The L-ACOUSTICS
®
12XTi enclosure is the mid-sized model within the XTi Architectural Series and operates
over the 55 Hz to 20 kHz frequency bandwidth. This response can be extended down to 32 Hz with the addition of the
L-ACOUSTICS
®
SB18i subwoofer.
The system approach developed by L-ACOUSTICS
®
for the XTi series consists of the elements needed to fully take
advantage of the possible configurations and optimize the system. The main components of the system are (see also
Figure 1):
8XTi *  Passive compact coaxial enclosure
12XTi *  Passive multipurpose coaxial enclosure
ETR8XTi *  Mounting accessory for the 8XTi enclosure
ETR12XTi *  Mounting accessory for the 12XTi enclosure
EMBi *  Pole mount socket for the 8XTi and 12XTi enclosures
SB18i  Subwoofer enclosure
LA4 / LA4X  Amplified controller
LA NETWORK MANAGER  Remote control software
SOUNDVISION  Acoustical and mechanical modeling software
* Available in two standard colors: Grey Brown RAL 8019
®
or Pure White RAL 9010
®
(refer to the 8XTi and 12XTi spec sheets).
The XTi series components are compatible with standard L-ACOUSTICS
®
accessories. These accessories include the
L-ACOUSTICS
®
SP.7, SP10, and SP25 loudspeaker cables with respective lengths of 0.7 m/2 ft,
10 m/30 ft, and 25 m/80 ft. These cables allow connection of the 8XTi and 12XTi enclosures to the LA4 / LA4X
amplified controller. Each cable is a 4-conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and
features
4-point Speakon
®
connectors.
The 8XTi and 12XTi are driven and powered by the L-ACOUSTICS
®
LA4 / LA4X amplified controller. These
controllers ensure intelligent protection, filtering, and equalization of the enclosures. Four channels of amplification are
provided along with the OEM factory preset libraries, ensuring the optimization and performance of the systems within
the limits of the recommended configurations.
Each system design configuration should first be modeled and studied using the L-ACOUSTICS
®
SOUNDVISION
software. The software predictions are based on the preset parameters stored in the amplified controllers.
Up to 253 amplified controllers can be interconnected and monitored through the proprietary L-ACOUSTICS
®
L-NET network using the L-ACOUSTICS
®
LA NETWORK MANAGER software.
Detailed description on using the LA4 / LA4X amplified controller, SOUNDVISION and LA NETWORK MANAGER
softwares is beyond the scope of this manual. Please, refer to the appropriate documentation available on the
L-ACOUSTICS
