La XXL Inside, Italian company based in the province of Florence, has created K-Array, the thinnest array system being sold at the moment. The units look more like plasma screens than audio array modules. However, they boast a great performance.
The system offers two models, KH4 and KS4, respectively the “full range” and subwoofer of the system. In spite of their incredible dimensions (112x60x16 cm) they produce continuous 139dB and 137dB @ 1m.
These units are also very light: about 40kg (KH4) and 30Kg (KS4).
