The FL-155PC delivers serious sound reinforcement for bands, DJs, and venues that need dual 15" power with professional mobility features. Each cabinet combines two 15" woofers with a titanium compression driver to handle everything from live rock shows to corporate events.

These passive PA speakers push 800 watts RMS and 1600 watts peak per cabinet, giving you the headroom needed for dynamic live sound. The dual 15" configuration with 4-port venting delivers deep bass response while the 1.5" titanium horn handles crisp highs across the full 50 Hz to 20 kHz range.

Built from 7-ply birch plywood with acoustic damping material, each cabinet weighs 66.8 pounds but includes rear handles and wheel kits for easier transport. The 4-ohm impedance and 100 dB sensitivity work efficiently with most power amplifiers. The 12/18 dB crossover at 3 kHz includes dual glass bulb tweeter protection to prevent driver damage.

Perfect for bands playing clubs and outdoor festivals, mobile DJs covering weddings and corporate events, or churches and schools needing powerful main PA speakers. Each cabinet handles venues up to 400 people indoors or 250 people outdoors when properly amplified.

Connect via dual 1/4" inputs or dual Speakon connectors to your power amplifier or powered mixer. The black carpeted finish with full metal grille stands up to regular transport and setup.

Seismic Audio backs each pair with a one-year warranty and ships from our warehouse within one business day.

Frequently Asked Questions

How many people can these dual 15" speakers cover?

Each FL-155PC cabinet handles up to 400 people indoors or 250 people outdoors when properly amplified. For larger venues, you can run multiple pairs or add subwoofers for additional low-end reinforcement. The dual 15" configuration provides excellent coverage for medium to large spaces.

What amplifier power do I need for these speakers?

These 4-ohm cabinets work best with amplifiers delivering 400-800 watts RMS per channel. You can safely use up to 1600 watts peak power per cabinet. Most professional power amplifiers or powered mixers in the 500-1000 watt range will drive these speakers effectively.

Do the wheel kits and handles make transport easier?

Yes, each cabinet includes built-in wheel kits and rear handles specifically designed for the 66.8-pound weight. The wheels let you roll the speakers instead of lifting them, while the rear handles provide secure grip points for loading and positioning. This makes solo setup much more manageable.

Can I connect these directly to a mixer without an amplifier?

No, these are passive speakers that require a separate power amplifier. You'll need to connect your mixer to a power amplifier, then run speaker cables from the amplifier to these cabinets using either 1/4" or Speakon connections. This gives you more flexibility in amplifier choice and system expansion.

How do these compare to single 15" speakers for live sound?

The dual 15" design provides significantly more bass response and overall volume than single 15" cabinets. You get better low-end extension and higher SPL capability, making these better suited for rock bands, large venues, or any application where you need serious low-frequency impact without adding separate subwoofers.
