Powered Line Array System - 18 Inch Subwoofer, Two 12 Inch Line Array Speakers and Mounting Frame

$4,399.99 $7,279.99

This powered line array system is built for touring bands, rental companies, and permanent installations that need professional sound reinforcement with the clarity and throw of true line array technology. The complete package includes an 18-inch powered subwoofer, two 12-inch powered line array speakers, and the mounting frame to deploy them as a cohesive system.

The line array speakers deliver focused, long-throw coverage that maintains consistent sound levels throughout your venue, while the dedicated subwoofer handles low-end reinforcement from 35Hz up to 300Hz. Each 12-inch speaker produces 300 watts RMS (600 watts peak) with dual 1-inch titanium compression drivers, while the 18-inch sub delivers 600 watts RMS (1200 watts peak) for substantial bass impact.

The system operates at 8 ohms impedance with frequency response from 35Hz to 20kHz across all components. Maximum SPL reaches 130dB per speaker, providing the headroom needed for demanding live sound applications. Each component features Class AB amplification with cooling fans and universal 100-240V power supplies for reliable operation.

This configuration handles outdoor festivals, large churches, concert venues, and corporate events for crowds up to 800 people, depending on venue acoustics and coverage requirements. The line array design provides even coverage across long distances while minimizing sound spillover to adjacent areas.

All speakers feature balanced XLR inputs and outputs with powerCON-compatible connectors for daisy-chaining power and signal. The 12-inch speakers also include combo XLR/quarter-inch inputs for mixer flexibility. Each component is housed in birch plywood enclosures with steel grilles and aluminum suspension hardware.

Seismic Audio backs this system with a one-year warranty and ships everything needed to get your line array operational immediately.

Frequently Asked Questions

What size venues can this line array system handle?

This system is designed for medium to large venues accommodating 400-800 people, depending on the space and coverage requirements. The line array configuration provides excellent long-throw performance for outdoor festivals, large churches, concert halls, and corporate events. For smaller venues under 200 people, traditional point-source speakers may be more appropriate.

What cables do I need to connect this line array system?

You'll need balanced XLR cables to connect your mixer to the subwoofer input, then from the subwoofer's XLR output to the first line array speaker, and between the two line array speakers. Each powered component requires a power connection using the included powerCON-compatible connectors, which can be daisy-chained to reduce the number of AC outlets needed.

How do I mount the line array speakers with the included frame?

The included mounting frame allows you to stack and angle the two 12-inch line array speakers for optimal coverage pattern. The frame uses high-intensity aluminum suspension hardware and connects to the speakers' built-in rigging points. The subwoofer is typically ground-stacked separately and includes a pole mount cup for additional positioning options.

Do I need additional processing or can I run this system directly from my mixer?

This powered line array system includes built-in amplification and basic processing, so you can connect directly from your mixer's main outputs. The subwoofer handles the crossover duties, sending full-range signal to the line array speakers while processing the low frequencies internally. No external amplifiers, crossovers, or DSP units are required for basic operation.

How does this compare to using multiple point-source speakers?

Line array systems like this provide more even coverage across long distances and better control over vertical dispersion compared to multiple point-source speakers. This results in more consistent sound levels from front to back of your venue and reduced sound spillage to unwanted areas. However, point-source systems offer more flexibility for smaller venues or situations where you need to cover multiple zones independently.
