AVANTGARDE SpaceHorn

Mythos BassHorn Reloaded.

For us as loudspeaker designers, however, the development of a bass horn is one of the greatest technological challenges. As Harry F. Olson, the audio pioneer par excellence, warned:„The design of a horn loudspeaker is usually a long and tedious task.“

We created a legend over 20 years ago with our Avantgarde BassHorn. A horn-loaded bass system that eclipsed everything that had come before in its radical nature. A bass unit that finally catapulted the Trio System into iconic status.

Since 2001, we have installed a considerable number of these BassHorn systems all over the world. We have been able to analyse numerous frequency response measurements in different rooms. We have received feedback from our customers and we have learnt a lot. And so, over time, a profound archive has been created, filled with experience and expertise that is probably unique.

We felt it was time to take the next step and perfect the idea. The SpaceHorn as the latest generation is the sum of the experience gained from 20 years of BassHorn development.

Ahead of its time with technology inspired by the past.

One bass principle. Two versions.

The SpaceHorn is available in two different sizes: Single Drive and Twin Drive.

Both versions are 100% compatible with each other and can be used in combination in one system. This means that it is possible to start with two Single Drive SpaceHorn modules in an upright position in the first expansion stage of the TRIO G3 and later expand the system with two or more Twin Drive modules in a central arrangement.

Single Drive
The Single-Drive version uses a single XB12 bass driver. With otherwise identical dimensions in width and depth, the height of the SpaceHorn in this version is 492 mm.
Thanks to its flatter design, the Single Drive version is particularly suitable for upright installation on the rear or side wall (see installation options).

Twin Drive
In the Twin-Drive version the SpaceHorn is equipped with two XB12 bass drivers and is driven by dual-mono XD-1000 amplifiers, delivering 2 x 500 Watt.
The height of this version is 748mm making it more suitable for horizontal placement or the stacking of modules in larger installations.

We have never been so close to perfection

To further improve sound transformation in the spatial planes (floor, rear and side walls), we have completely redesigned the horn curve of the SpaceHorn compared to its predecessor. The aim was to integrate these spatial planes into the calculations as an extension of the horn.

Hence the name change. “BassHorn” became “SpaceHorn”. A big horn-loaded bass system that understands space as part of the horn function. Your home mutates into a giant horn. For the most controlled bass technologically possible.

With the SpaceHorn we have repositioned the drivers and optimised the horn curve.

We calculated the expansion of the horn with a significantly reduced opening momentum. This allowed us to increase the length of the horn to an impressive 1,898 mm, with no other significant changes to the dimensions. This 40% increase in horn length compared to its predecessor results in a significant increase in sound radiation resistance and therefore an improvement in acoustic performance.

Compared to its predecessor, we have increased the efficiency of the SpaceHorn by an average of 5 dB in the important 40-100 Hz range. This 4x increase in acoustic output means that the XB12 bass driver has to move even less for the same volume. This means even more speed and even less distortion for breathtaking bass reproduction and even crisper sound.

Our goal was to perfect the idea of perfect bass reproduction. We have never been closer.
