The Most Powerful Passive home Loudspeaker Ever Made!
To eclipse the sound found in a live hall one must atone for sound nodes and acoustic limitations of the hall. This is attempted by providing a nearly perfect point-source of sound directed through Gottenburg's logarithmic horn.
To reproduce distortion-free bass down to below 15hz one must have a diaphragm large enough to achieve 15 hz without the use of pumping excessive amounts of air. Gottenburg's 32" wide-Band woofer needs less than 2 . 5 mm of movement (x-max) to reproduce bass near 90db (1 watt 1 meter) at 15 hz!
Matched with reference tube and transistor amplification Gottenburg pushes beyond other Statement loudspeakers in usable bandwidth, efficiency, detail, imaging, tone, and sonic textures.
From Review Page on Gottenburg-Odin
Fred Crane, Musician, Audio Dealer, Audiophile, Boston August, 2016
Enter the Gottenburg Odin. It manages all of the things a mammoth statement speaker should, but that's not what makes it truly great. So often a large speaker, horn or otherwise, is thought to be a proclaimer of maximum volume, realistic dynamics, and thunderous bass. Some even manage those. Well the Gottenburg handles those elements with ease, but it goes further. What it does better than any speaker in my experience are harmonic textures that exist in a live hall; those subtle undertones and overtones that make all notes richer, not just those low on the chart. Think of it as the difference between playing a C chord on a spinet versus a C chord on a 9 ft Hamburg Steinway. It's the richness of real music.
You'll never know just how powerful a cello is until you hear it on the Gottenburg's. (Richter on these is a physical experience.) It also manages to be seamless in the way that a single driver speaker is seamless ... incredible.
One can enjoy them near or far-field (impossible with most horn designs), and when thunder and God's own fury needs to erupt from the Gottenburg, you will cower and rejoice.
Hundreds of design options: from old-world traditional to contemporary. Sea Dragons at the top or none... Finished in 30 coats of hand-rubbed colour with silver horns or in heirloom woods with natural bronze horns you build Gottenburg to fit Your Palace!

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 frequency to mid-band from the super woofer pass through the center of the horn without disturbing the smaller driver (an acoustic trick) making a true time-coherent point source of sound. Additionally, the back side of the huge bronze horn is utilized to further augment the super woofer improving bass, dispersion and reducing distortion.
The whole system works in unison as an organic, ultra-wide band point source of sound.
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 is perfect for "Statement" tube based systems. Recommended power 10-200 wpc
Try Gottenburg Demo with earbuds or headphones!
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.
