L-Acoustics unveils compact coaxial enclosure and sub

AUTHOR: Inavate

L-Acoustics showed off its 5XT ultra-compact coaxial enclosure and SB15m compact subwoofer with KIVA variable curvature line source at Prolight + Sound 2013.

The 5XT is the smallest member of the manufacturers XT coaxial series and is based on a two-way passive design with a nominal impedance of 16 ohms. 

It contains a one-inch diaphragm compression driver coaxially loaded by a five-inch low-mid frequency transducer mounted in a bass-reflex tuned enclosure. 

A 3/8-inch microphone stand insert and two M8 inserts for the ETR5 flying bracket are integrated into the cabinet, which is made of Baltic birch plywood. The 5XT enclosure operates over a frequency range of 95 Hz to 20 kHz. 

The coaxial transducer arrangement produces a 110-degree axi-symmetric directivity output. The 5XT is suitable for various distributed applications, as a main or fill system.

Power and processing for the 5XT is delivered by the LA4/LA8 and the forthcoming LA4X amplified controller, each of which ensures linearization, protection and optimization for the loudspeaker system in its different operating modes.

The SB15m is recommended for use with L-Acoustics KIVA and XT series enclosures, including the 5XT, and extends the operating frequency range of these systems down to 40 Hz.

It features a single 15” driver in a bass reflex tuned enclosure. The vent features a progressive profile allowing laminar airflow and reduced turbulence noise. 

The SB15m cabinet is also made of Baltic birch plywood with a pole-mount socket is integrated into the top. SB15m subwoofers can be flown or ground-stacked as a standalone vertical array or within an KIVA/SB15m array.

Like the 5XT, the SB15m is powered and processed by the LA4/LA8 and the forthcoming LA4X amplified controller.
