The 1531 Horn Loudspeaker is based on a three way concept including a custom designed LF horn section design developed in 1992 by Lange Loudspeakers. Critical mid frequencies are reproduced by a horn coupled to an 8” driver and proprietary concentric phase plug. High frequencies are reproduced by a 76 mm coil/dome high frequency driver developed and made by Lange Loudspeakers in Switzerland. The 1531 has been designed primarily in order to offer better performance down to 90 Hz. If compared to our older and discontinued 9910 MHF Horn the 1531 includes a specific low frequency horn, derived from our H718 design, intended to cover frequencies from 90 Hz up. The folded horn does not include compression chambers nor flare irregularities or parallel walls that inevitably generate resonances. The system offers noticeable advantages in terms of controlled coverage, low harmonic distortion and impressive dynamic range

Intended primarily for dance halls and mid-sized installations the 1531 delivers outstanding sound quality. The 1531 is best used together with our H718, H721 or B218 subwoofers. Close attention has been dedicated to the geometry and position of the horns. Radiating areas have been placed as close as possible in order to interact in a constructive way. Cabinet size has been reduced as much as possible. The frontal area of the loudspeaker can be considered completely radiating and occupied by three horn mouths.
