Explanation of the Terminology Used in Naming Speaker Presets

Full Range (Full)

A full-range preset allows the loudspeaker to reproduce almost the entire audio spectrum — low, mid, and high frequencies — from a single cabinet. This makes it ideal for general-purpose sound reinforcement, providing a balanced sound without the need for additional components.

The woofer diameter and its tuning frequency determine the extension and impact of the low frequencies. All full-range presets apply a 2nd-order Butterworth high-pass filter to protect the loudspeaker and ensure reliable performance.

Satellite (Sat)

Satellite presets are designed to reproduce the mid and high frequencies with greater dynamics compared to full-range presets. They are typically used together with a subwoofer, which handles the low-frequency content, to create a complete sound system.

The crossover between the satellite and subwoofer is set at 100 Hz with a 4th-order slope.

Note: This applies only to recently created or updated presets available in the AUDAC Preset Library.

Subwoofer (Sub)

A subwoofer is dedicated to reproducing very low frequencies. It is essential for adding depth and impact to music and effects, particularly in larger venues or setups where low-end clarity is critical.

In AUDAC, subwoofer presets are provided without additional equalization, ensuring a natural sound with improved dynamics and headroom.

In all recently created or updated presets:

• The low-pass filter is set at 100 Hz / 4th-order.
• The high-pass filter is aligned with the tuning frequency of each model, the THD at peak power, and uses a 2nd-order slope.

Subwoofer - Boost (Sub Boost)

The Boost preset is a dedicated mode available on certain subwoofers that enhances low-frequency output. It increases bass presence by reducing energy in the 100 Hz range through equalization, while adding emphasis around the tuning frequencies.

This provides additional punch and fullness, especially at low sound pressure levels (SPL), ensuring a more balanced listening experience.

Near Field (Nearfield)

Near Field presets are optimized for close-up listening, typically within a range of 50 cm to 3 m. They are intended for use in smaller spaces where accurate, direct sound is required, while minimizing the influence of room acoustics.

In AUDAC presets, the Near Field setting applies a high-shelving filter to gently reduce certain mid-to-high frequencies, ensuring a natural balance with minimal phase shift.

Mid Field (Mid Field)

Mid Field presets are intended for loudspeakers placed at greater distances than near field setups, typically between 3 and 10 meters. They are well-suited for larger rooms or outdoor environments, delivering a broader and more powerful sound while preserving clarity and detail.

To maintain balance in the high frequencies, these presets apply a high-shelving filter, compensating for the natural absorption of high frequencies as they travel through the air.

Far Field

Far Field presets are designed for large loudspeaker systems positioned at distances greater than 10 meters from the listener. They are intended to project sound effectively across large rooms or outdoor spaces.

For loudspeakers with multiple preset configuration options, such as single or bridge channel mode and impedance values, this information is included directly in the preset name. This way, you can immediately see the settings that apply to your system, making setup clear and straightforward.

Amplifier Configuration

• Single channel (Single)
• Bridge (Bridge)

Impedance

• 4 Ohm (4Ω)
• 8 Ohm (8Ω)
• 16 Ohm (16Ω)

Examples

• Audac ARCHI210 Sub Boost Bridge 16Ω: This preset is for ARCHI210 in 16Ω configuration where the driving amplifier's channels are set to bridge mode and subwoofer boost EQ is applied.
• Audac VEXO106 Sat Midfield: This preset is for VEXO106 for satellite configuration to use with subwoofers like ARCHI10X in midfield listening applications.
