L-Acoustics' SB15P

Using L-Acoustics’ award-winning coaxial technology and packaged in a high performance, self-powered format, the new P series represents L‑Acoustics’ answer to the increased demand from sound professionals for a compact, plug-and-play solution for no-compromise sound reinforcement and monitoring applications.

Both the 108P and 112P combine the benefits of L-Acoustics’ coaxial XT grade point source technology with the benefits of Class D topology amplification, onboard digital signal processing, and an intelligent rigging system. The addition of a companion self-powered subwoofer SB15P for extended LF response in biamp and triamp configurations widens the performance range of the P series for small- to medium-format applications.

The 112P features a 1.4in. compression driver coaxially loaded with a 12in. low-frequency transducer. This coaxial combination produces coherent point source radiation with axi-symmetric directivity allowing the enclosure to perform equally in any orientation over the entire 90-degree beamwidth of the speaker. State-of-the-art components powered by a high-efficiency 1000W Class D topology amplifier designed for optimized headroom yield outstanding sonic fidelity and dynamic performance with a full exploitable SPL under all circumstances.

The onboard DSP ensures integral digital crossover filtering, component time alignment, and equalization, delivering superior performance and optimized protection of the system. Four instant-recall application-engineered presets combined with the multi-shaped cabinet design allow system flexibility as either a front of house, fill, or floor-monitor system, with or without the SB15P low-frequency extension cabinet. An intelligent and intuitive rigging system allows the 112P to be pole-mounted or flown in a matter of seconds.

The 108P was primarily designed as a live reference monitor with an audio signature similar to that of the DOSC line source arrays. Using a digitally processed 250W to 500W amplifier section, the 108P features a 1in. exit HF compression driver coaxiallyloaded with an 8in. low-frequency transducer. This coaxial loading produces a coherent point source radiation with a 100-degree axi-symmetric directivity, while integral digital crossover filtering, component time alignment, and equalization provide superior sonic performance plus the added flexibility of four onboard application-engineered presets (Fill, Front, Monitor, X-over).

As a result, the superb monitoring fidelity of the 108P can accommodate applications such as classical music or opera, with the added benefit of non-obtrusive visually discrete integration. Combined with plug-and-play convenience, the extraordinary high SPL/size ratio (especially when used in conjunction with the SB15P companion subwoofer) will also satisfy many sound reinforcement requirements in highly demanding live concert situations.

The SB15P was designed as a companion reference subwoofer for the 108P and 112P self-powered coaxial loudspeakers. Featuring a front-loaded 15in. transducer in an optimized sized/tuned vented enclosure, the SB15P combines the convenience of self-powered performance with the flexibility of digital signal processing.

Ideal for portable sound reinforcement, the SB15P provides plug-and-play operation and is equipped with a 1000W Class D topology amplifier module and dedicated onboard DSP with instant recall, application-engineered presets. The 15in. component employed in the SB15P features elevated power handling and excursion capability along with reduced distortion and thermal power compression. Advanced component performance is complemented by integral power amplification and protection to provide exceptional SPL output and secure operation. Optimized tuning provides an ideal combination of temporal accuracy, bass articulation, musicality, and low-end definition that only a front-loaded subwoofer can provide.

A built-in pole-mount socket allows the SB15P to operate as a compact FOH system when used with 108P or 112P enclosures. An optional adjustable U-bracket facilitates ceiling, wall, scaffold, or truss mounting, offering a unique degree of rigging versatility for fixed installations.
