X 28L is a line array module designed for fixed indoor and outdoor installations requiring high audio quality and extreme durability. Thanks to the two 8'' woofers and the 3'' titanium-dome compression driver, it delivers powerful, clear sound with a constant 110° x 20° directivity. The cabinet is made of high-density polyurethane, while the aluminum grille guarantees protection from dust and rain, thanks to a waterproof fabric layer. X 28L is equipped with array mechanics that allow angle adjustment between modules from 0° to 20° with 2° steps. Up to 16 modules can be connected to the same fly bar. EN 54-24:2008 technical data available in the user manual.

All-weather Performance

Focusing on heavy-duty outdoor and indoor applications in large spaces, X Series speakers are capable of true, concert-level high performance in a compact and robust polyurethane enclosure, installed individually or coupled in array configurations. Featuring line array and point source speakers, all modules are equipped with RCF's best-in-class technologies, including Precision Transducers, horns, and crossovers for optimal coverage and sound clarity.

Superior Transducers

Low Frequencies

RCF low-frequency transducers use high-flux neodymium magnets to deliver maximum current stability, reduced distortion, and excellent thermal efficiency. Each woofer undergoes a rigorous endurance signal tests to guarantee reliability under the most demanding conditions.

High Frequencies

The compression driver voice coil features high-performance materials-including neodymium magnets and titanium domes-for outstanding power handling, superior durability, and exceptionally natural sound reproduction across the spectrum.

TRW Waveguide

The new True Resistive Waveguide (TRW) is the result of extensive refinements in the design of the transducers, enclosure, and vented ports-developed together as part of a fully integrated system. Combined with FiRPHASE processing, the TRW enables the speaker to act as a single coherent source, delivering a precise and stable sound image. Acoustically, the waveguide behaves as a pure resistive load-free from resonances-significantly reducing high-frequency distortion typically associated with conventional horns.

Polyurethane: the ultimate in durability

Rigid structural polyurethane is a durable and stiff technopolymer, ideal for outdoor loudspeakers due to its excellent weather, UV, and corrosion resistance, impact and abrasion durability, and lightweight properties. Its sound-insulating and low-vibration qualities enhance audio performance. These attributes make it a robust and versatile choice for outdoor speakers, ensuring longevity and quality performance in various environmental conditions.
