Name: 18 LFA 1400 V2
Brand: POWERX PRO
Availability: InStock

The 18 LFA 1400 V2 is an elite 18-inch low-frequency transducer belonging to the acclaimed PRO SERIES. Designed to serve as a premier acoustic engine, this speaker driver provides the perfect backbone for demanding live sound subwoofers and permanent stage monitoring setups.

Prioritizing immense acoustic output, it handles a continuous 1400 AES Watts with a peak maximum power capability of 2800 Watts. Supported by a strong sensitivity of 98 dB (1W/1M), this transducer offers the dynamic headroom required to push serious overall loudness without sacrificing clarity at peak performance levels.

Driver technology is anchored by an oversized 101.6 mm (4.5-inch) voice coil paired with a heavy-duty Ferrite magnet structure. Utilizing a high-quality paper cone, the internal acoustics are optimized to deliver phase-accurate, hard-hitting dispersion that effectively covers large venue spaces.

Engineered for precise low-end fidelity, it features a focused frequency response of 38 Hz to 200 Hz alongside a resonant frequency (Fs) of 38 Hz. This exceptionally tight sonic character ensures punchy, transparent bass reproduction and highly efficient crossover integration for pure acoustic delivery.

Built to withstand heavy touring demands, the unit features an overall diameter of 460 mm and a mounting depth of 241 mm. Weighing in at 16.7 Kg with a standard 8 ohms nominal impedance, it is a highly reliable component ready for integration into rugged plywood cabinets and professional rigging hardware.
