Introducing the SE AudioTechnik B 15W Subwoofer

The SE AudioTechnik B 15W subwoofer is a professional subwoofer from the German brand SE AudioTechnik, designed to add powerful bass to stage, karaoke, and event sound systems.

With its 15-inch bass driver and 3-inch voice coil, this product delivers deep, solid, and powerful bass reproduction, resulting in a fuller and more impactful overall sound.

Technical parameters of the product to consider:

• 15-inch bass driver, 3-inch voice coil: The large driver size helps reproduce deep and powerful bass. The 3-inch voice coil provides better heat resistance, helping the speaker operate stably when continuously playing bass at high intensity. This is a very "standard" configuration for subwoofers used in karaoke and medium-sized stage performances.
• Power 400W RMS / 1600W Peak: This power level is strong enough to deliver solid and clear bass in medium to large spaces. The high peak power allows the speaker to handle high-pitched musical passages well without distortion if paired with a suitable amplifier.
• Frequency response down to 33Hz: The deep bass range helps to reproduce "deep" bass sounds, not only audible but also felt powerful. This is extremely important for remixes, EDM, or karaoke that require clear, powerful bass.
• Operating range 39Hz – 130Hz (-3dB): This frequency range indicates that the speaker handles the bass and upper bass frequencies very well, allowing for smooth integration with full-range speakers without overlapping frequencies.
• Sensitivity 98 dB: High sensitivity allows the speaker to produce a louder volume with the same input power level → saving amplifier power and increasing overall system efficiency.
• Maximum SPL: 136 dB This rating indicates that the speaker can achieve very high sound pressure levels, sufficient for use in crowded spaces or small stages while still ensuring clear and powerful bass.
• Omnidirectional sound direction: The bass spreads evenly in all directions, providing a more uniform bass coverage throughout the space. This is especially useful in enclosed rooms such as karaoke rooms or cafes.
• Professional SpeakON NL4 connectivity: It ensures stable and safe signal transmission when operating at high power. Having multiple input/output ports also makes it easy to connect the system or pair multiple subwoofers together.
• Dimensions & weight (30kg): The large and heavy speaker cabinet demonstrates a robust design, optimizing bass resonance. While slightly heavy, this is compensated by improved stability and better bass quality.
