“Our vision behind this sound system is quite simple: We worked out the limits of what was technically feasible and wanted to set a benchmark with this sound system, even in a large international comparison.”

— Wolfgang Sauter

A New Approach

Wolfgang Sauter; “With the accomplishment of this sound system we want to set a standard that’s going to be the basis for SUB’s future success “. This quickly became our guiding principle while working on this project.

The reproduction of music via loudspeakers is a physical event, so you must take room acoustics into consideration. Aat Pro Performance, we have always been interested in planning our sound concepts on the basis of this. Not in working against physics, as is often the case in other music venues. We can refer to a wide variety of reference projects (see e.g.: Red Bull Hangar 7 in Salzburg; Grelle Forelle in Vienna). Only by taking new approaches in the planning of sound reinforcement where such results achievable.

Noise Protection in Clubs

Planning a sound system becomes especially difficult as soon as sound insulation has to be incorporated. Ideally, a sound system can reproduce any signal correctly, i.e. in a frequency-neutral and impulse-aligned manner. And all this at the required volume. Ideally, this should also be perceived at every listening position in a balanced, uniform manner and at the same volume. Never heard of it before? 

Wall Of Bass and Line Arrays

In order to achieve a precise and balanced bass reproduction in all places of the venue and for all planned future events, we developed the concept of the Wall Of Bass together with the Austrian loudspeaker manufacturer Lambda Labs. In close cooperation with the manufacturer Ciare, Lambda Labs designed tailor-made Ultra Long Excursion 15″ bass drivers that meet the special requirements of this project. In addition to this, an uncompromising bass solution formed of two QR36 systems from Alcons Audio is used on each side to reproduce the midrange and treble. These QR36 systems can be used as line arrays to connect coherently to the flat wavefront of the bass system.

Sound System – Key Data

– Foundation made of 12m³ reinforced concrete

– 32 loudspeaker enclosure made of concrete – ideal for the perfect resonance-free sound experience

– Backfilled with sand and thus completely separated from the actual building fabric

– the 32 loudspeaker chassis are distributed over the rear wall of the club, 8 wide by 4 high

– The loudspeakers themselves were developed for this specific project

– An absorber wall is installed at the rear of the hall.

These components now lead to the actual principle of the WOB – the entire surface now acting like a single bass chassis. In this way, a coherent wavefront is emitted, which resembles the movement of a piston in a cylinder – only rectangular.
