ASCENDO The 21 SUB PRO Active Vented : High-end performance fully active DSP controlled 21″ subwoofer
The 21 SUB PRO ACTIVE VENTED impresses with its unrivalled volume level of 130 dB continuous and 133 dB peak power output.
For a better understanding: The 21 SUB PRO ACTIVE VENTED is significantly more powerful and louder than eight standard 18″ subwoofers combined.
The 21 SUB PRO ACTIVE VENTED also joins this unique performance to an outstanding bass capability.
Compared to conventional motor concepts, the ultra-modern double-gap motor of the custom-made 21″ driver with two outer and two inner voice coils enables much faster directional changes with higher sound power and significantly lower power compression.
The 21 SUB PRO ACTIVE VENTED is particularly suitable as a bass system in large home cinema installations or commercial cinemas for uncompromising demands.

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.

The integrated room acoustic correction tool eliminates standing waves / room modes in a highly efficient way.
Absolutely fascinating how The 21 SUB PRO ACTIVE VENTED transmits the entire low frequency spectrum into the cinema auditorium by performing so veeringly and physically with both highest detail resolution and perfect timing.
The 21 SUB PRO ACTIVE VENTED 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.
The 21 SUB PRO ACTIVE VENTED – Sovereignty + accuracy on the highest performance level.
The 21 SUB PRO ACTIVE VENTED is suitable as a bass system in large home cinema installations or commercial cinemas, for uncompromising demands. We recommend a minimum of 2 subs, but for very large (auditorium / commercial cinema) installations the number may be extended.
The latest generation of highly efficient Class D amplifiers powers the ASCENDO subs. No fan noise can disturb the listening experience because the amps are passively cooled.

“Whatever approach you take to applying room correction to the equation, the end result is utterly fantastic sound that, if viewed from a two-channel, high-end audio perspective “takes care of business” in terms of soundstage, imaging, dynamics, neutrality… you name it. Without a doubt, these are the finest sounding speakers I’ve had my home, and I’m not even able to come close to maxing them out.
What I can speak to, directly, is what a phenomenal job the 2.1 channel system (ASCENDO CCRM12-MKII fronts and ASCENDO SMS21 Subwoofer) did with music. The performance is simply excellent, competing with the best speaker systems I have heard, full-stop.
Can you tell I am impressed with Ascendo Immersive Audio? A taste of its CCRM12-MKII speakers and SMS21 subwoofer is enough to let me know this is a company that has put together a compelling solution for high-end home theater. It’s worth consideration and serious investigation, especially if a top-level dedicated home theater goal of yours is to achieve sublime sound. Ascendo’s is a very nicely engineered system – and by system I mean the whole package, speaker, DSP and amplification – that’ll take a home theater experience to the outer limits.
With its impressive offering, I’m giving a Top Choice award to the Ascendo Immersive Audio CCRM12-MKII speakers as well as the SMS21 subwoofer. Together they delivered superior sound matched by few other 2.0 or 2.1 systems that I’ve heard, and furthermore played a starring role in a 4.1.4 Atmos system that gave a hint of the performance that a full-on Ascendo-equipped home theater can deliver.” – Mark Henninger
