🎯 Performance That Packs a Punch

At the heart of the AMM108 is an 8-inch low-frequency transducer paired with a 1.7-inch compression driver—featuring a shared-magnet coaxial design that unites both drivers on the same axis. This intelligent arrangement delivers tight, phase-coherent sound reproduction and enhances vocal clarity across the board. With a maximum peak output of 128 dB SPL, it projects crisp, full-range audio to both performers and audiences—ideal for medium-throw scenarios.

The speaker handles continuous power at 150 W (RMS) and can accommodate peaks up to 2400 W, offering both reliability and reserve power when the performance demands it. Its frequency response extends from 75 Hz to 20 kHz at –10 dB, with a tighter ±3 dB response from 88 Hz to 17 kHz, ensuring accurate musical representation with deep lows, articulate mids, and smooth highs.

⚙️ Engineered for Consistency & Coverage

One of the defining features of the AMM108 is Bose’s Beamwidth Matching Waveguide—a proprietary technology that aligns the dispersion patterns of both low and high frequencies through the crossover region. The result is remarkably consistent tonal balance across the 110° horizontal by 60° vertical coverage area, even when the speaker is rotated between vertical and horizontal orientations. Simply rotate the cabinet—no tools needed—to shift coverage patterns as required.

The multi-position layout and wide coverage make the AMM108 suitable for virtually any role, from floor monitor angled at 35° to audience-facing mains or fills—streamlining setup and providing acoustic versatility in a single unit.

🛠️ Flexible Design & Effortless Setup

Carrying just 13 kg (28.8 lb), the AMM108 features an ergonomically positioned handle and a robust Baltic birch plywood enclosure with a durable black polyurethane finish. It includes a built-in 35 mm pole-mount cup for elevated setups and multiple alignment points (4 × M8 and 6 × M10 threaded inserts) for mounting systems such as U-brackets, suspension kits, or tilt mechanisms—making it equally at home on-stage, in a ceiling, or on a truss.

For permanent installations, matching voicing with Bose’s AM array modules and AMU utility loudspeakers means system designers can seamlessly integrate the AMM108 into larger setups without re-EQ’ing between models. Chain multiple units via dual Neutrik NL4 connectors with through-parallel ports for convenient audio routing.
