Stagg AS15B

Battery-Powered PA Speaker for Mobile Sound

The Stagg AS15B is a battery-powered 15" two-way PA loudspeaker for performers who need professional sound away from fixed power sources. A built-in 200W RMS amplifier drives a 15" woofer and 1" compression driver, peaking at 400W with 125 dB max SPL. Running on 100–240V AC mains or its internal 12V/7Ah battery, this model covers outdoor events, mobile karaoke, and street performances.

What Sets This Model Apart

Unlike most portable PA cabinets in this segment, the unit ships with two UHF wireless microphones (865 MHz / 863.3 MHz) with a 20–30 m range. A Talk Over ducking function automatically lowers the music when someone speaks into the mic — a rare feature at this price tier. The onboard media player supports USB MP3, FM radio, and Bluetooth with True Wireless Stereo pairing.

Amplifier Power and Acoustic Output

The built-in amplifier delivers 200W RMS with 400W peak for clean vocal projection. Its 15" woofer uses a 1.5" voice coil for low-end down to 40 Hz, while the 1" compression driver handles highs above the 2.5 kHz crossover.

• RMS power provides 200 W for sustained output and clean vocals.
• Peak Power: 400 W
• Max SPL: 125 dB
• Frequency Response: 40 Hz – 20 kHz — full-range coverage

Battery Life and Wireless Connectivity

The 12V/7Ah sealed lead-acid battery delivers 2–4 hours of cord-free operation and recharges in 2–3 hours. A universal 100–240V AC supply works across European and international mains standards without a converter.

• Battery: 12 V / 7 Ah lead-acid — sealed and rechargeable
• Battery Life: 2–4 hours
• Charge Time: 2–3 hours
• Bluetooth: Yes, with TWS

Inputs, Outputs, and Physical Design

The rear panel houses two XLR/Jack 6.3mm mic inputs with echo and Talk Over, an RCA line input, a 3.5mm aux jack, and an XLR line output. A 5-band EQ shapes the tone, while LEDs show power, battery level, and clipping. The cabinet measures 420 × 680 × 360 mm and weighs 15 kg.

• Mic Inputs: 2 × XLR/Jack 6.3 mm — with echo and Talk Over
• Line I/O: RCA in, XLR out, 3.5 mm Aux
• Dimensions: 420 × 680 × 360 mm
• Weight: 15 kg — manageable with built-in wheels

Ideal Users for the Stagg AS15B

This instrument is the right choice for mobile entertainers, karaoke hosts, teachers, fitness instructors, and small-event organizers who need a self-contained sound system without mains power. Two included UHF wireless microphones make it ready for duets and Q&A sessions straight out of the box. The Talk Over ducking feature is particularly useful for presenters and MCs.
