SE AudioTechnik M-F3A S15 PRO Speaker

The SE Audiotechnik M-F3A S15 PRO subwoofer is a high-performance model designed for sound systems requiring powerful, impactful bass that spreads well in large spaces. With its professional style, it's optimized for performances and events where bass isn't just "heard," it must be "felt."

Introducing the SE AudioTechnik M-F3A S15 PRO Subwoofer

The SE Audiotechnik M-F3A S15 PRO is a high-end powered subwoofer designed to meet professional audio needs with its powerful bass and precise signal control.

The product utilizes a bass-reflex structure combined with a 15-inch speaker driver, allowing for the reproduction of deep bass frequencies in the 40-135 Hz range, providing a solid and powerful sound foundation for the entire system.

Technical parameters of the product to consider:

• Type: Bass-reflex The bass-reflex design enhances bass performance by utilizing airflow from the port, resulting in deeper and more expansive bass. This type of enclosure is particularly suitable for systems requiring strong bass and wide coverage, such as stage or event venues.
• Speaker driver: 1 × 15 inch (ferrite, 3” voice coil): The large 15-inch bass driver delivers more powerful and impactful bass reproduction compared to smaller models. The 3-inch voice coil allows the speaker to handle high power levels, minimize distortion, and maintain stability during continuous operation.
• Frequency range: 40 – 135 Hz (-6 dB) This frequency range indicates that the speaker can go quite deep, creating a clear and deep bass foundation. At the same time, limiting it to 135Hz makes it easy to pair with full-range or floorstanding speakers without overlapping frequencies, ensuring overall balance.
• Sensitivity: 98 dB (1W/1m): High sensitivity allows speakers to achieve higher volume levels with the same input power, thereby optimizing performance and reducing the load on the system. This is especially useful in environments that require loud but stable sound.
• Maximum SPL: 136 dB (peak) The very high sound pressure level allows the speaker to operate effectively in large spaces, ensuring that the bass remains clear and powerful even at high volume levels.
• Amplifier power: 800W (Peak) This power output allows the speaker to handle high-pitched audio passages without losing force. At the same time, it ensures stable performance when used in professional sound systems.
• Integrated amplifier: Class-D, SMPS: Class-D amplifier technology delivers high efficiency, saves energy, and reduces heat generation. This helps speakers last longer, especially during prolonged use or in commercial environments.
• DSP: 48 kHz / 24-bit, latency 1.1 ms The DSP processor allows for precise signal control, resulting in clear bass reproduction without delay or distortion. Low latency ensures better system synchronization when combined with other speakers.
• Advanced signal processing (EQ, Delay, HPF/LPF, Limiter, Phase…): These features allow users to fine-tune the sound for specific spaces, thereby optimizing listening quality. This is a major advantage when used in systems requiring flexible configuration.
• Protection system (Limiter, over-temperature, over-current, short circuit): These safety mechanisms ensure the speaker operates safely, minimizing the risk of damage when used at high intensity or for extended periods.
• Control: Digital encoder The use of digital rotary knobs makes setup faster, more precise, and easier, especially when direct adjustments to the device are required.
• Connections: XLR + PowerCon Professional connectivity standards ensure stable signals and easy system expansion. Users can connect multiple speakers together while maintaining consistent sound quality.
