Bass-Horn Loudspeaker

VIENNA Bass-Horn by Viking Acoustics.


Vienna Bass-Horn. Over five years in development. The New Vienna will feature a large squared logarithmic horn made from sustainable hand Layered Italian poplar and finished in ten coats of glossy colour.


Vienna's form-factor is much like Berlin 1887 with our new Norse-Lock semi-active self-damping cabinet architecture but will have a larger Horn: 19" Round logarithmic or Rectangular form 18" x 22", Vienna will have a larger cabinet, and 12" dynamic paper pulp woofer with dual hybrid ceramic/AlNiCo motor. The new horn is loaded with our new 6" full-range driver which plays referentially from 100 hz to over 20 khz while the 12" bass-driver covers the very bottom of the sonic scale. Like Berlin R and BERLIN 1887 the mouth of the horn doubles as the bass port for the woofer while serving as wave-guide for the new full ranger. 


Vienna is designed to be a complete and final loudspeaker never lacking in aesthetic, never lacking in sonic scale, never lacking in the poetry of pure music.
