SE AudioTechnik B 18A speakers

The SE AudioTechnik B 18A is a high-end 18-inch active subwoofer with a built-in high-power Class-D amplifier and advanced DSP signal processing. It delivers deep, powerful, and rich bass, making it suitable for professional karaoke systems, stage performances, and events.

Introducing the SE AudioTechnik B 18A Subwoofer

The SE AudioTechnik B 18A is a high-end active subwoofer from the German brand SE AudioTechnik, designed for professional sound systems requiring powerful, deep, and stable bass.

Featuring an 18-inch bass driver combined with a 4-inch voice coil, this product delivers powerful bass reproduction with a deep, expansive soundstage in large spaces.

Technical parameters of the product to consider:

• 18 inch driver + 4 inch voice coil: This configuration is considered "full power" in the subwoofer segment. The 18-inch bass driver delivers deep bass and a distinct vibrating effect, while the 4-inch voice coil ensures excellent heat resistance, preventing loss of power or distortion even during prolonged use. This forms the foundation for a thick, deep, and powerful bass sound.
• Integrated 1600W Class-D amplifier: This is an extremely valuable feature. The high power output allows the speakers to deliver strong, powerful sound for large spaces. Class-D + SMPS power supply provides high efficiency, low heat generation, and energy savings. Most importantly, no separate amplifier is needed → the system is much more compact.
• 24-bit/48kHz DSP, 1.1 ms latency: DSP helps process signals accurately, reducing distortion and optimizing sound. EQ, delay, phase, etc., can be adjusted directly on the speaker. Low latency ensures good synchronization with full-range speakers, preventing phase shifts or "bass lag".
• Frequency range down to 28Hz: This is the key selling point. Reaching this level means the speaker can reproduce extremely deep sub-bass, delivering not just the sound but also a vibrating sensation. Perfect for EDM, remixes, and stage performances.
• Wide operating range (34Hz – 210Hz): Not only does it handle sub-bass well, but the speaker also handles upper bass effectively, allowing for smoother pairing with full-range speakers without any loss of frequency range. This results in a fuller overall sound.
• Maximum SPL: 138 dB High sound pressure level → delivers clear bass even in large spaces. Suitable for commercial karaoke, stages, and large events.
• Balanced XLR connection: Professional connection standard, excellent noise immunity, easy integration with mixers, digital processors, or existing sound systems.
• Large box design, weighing 45kg: The heavy enclosure reduces unwanted vibrations and increases bass firmness. The large size optimizes enclosure volume, supporting deeper bass response.
