The Apex-12D column line array system delivers professional-grade sound for bands, DJs, and venues that need powerful, portable PA coverage without the bulk of traditional speaker setups. This complete system combines a 500-watt RMS active 12" subwoofer with two 300-watt RMS column speakers, each housing four 4" drivers for controlled directional coverage.

The column design provides even sound distribution across your audience while minimizing feedback issues that plague traditional wedge monitors. With 1600 watts peak system power and 123dB maximum SPL, this system handles everything from acoustic sets to high-energy dance music with authority.

Built-in Bluetooth 4.2 connectivity lets you stream music wirelessly, while the comprehensive input panel accepts microphones, instruments, and line sources through combo XLR/TRS jacks, RCA inputs, and a 3.5mm aux connection. The integrated DSP with 96kHz sampling provides multiple EQ presets to optimize sound for different venues and applications.

This system works perfectly for small to medium venues up to 300 people, corporate events, wedding receptions, and mobile DJ setups where quick deployment and professional appearance matter. The columns mount securely on included speaker stands, and the entire system breaks down efficiently for transport.

All connections between the subwoofer and column speakers use professional Speakon connectors for secure, reliable signal transfer. The system includes everything needed for immediate deployment: subwoofer, two column speakers, and a pair of speaker stands.

Seismic Audio backs the Apex-12D with comprehensive warranty coverage and fast shipping, giving you professional column array performance at a price point that makes sense for working musicians and mobile entertainers.

Frequently Asked Questions

What size venues can the Apex-12D column array system handle?

The Apex-12D is designed for small to medium venues accommodating up to 300 people. With 1600 watts peak power and 123dB maximum SPL, it provides sufficient coverage for wedding receptions, corporate events, small clubs, and outdoor gatherings. The column design ensures even sound distribution across the audience area while maintaining clarity at various listening positions.

What cables do I need to connect the Apex-12D system?

The system uses Speakon cables to connect the column speakers to the subwoofer, and these connections are typically included with the system. For audio sources, you can connect directly using XLR, TRS, or RCA cables depending on your mixer or audio source. The system also accepts wireless audio via built-in Bluetooth 4.2, eliminating the need for cables when streaming music from mobile devices.

Can I use the column speakers without the subwoofer?

Yes, the column speakers can operate as full-range speakers without the subwoofer engaged. This flexibility allows you to use just the columns for acoustic performances, speaking events, or situations where deep bass isn't needed. Each column speaker delivers 300 watts RMS and covers the frequency range needed for vocals and most instruments when used independently.

How does the column design compare to traditional PA speakers?

Column arrays like the Apex-12D provide more controlled sound dispersion than traditional box speakers, reducing feedback issues and delivering more even coverage across your audience. The narrow vertical dispersion pattern minimizes sound reflections from ceilings and floors, while the wide horizontal coverage ensures everyone in your audience hears consistent sound quality regardless of their position.

What DSP features are included with the Apex-12D?

The built-in DSP operates at 96kHz sampling frequency with 48-bit processing and includes multiple preset modes optimized for different applications. You can adjust these settings using the onboard controls, which include volume controls for left, right, and subwoofer channels, plus DSP mode selection, phase reverse, and stereo/mono switching. The system also includes protection circuits for short circuit, over-current, limiting, and thermal management.
