With the HEDD Tower Mains, we open up new horizons for full range studio monitoring systems and to what they can do and mean for the sound engineer. 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. They are more than just tools: They give recording and mastering engineers superior acoustic control over their work.
A modular Main Monitoring system
Modern Main Monitoring Systems have to be cost-effective and flexible enough to work in every possible studio environment. That’s why we designed the HEDD Tower Mains with a modular approach in mind.
They consist 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 it was 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.
Configurations
HEDD TM 80 and TMS 36 can be configured in different ways as they are designed to complement each other. Subwoofers often enough tend to disintegrate the sound image as they have to play with an unknown satellite partner speaker. Unknown means that the low pass filter of the sub and the high pass filter (or behaviour) of the satellite speaker cannot be foreseen and consequently not be optimised.
HEDD Tower Mains complement each other. 4th order Linkwitz-Riley filters are applied on both units, the mechanical transfer behaviour of the two speakers is taken into account. A minimum phase behaviour and a homogeneous sound are achieved that way, even if the units are placed in slightly varying positions.
The different configurations shown in the drawings offer flexible solutions for different control rooms. Depending on their size a second subwoofer may become desirable, and last not least the TM components allow no compromise multichannel solutions both for High End recording studios and Home Theatre installations.
