The SE AudioTechnik 15A W is a high-end 15-inch active subwoofer, featuring a built-in Class-D amplifier and powerful DSP, delivering deep, solid, and well-controlled bass. With its optimized design and advanced APD technology, the product reproduces powerful bass that spreads evenly throughout the space while maintaining accuracy.

Introducing the SE AudioTechnik 15A W Speaker

The SE AudioTechnik 15A W is a high-end active subwoofer from the professional audio brand SE AudioTechnik (Germany), designed to deliver powerful, accurate, and easily controllable bass in modern sound systems.

With its 15-inch bass driver and integrated Class-D amplifier, this product simplifies the system while ensuring powerful and stable performance.

Technical parameters of the product to consider:

• 15 inch driver + 3 inch voice coil: The 15-inch bass driver configuration delivers deep and powerful bass reproduction. The 3-inch voice coil withstands high temperatures, minimizing distortion when operating at high power for extended periods. This configuration is ideal for stage and karaoke use, being both powerful and durable.
• Active subwoofer with integrated 800W Class-D amplifier: The selling point of the 15A W is its built-in amplifier, eliminating the need for a separate power amplifier. Class-D technology combined with an SMPS power supply provides high efficiency, energy savings, and low heat generation, ensuring stable operation even after prolonged use. Setup is extremely quick; just plug and play.
• Frequency range down to 33Hz: The ability to go down to 33Hz allows the speaker to reproduce bass with "depth," revealing the vibration rather than just the sound. This is a huge advantage for powerful music genres like EDM, remixes, or stage performances.
• Wide operating range (40Hz – 220Hz): Not only does it handle sub-bass well, but the speaker also handles upper bass effectively, resulting in smoother pairing with full-range speakers, avoiding any "dropping" or lack of power in the mid-bass region.
• Maximum SPL: 136 dB The high sound pressure level indicates that the speaker can operate effectively in large or crowded spaces while still delivering clear, powerful bass without any loss of breath.
• Omnidirectional design: The bass spreads evenly throughout the space, allowing listeners in various positions to still perceive the bass. It's ideal for enclosed rooms or small to medium-sized open spaces.
• Integrated 24-bit/48kHz DSP: This is an extremely valuable feature. DSP allows you to adjust EQ, delay, phase, and gain directly on the speaker → no external processor needed. You can fine-tune it for tighter bass, eliminating muddiness, and tailoring it to specific spaces.
• Flexible input sensitivity options: It supports multiple input levels such as +14 dBu, +4 dBu, etc., making it easy to connect with mixers, digital processors, or other devices without worrying about signal distortion.
• Professional XLR + PowerCON connection: Ensuring stable signal and excellent noise immunity, PowerCON provides a more reliable and safer power supply compared to conventional power jacks when using high power.
• Body design + APD technology: The thick plywood cabinet, combined with Adaptive Port Design technology, optimizes airflow, resulting in tight, clean bass with minimal muddiness. This directly impacts the "bass quality" in real-world listening.
• Dimensions and weight (33.5kg): It feels quite solid, indicating a sturdy speaker enclosure that optimizes resonance. It has handles and a stacking design, making it easy to move and set up in practice.
