With the Tower Mains, HEDD open up new horizons for full range studio monitoring and active audiophile systems and to what they can do and mean for the listener. 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.

Consisting of one main unit (TM 80) that can be combined with either 1 or 2 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 HEDD decided to apply closed box designs only as they principally allow the best approximation to ideal transient behaviour. 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 reflexions 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.

Hedd Tower Mains is a serious system for high end studios and home listeners wanting the most accurate rendition of audio possible. This system’s components need to be specified correctly to your listening environment and usually a demo is advisable. Because we think that purchasing this system needs service and support from real human beings who know audio, we don’t display prices on here. Please contact us to find out more.
