Key Features of StudioMaster SENSE15A+

1. Active Stage Monitor Design – Professional Stage Monitoring Solution

The StudioMaster SENSE15A+ is a professional active stage monitor designed specifically for live performance monitoring applications.

Unlike conventional full-range loudspeakers that primarily project sound toward the audience, stage monitors are positioned to deliver audio directly to performers.

Its wedge-shaped enclosure allows the speaker to be placed on the stage floor and angled toward singers, musicians and presenters.

This arrangement helps performers monitor vocals, instruments and other audio signals during live performances.

The SENSE15A+ is suitable for concert stages, live bands, acoustic performances, auditoriums, churches and professional event production.

2. 15-Inch Woofer – Powerful and Full-Bodied Bass

The StudioMaster SENSE15A+ features a 15-inch (40cm) low-frequency driver with a 75mm voice coil.

Its large woofer supports powerful and full-bodied bass reproduction, helping performers monitor low-frequency instruments during live performances.

For stage monitoring applications, clear bass reproduction is important for musicians who need to hear kick drums, bass guitars and other low-frequency instruments.

The 75mm voice coil supports the driver's power-handling capability, making it suitable for professional audio applications.

3. 1.75-Inch High-Frequency Driver – Clear Vocals and Detailed Highs

The SENSE15A+ is equipped with a 1.75-inch high-frequency driver featuring a 44mm voice coil.

The HF driver reproduces upper-frequency content, helping deliver clear vocals, instrument details and high-frequency information.

For stage monitoring, clear vocal reproduction allows singers to hear their own voices more accurately, while musicians can monitor important audio elements during performances.

Combined with the 15-inch woofer, the high-frequency driver forms a professional two-way loudspeaker configuration.

4. 300W Power – Integrated Amplification for Convenient Operation

The StudioMaster SENSE15A+ features an integrated 300W amplifier, eliminating the need for a separate external power amplifier.

Its active speaker design simplifies system configuration, reduces external equipment requirements and makes installation more convenient.

The speaker can be connected to a compatible mixer or audio signal processing system to receive monitoring signals.

With 300W power, the SENSE15A+ is suitable for various professional stage monitoring applications.

5. 55Hz–20kHz Frequency Response – Full-Range Monitoring

The StudioMaster SENSE15A+ offers a frequency response of 55Hz–20kHz, supporting audio reproduction across low, mid and high frequencies.

Its full-range performance helps performers monitor different audio elements:

• Low Frequencies: Supports kick drums, bass guitars and other low-frequency instruments.
• Mid Frequencies: Provides clear reproduction of vocals, speech and musical instruments.
• High Frequencies: Helps reproduce detailed high-frequency content for vocals and instruments.

This frequency response makes the SENSE15A+ suitable for various live performance configurations, from acoustic stages to professional bands.

6. 128dB Peak SPL – Powerful Stage Monitoring Performance

The StudioMaster SENSE15A+ delivers a peak sound pressure level of 128dB according to the published specifications.

This output capability supports stage monitoring applications where multiple sound sources operate simultaneously, including drums, guitars, vocals and main PA systems.

Its high-output performance helps singers and musicians monitor audio signals clearly from their positions on stage.

Proper positioning, EQ adjustment and volume management are recommended to achieve effective monitoring and minimize unwanted feedback.

7. 80° × 80° Coverage Pattern – Optimized Listening Area

The StudioMaster SENSE15A+ features a directional horn with an 80° horizontal × 80° vertical coverage pattern.

This horn design helps distribute sound toward the intended listening area and supports effective monitoring for performers.

For stage monitor applications, controlled sound dispersion is particularly important because speakers are positioned close to singers and musicians.

The 80° × 80° coverage pattern provides flexibility when positioning the monitor on different stages.

Proper speaker alignment helps improve monitoring performance and manage unwanted sound dispersion.

8. Wedge Monitor Design – Flexible Stage Positioning

One of the key features of the StudioMaster SENSE15A+ is its professional wedge monitor enclosure.

Its angled cabinet allows the speaker to be positioned directly on the stage floor, directing sound upward toward performers.

This design saves space and provides flexible positioning for different stage configurations.

The SENSE15A+ can be used as a monitor for lead singers, backing vocalists, guitarists, keyboard players, drummers and stage presenters.

It is an ideal solution for professional stages requiring multiple monitoring positions.

9. Integrated Active Amplifier – Simplified Sound System Configuration

The StudioMaster SENSE15A+ belongs to the active loudspeaker category, featuring an integrated power amplifier inside the speaker enclosure.

This design eliminates the need for a separate external amplifier dedicated to the monitor speaker.

Its integrated amplification simplifies system setup, reduces external equipment requirements and improves installation convenience.

When used with a professional stage mixer, sound engineers can send dedicated monitor signals to different performer positions according to the requirements of the event.

10. Professional Enclosure – Designed for Stage Applications

The StudioMaster SENSE15A+ features a dedicated enclosure designed for professional stage monitoring applications.

With dimensions of 460 × 510 × 377mm, its wedge-style cabinet supports convenient floor placement without occupying excessive stage space.

The enclosure accommodates the 15-inch woofer, high-frequency driver and integrated amplifier.

This design makes the SENSE15A+ suitable for regular use in concert venues, auditoriums and mobile sound reinforcement systems.

11. 20.5kg Weight – Practical Installation and Transportation

The StudioMaster SENSE15A+ weighs 20.5kg, making it a practical solution for professional 15-inch active monitor applications.

Its integrated amplifier reduces the number of external components required compared with passive monitor systems using separate power amplifiers.

The speaker's dimensions and weight should be considered when planning stage layouts, transportation and installation.

It is suitable for event production companies, mobile bands and professional sound system installations.
