Sessiondesk SBX Sub Bass Trap - 90s Black

The Sessiondesk SBX Sub extends the performance of the SessionbloX system into the low-frequency spectrum, targeting the most difficult range to control in studio environments. Engineered as a modular bass trap, the sub integrates seamlessly with core panels to balance rooms where low-end build-up and standing waves are most challenging. Mastering the placement of the SBX sub panel in a room is essential for achieving the most efficient low-frequency control. The panel must be positioned in high-pressure zones, such as walls and corners where modal energy naturally accumulates. The SBX sub is a directional membrane absorber: its composite membrane is located on the back of the unit indicated by the wave, and must face a rigid boundary to function optimally.

When placed directly against a wall or corner, the SBX sub’s membrane resonates most strongly in the 70 – 80 Hz region. When installed 20 cm / 8 in away from a rigid boundary, the effective air gap increases and the tuning shifts lower, making the panel most effective around 40 – 45 Hz. When placed 40 cm/16 in away, the operating frequency drops to approximately 30 – 35 Hz. For effective low-frequency control, the SBX sub should be placed within 60-80 cm/24-31 in of a rigid boundary. Beyond 100 cm/40 in, its tuning falls below the useful audible bass range and efficiency is significantly reduced.

SESSIONBLOX ACOUSTIC TREATMENT SYSTEM

SessionbloX is Sessiondesk's modular acoustic treatment system that reimagines studio acoustics as reconfigurable building blocks. With its unique tool-free SBX x-connector system, SessionbloX allows producers and engineers to effortlessly set up and modify their acoustic treatment, from fully treated control rooms to vocal booths and wheeled gobos, all built from the same core components. At the center of the SessionbloX family stand the SBX core and SBX sub, Sessiondesk's flagship high-efficiency acoustic panels. Engineered for precision, the SBX core handles broadband frequencies while the SBX sub targets deep subsonic energy. Beyond their acoustic power, they represent a commitment to health and sustainability: free of mineral wool and synthetic foams, both panels are built with a 100% natural wood fiber interior, ensuring a listening environment that is as safe as it is great-sounding.
