This concert PA package delivers serious sound reinforcement for live venues, festivals, and touring acts that need professional-grade output without the premium price tag. The system combines dual 15-inch main speakers with dedicated 18-inch subwoofers to cover the full frequency spectrum at high SPL levels.

Each main cabinet houses two 15-inch woofers and a 1.5-inch titanium tweeter, handling 700 watts RMS and 1400 watts peak power. The dual-driver configuration provides increased headroom and better sound dispersion across larger crowds. The companion 18-inch subwoofers feature down-firing designs with 90-ounce magnets and 3-inch voice coils, delivering 500 watts RMS and 1000 watts peak power per cabinet.

This four-piece system handles mid to large venues effectively, supporting crowds from 500 to 1,500 people depending on your amplifier selection and venue acoustics. The setup works well for rock concerts, festivals, corporate events, and permanent installations where deep bass response is essential. The main speakers provide clear vocal reproduction and instrument definition, while the subwoofers extend the low-end response for modern music genres.

Standard 1/4-inch and Speakon connections accommodate most professional amplifiers and crossover systems. You'll need separate amplification and a crossover to properly drive this passive system.

All cabinets ship free within the continental US and come backed by Seismic Audio's standard warranty and technical support.

Frequently Asked Questions

What size venue can this PA package handle?

This system effectively covers venues with 500 to 1,500 people, depending on your amplifier power and venue acoustics. The dual 15-inch mains provide excellent projection for outdoor festivals and large indoor spaces, while the 18-inch subwoofers ensure adequate bass response for modern music. For smaller clubs under 300 people, this system may be overpowered.

Do I need separate amplifiers for the mains and subwoofers?

Yes, this is a passive system requiring external amplification. You'll need at least two stereo amplifiers or four mono amps to properly drive all four cabinets. Most users also add an active crossover or DSP unit to split frequencies between the mains and subs, typically crossing over around 80-120Hz for optimal performance.

How does this compare to powered PA systems?

Passive systems like this offer more flexibility in amplifier selection and easier serviceability, but require additional equipment and setup time. Powered systems are more convenient but limit your amplifier choices. This passive approach is preferred by sound engineers who want to match specific amplifiers to their venue requirements and musical content.

What cables do I need to connect this system?

You'll need speaker cables with 1/4-inch or Speakon connectors to run from your amplifiers to each cabinet. Plan for at least 25-50 feet of cable per cabinet depending on your stage setup. If using a crossover, you'll also need audio cables to connect your mixer to the crossover unit.

Can I add more subwoofers to this system later?

Yes, you can expand the low-end by adding more 18-inch subwoofers as your venues grow. Many users start with this 2+2 configuration and add additional subs for larger outdoor events. Just ensure your amplifiers can handle the additional impedance load when connecting multiple cabinets.
