Yamaha DXS-18 Powered Subwoofer - 1020 Watts

The Yamaha DXS-18 Powered Subwoofer is a robust and powerful active subwoofer designed to deliver deep, impactful bass for various professional audio applications, including live sound, clubs, and mobile DJ setups. It's known for its high output, efficient design, and advanced DSP features.

Here are the key features and specifications:

Power & Performance:

• Power Output: The DXS-18 features a high-efficiency Class-D amplifier capable of delivering 1020 Watts Dynamic Power (with a continuous rating of 800 Watts). This ample power provides significant headroom for clean, punchy bass even at high volumes.

• Driver: It is equipped with a large 18-inch custom-designed cone woofer with a substantial 4-inch voice coil. This combination allows for powerful low-frequency reproduction with minimal distortion.

• Frequency Response: It offers an impressive frequency range from 32 Hz to 120 Hz (-10dB), ensuring deep and resonant bass that can be felt as well as heard.

• Maximum SPL: Capable of reaching a formidable 136 dB SPL (Sound Pressure Level) at 1 meter, making it suitable for larger venues and events where significant bass impact is required.

• Enclosure Design: Utilizes a band-pass type enclosure. This design is optimized to produce high SPL with excellent efficiency and reduced distortion compared to traditional bass-reflex designs.

DSP (Digital Signal Processing) Features:The DXS-18 incorporates Yamaha's advanced DSP to provide flexible control and optimize performance:

• D-XSUB Bass Processing: This proprietary DSP technology offers three distinct modes to shape the low-frequency response:

  • NORMAL Mode: Provides a balanced low-frequency response.

  • BOOST Mode: Delivers a tighter and more focused bass, often favored for kick drums or more aggressive music styles.

  • XTENDED LF Mode: Extends the low-end frequencies even further, creating a thunderous bottom end for applications requiring extreme sub-bass.

• Selectable X-OVER (Crossover Frequencies): Allows you to choose cutoff frequencies of 80 Hz, 100 Hz, or 120 Hz to seamlessly integrate the subwoofer with various full-range loudspeakers.

• Cardioid Mode: For setups with two or more DXS-18 subwoofers, this mode helps control low-frequency dispersion. It effectively reduces the SPL of bass directed towards the stage (reducing stage rumble and feedback) while increasing bass levels directed towards the audience.

• Protection Functions: Built-in DSP provides comprehensive protection functions (such as thermal, overcurrent, and output limiting) for the speaker and amplifier, ensuring reliable operation even under demanding conditions.

Construction & Connectivity:

• Cabinet Material: Constructed from durable plywood for robust, road-ready performance.

• Finish: Features a highly damage-resistant LINE-X coating (a polyurea finish) that protects the cabinet from scratches, bumps, and weather, maintaining a professional appearance over time.

• Cooling: Employs natural convection cooling, a benefit of its efficient Class-D amplifier.

• Input/Output:

  • Inputs: 2 x XLR (balanced, for left and right signals, or mono).

  • Outputs: 2 x XLR (THRU or HPF POST). These allow for daisy-chaining multiple subwoofers or sending a high-pass filtered signal to full-range speakers.

• Pole Mounts: Features dual pole sockets: one standard 35mm pole socket and one M20 threaded pole socket, offering versatile setup options for mounting full-range speakers on top.

• Handles: Ergonomic side handles for easier transport and setup.

• Dimensions (W x H x D): Approximately 563mm (22.2") x 683mm (26.8") x 721mm (28.4").

• Net Weight: Approximately 49.7 kg (110 lbs).

• Power Connectivity: Standard IEC AC inlet.

The Yamaha DXS-18 is a highly capable and versatile subwoofer, ideal for professionals who need powerful, clear, and controlled bass reinforcement in a variety of live sound environments.
