The GH-15L pair delivers full-range PA sound for bands, DJs, and live performers who need reliable mains that handle mid-size venues without breaking the budget. These passive 15-inch speakers work with any power amp or powered mixer to build a complete PA system.

Each cabinet pushes 400 watts RMS (800 watts peak) through a 15-inch woofer and 1-inch horn tweeter, covering 50 Hz to 20 kHz with 97 dB sensitivity. The two-way design handles vocals, instruments, and backing tracks with enough output for venues up to 200 people indoors.

The 8-ohm impedance makes daisy-chaining simple when you need to expand your system. Dual inputs accept 1/4-inch connections or raw speaker wire from your amp. The bass-reflex cabinet design enhances low-end response, while the wide-dispersion horn tweeter ensures even coverage across your audience.

Perfect for club gigs, wedding receptions, church services, and school events where you control the power amp and mixing. The MDF construction with ABS corner guards and steel mesh grilles handles the road, while carry handles make load-in manageable at 36 pounds per cabinet.

Connect these speakers to any power amplifier or powered mixer using standard speaker cables. Each cabinet includes dual input terminals for easy daisy-chaining to additional speakers.

Seismic Audio backs the GH-15L pair with a one-year warranty and ships direct to keep professional sound accessible for working musicians and mobile performers.

Frequently Asked Questions

What size venues can the GH-15L pair handle?

These speakers work well for indoor venues up to 200 people, such as clubs, wedding halls, small theaters, and fellowship halls. For outdoor events, expect effective coverage for about 100-150 people due to the lack of reflective surfaces. The 97 dB sensitivity and 400-watt RMS power handling provide enough volume for most mid-size live sound applications.

What amplifier power do I need for these speakers?

Match these speakers with an amplifier that delivers 300-600 watts per channel at 8 ohms. This gives you clean headroom without risking damage to the 400-watt RMS speakers. Popular choices include Crown XLi series, QSC GX series, or any powered mixer with sufficient output power.

Can I daisy-chain multiple GH-15L speakers together?

Yes, the 8-ohm impedance and dual input terminals make daisy-chaining straightforward. You can connect two pairs (four total speakers) to a single stereo amplifier channel, which presents a 4-ohm load. Always check that your amplifier can handle the combined impedance load safely.

Do I need a subwoofer with the GH-15L speakers?

For most applications, the 15-inch woofers provide adequate bass response down to 50 Hz. Add a subwoofer if you're playing bass-heavy music like hip-hop or electronic dance music, or if you're covering large outdoor areas. The bass-reflex design already enhances the low-end output compared to sealed cabinets.

What cables do I need to connect these speakers?

Use standard speaker cables with 1/4-inch TS plugs or bare wire connections. For typical stage setups, 25-50 foot speaker cables work well. Avoid instrument cables, which aren't designed for speaker-level signals and can cause poor performance or equipment damage.
