15 LFA 700

Name: 15 LFA 700
Brand: POWERX PRO
Availability: InStock

The 15 LFA 700 is a highly versatile 15-inch transducer engineered for the esteemed PRO SERIES. Representing a premier acoustic building block, this driver is exceptionally suited for 2-way passive full-range builds, stage monitoring, and compact touring setups.

Showcasing robust acoustic output, it handles a continuous 700 AES Watts while accommodating dynamic program peaks up to 1400 Watts. A highly efficient 99 dB (1W/1M) sensitivity ensures the speaker translates power into substantial overall loudness, maintaining crystal-clear dynamic headroom under demanding live conditions.

Its internal acoustics are powered by a substantial 99.5 mm (4-inch) voice coil paired with a dependable Ferrite magnet structure. This advanced driver configuration provides strict mechanical control over the cone, resulting in consistent, phase-accurate sound dispersion across the listening field.

Offering a highly musical frequency response of 45 Hz to 1.5 KHz and a resonant frequency (Fs) of 45 Hz, it delivers exceptional fidelity. The sonic character yields punchy, tight bass alongside transparent lower mids, allowing for seamless crossover efficiency and uncompromising acoustic purity.

Built into a durable frame measuring 393 mm in diameter and 176 mm deep, it is crafted for rigorous venue use. At a manageable weight of 13.5 Kg with an 8 ohms nominal impedance, this transducer is highly road-worthy and ready to be loaded into heavily rigged professional enclosures.
