The Studiomaster Sense 15A+ is a 15-inch active stage monitor combining a large coaxial driver, dual Class-D amplification and onboard DSP in a compact wedge enclosure. Its durable painted finish makes it particularly suitable for professional performers, bands, venues, rehearsal rooms and mobile sound systems.

A fixed 43° wedge angle directs the sound towards performers when the monitor is positioned on the floor. The coaxial driver arrangement also helps reduce the cabinet footprint, making the Sense 15A+ easier to position on stages where space is limited.

The Plus version features a durable painted enclosure rather than the carpet covering used on the standard Sense 15A.

15-Inch Coaxial Driver

The Sense 15A+ uses a 15-inch low-frequency driver with a centrally positioned neodymium high-frequency compression driver. Aligning both drivers on the same acoustic axis helps produce consistent coverage and focused reproduction of vocals, instruments and music.

The 15-inch woofer is fitted with a 75mm voice coil, while the high-frequency compression driver uses a 44mm voice coil. The system provides 80° horizontal by 80° vertical coverage, creating a wide monitoring area for individual performers or groups.

Its frequency response extends from 55Hz to 20kHz, making the Sense 15A+ suitable for vocals, keyboards, electronic drums, guitars and full-range playback.

Dual Class-D Amplification

The built-in dual Class-D amplifier system delivers 300W RMS. A 260W RMS amplifier powers the 15-inch low-frequency driver, while a separate 40W RMS amplifier is dedicated to the high-frequency section.

The Sense 15A+ has a programme power rating of 600W and a peak rating of 1200W. A maximum SPL of 128dB provides the output needed for live stages, rehearsals and portable PA applications.

Integrated DSP Processing

Onboard 24-bit, 48kHz DSP provides equalisation, selectable Live and Monitor operating modes and adjustable delay.

Monitor mode adapts the response for conventional floor wedge placement. Live mode supports vertical operation when the Sense 15A+ is being used as a PA speaker, side-fill monitor or sound reinforcement cabinet.

The DSP delay function provides additional alignment control when the monitor is being used alongside other speakers in a larger sound system.

Multiple Audio Inputs

Two combined XLR and jack inputs allow signals to be connected from a mixing console or other compatible audio equipment. A separate 3.5mm input provides an additional connection for suitable playback devices.

An XLR output provides an onward audio connection for another active stage monitor or powered PA speaker.

Floor Monitor or PA Speaker

A built-in 35mm pole socket allows the Sense 15A+ to be mounted vertically on a suitable speaker stand. This enables the cabinet to operate as a conventional powered PA speaker as well as a floor monitor.

The durable painted finish and strong steel grille provide protection for the enclosure and drivers during transportation and regular stage use. Its coaxial construction also helps keep the cabinet compact despite the larger 15-inch driver.
