Stagg AS12B

Battery-Powered PA Speaker for Cable-Free Performance

The Stagg AS12B is a 12-inch battery-powered PA speaker built for performers who refuse to be tied to a wall socket. Class AB amplification drives a 12" woofer with 1.5" voice coil and a 1" compression driver, producing 60 Hz to 20 kHz at -3 dB with a maximum SPL of 120 dB. The integrated 12V/7Ah lead-acid battery delivers up to 8 hours of playback.

Standout Features: Talk Over Ducking and Wireless Stereo

What separates this model from typical portable speakers is the Talk Over (ducking) function on the microphone channel — when a presenter speaks into the mic, music automatically drops in volume, then returns when the mic falls silent. Bluetooth with True Wireless Stereo pairing lets two units link wirelessly for stereo playback. Two UHF wireless microphones ship in the box, operating on 863.3 MHz and 865 MHz.

Acoustic Performance — Driver Configuration and SPL

The 2-way active topology pairs a 12" woofer with a 1" compression driver through a 2.5 kHz crossover, balancing low-end punch with vocal clarity. Sensitivity of 96 dB (1W/1m) and a maximum SPL of 120 dB let the cabinet fill small-to-medium rooms.

• Woofer: 12" with 1.5" voice coil — handles bass and midrange with controlled excursion.
• Compression Driver: 1" — delivers articulate high frequencies for vocals.
• Frequency Response: 60 Hz – 20 kHz at -3 dB — covers the full musical spectrum.
• Maximum SPL: 120 dB — projects clearly across a 50–100 person audience.

Power System — Class AB Amplification and Battery

Class AB amplifier topology delivers 150 W rated power and 300 W peak output. The lead-acid battery removes the need for mains power during street performances and remote venues.

• Rated Power: 150 W — continuous output for sustained playback.
• Max Power: 300 W — headroom for transient peaks.
• Battery: Lead-acid 12V/7Ah — up to 8 hours of cable-free use per charge.
• Crossover Frequency: 2.5 kHz — clean handoff between woofer and compression driver.

Connectivity, Inputs, and Physical Build

Source flexibility is a core design priority: Bluetooth with TWS, a USB media player, and XLR/Jack plus RCA inputs cover both wireless and wired setups. The cabinet measures 380 x 590 x 310 mm and weighs 11 kg, with a telescopic top handle and side handles.

• Inputs: XLR/Jack combo and RCA — accepts microphones, instruments, mixers, and consumer sources.
• Wireless: Bluetooth with True Wireless Stereo pairing — link two units wirelessly for stereo.
• UHF Microphones: 2 included (863.3 MHz, 865 MHz) — ready-to-use wireless vocal mics.
• Dimensions: 380 x 590 x 310 mm — fits on a standard PA tripod stand.
• Weight: 11 kg — manageable for one-person transport between gigs.

Who Is It For — Mobile Performers and Event Hosts

The Stagg AS12B is the right choice for mobile entertainers, DJs, public speakers, and event organizers who need a self-contained PA system that runs without mains power. Solo musicians at outdoor weddings, fitness instructors in parks, and teachers hosting assemblies will all benefit from the included wireless microphones and 8-hour battery life. The Talk Over ducking function helps presenters alternate between music and spoken announcements.
