Acoustic Innovations:

 

Viking Acoustics Gottenburg Horn Loading Technology:

Non-compression loading. Ultra-fidelity wide-band driver set with by-pass to the 32" wide-band woofer with an air-gap. Low mid-band from the super woofer passes through the horn without disturbing the smaller driver. making a true time-coherent point source of sound. The back side of the huge bronze horn augment the super woofer furthering bass and dispersion. 

(patents pending)

Dual stage internal/external resonating system. Ultra-rigid cabinet is tuned with the use of tone-wood resonators to virtually eliminate standing waves within the cabinet. Lower resonator is visible through the dual by-pass ports located near the bottom of the loudspeaker.

 

Gottenburg: Featured in book of World's most extreme loudspeakers

Gottenburg  is perfect for "Statement" tube based systems. Recommended power 10-200 wpc

Gottenburg Prototype: testing with 8 watt Audio Tekne vacuum tube amplifier in a large room. Few passive loudspeakers in the World can fill a large room with perfectly strong yet natural sounding bass and the demo shows Gottenburg's excellent bass-slam even with a few watts. Ideally 22+ watts of high-volt tube power or 100+ watts solid state is desired.
