Myos15ASub

An active subwoofer built for impact and directivity.
The MYOS15ASub is an active subwoofer fitted with a 15″ driver in a bandpass-loaded enclosure and a 1000 W RMS (2000 W peak) Class D amplifier, adding low-end reinforcement to any installation or show, up to a maximum SPL of 134 dB. Its onboard DSP goes well beyond a simple level control: Enforce mode boosts the low frequencies for extra impact where it counts, while Cardioid and Endfire modes let you shape the subwoofer’s directivity, cutting stage bleed or limiting how far the low end carries behind the system.

Class D amplification built for the low end.
The MYOS15ASub delivers 1000 W RMS (2000 W peak) in Class D to its 15″ driver with a 4″ voice coil, for a frequency response of 40 Hz to 150 Hz and a maximum SPL of 134 dB. The system is protected against short circuits and overheating, with a built-in limiter, for reliable use over time.

A reinforced cabinet for high output in the low end.
The MYOS15ASub is built around a reinforced 15 mm plywood cabinet with bandpass loading. An integral metal grille and textured polyurea finish protect the cabinet, two metal side handles make it easy to carry with two people, rear inserts accept four optional wheels (ATOM-WHEELS kit), and four rubber feet keep it stable on the ground.

Two inputs and two outputs for simple daisy-chaining.
The MYOS15ASub features two line-level inputs on combo XLR/jack 6.35 connectors, and two direct XLR outputs: output 1 carries the signal from input 1, output 2 carries the signal from input 2, so the incoming signal can easily be sent on to another amplification system. This makes it possible to couple the MYOS15ASub directly with other active speakers, other powered systems, or with an amplifier driving passive speakers.

A natural pairing with speakers from the MYOS range.
Paired with a MYOS08A, MYOS10A, MYOS12A or MYOS15A, the MYOS15ASub forms a compact system with it, capable of covering the full spectrum, from deep bass to high frequencies. The subwoofer’s X-OVER setting (60/80/100/120/150 Hz) and the speaker’s adjustable high-pass filter (80, 100 or 120 Hz) are set to the same value for a seamless transition between the two elements. A 36 mm socket on top of the subwoofer accepts a coupling pole to position the speaker directly above it, on a single footprint on the ground, for a setup that’s quick to deploy.

A full-featured DSP at your fingertips.
The MYOS15ASub’s DSP is controlled directly from the rear-panel display and push-rotary knob, no app or Bluetooth needed: turning the knob without pressing it adjusts the subwoofer’s level directly (from MUTE to +10 dB), while pressing it opens up the advanced settings. The mode menu offers two behaviors: Normal for standard front-of-house use, and Enforce to boost the low frequencies for extra impact. The X-OVER menu sets the upper limit of the frequencies reproduced by the subwoofer itself (60/80/100/120/150 Hz), matched to the paired speaker’s high-pass filter.

Cardioid and Endfire: shaping low-end directivity.
The location menu allows, in addition to Normal mode, two MYOS15ASub units to be configured in Cardioid or Endfire to steer the direction of the low end. In Cardioid, the subwoofers cut how much low end reaches behind the array and onto the stage, reducing unwanted bleed for performers. In Endfire, the subwoofers are lined up one behind the other to focus the low end toward the audience and reduce spill to the sides. Both configurations rely on the built-in delay, which sets a delay time in ms, meters or feet to align the subwoofers, and a polarity switch that reverses the signal on one of the two units: two complementary settings for fine-tuning the acoustic sum between the subwoofers and achieving the desired directional effect.
