Hybrid 18H400 18" Loose Speaker 400W

Hybrid 18H400 18-Inch 400 W RMS 8-Ohm Speaker Driver

The Hybrid 18H400 is an 18-inch loose speaker driver intended for compatible loudspeaker construction, repair and replacement projects. It offers 400 W RMS power handling, an 8-ohm nominal impedance and a 4-inch voice coil. These specifications make it suitable for experienced enclosure builders, repair technicians and audio users looking for a large-format low-frequency driver, provided that the amplifier, enclosure and crossover or processing are correctly matched.

A pressed-metal basket supports the driver assembly, while the 120 oz ferrite magnet forms part of its motor structure. The driver has a stated sensitivity of 96 dB at 1 W/1 m, an efficiency rating of 2.4% and a resonant frequency of 34 Hz. These figures help qualified users assess its potential suitability for a planned enclosure. Final bass response, output and sound quality will depend on the cabinet design, tuning, amplification, filtering and installation; the driver should not be treated as a complete ready-to-use speaker system.
