HEDD Audio BASS 12

The HEDD Audio BASS 12 is a high-output active subwoofer built to extend the low-frequency foundation of professional recording studios and immersive audio installations running HEDD’s 3-way MK2 monitors. A 12-inch driver powered by 700 W ICEpower amplification reaches 20 Hz in standard operation and 16 Hz in LFE mode, delivering 115 dB SPL per unit at 1 m with the precision and control that large-format monitoring demands. The same 96 kHz / 32-bit SHARC DSP platform found across the HEDD MK2 and BASS range brings Group Delay Compensation, Lineariser zero-phase filtering, Closed or Ported mode, and full CTRL software integration to every session. Providence Sound And Vision carries the BASS 12 in Los Angeles for studios running TYPE 20 MK2 or TYPE 30 MK2 systems that require a subwoofer capable of matching their scale and output.

Key Features

• 12-Inch Woofer with 700 W ICEpower Amplification: A long-throw 12-inch driver with a 2.5-inch voice coil, powered by a 700 W ICEpower amplifier, delivers 115 dB SPL per unit at 1 m — providing the headroom and low-frequency authority suited to large-room monitoring and high-SPL immersive installations.
• Group Delay Compensation (GDC): A DSP tool designed specifically to address the longer group delay inherent in subwoofers, GDC aligns the BASS 12 with MK2 satellite monitors for system-wide phase linearity — eliminating the smeariness and spatial disorientation common in traditional sat-sub systems.
• HEDD Lineariser: The same zero-phase filter found in the MK2 monitor range is available in the BASS 12, maintaining phase and imaging coherence across the full HEDD system.
• Closed or Ported (CoP): A POM plug switches the BASS 12 between closed and ported cabinet modes — closed for tighter bass precision and transient resolution, ported for deeper, more extended low-frequency response.
• Variable Phase and Crossover Filters: Adjustable crossover and phase controls, including Home Cinema-compatible Low Frequency Extension, allow the BASS 12 to integrate cleanly with a wide range of satellite monitors and room configurations.
• Low Frequency Mode: Extends the lower boundary of the BASS 12 to 16 Hz for applications where deep sub-bass reproduction is essential to the work.
• Satellite OFFSET Control: Compensates for physical positioning differences between the subwoofer and satellite monitors, maintaining time alignment regardless of placement constraints in the room.
• CTRL Software Integration: Full integration with HEDD’s free CTRL software unifies the BASS 12 and MK2 satellite monitors into a single, controllable monitoring ecosystem with real-time access to all DSP parameters from the listening position.
• Analog and Digital I/O: Accepts balanced analog XLR and AES/EBU digital input; outputs include filtered analog XLR and digital AES pass-through for flexible system routing.
• Assembled in Berlin: Each BASS 12 is built with premium components, individually tested before shipping, and backed by a 5-year warranty after registration.
