The AB1 is a direct reflecting dual 18“ subwoofer that can be used with the AT1 and AT2 line array modules. The subwoofer can be used as universal bass cabinet, too. The very large ventilation construction between the two 18“ speakers avoids flow noise, even at very high loads. The extremely high load capacity enables a sound pressure of 138 dB and a lower cut-off frequency of 30 Hz.

The AB1 available in two versions:
► AB1 with neodymium magnet systems
► AB1 F with ferrite magnet systems
Both variants have identical features and acoustic data.

► Max. sound pressure level 138 dB (30 Hz-500 kHz)
► 2.000 W speaker power capability / 4 ohms impedance
► 2 x 18“ transducers with 4“ voice coil

The AB1 F is a subwoofer system in a rectangular chassis for fixed installations and mobile use. The cabinet is with two high performance 18" speakers (ferrite). The AB1 F is compatible with the AT1 line array speaker as well as other professional MF/HF speaker cabinets. The AB1 F suits for speech and music applications as subwoofer speaker in sound reinforcement systems. The chassis is constructed from 15 mm plywood (birch) and covered with black PolyUrea© finish. The cabinet is equipped with eight grip handles and a front grill with transparent charcoal foam backing. Two speakon connectors (NL4) are mounted at the rear side of the chassis for signal input (input) and signal link (link). The power rating of the AB1 is 2.000 W (RMS), the impedance is 4 ohms.
