LD Systems SUB 10 A Active Installation Subwoofer – 360W RMS, 118 dB SPL, 10” Bass Reflex Subwoofer LD Systems SUB 10 A – Active Installation Subwoofer, 360W RMS, 10″ Woofer, 118 dB SPL The LD Systems SUB 10 A is a compact active installation subwoofer designed to provide powerful low-frequency reinforcement for professional commercial audio systems. Combining a high-performance 10-inch woofer, integrated Class A/B amplification, and built-in satellite speaker amplification, the SUB 10 A serves as both a subwoofer and a complete system controller for background music and distributed audio applications. Designed for restaurants, cafés, retail stores, hotels, conference rooms, bars, lounges, fitness studios, and corporate installations, the SUB 10 A delivers deep, controlled bass while reducing system complexity through its integrated amplifier architecture. Its discreet design, reliable operation, and installation-friendly features make it an excellent solution for projects where space efficiency, sound quality, and long-term reliability are essential. Key Features of the LD Systems SUB 10 A Total System Power: 360W RMS Subwoofer Configuration: 1 × 10″ Custom Low-Frequency Driver Amplifier Type: Integrated Class A/B Amplifier Maximum SPL: 118 dB Frequency Response: 40 Hz – 150 Hz Enclosure Design: Bass Reflex Cabinet System Function: Active Subwoofer with Integrated Satellite Amplification Satellite Amplifier Outputs: 2 Channels for Passive Satellite Speakers Built-In Active Crossover: Optimized Frequency Distribution Installation Type: Fixed Commercial Audio Installation Cabinet Construction: MDF Wood Enclosure Finish: Black System Composition & Technical Overview The SUB 10 A is designed as the central component of a compact installation sound system. Unlike conventional active subwoofers that only power themselves, the SUB 10 A includes a dedicated 3-channel amplifier section capable of driving both the internal subwoofer and compatible passive satellite speakers. This significantly reduces installation costs and simplifies system design by eliminating the need for separate external amplifiers. Active Subwoofer Section The low-frequency section utilizes a custom-engineered 10-inch woofer housed inside a carefully tuned bass reflex enclosure. Key benefits include: Extended low-frequency response down to 40 Hz Improved bass efficiency Reduced distortion Enhanced low-end impact Consistent performance at higher output levels The bass reflex design allows the subwoofer to produce deeper bass than a similarly sized sealed enclosure while maintaining excellent efficiency. Integrated Amplification System The integrated Class A/B amplifier delivers a total output of 360 watts RMS. Amplification is distributed across three channels: Dedicated amplifier channel for the subwoofer Left satellite amplifier channel Right satellite amplifier channel This architecture allows installers to connect passive satellite speakers directly to the SUB 10 A without requiring additional amplification equipment. Benefits include: Simplified installation Reduced equipment costs Cleaner rack layouts Lower power consumption Improved system integration Sound Performance Despite its compact dimensions, the LD Systems SUB 10 A delivers impressive low-frequency performance suitable for a wide range of commercial applications. Deep and Controlled Bass The custom 10-inch woofer provides strong bass extension down to 40 Hz, delivering warmth and fullness to music playback without overwhelming the listening environment. This makes the SUB 10 A particularly effective for: Background music systems Lounge environments Retail stores Hospitality venues Restaurants Corporate facilities Maximum Output Capability With a maximum sound pressure level of 118 dB, the SUB 10 A provides more than enough output for most small and medium-sized commercial installations. The high SPL capability ensures: Consistent performance during busy operating hours Clear low-frequency reproduction Adequate headroom Reduced risk of distortion Balanced System Integration Thanks to the built-in active crossover, the subwoofer works seamlessly with connected satellite speakers. The crossover automatically directs: Low frequencies to the subwoofer Mid and high frequencies to satellite speakers This improves overall system efficiency while reducing strain on the satellite speakers. The result is: Cleaner vocals Improved speech intelligibility Better musical detail Stronger bass performance Increased system reliability Built-In Active Crossover A major advantage of the SUB 10 A is its integrated active crossover network. The crossover is responsible for dividing the audio spectrum between the subwoofer and satellite speakers. Advantages include: Improved Clarity Satellite speakers are relieved from reproducing deep bass frequencies, allowing them to focus on midrange and high-frequency content. Higher Efficiency The system operates more efficiently because each driver reproduces o
