The FL-15P delivers professional PA sound for bands, DJs, and venues that need reliable 15-inch performance without the premium price tag. This passive speaker cabinet handles 400 watts RMS and 800 watts peak power, making it a solid choice for live sound reinforcement and DJ setups.

The 15-inch woofer with 80 oz magnet and 3-inch voice coil provides the low-end punch you need, while the 1.5-inch titanium tweeter driver cuts through the mix with clarity. The 4x10-inch horn design ensures consistent coverage across your audience.

Built with 7-ply birch plywood construction, this cabinet delivers durability that touring professionals demand. The crossover operates at 3 kHz with 12/18 dB per octave slopes and includes dual glass bulb tweeter protection. At 98 dB sensitivity and 8-ohm impedance, it pairs efficiently with most power amplifiers. The frequency response spans 60 Hz to 20 kHz, covering the full range of musical content.

This speaker works well for bands playing clubs and small theaters, DJ gigs for weddings and corporate events, or as the main PA for venues accommodating 200-300 people. For outdoor events, expect to cover about half that capacity effectively.

Connect via dual 1/4-inch or dual Speakon inputs using standard speaker cables. The cabinet includes steel recessed handles, metal grille protection, and black carpet covering for professional appearance and roadworthy durability.

Seismic Audio backs every FL-15P with a one-year warranty and ships direct from our warehouse to get you performing faster.

Frequently Asked Questions

What size venues can the FL-15P handle?

The FL-15P works well for indoor venues accommodating 200-300 people, such as clubs, small theaters, wedding receptions, and church sanctuaries. For outdoor events where sound disperses more freely, expect effective coverage for about 100-150 people. The 98 dB sensitivity and 400-watt RMS power handling provide sufficient headroom for most live band and DJ applications in these sized spaces.

Do I need a subwoofer with this 15-inch speaker?

For most applications, the FL-15P's 15-inch woofer provides adequate low-end response down to 60 Hz. However, if you're playing bass-heavy music like hip-hop, EDM, or contemporary worship with synthesized bass, adding a subwoofer will enhance the full-range experience. The speaker works well on its own for rock, country, jazz, and acoustic performances where natural bass response is sufficient.

What cables and amplifier do I need?

You'll need speaker cables with 1/4-inch or Speakon connectors to connect from your power amplifier. The 8-ohm impedance works with most professional power amplifiers - aim for an amp rated between 300-600 watts at 8 ohms for optimal performance. Standard 12-gauge or 14-gauge speaker cable works fine for runs up to 50 feet.

Can I use this as a floor monitor?

Yes, the FL-15P works as a floor monitor for musicians who need to hear themselves on stage. The angled cabinet design and horn dispersion pattern provide good coverage when placed on the floor pointing up toward the performer. The dual input connectors make it easy to daisy-chain multiple monitors from a single amplifier channel.

How does the birch plywood construction compare to other materials?

The 7-ply birch plywood cabinet construction offers better acoustic properties and durability compared to particle board or MDF alternatives. Birch plywood provides superior strength-to-weight ratio, better resonance control, and increased longevity for touring applications. The acoustic damping material inside further reduces unwanted vibrations, resulting in cleaner sound reproduction across the frequency range.
