Studiomaster Sense 15A+ 15" Active Stage Monitor Wedge Speaker

Professional 15" 1200W Active Coaxial Stage Monitor With 43° Wedge Angle, Neodymium Compression Driver, Dual Class D Amplification & 24-Bit DSP – Studiomaster Sense 15A+.

The Studiomaster Sense 15A+ is a professional 2-way coaxial active stage monitor designed to deliver crystal clear, accurate audio to performers on stage in a sleek, compact and lightweight package. The coaxial driver design — combining a 15" LF driver with a 1.75" neodymium HF compression driver mounted concentrically on the same axis — delivers improved sensitivity, accurate tone reproduction and reduced distortion compared to conventional 2-way designs, ensuring performers hear a true and detailed representation of their sound on stage. The compact footprint that the coaxial design allows makes the Sense 15A+ an ideal choice for space-constrained stages where monitoring quality and output capability cannot be compromised.

Powered by a dual Class D amplifier delivering 1200W peak power — 260W to the LF driver and 40W to the HF driver — the Sense 15A+ achieves a maximum SPL of 128dB with a full-range frequency response of 55Hz–20kHz. Comprehensive 24-bit/48kHz DSP processing ensures a clinical, accurate sound stage with a built-in 3-band EQ for precise tonal adjustment to suit different stage environments, and a 2.4kHz crossover provides clean, well-defined driver integration. Two XLR/jack combo inputs with individual level controls, a 3.5mm aux input, an XLR main mix output and a link-through output provide flexible connectivity for any stage setup, and a 35mm pole mount socket on the base of the cabinet allows the Sense 15A+ to be used as a front-of-house PA speaker on a standard speaker stand as well as a stage monitor — providing genuine dual-purpose versatility.

Coaxial 2-Way Design For Accurate Stage Monitoring

The coaxial driver configuration of the Sense 15A+ places the 1.75" neodymium HF compression driver concentrically within the 15" LF driver, creating a single point-source sound that delivers improved sensitivity, accurate tone reproduction and reduced distortion compared to conventional separated 2-way designs. This results in a more coherent, detailed and natural monitoring sound that gives performers a true representation of their performance on stage — while the coaxial layout allows for a significantly more compact cabinet footprint than a traditional 2-way design of equivalent output capability.

1200W Dual Class D Amplification & DSP Processing

The dual Class D amplifier delivers 1200W peak power with dedicated amplification for both the LF and HF drivers — 260W and 40W respectively — for a maximum SPL of 128dB and a full-range frequency response of 55Hz to 20kHz. Comprehensive 24-bit/48kHz DSP processing ensures a precise and clinical sound stage with a built-in 3-band EQ for fine tonal adjustment to suit different stage environments and performer preferences, and a 2.4kHz crossover frequency provides clean, well-defined integration between the two drivers across the full frequency range.

Dual-Purpose Versatility & Practical Connectivity

Two XLR/jack combo inputs with individual level controls accommodate a wide range of stage sources, and a 3.5mm aux input provides additional connectivity for media players and other devices. An XLR main mix output and link-through output allow straightforward signal distribution to additional monitors or PA speakers, and a 35mm pole mount socket on the base of the cabinet allows the Sense 15A+ to be deployed on a standard speaker stand as a front-of-house PA speaker when not in use as a stage monitor — making it a genuinely versatile investment for any live sound setup. The 43° wedge angle and 80° x 80° coverage pattern ensure an ideal close monitoring position with wide, consistent coverage for performers across the stage.
