The GH28L delivers serious mid-range punch for DJs, bands, and venues that need more vocal clarity and presence than single-driver speakers can provide. Dual 8-inch woofers paired with a wide-dispersion horn tweeter create the kind of balanced sound that cuts through ambient noise and keeps audiences engaged.

This passive 2-way speaker handles 450 watts RMS and peaks at 900 watts, giving you the headroom needed for dynamic live performances. The dual-woofer configuration provides fuller low-mid response than typical single 8-inch designs, while the horn-loaded tweeter ensures vocals and lead instruments project clearly across the room.

At 4 ohms impedance with 93 dB sensitivity, the GH28L pairs efficiently with most power amplifiers and delivers strong output without requiring excessive amplifier power. The computer-engineered MDF cabinet features bass reflex tuning to extend low-frequency response down to 50 Hz, while aviation-grade carpet covering and steel mesh grilles protect the drivers during transport and setup.

Perfect for bands playing clubs and small venues, mobile DJs working private parties up to 150 people, or houses of worship seeking clear vocal reproduction for congregations of similar size. The dual 8-inch design makes these speakers particularly effective as stage monitors where musicians need to hear both vocals and instruments clearly.

Connect via standard 1/4-inch TS cables or direct speaker wire to your amplifier. Recessed handles make transport manageable at 26 pounds per cabinet.

Seismic Audio backs the GH28L with a full one-year warranty and ships factory-direct to keep your live sound system budget in check.

Frequently Asked Questions

What size venue can the GH28L handle?

The GH28L works well for indoor venues up to 150 people, such as small clubs, private parties, and worship spaces. The dual 8-inch configuration provides more vocal clarity and mid-range presence than single-driver speakers, making it effective for audiences that need to clearly hear speech and lead vocals. For outdoor events, expect coverage for about 100 people due to the lack of wall reflections.

What amplifier power do I need for the GH28L?

You'll want an amplifier rated for 450-600 watts RMS into 4 ohms to properly drive the GH28L at full capacity. The speaker's 93 dB sensitivity means it doesn't require massive amplifier power to get loud, but having adequate headroom ensures clean sound during dynamic peaks. Most professional power amplifiers in the 500-800 watt range work well with this speaker.

Do I need a subwoofer with the GH28L?

For most applications, the dual 8-inch woofers provide sufficient low-end response down to 50 Hz, especially for vocal-focused events like worship services or acoustic performances. However, if you're playing bass-heavy music like hip-hop or EDM, adding a subwoofer will give you the deep bass extension and impact that 8-inch drivers can't fully reproduce. The choice depends on your musical content and venue acoustics.

What cables do I need to connect the GH28L?

You can connect using standard 1/4-inch TS (tip-sleeve) speaker cables from your amplifier's speaker outputs to the GH28L's input jacks. Alternatively, you can use raw speaker wire connected directly to the binding post terminals. Never use instrument cables or XLR cables for this connection – only proper speaker cables rated for the power output of your amplifier.

How does the dual 8-inch design compare to a single 12-inch speaker?

The dual 8-inch configuration typically provides better vocal clarity and mid-range definition than a single 12-inch driver, making it ideal for applications where speech intelligibility matters most. A single 12-inch speaker usually delivers more low-end punch and overall volume, but may not articulate vocals as clearly. Choose the GH28L when vocal presence is your priority over maximum bass output.
