The FL-15P delivers professional-grade PA sound for bands, DJs, and live sound engineers who need reliable main speakers that can handle demanding gigs. This pair of passive 15" cabinets brings serious power and clarity to medium to large venues without the premium price tag.

Each cabinet puts out 800 watts peak power (400 watts RMS) through a robust 15" woofer paired with a 1.5" titanium compression driver. The 4"x10" horn design ensures consistent coverage across your audience, while the 12/18 dB crossover at 3kHz delivers smooth transitions between low and high frequencies.

Built from 7-ply birch plywood with acoustic damping material, these cabinets are constructed for durability and optimal sound reproduction. The 60Hz to 20kHz frequency response captures everything from deep bass fundamentals to crisp vocal presence. At 98 dB sensitivity and 8-ohm impedance, they work efficiently with most power amplifiers. Dual Speakon and dual 1/4" inputs provide flexible connection options for different amplifier setups.

These speakers handle venues up to 400 people indoors or 250 people for outdoor events. They're built for wedding receptions, club gigs, church services, and corporate events where you need dependable sound reinforcement. The black carpet covering and metal grille stand up to regular transport and setup.

Connect them to your power amplifier using Speakon or 1/4" speaker cables (sold separately). Each cabinet weighs 46 pounds and measures 25.75" x 18.75" x 14.25" with steel recessed handles for easier transport.

Seismic Audio backs these speakers with a one-year warranty and ships them ready to perform out of the box.

Frequently Asked Questions

What size venues can the FL-15P pair handle?

These speakers work well for indoor venues up to 400 people or outdoor events up to 250 people. They're ideal for wedding receptions, small to medium clubs, church services, and corporate events. For larger outdoor festivals or venues over 500 people, you'd want to add subwoofers or step up to a larger line array system.

What amplifier power do I need to drive these speakers?

Each FL-15P cabinet handles 400 watts RMS and 800 watts peak at 8 ohms. You'll want a power amplifier that delivers 400-600 watts per channel at 8 ohms for optimal performance. Popular choices include QSC, Crown, or Yamaha power amps in the 800-1200 watt total range for the pair.

Do I need a subwoofer with the FL-15P speakers?

The 15" woofers provide solid low-end response down to 60Hz, which covers most music without a subwoofer for smaller venues. However, if you're playing EDM, hip-hop, or other bass-heavy music, or if you're covering outdoor areas larger than 200 people, adding a subwoofer like Seismic Audio's 18" subs will give you fuller low-end impact.

What cables do I need to connect these speakers?

You'll need Speakon-to-Speakon or 1/4" to 1/4" speaker cables to connect from your power amplifier to each cabinet. Speakon connections are preferred for higher power applications and provide more secure connections. Make sure to use proper gauge speaker cable - 12 AWG or thicker for runs over 25 feet.

How do these compare to powered PA speakers?

The FL-15P are passive speakers, so you need a separate power amplifier, which gives you more flexibility in amp selection and easier repairs if something fails. Powered speakers have built-in amps but are heavier and more expensive to fix. These passive cabinets let you upgrade your amplifier independently and are generally more reliable for heavy touring use.
