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 only the frequencies it is designed to handle.

Reduced Distortion

By minimizing unnecessary driver excursion in satellite speakers, distortion is significantly reduced.

Enhanced Reliability

The crossover helps protect connected speakers from excessive low-frequency energy.

Connectivity & Installation Flexibility

The SUB 10 A offers flexible connectivity options for integration into professional audio systems.

It can be connected to:

• Mixers
• Media players
• Commercial audio controllers
• DSP processors
• Paging systems
• Multi-zone audio solutions
• Background music systems

Its integrated amplifier design greatly simplifies wiring requirements and reduces installation time.

Cabinet Construction

The enclosure is constructed from durable MDF wood, chosen for its excellent acoustic characteristics and long-term reliability.

Benefits of the MDF cabinet include:

• Reduced resonance
• Improved bass accuracy
• Greater structural rigidity
• Long service life
• Professional appearance

Its compact footprint allows installation in discreet locations such as:

• Under counters
• Behind furniture
• Inside cabinetry
• Equipment rooms
• Dedicated installation spaces

Protection Systems

To ensure reliable operation during continuous daily use, the SUB 10 A incorporates integrated protection circuitry.

Protection features help guard against:

• Thermal overload
• Excessive signal levels
• Amplifier stress
• Speaker damage

These systems allow the subwoofer to operate reliably in demanding commercial environments where music may play for many hours every day.
