Fullrange chassis Monacor SPH-30X 4 Ohm

HiFi Fullrange in miniature SPH 30 X 4 Ohm

This full-range loudspeaker combines the smallest space a variety speaker technology highlights: an extremely light, but nevertheless well dampened Kevlar cone, a fully ventilated motor system, a high-quality neodymium magnet system with double magnet and a newly developed basket which particularly favorable assembly even with multiple arrangements allowed. Applications of this amazingly high efficiency small loudspeaker ranges from small speakers for background music or for example as rear speakers in home theater systems through use as Mittelhochtonlautsprecher or broadband midrange in high-end hi-fi speakers to multiple arrangements in column speakers.
