B112

OVERVIEW
Montarbo B112: portable performance, balanced sound B112 is a professional active 2-way loudspeaker designed for small sound reinforcement systems and mobile PA applications that require higher SPL capability, extended low-frequency performance, and controlled coverage. Equipped with a 12" LF driver featuring a 2.5" voice coil and a 1.35" HF driver, the system offers a frequency response from 54 Hz to 20 kHz and reaches a maximum SPL of 129 dB. The 90° × 60° dispersion pattern provides consistent coverage for short-to-medium throw applications including live music, speech reinforcement, and DJ playback. Amplification is based on a Class D + A/B hybrid architecture supplying 600 W RMS (1200 W peak), cooled via silent convection for reliable fanless operation. DSP features 28/56-bit processing with 24-bit / 48 kHz AD/DA conversion and FIR filters for phase-coherent reproduction. User controls include channel levels, main level, preset selection, input sensitivity, and MIX/LINK routing. Connectivity includes CH1 Combo input, CH2 XLR-F + 1/4" jack input, 3.5 mm AUX mini-jack input, and an XLR-M line output for daisy-chain PA configurations. Bluetooth® 5.0 enables stereo wireless streaming for flexible playback scenarios. The polypropylene cabinet measures 365 × 625 × 345 mm and weighs 17.9 kg, providing rugged portability and compatibility with pole-mount, stacking, and installation points. While optimized for mobile PA usage, B112 can also serve in installation environments requiring elevated SPL and full-range performance.

FEATURES
- Active 2-way loudspeaker for small PA and portable sound reinforcement
- FIR DSP processing for improved clarity and phase alignment
- Extended low-frequency performance suitable for live music and DJ applications
- Bluetooth® 5.0 stereo playback for presentations and multimedia
- Durable polypropylene enclosure suitable for portable and occasional installation use

APPLICATION
Montarbo B112 is particularly well suited to small sound reinforcement scenarios where higher output capability and full-range performance are required. It excels in live music venues, small clubs, rehearsal rooms, corporate events, DJ setups, and mobile entertainment environments, where its extended bandwidth and greater headroom offer noticeable benefit over compact loudspeaker formats. Thanks to its controlled dispersion and onboard DSP, B112 integrates efficiently into portable PA rigs and distributed reinforcement systems. While primarily designed for portable use, it can also be deployed in fixed installations where elevated SPL and full-range coverage are valued, such as multipurpose halls, event spaces, and institutional environments.
