pure low-end machine that matches the might of the TM 80 with two 600-watt power amps and a quartet of 9-inch woofers. And while the Tower Mains Standard system is perfect for studios, its pure and uncolored response is sure to thrill even the most demanding of audiophile ears!
HEDD’s innovative Air Motion Transformer tweeter
The lucky Sweetwater employees who have experienced the Tower Mains’ mighty sound never fail to home in on its immaculate transient response and almost unmatched level of top-end detail. The key is HEDD’s AMT (Air Motion Transformer) tweeter—arguably HEDD’s flagship technology, revered among the world’s most demanding studios and audiophiles for its superlative high-end information.
In fact, the AMT’s legacy stretches all the way back to the 1970s, when American/German physicist Oskar Heil invented it as a superior alternative to the transducers of the time. HEDD found that Klaus Heinz had heard Oskar’s AMT design, teamed up with Oskar in the 1980s, and eventually improved upon the design. Thus, the AMT design that HEDD listeners enjoy today was born in 2015, transformed from a bulky driver to a small and exceptionally detailed tweeter. The AMT tweeter supplies high frequencies in an incredibly linear manner, is essentially distortion-free, and grants a natural sound to rival the most revered tweeters on the planet. For studio engineers and audiophiles after the most organic and defined top-end response possible, audition HEDD’s AMT tweeter allows you to hear your tracks and mixes like never before
