Danish loudspeaker company Dynaudio today debuted the Sub RCC (Reaction Cancelling Configuration) custom-installation subwoofer. The discreet subwoofer is designed to offer additional low-frequency extension to any audio system while facilitating high-performance 2.1 or surround setups without the issues commonly associated with many in-wall subs. It achieves extreme bass performance within a compact form factor, which can be installed in walls, ceilings or even floors — with no back-box necessary. The RCC topology uses two sets of opposed drivers working together to eliminate unwanted vibration transmission, leaving only the desirable acoustic energy behind. Featuring one-piece construction, the Sub RCC is easy to ship and retrofit because there is no cumbersome back-box to add to its size or the expense of transport.

Weirdly unique features include:

• Mounts on the wall surface or into a standard 2×4 stud-bay before or after construction
• Passive subwoofer design with no complex crossovers
• It’s a one-piece extruded aluminum enclosure design
• Frequency response (+/- 3dB): 16Hz – 160Hz

Amplification is provided by AudioControl and the RS 500 DSP-controlled unit is matched and tuned out of the box for the Sub RCC with Dynaudio EQs and limiters. Installers can also tweak the unit’s graphic EQ if needed.
