Active High-End
18" vented reference Subwoofer





High technology
at audiophile level

127 dB SPL cont. / 130 dB SPL peak. With these outstanding performance values, only an SMS18 can be significantly more powerful and louder than four standard 18" subwoofers combined.

The extremely torsion-resistant and compact enclosure of the SMS18 also allows it to be placed behind the cinema screen.

Compared to conventional motor concepts, the ultra-modern double-gap motor of the custom-made 18" driver with two outer and two inner voice coils enables significantly faster directional changes with a higher sound power and a significantly lower power compression.

In other words: much faster, more precise, louder.

It is unbelievable how fast and exactly this power pack swings in and out, even at reference levels.

Signal - impulse/pressure/goosebumps - silence

Precisely because of this unique combination of timing and bass power, deep and enormously dynamic sound events, such as drum solos, sound so fascinatingly realistic.

Even the most demanding home cinema systems will find the SMS18 literally the ideal basis for a cinema experience of a very special kind.

SMS18 - commanding, stronger and louder - a power pack without equal.
