Acoustic Innovations:


Viking Acoustics Hybrid Horn Loading Technology:

Non-compression hybrid loading. Horn is used for high-frequency driver in non-compression format and set with an air-gap and doubles as the bass-port or bass-horn for the woofer. On Berlin the back side of the horn overlaps 30% of the woofer to further increase bass and bass efficiency as well as limit on and off axis distortion. Gottenburg uses the front and back of the logarithmic horn.
