dc10audio's Horn Loudspeakers for Audiophiles

Viking Acoustics' Innovations

Before I started Viking Acoustics in 2007 I committed to have at least three acoustic innovations: otherwise, I was not interested in making another staid, status-quo, loudspeaker.

David Counsell, Founder Viking Acoustics

Some Viking Acoustics Innovations:

Unique (non-compression) Hybrid Horn Loading: Horn is both bass-reflex port and wave-guide for the tweeter or wide-band driver at the same time for unmatched coherence and live realistic sound-stage. The horns logarithmic shape increase bass efficiency and slam by as much as 5 db!

Internal resonator/damper: kills internal standing-waves and errant resonances within the cabinet while preserving acoustic energy

Floating semi active tone-wood baffle: provides damping while preserving acoustic energy

Resonator by-pass port: modulates the internal resonator

Semi Active Self Damping Cabinet: novel concept used only in Berlin 1887; entire cabinet is semi-active and self-damping

"Jet" Loaded Drivers: special driver loading where smaller opening is used for typically bass drivers to reduce off-axis distortion with minimal cross-over components

Our Philosophy:

Don't waste your watts on inefficient loudspeakers. Acoustic-suspension designs, rear ports, back-loaded bass-horns, sealed midrange drivers, overly large voice coils and complicated crossover networks all diminish efficiency, detail, imaging, coherence, and soundstage.

Semi Active Cabinet Architecture

Semi-active Self-damping Cabinet Architecture (SASDA)

The NorseLock Cabinet inspired by the articulated hulls of Viking Ships is a hybrid of the finest wood timbers and super rigid laminated panels.

Bass: we believe Bass is the most difficult to reproduce and get "Right." While getting mid-band and high-frequency right can be tricky too...bass is often the foundation of the music and requires the most acoustical know-how to implement. A double bass should sound right in weight and tone yet bass in the biggest symphonic music must be totally tectonic and without distortion: this is why we made the GOTTENBURG which is a culmination of all our innovations and built on the idea that pursuing the ultimate is not an extravagance!

Viking’s loudspeakers give you more reasons than ever to invest in a high-end vacuum tube system!

Viking Acoustics formerly dc10audio was founded by David Counsell in 2007. David built his first horn loudspeakers in Grass Valley, California in 1976 at age 14. Named the "dc10" a play-of-words on the infamous jet-liner and his initials. The original dc10 was a bass-horn loudspeaker with his unique "jet-loaded" tweeter mounted inside the mouth of the bass-horn. His first speaker sale was in 1977: by age 15 David was selling his horn speakers to Hi-Fi enthusiasts and people in the audio industry in and around Northern California.

The Viking Acoustics horn is a multi-function horn:

It is a bass-horn for the woofer and simultaneously for the mid-to-high-frequency driver as well. Bass, mid-range, and treble come out of the horn with the correct point-source timing!

Viking's unique horn ports all the drivers through the mouth of the horn even the dual woofers!
