The Apex-12Sub delivers professional bass reinforcement for DJs, bands, churches, and mobile performers who need deep low-end punch without the bulk of larger subwoofers. This powered 12" subwoofer handles the foundational frequencies that standard PA speakers can't reproduce, completing your sound system with rich, controlled bass.

Built around a 12" woofer driven by 500 watts RMS of Class D power, the Apex-12Sub produces clean bass down to 45Hz with a maximum SPL of 123dB peak. The integrated DSP processor with 96KHz sampling ensures tight, musical bass response whether you're running recorded tracks or live instruments. Built-in Bluetooth 4.2 connectivity lets you stream audio wirelessly, while variable-speed cooling fans maintain consistent performance during extended use.

This compact subwoofer works perfectly for venues up to 200-300 people, from church worship services and wedding receptions to club gigs and outdoor events. The multiple input options—XLR/TRS combo jacks, RCA inputs, and 3.5mm aux—accommodate any source, while the onboard mixer controls let you balance subwoofer levels with your main speakers.

Connect your mixer or audio source using standard XLR or RCA cables. The Apex-12Sub can also function as part of the larger Apex-12D column array system for expanded coverage. At 62 pounds and measuring 27.75" x 22" x 25.50", it's portable enough for mobile setups yet substantial enough for permanent installations.

Seismic Audio backs the Apex-12Sub with fast shipping and reliable customer support, giving you professional bass performance at a practical price point.

Frequently Asked Questions

What size venues can the Apex-12Sub handle?

The Apex-12Sub is designed for small to medium venues accommodating up to 200-300 people. This makes it ideal for church services, wedding receptions, club gigs, corporate events, and outdoor gatherings. The 500-watt RMS power and 123dB peak SPL provide sufficient bass reinforcement for these spaces without overwhelming smaller rooms or requiring excessive volume levels.

What cables do I need to connect the Apex-12Sub to my mixer?

You can connect the Apex-12Sub using standard XLR cables, TRS cables, or RCA cables depending on your mixer's outputs. The subwoofer features both XLR and combo jack inputs for professional mixers, plus RCA inputs for DJ mixers or consumer equipment. A 3.5mm aux input is also available for direct connection to phones or laptops.

Can I use the Apex-12Sub without other speakers?

While the Apex-12Sub produces frequencies from 45Hz-19KHz, it's designed primarily as a subwoofer for bass reinforcement rather than a full-range speaker. For complete sound coverage, pair it with main PA speakers or monitors that handle mid and high frequencies. The onboard controls let you balance the subwoofer level with your main speakers for optimal sound.

Does the Bluetooth connection work for live performances?

Yes, the built-in Bluetooth 4.2 provides stereo wireless connectivity suitable for background music, announcements, or DJ sets where slight latency isn't critical. For live music performance where timing is essential, use the wired XLR or combo jack inputs instead. The Bluetooth feature excels for pre-show music, breaks between sets, or events where wireless convenience is prioritized.

How does this compare to larger 15" or 18" subwoofers?

The Apex-12Sub offers a more compact and portable solution while still delivering solid bass response down to 45Hz. Larger subwoofers like 15" or 18" models produce deeper bass and higher SPL levels, making them better for larger venues or bass-heavy music genres. The 12" size strikes a balance between portability and performance, making it perfect for mobile setups where transport and setup ease matter as much as sound quality.
