HEDD Audio BASS 08

The HEDD Audio BASS 08 is a compact 8-inch active subwoofer built on the same 96 kHz / 32-bit SHARC DSP platform as the MK2 monitor range, bringing professional-grade low-frequency control and system integration to studios of any size. Designed to pair with HEDD’s TYPE 05 and TYPE 07 2-way monitors, the BASS 08 extends usable frequency response down to 24 Hz — and to 19 Hz in LFE mode — while Group Delay Compensation ensures true phase alignment between the subwoofer and satellite monitors for a cohesive, time-accurate system. CTRL software unifies the entire HEDD MK2 and BASS ecosystem from the listening position, with real-time access to Lineariser filtering, crossover settings, variable phase, and Satellite OFFSET control. Providence Sound And Vision carries the BASS 08 in Los Angeles as a flexible foundation for professional sat-sub monitoring systems and Atmos installations.

Key Features

• 8-Inch Woofer with 300 W ICEpower Amplification: A long-throw 8-inch driver with a 2-inch voice coil, powered by a 300 W ICEpower amplifier, delivers 105 dB SPL at 1 m with the controlled, detailed low-frequency response suited to professional monitoring environments.
• Group Delay Compensation (GDC): A DSP tool developed specifically to address the longer group delay inherent in subwoofers, GDC aligns the BASS 08 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 08, maintaining phase and imaging coherence across the full HEDD system.
• Closed or Ported (CoP): A POM plug switches the BASS 08 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 08 to integrate cleanly with a wide range of satellite monitors and room configurations.
• Low Frequency Mode: Extends the lower boundary of the BASS 08 to 20 Hz for applications where sub-bass reproduction and room-shaking dynamics are required.
• 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 08 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 08 is built with premium components, individually tested before shipping, and backed by a 5-year warranty after registration.
