The GH28L pair delivers professional-grade live sound for bands, DJs, and venues that need reliable main speakers without the premium price tag. Each cabinet features dual 8-inch woofers and a 1-inch horn tweeter in a compact, roadworthy design that fits tight stages and mobile setups.

These passive PA speakers handle 450 watts RMS and peak at 900 watts per cabinet, providing the headroom you need for dynamic performances. The dual 8-inch configuration delivers fuller midrange than single-driver designs while maintaining clarity through the wide-dispersion horn tweeter.

Built around computer-engineered MDF enclosures with tuned bass reflex ports, the GH28L maximizes low-end response from its 8-inch drivers. At 4-ohm impedance with 93 dB sensitivity, these speakers work efficiently with most power amplifiers. The 50 Hz to 20 kHz frequency response covers the full spectrum for music and vocals.

Each 26-pound cabinet handles small to medium venues up to 200 people indoors, making them ideal for band rehearsals, church services, DJ gigs, and school events. The rugged carpet covering and steel mesh grilles protect against transport damage and stage mishaps.

Connect via 1/4-inch TS jacks or binding post terminals to your amplifier or powered mixer. Each cabinet includes recessed handles for easy transport.

Seismic Audio backs the GH28L pair with a one-year warranty and ships fast from our warehouse. Professional sound that fits your budget and your van.

Frequently Asked Questions

What size venues can the GH28L pair handle?

These speakers work well for small to medium venues up to 200 people indoors, such as churches, school auditoriums, rehearsal spaces, and club gigs. For outdoor events, expect effective coverage for crowds up to 150 people. The dual 8-inch configuration provides more midrange punch than single-driver alternatives in this power range.

What amplifier power do I need for the GH28L speakers?

Each GH28L cabinet handles 450 watts RMS at 4 ohms, so you'll want an amplifier that delivers at least 450 watts per channel into 4 ohms for full power. A stereo amplifier rated for 500-600 watts per channel into 4 ohms gives you clean headroom. The 93 dB sensitivity means they'll get plenty loud with moderate amplifier power.

What cables do I need to connect these speakers?

You'll need speaker cables from your amplifier to each GH28L cabinet. Use 1/4-inch TS to 1/4-inch TS speaker cables, or connect directly to the binding post terminals with bare wire or banana plugs. For most setups, 14-gauge speaker cable works fine for runs under 50 feet.

Do I need a subwoofer with the GH28L pair?

The dual 8-inch woofers provide solid bass response down to 50 Hz, which covers most music and vocal applications without a subwoofer. However, if you're doing DJ work with electronic music or want more low-end impact for larger venues, adding a powered subwoofer will enhance the full-range experience and let you push the mains harder.

How do these compare to powered speakers in this price range?

The GH28L gives you more flexibility since you can choose your own amplifier and upgrade power later without replacing the cabinets. Passive speakers also tend to be more reliable for mobile use since there are fewer electronics to fail. However, you'll need to factor in amplifier cost and the extra cable run from amp to speakers.
