Subwoofer Technology

In 2004 L-ACOUSTICS® introduced a new diffraction model, the DED. The Distributed Edge Dipole was published in the AES journal and provides a logical, predictable methodology for low frequency sound design. The DED model describes how a part of the wave produced by the speaker spreads toward the cabinet edges where it is diffracted with group delay and phase inversion. The DED model is implemented for modeling the physics of cardioid applications and the size of enclosures.

The latest subwoofer design incorporates a vent with a progressive profile and ultra-low vibration walls for a significant gain in peak SPL, laminar airflow and drastic reduction of turbulence noise.

L-ACOUSTICS® subwoofers benefit from the latest acoustic, signal processing and component innovations and deliver an exceptional level of performance while offering multiple modes of operation, whether on the road or in fixed installations.

P SERIES

The L-ACOUSTICS® self-powered coaxial range offers a complete integrated system approach and has been designed to fulfill the highest audio expectations for a broad range of professional sound reinforcement applications.

This compact and versatile package combines all the benefits of on-board amplification, digital signal processing (DSP) and contemporary coaxial transducer technology. The P series both covers the needs of fixed installation by driving down the installation and system set-up costs, and simplifies the logistics for rental businesses with regard to easier storage, handling, transportation and inventory management.

As well as delivering cutting edge audio quality, the integrated amplification and DSP module offers comprehensive transducer protection, a precise system drive engine and optimized on-board preset library. The presets are instantly accessible and provide the sound designer with total creative freedom for any conceivable application.

Mark Lasebnik FOH Engineer Centre street Church Calgary Canada	"As a user of L -ACOUSTICS large format systems, I am very impressed by the fidelity and large sound from small format coaxial self powered speakers, including the 108P, 112P, and SB15P....in fact I've had clients tell us that it sounds more like a Hi-fi than a PA. We have replaced all of our small portable systems from other manufacturers with L-ACOUSTICS in our church".
Elie Khairallah Technical Director Venuetech	"The performance of the P Series is incredible ; it’s small but it’s very efficient."
Danny Lau Director Rightway Audio Consultants	“We appreciate the speed at which this system can be set up, it is very convenient for rehearsals, which this system is frequently used for.”
