The GH12L pair delivers full-range PA sound for bands, DJs, and venues that need reliable 12-inch speakers without the premium price tag. These passive loudspeakers handle the demanding dynamics of live performance while staying within reach for working musicians and mobile entertainers.

Each cabinet puts out 350 watts RMS (700 watts peak) through a carefully matched driver combination: a high-output 12-inch woofer with pulp ribbed cone and 2-inch copper voice coil, paired with a 1-inch horn tweeter for wide dispersion coverage. The tuned bass reflex enclosure maximizes low-end response while the computer-engineered MDF cabinet keeps resonance in check.

At 8-ohm impedance with 93 dB sensitivity, these speakers work efficiently with most power amplifiers and can be daisy-chained for larger setups. The 50 Hz to 20 kHz frequency response covers everything from kick drums to vocal clarity, making them versatile mains for bands or DJ setups.

These speakers handle venues up to 200 people indoors or 150 outdoors, perfect for club gigs, church sound systems, school events, and mobile DJ work. The road-ready construction includes heavy-duty ABS handles, impact-resistant corner guards, and steel mesh grilles to survive regular transport and setup.

Connect via standard 1/4-inch TS inputs or raw speaker wire terminals - dual parallel inputs on each cabinet make daisy-chaining simple. You'll need speaker cables and a compatible power amplifier (sold separately).

Backed by Seismic Audio's one-year warranty with fast shipping. Professional-grade components at a price that works for real-world budgets.

Frequently Asked Questions

What size venues can the GH12L pair handle?

These speakers work well for indoor venues up to 200 people or outdoor events up to 150 people. They're ideal for club gigs, wedding receptions, church services, and school events where you need full-range sound coverage. For larger venues or outdoor festivals, consider adding a subwoofer or using multiple pairs.

What amplifier power do I need to drive these speakers?

Each GH12L handles 350 watts RMS, so you'll want an amplifier that provides 300-400 watts per channel at 8 ohms for optimal performance. Popular choices include Crown XTi series, QSC GX series, or Yamaha P series power amplifiers. Make sure your amp can handle the 8-ohm load.

Can I daisy-chain multiple GH12L speakers together?

Yes, each speaker has dual parallel inputs specifically designed for daisy-chaining. At 8 ohms each, you can connect two speakers per amplifier channel (resulting in a 4-ohm load) safely with most professional power amplifiers. Use standard speaker cable with 1/4-inch TS connectors or bare wire connections.

Do I need a subwoofer with the GH12L speakers?

The GH12L covers bass frequencies down to 50 Hz, which handles most music well for small to medium venues. However, if you're playing bass-heavy electronic music, hip-hop, or want more punch for dance events, adding a subwoofer like Seismic Audio's 15-inch or 18-inch models will give you deeper low-end extension and more impact.

How do these compare to active speakers in the same price range?

The GH12L passive speakers give you more flexibility in amplifier choice and easier serviceability if components fail. You'll need to purchase a separate power amplifier, which adds cost but lets you upgrade power later or use one amp for multiple speaker pairs. Active speakers are more convenient for plug-and-play setups but limit your amplification options.
