The Tower Mains are fully closed and modular Main Monitors. They deliver the best possible sound of any active all-analog configuration.
Please contact us directly if you wish to learn more or purchase the Tower Mains. We will guide you through the modular options and help you set up the best possible configuration for your needs.
Pure Analog Reference Speaker System
With the HEDD Tower Mains, we open up new horizons for full range studio monitoring and active audiophile systems and to what they can do and mean for the listener. The HEDD Tower Mains let you rediscover what decisive role dynamics play in audio reproduction and how pivotal they are to achieve the highest degree in realism and authenticity.
The Tower Mains consist of one main unit (TM 80) that can be combined with either 1 (Standard) or 2 (Extended) subwoofers per channel. Each sub incorporates 4 drivers in a closed box design and 1.200 W of amplification. The Tower Mains components can be arranged flexibly, depending on the size and geometries of your working space. Due to a sophisticated filter design, you always will have a seamless transition and homogeneous sound: spectacular analog performance meets great versatility.
In the search for precision, it was decided to apply closed box designs only as they principally allow the best approximation towards an ideal transient behavior. The 3 dB lower efficiency compared to ported designs is compensated and even exceeded by having multiple drivers and enormous amplifier power. The TM 80 main unit with its five speakers in a vertically symmetrical alignment – a quasi d’Appolito configuration with the HEDD Air Motion Transformer as the centerpiece – delivers broad horizontal dispersion but a controlled vertical directivity. Thus unwanted reflections from the ground or the ceiling are reduced.
The TM 80 is driven by 3x 300 W amplifiers with a response down to 80 Hz. The matching TMS 36 subwoofer comes with four 9” no-compromise long-throw drivers and 1.200 W of amplifier power – 300 W per woofer to be more specific. Back to back sitting drivers compensate their impact to the enclosure thus avoiding cabinet resonances, their frequency response starts at 20 Hz (-3 dB) and stops at 80 Hz (-6 dB). The TMS 36 Subwoofer delivers an astounding transient response up to very high SPL levels.

"The HEDD TM Extended Tower system is in a select group of the very best loudspeakers I’ve personally heard, and its resolution may well be unrivalled."
