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.  

1.1

 

Loudspeaker enclosures 

KIVA 

Main enclosure (80 Hz – 20 kHz), 2-way passive , variable curvature WST

®

 line source element. 

SB15m 

Subwoofer enclosure (down to 40 Hz). 

SB18 

Subwoofer enclosure (down to 32 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. 

 

SB18 / SB18i / SB18m  

In this document, the SB18 term and illustration refer equally to SB18, SB18i or SB18m.  

1.2

 

Powering and driving system 

LA4, LA4X 

or LA8 

Amplified controller with DSP, preset library and networking capabilities 

 

Operating instructions 

Refer to the 

LA4, LA4X and LA8 user manuals.

 

1.3

 

Loudspeaker cables 

DO cables (DO.7, DO10, DO25) 

8-point PA-COM

®

 loudspeaker cables. 

Respective lengths of 0.7 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

®

SP cables (SP.7, SP5, SP10, SP25) 

4-point SpeakON

®

 loudspeaker cables. 

Respective lengths of 0.7 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

®

Provided with CC4FP adapter. 

 

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

Refer  to  the 

LA4,  LA4X 

and 

LA8  user  manuals

  for  detailed  instructions  about  the  whole  cabling  scheme, 

including modulation cables and network. 

1.4

 

Rigging elements 

 

Rigging elements or procedures are not presented in this document. 
Refer to the 

KIVA system rigging manual

1.5

 

Software application 

SOUNDVISION 

Proprietary acoustical and mechanical 3D modeling software. 

LA NETWORK MANAGER 

Remote control and monitoring of amplified controllers.
