Description

L-Acoustics PA-PACK-1445 Speaker Pack: Kiva II Line Array (x4), SB15m Subwoofer (x2), and LA4X Amplifier (x1)

The L-Acoustics PA-PACK-1445 Speaker Pack is an all-in-one speaker package that contains the following items:

Kiva II Line Array Loudspeaker (x4)

2-way passive colinear source with two 6.5 in drivers and one 1.75 in diaphragm compression driver - 15-degree enclosure angle with 100° horizontal waveguide directivity for assembling enclosures to achieve a coherent wavefront line source.

SB15m Subwoofer (x2)

Ultra-compact subwoofer featuring a single 15 in speaker with high excursion drivers and optimized laminar vents to maximize LF efficiency - deployed in omnidirectional or cardioid patterns in stacked or flown configurations.

LA4X Amplifier (x1)

System amplifier with integrated DSP controller – 4 x 1,000 W RMS at 4 or 8 ohms.

Features:

  • Kiva II Line Array Loudspeaker (x4):
    • LIGHT - Flown even under the most stringent rigging conditions
