Product Introduction

The StudioMaster TRX15MA is a professional active stage monitor speaker designed for live performances, auditoriums, bands, event stages and professional sound reinforcement applications.

Featuring a 15-inch (40cm) low-frequency driver with a 65mm voice coil, combined with a 34mm compression driver and a 1-inch throat, the StudioMaster TRX15MA delivers powerful, balanced and detailed sound reproduction. Its 2-way speaker configuration supports full-range audio performance, from deep bass and clear midrange to bright and articulate high frequencies.

With a published power rating of 250W, a frequency response of 45Hz–20kHz and a maximum peak SPL of 127dB, the TRX15MA is designed to provide reliable monitoring performance in professional live sound environments.

The TRX15MA features an active monitor design with an integrated power amplifier, reducing the need for external amplification equipment and simplifying system installation and operation.

Its dedicated wedge-shaped monitor enclosure directs sound towards singers, musicians and performers, helping them clearly monitor vocals and instruments throughout live performances.

1. 15-Inch Woofer Configuration – Powerful and Full-Bodied Sound

One of the key highlights of the StudioMaster TRX15MA is its 15-inch (40cm) low-frequency driver, designed to reproduce low and low-mid frequencies.

The large woofer helps deliver solid, punchy and full-bodied bass while supporting the reproduction of drums, musical instruments and background music during live performances.

The 15-inch configuration is particularly suitable for stage monitoring applications requiring substantial sound output, allowing singers and musicians to hear their performances more clearly.

In professional sound systems, the TRX15MA can serve as a full-range stage monitor for various live performance configurations.

2. 15-Inch LF Driver with 65mm Voice Coil

The StudioMaster TRX15MA is equipped with a 15-inch low-frequency driver featuring a 65mm voice coil.

This driver is responsible for reproducing low and low-mid frequencies, helping deliver powerful bass, solid drum sounds and clear low-frequency instrument reproduction.

The 65mm voice coil is an important component of the woofer design, supporting its operation in professional audio environments.

The combination of a 15-inch woofer and a dedicated monitor design makes the TRX15MA a suitable monitoring solution for stages, bands and live performances.

3. 34mm Compression Driver – Clear and Detailed High Frequencies

In addition to its 15-inch woofer, the StudioMaster TRX15MA features a 34mm high-frequency compression driver with a 1-inch throat.

The compression driver reproduces high-frequency content, helping vocals, instruments and other audio details sound clear, bright and articulate.

Its horn-loaded design helps direct and control sound dispersion, allowing performers to hear monitoring signals more clearly from their positions on stage.

The combination of the 15-inch woofer and compression driver creates a professional 2-way loudspeaker system suitable for full-range stage monitoring applications.

4. 250W Power Rating – Integrated Power Amplification

The StudioMaster TRX15MA features a published power rating of 250W and an active design with a built-in power amplifier.

This configuration offers practical advantages over passive monitor speakers that require a separate external power amplifier.

Users do not need to install an additional power amplifier for the speaker, helping save equipment space and simplify system installation.

The active design is particularly convenient for event production companies, mobile bands, stage sound systems and professional audio rental businesses.

Note: The published specification lists 250W but does not explicitly identify whether this refers to RMS, Continuous or Peak power.

5. 45Hz–20kHz Frequency Response – Full-Range Audio Reproduction

The StudioMaster TRX15MA offers a published frequency response of 45Hz–20kHz.

This frequency range allows the speaker to reproduce low, midrange and high-frequency content, helping performers monitor vocals and musical instruments clearly.

• Low Frequencies: The 15-inch woofer delivers solid and powerful bass reproduction.
• Mid Frequencies: Provides clear reproduction of vocals, speech and musical instruments.
• High Frequencies: The 34mm compression driver delivers bright, detailed and articulate treble.

With its full-range reproduction capabilities, the TRX15MA is suitable for various live performance applications, from vocal performances and bands to professional music events.

6. 80° × 60° Coverage Angle – Precise Sound Direction for Performers

The StudioMaster TRX15MA features an 80° horizontal × 60° vertical coverage angle (H × V).

This specification describes the speaker's horizontal and vertical sound dispersion characteristics.

Designed for stage monitoring applications, its coverage helps direct audio towards performers, allowing singers and musicians to hear their monitoring signals more clearly.

Proper speaker placement and angle adjustment can help optimize monitoring performance while minimizing unnecessary sound projection into other areas of the stage.

7. 127dB Peak SPL – High Output Monitoring Performance

The StudioMaster TRX15MA delivers a published maximum peak sound pressure level (Peak SPL) of up to 127dB.

This specification represents the speaker's maximum peak sound pressure capability, making it suitable for stage monitoring applications where clear audio signals are required even when the overall sound system operates at high output levels.

Combined with its 15-inch woofer, compression driver and integrated amplification, the TRX15MA provides a powerful monitoring solution for professional live performance stages.

Note: Peak SPL represents maximum peak sound pressure and should not be interpreted as continuous SPL.

8. 2.2kHz Crossover Frequency – Balanced Frequency Distribution

The StudioMaster TRX15MA features a published crossover frequency of 2.2kHz.

The crossover system divides the audio signal between the low-frequency woofer and the high-frequency compression driver, allowing each component to operate within its designated frequency range.

This frequency division supports the integration of the 15-inch woofer and 34mm compression driver, helping deliver balanced and clear sound reproduction.

It is an important specification in the design of the speaker's 2-way configuration.

9. Active Monitor Design – Simplified Installation and Operation

Unlike passive stage monitors that require an external power amplifier, the StudioMaster TRX15MA incorporates its own built-in power amplification system.

This active configuration offers several practical advantages:

• Reduces the number of external amplification devices.
• Saves equipment installation space.
• Simplifies transportation and stage deployment.
• Makes system connections and operation more convenient.
• Suitable for live bands and professional event production.
• Easily integrated into professional PA systems.

Its dedicated wedge-shaped design also allows the speaker to be placed directly on the stage floor, directing sound towards performers without requiring a separate speaker stand in typical floor-monitor applications.

10. Robust Construction – Designed for Professional Applications

The StudioMaster TRX15MA features a dedicated stage monitor enclosure with overall dimensions of 429 × 635 × 484mm (W × H × D).

The enclosure is designed to accommodate the 15-inch woofer, compression driver and integrated amplification system, making it suitable for professional live sound environments.

With a weight of 24.7kg, the speaker can be deployed in mobile stage systems, auditoriums and professional event applications.

Its wedge-shaped monitor design also allows convenient floor placement, helping optimize listening positions for singers and musicians.
