Seismic Audio GH-15L - Pair of Passive 15 Inch 2-Way PA/DJ Loudspeaker Cabinets - 800 Watt each Full Range PA/DJ Band Live Sound Speakers

When you need a pair of mains that won't let you down at club gigs, wedding receptions, or church services, the GH-15L speakers deliver straightforward PA performance without the boutique price tag. These passive 15-inch two-ways handle 400 watts RMS each and push enough sound for indoor venues up to 200 people — that sweet spot where most working musicians spend their weekends.

The 15-inch woofers give you the low-end punch you need for kick drums and bass guitar, while the 1-inch horn tweeters spread vocals and cymbals evenly across your audience. At 97 dB sensitivity, they'll get plenty loud with a modest power amp, and the 8-ohm impedance makes daisy-chaining dead simple when you need to expand your rig.

What you're getting here is a workhorse PA system that connects to any power amplifier or powered mixer via standard speaker cables. The MDF cabinets have bass-reflex ports for enhanced low-end response, ABS corner guards to survive the van, and steel mesh grilles that actually protect the drivers. At 36 pounds per cabinet, they're manageable for one-person load-ins, though you'll appreciate having a cart for longer hauls.

These aren't trying to be studio monitors or high-end install speakers — they're built for the gigging musician who needs reliable mains that sound good and show up to work every night. The frequency response runs 50 Hz to 20 kHz, which covers everything you'll throw at them for live sound applications.

Bottom line: If you need a solid pair of 15-inch mains for mid-size venues and you already have an amp, the GH-15L speakers will handle your gigs without drama or breaking your budget.

Frequently Asked Questions

What size venues can these handle?

You're looking at indoor venues up to 200 people — clubs, wedding halls, fellowship halls, small theaters. For outdoor gigs, figure 100-150 people since you lose the room's reflective surfaces. The 97 dB sensitivity and 400-watt power handling give you enough headroom for most live sound situations where people actually want to have conversations.

What amp power do I need?

Match these with 300-600 watts per channel at 8 ohms. This gives you clean headroom without cooking the 400-watt RMS drivers. Crown XLi series, QSC GX series, or any powered mixer with decent output will do the job. Don't underpower them — weak amps cause more speaker damage than strong ones.

Can I daisy-chain multiple speakers?

Yes, the 8-ohm impedance and dual inputs make chaining straightforward. You can run two pairs (four speakers total) off a single stereo amp channel, which drops the load to 4 ohms. Just make sure your amp is stable at 4 ohms before you wire it up.

Do I need subs with these?

For most gigs, the 15s handle bass down to 50 Hz just fine. Add a sub if you're doing hip-hop, EDM, or large outdoor events where you need that extra low-end extension. The bass-reflex design already gives you more bottom than sealed cabinets.
