Sale price Price $2,000.00 Regular price


This product includes all wood materials to construct one PAIR of front horns. The pieces are shipped as a Flat Pack (disassembled).  The customer must finish assemble the horn.  All prices are in Canadian Funds.

The Dual Planar Front Horn covers from 250Hz to 15kHz using a dual planar transducers (BG Neo8) or equivalent LM8K from Radian Audio.  This product ships as a flat pack consisting of seventeen layers of 18mm thick baltic birch plywood.  


The E-250 is ideally suited for 2-channel high quality music playback systems where the highest sound quality is required.  This horn provides true time coherent point source sound.  Horn loading the planar drivers expands upon an already world class transducer by increasing it's sensitivity and bandwidth with the front horn.  Unrivaled by any direct radiating counterpart, the E-250 will produce a near flat power response creating very accurate timbre for instruments and vocals.  This front horn is not suitable for live sound reinforcement due to the overall power handling limitations.
