SMS21 – next level subwoofer

The SMS21 impresses with its unrivalled volume level of 130 dB continuous and 133 dB peakpower.

For a better understanding: An SMS21 is significantly more powerful and louder than eight standard 18" subwoofers combined. The SMS21 also joins this unique performance to an outstanding bass capability.

Compared to conventional motorconcepts, the ultra-modern double-gap motor of the custom-made 21" driver with two outer and two inner voicecoils enables much faster directional changes with higher sound power and 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

The integrated roomacoustic correction tool eliminates standing waves / room modes in a highly efficient way.

Absolutely fascinating how the SMS21 transmits the entire low frequency spectrum into the cinema auditorium by performing so vereignly and physically with both highest detail resolution and perfect timing.

The SMS21 not only impresses with its ultra-modern high technology, but is also recommended for use in the most demanding home cinema systems. Its immense performance potential and extreme velocity make every home theater sound even more real, offering a cinematic experience of a very special kind.

SMS21 - Sovereignty + accuracy on the highest performance level
