The new 2026 - Master 12 Active Subwoofer

TSS Master Subwoofer
The Master 12 subwoofer is the entry into our subwoofer line and offers all Signature models. Offering optimal performance, making it the perfect addition to the bass range in the lowest bass frequencies up to 200Hz especially in medium-sized rooms up to 100m² / 1000ft².
The Master 12 woofers bring our Signature speakers closer to a real concert experience than you could ever imagine.
The Master Woofer design
In terms of design, the Master 12 subwoofer largely corresponds to her big brothers the Master 15 and our loudspeaker models, but with a horn loading opening / bass port to the front. This front-facing bass port enables direct coupling to the room and the entire music system.
Thanks to a defined horn length and horn opening, the Master Subwoofer has the design finesse that enables an optimal time axis for both systems.


Master Power and Sound
Powerful, synchronized, and robust, with unshakeable bass, alongside your Signature Speaker, the Master 12 Subwoofer. You have to hear and experience the Master 12 for yourself to believe it. Equipped with two powerful 12-inch bass drivers per channel and active amplification of 1200W per channel. With the Master 12 Subwoofer, your Signature speaker will experience such a significant improvement in low bass in larger rooms that your system will be elevated to a whole new level of sound quality.
The Master 12 is most efficient up to 200Hz. With the deepest sub-bass down to the lowest bass frequencies, powerful, fast, defined, and individually adjustable, your system will sound so much bigger and more open, creating an unimaginably large soundstage. Available in two configurations - active with an integrated Class D amplifier solution as standard, or passive for use with an external solid state amplifiers including DSP such as symmetrical connection. With integrated volume control on each side, your system can be fine-tuned with extreme precision.
