The FL-155PC is built for bands, DJs, and venues that need serious sound reinforcement without the back-breaking setup. This dual 15" PA cabinet combines professional power handling with mobility features designed for real-world gigging.

Each cabinet delivers 800 watts RMS (1600 watts peak) through dual 15" woofers paired with a 1.5" titanium compression driver. The result is full-range coverage from 50 Hz to 20 kHz with the headroom needed for dynamic live performances.

The dual 15" configuration with 80 oz magnet woofers and 3" voice coils provides the low-end punch that single-driver cabinets can't match. The titanium horn driver handles highs with precision, while the 12/18 dB crossover at 3 kHz includes dual glass bulb tweeter protection. At 4 ohms impedance and 100 dB sensitivity, these cabinets work efficiently with most power amplifiers.

This speaker handles medium to large venues — think club gigs for 200-400 people, outdoor festivals, or church sanctuaries. The rear-mounted wheel kit and handle system makes transport manageable for a 67-pound dual-15 cabinet. Four ports provide proper bass tuning, while the 7-ply birch plywood construction ensures durability on the road.

Connect via dual 1/4" or Speakon inputs. Standard speaker cables work with most amplifiers or powered mixers.

Seismic Audio backs every FL-155PC with a one-year warranty. Professional-grade components, gigging-friendly design, accessible pricing.

Frequently Asked Questions

What size venues can the FL-155PC handle?

These dual 15" cabinets are designed for medium to large venues with 200-400 people. The 800-watt RMS power handling and dual-driver configuration provide enough headroom for live bands in clubs, outdoor events, or church sanctuaries. For smaller venues under 150 people, you might find this cabinet provides more power than needed.

What amplifier power do I need for the FL-155PC?

With 4-ohm impedance and 100 dB sensitivity, these cabinets work efficiently with amplifiers from 400-800 watts RMS per channel. You can use less powerful amps for smaller venues, but having the full 800 watts available ensures you won't clip the amplifier during dynamic peaks in live music.

Do I need a subwoofer with these speakers?

The dual 15" woofers provide substantial low-end response down to 50 Hz, making external subwoofers optional for most live sound applications. However, DJs playing bass-heavy electronic music or bands wanting extra low-end impact may still benefit from adding dedicated subwoofers, especially in larger venues.

What cables do I need to connect the FL-155PC?

You can use either 1/4" speaker cables or Speakon cables — each cabinet has both input types. Speakon connections are preferred for professional applications as they lock securely and handle high power better. Never use instrument cables or XLR cables, which aren't designed for speaker-level signals.

How portable is a 67-pound dual 15" cabinet?

The rear-mounted wheel kit and handle system make transport much easier than traditional dual-15 cabinets. You can roll the cabinet like luggage rather than lifting the full weight. The wheels handle loading docks, parking lots, and most venue floors, though you'll still need to lift for stairs or elevated stages.
