Powered Line Array System - 18 Inch Subwoofer, Four 12 Inch Line Array Speakers and Mounting Frame
The SAXLP-PKG4 line array system delivers professional sound reinforcement for venues requiring even coverage and high output. This complete powered system combines one 18-inch subwoofer with four 12-inch line array speakers on a dedicated mounting frame, eliminating the guesswork of component matching.
The 18-inch subwoofer produces deep bass response from 35Hz-300Hz with 600 watts RMS power, while each 12-inch speaker delivers full-range output from 48Hz-20kHz using dual 1-inch titanium compression drivers. The line array configuration provides superior throw and pattern control compared to traditional point-source speakers.
Peak power reaches 3,000 watts total (1,200W subwoofer + 600W per speaker), with each component achieving 130 dB maximum SPL. The birch plywood enclosures feature powder-coated steel grilles and high-intensity aluminum suspension hardware. Class AB amplifiers with cooling fans ensure reliable operation during extended use.
This system handles outdoor festivals, concert venues, and large event spaces up to 1,000 people. The line array design minimizes ground reflections while maximizing audience coverage, making it ideal for corporate events, outdoor weddings, and touring applications where consistent sound distribution matters.
Connect via balanced XLR inputs with powerCON compatible power connectors allowing daisy-chaining. The mounting frame secures all four line array speakers for quick deployment and teardown.
Seismic Audio backs this system with a one-year warranty and direct shipping. Professional-grade components at accessible pricing for serious sound reinforcement needs.

Frequently Asked Questions
What size venues can this line array system handle?
This system effectively covers venues up to 1,000 people with its 3,000 watts peak power and 130 dB maximum SPL capability. The line array configuration provides superior throw and even coverage compared to traditional speakers, making it ideal for outdoor festivals, large corporate events, concert venues, and touring applications where consistent sound distribution across the audience area is critical.
What cables do I need to connect this system?
You'll need balanced XLR cables to connect your mixer to the subwoofer's XLR input, then use the XLR output to link to the first line array speaker. Additional XLR cables daisy-chain between the four line array speakers. Power connections use powerCON compatible cables, which can be daisy-chained between components to reduce the number of required power outlets.
How does the line array mounting frame work?
The included mounting frame secures all four 12-inch line array speakers in proper alignment for optimal acoustic coupling. The high-intensity aluminum suspension hardware ensures safe rigging while the frame design allows for quick setup and teardown. The 18-inch subwoofer can be ground-stacked or pole-mounted separately using its built-in pole mount cup.
Do I need additional subwoofers with this system?
The included 18-inch powered subwoofer provides substantial low-end coverage with 600 watts RMS and response down to 35Hz. For most applications up to 1,000 people, this single subwoofer is sufficient. However, for bass-heavy music genres or larger venues, you may want to add a second matching subwoofer to increase low-frequency headroom and impact.
Can this system run on standard household power?
Yes, the universal power supply accepts 100-240 VAC, making it compatible with standard household and venue power worldwide. However, at full output, the complete system draws significant current, so ensure your power source can handle the load. Using powerCON daisy-chaining reduces the number of required outlets while maintaining proper power distribution to each component.
