SYSTEM COMPONENTS 

The system approach developed by L-ACOUSTICS

®

 consists in offering a global solution that guarantees the highest 

and most predictable level of performance at any step of loudspeaker system deployment: modeling, installation, and 
operation. A complete L-ACOUSTICS

®

 system includes enclosures, amplified controllers, cables, rigging system, and 

software applications.  

2.1

 

Loudspeaker enclosure 

K2 

Full range (35 Hz – 20 kHz), 3-way active, variable curvature WST

®

 line source. 

K1-SB 

LF element arrayable with for K1 and K2 (down to 34 Hz). 

SB28 

Subwoofer (down to 25 Hz). 

 

Loudspeaker system design 

Sound design aspects are beyond the scope of this document. However, the various applications of the 

system will be based on the loudspeaker configurations presented in this document. 

2.2

 

Powering and driving system 

LA4X, LA8 or 

LA-RAK 

Amplified controller with DSP, preset library and networking capabilities 

 

Operating instructions 

Refer to the

 LA4X, LA8 

and

 LA-RAK user manual.

 

2.3

 

Loudspeaker cables 

DO cables (DO.7, DO10, DO25) 

8-point PA-COM

®

 loudspeaker cables (4 mm² section). 

Respective lengths of 1.1 m/2.3 ft, 10 m/32.8 ft, and 25 m/82 ft. 

DOSUB-LA8 

Breakout cable for four passive enclosures. 

8-point PA-COM

®

 to 4 × 2-point SpeakON

® 

(4 mm² section). 

SP cables (SP.7, SP5, SP10, SP25) 

4-point SpeakON

®

 loudspeaker cables (4 mm² section). 

Respective lengths of 1.1 m/2.3 ft, 5 m/16.4 ft, 10 m/32.8 ft and 25 m/82 ft. 

SP-Y1 

Breakout cable for two passive enclosures. 

4-point SpeakON

®

 to 2 × 2-point SpeakON

® 

(2.5 mm² section). 

Provided with CC4FP adapter. 

 

Information about the connection of the enclosures to the LA amplifiers is given in this document.  
Refer to the 

LA4X, LA8 

and 

LA-RAK user manuals

 for detailed instructions about the whole cabling scheme, 

including modulation cables and network. 

2.4

 

Rigging element 

 

Rigging elements or procedures are not presented in this document. 

Refer to the 

K2 rigging manual

2.5

 

Software application 

SOUNDVISION 

Proprietary acoustical and mechanical 3D modeling software. 

LA NETWORK MANAGER 

Remote control and monitoring of amplified controllers 

 

Using L-ACOUSTICS

®

 software 

Refer to the 

SOUNDVISION user manual 

and the 

LA NETWORK MANAGER tutorial
