The GH12L delivers professional-grade live sound for bands, DJs, and venues that need reliable PA performance without the premium price. This passive 12-inch two-way speaker handles the demanding dynamics of live music and DJ sets with robust power handling and wide dispersion coverage.

Built around a high-output 12-inch woofer with pulp ribbed cone and multi-layer copper voice coil, the GH12L reproduces everything from deep bass lines to crisp vocals. The 1-inch horn tweeter with 75-watt capacity ensures clear highs that cut through stage volume, while the tuned bass reflex enclosure maximizes low-end impact without muddiness.

With 350 watts RMS and 700 watts peak power handling at 8 ohms, this speaker drives loud and clean through most any amplifier setup. The 93 dB sensitivity rating means you get serious volume without needing massive amplifier power. Frequency response spans 50 Hz to 20 kHz, covering the full spectrum of modern music with authority.

Perfect for small to medium venues up to 200 people, band rehearsals, mobile DJ gigs, and church sound systems. The computer-engineered MDF cabinet features heavy-duty ABS handles and corner guards that survive the rigors of regular transport and setup.

Connect via standard 1/4-inch TS inputs or speaker wire terminals, making integration with any amplifier or mixer straightforward. Dual parallel inputs allow easy daisy-chaining for multi-speaker setups.

Backed by Seismic Audio's one-year warranty and direct-from-manufacturer pricing that puts professional sound within reach of working musicians and mobile entertainers.

Frequently Asked Questions

How many people can the GH12L cover for live sound?

The GH12L effectively covers venues up to 200 people for live music or DJ applications. For outdoor events, expect coverage for 100-150 people due to the lack of wall reflections. A pair of GH12L speakers can handle larger indoor venues up to 300 people when properly positioned and powered with adequate amplification.

What amplifier power do I need to drive the GH12L properly?

You'll want an amplifier delivering 250-400 watts RMS at 8 ohms to properly drive the GH12L without underpowering or clipping. The speaker's 93 dB sensitivity means it produces good volume even with moderate amplifier power, but having adequate headroom ensures clean sound at higher volumes. Avoid amplifiers exceeding 700 watts to prevent driver damage.

Can I daisy chain multiple GH12L speakers together?

Yes, the dual parallel inputs make daisy chaining straightforward using standard speaker cables. Each GH12L presents an 8-ohm load, so two speakers create a 4-ohm load, and four speakers create a 2-ohm load. Make sure your amplifier is rated to handle the combined impedance load of your speaker configuration safely.

Do I need a subwoofer with the GH12L for full-range sound?

The GH12L's 50 Hz low-frequency response handles most music content well on its own, including kick drums and bass guitar fundamentals. For EDM, hip-hop, or applications requiring deep sub-bass extension below 50 Hz, adding a subwoofer enhances the low-end impact. For rock bands and most live music, the GH12L provides sufficient bass response as a standalone speaker.

What cables do I need to connect the GH12L to my mixer or amplifier?

You'll need standard speaker cables with 1/4-inch TS plugs or bare wire connections, depending on your amplifier outputs. Never use instrument cables or XLR cables for speaker connections. If running long distances, use 12 or 14-gauge speaker cable to maintain power transfer and prevent signal loss. The parallel inputs allow you to run one cable in and daisy chain to additional speakers.
