Line Source Element

The 2-way line source unit QL 906 is equipped with two 1“ drivers coupled to a waveformer and two 8“ neodymium speakers combined with outstanding AQF acoustic filters. This filters, compounds of reticulated aminoplastic foams, dampen standing waves inside the speaker system and cancel parasetical side-lobars within the working direction, creating a wide while smooth horizontal dispersion and a perfect vertical scalability.
