Electro-Voice and the SB122: The "Pro Sound Reinforcement" Approach in a Transportable Version

Recognized in the sound reinforcement industry, Electro-Voice develops speakers designed to deliver high output while remaining reliable and easy to integrate. The SB122 fits this philosophy: a passive bass cabinet in a 12-inch format, designed to provide the necessary foundation for contemporary music and amplified content, while maintaining a size that is easy to move and install.

For Whom and For What: Enhancing a Satellite System for Live, DJ, or Installation Use

The Electro-Voice SB122 is aimed at users who want to add genuine low-end support to a pair of main speakers: service providers and mobile DJs, bars and small venues, associations, places of worship, or fixed installations seeking more present bass without upgrading to a bulky large subwoofer. In a classic setup, it is placed on the floor, and the 35 mm pole mount allows a satellite speaker to be installed on top for a clean and quick setup.

Design, Performance, and Practicality: A Passive Subwoofer Made to Be Effective

Bass Reflex Design for Full and Projected Bass

Thanks to its Bass Reflex design, the SB122 aims to deliver more generous and efficient bass reproduction within its useful range. The specified frequency response at -3 dB extends from 52 Hz to 145 Hz, a range perfectly suited to relieve your main speakers and enhance impact on the kick drum, bass guitar, and low elements of mixes.

12-Inch Cast Frame Driver: Precision and Power Handling

The EVS12SB driver (12 inches / 305 mm) with a cast frame is designed to withstand sustained use. With a rated power of 400 W continuous and 1600 W peak, the cabinet can be paired with suitable amplification to achieve a solid foundation while maintaining a compact format. Its axial sensitivity is rated at 93 dB, and the maximum level reaches 131 dB SPL.

Integrated Low-Pass Filter: Simplified Integration

The SB122 features an integrated low-pass filter, with the note that no processor is necessary. In practice, this facilitates integration in setups where quick deployment is desired: you can more easily manage the frequency distribution between sub and satellites while keeping wiring and system logic simple. To optimize performance, pairing with compatible main speakers and balanced level adjustment remains key to clean and musical bass.

Field-Oriented Construction

The 15 mm plywood enclosure and durable polyurethane finish are designed to withstand repeated handling. The steel grille protects the driver, the handle eases transport, and the Speakon (NL4) connectors ensure secure connections on stage and during events. All housed in a discreet black color that integrates easily into any sound system inventory.
