Powered 18 Inch Line Array Subwoofer, Powered 12 Inch Line Array Speaker and Mounting Pole
The SAXLP-PKG1 delivers a complete line array solution for touring bands, mobile DJs, and venues requiring professional sound reinforcement with scalable coverage. This powered system combines an 18-inch subwoofer with a 12-inch line array speaker, creating full-range sound that cuts through ambient noise and reaches the back of large rooms.
The 18-inch subwoofer provides deep bass extension down to 35Hz with 600 watts RMS power, while the 12-inch line array speaker handles mids and highs from 48Hz to 20kHz using dual 1-inch titanium compression drivers. Together, they deliver maximum SPL of 130dB per component, giving you clean headroom for demanding live sound applications.
Both components feature Class AB amplifiers with active cooling, balanced XLR inputs and outputs for daisy-chaining, and powerCON-compatible AC connections for reliable power distribution. The birch plywood construction with steel grilles handles the rigors of mobile use, while high-intensity aluminum suspension hardware enables secure line array mounting.
This system excels in venues holding 200-400 people, outdoor festivals, corporate events, and houses of worship requiring even coverage across wide spaces. The line array design provides consistent sound levels throughout the audience area, reducing hot spots and dead zones common with traditional point-source speakers.
Setup requires standard XLR cables for audio connections and powerCON cables for AC power linking. The package includes an adjustable pole mount (27-45 inches) for flexible positioning. Each component accepts universal 100-240VAC power input.
Seismic Audio backs this system with a one-year warranty and direct factory support. Professional-grade components at a practical price point for serious performers.

Frequently Asked Questions
What size venue does this line array system cover effectively?
This system handles venues with 200-400 people comfortably, including outdoor festivals, wedding receptions, corporate events, and mid-size churches. The line array design provides even coverage across wide areas, while the 18-inch subwoofer ensures bass response reaches the entire audience. For larger venues over 500 people, consider adding additional line array speakers or subwoofers.
What cables do I need to connect this system?
You'll need standard XLR cables to connect your mixer to the subwoofer, then XLR from the subwoofer's output to the line array speaker input for daisy-chaining. For AC power, use powerCON-compatible cables to link the components if desired, though each can also run from separate wall outlets. The system accepts universal 100-240VAC power input.
Can I add more line array speakers to this system later?
Yes, the balanced XLR outputs on both components allow you to daisy-chain additional powered speakers or subwoofers as your venue requirements grow. The powerCON AC outputs also enable power linking for streamlined setup. Many users start with this package and expand by adding more 12-inch line array speakers for wider coverage or additional 18-inch subwoofers for deeper bass.
How does this compare to traditional PA speakers for live sound?
Line array systems like this provide more even sound distribution than traditional point-source PA speakers, reducing volume variations between front and rear audience areas. The vertical line array design projects sound horizontally while controlling vertical dispersion, making it ideal for venues where consistent coverage matters more than raw volume. Traditional PA speakers may be simpler for smaller gigs under 150 people.
Do I need the subwoofer for DJ gigs, or can I use just the line array speaker?
The 12-inch line array speaker extends down to 48Hz, which covers most vocal and instrument fundamentals, but electronic music and hip-hop require the deeper bass extension (35Hz) that only the 18-inch subwoofer provides. For acoustic performances or speaking events, the line array alone may suffice, but for DJ applications with bass-heavy music, the subwoofer is essential for full-range reproduction.
