The L-Acoustics KIVA II is an ultra-compact, modular WST line source element designed for long-throw applications requiring high output and a low visual profile.
Core Specifications
- Maximum SPL: 138 dB peak.
- Frequency Bandwidth: 70 Hz to 20 kHz.
- Nominal Directivity: Horizontal 100° (symmetrical); Vertical depends on array curvature.
- Transducers: Two 6.5″ neodymium LF speakers and one 1.75″ neodymium HF compression driver.
- Impedance: 16 ohms, maximizing amplifier density (allowing up to 24 units on a single LA12X amplifier).
- Weight: 14 kg (31 lbs).
- Environmental Protection: IP55 rating for moisture and shock resistance.

The L-Acoustics SB15m is a compact, high-power 15-inch subwoofer specifically designed to extend the low-frequency response of the Kiva II line source and XT coaxial series.
Core Specifications
- Maximum SPL: 137 dB peak (when driven by LA4X or LA12X).
- Low-Frequency Limit: 40 Hz (-10 dB).
- Transducer: One 15″ high-excursion cone driver in a bass-reflex tuned enclosure.
- Nominal Impedance: 8 ohms.
- Weight: 36 kg (79.4 lbs).
- Environmental Protection: IP55 rating for moisture and dust resistance.
Design and Performance
- L-Vents Technology: Features a progressive vent profile that reduces turbulence noise and increases LF efficiency even at high output levels.
- Directivity Modes: Can be deployed in standard omnidirectional or cardioid configurations using dedicated L-Acoustics factory presets.
- Vocal-to-Music Transition: While Kiva II is often used for speech, adding the SB15m extends its capability to full-range musical programming.
Rigging and Integration
- Kiva II Compatibility: The SB15m can be flown as part of a vertical Kiva II array or ground-stacked.
- Pole Mounting: Includes an integrated 35 mm pole-mount socket, allowing for the mounting of one coaxial enclosure or up to two Kiva II units directly above it.
- Captive Rigging: Equipped with coupling bars and locking tabs stored at the handle positions for streamlined mechanical assembly.
The L-Acoustics SB18m is a high-power, compact 18-inch subwoofer designed as a universal low-frequency extension for various mobile systems, including the Kara II, ARCS, and Kiva II.
Core Specifications
- Maximum SPL: 138 dB peak.
- Low-Frequency Limit: 32 Hz (-10 dB).
- Transducer: One 18″ weather-resistant cone driver in a dual bass-reflex enclosure.
- Nominal Impedance: 8 ohms.
- RMS Power Handling: 700 W.
- Weight: 62 kg (137 lbs) for the “m” version with integrated rigging.
Key Features
- Enhanced Performance: Provides more impact and lower frequency extension than the SB15m, reaching down to 32 Hz compared to the 15-inch model’s 40 Hz.
- Dual Bass-Reflex Design: Uses L-Vents with a progressive profile to reduce turbulence noise and maximize SPL efficiency.
- Directivity Control: Supports both standard (omnidirectional) and cardioid configurations via dedicated DSP presets.
- Versatile Mounting: Includes an integrated 35 mm pole-mount socket, allowing it to support XT series speakers or up to two Kiva II units
