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.

(patents pending)

NorseLock© Semi-active Self-damping Cabinet Architecture: (SASDA) Machined heirloom wood front and rear baffles connected (locked) together with machined tone-wood pillars.

Jetted bass driver loading + frameless non-removable grills. larger woofer can be used with smaller opening reducing some low frequency distortion mechanically while augmenting low bass.

Now after a year of owning my L' Instrument 8PS speakers, I must say they are amazing speakers. I really can't explain how much I enjoy listening to them -- I am out of words to be honest to explain the detail these speakers have. Thanks for providing such a wonderful product. These speakers sound very good on complete tube set-up with a good TT with tube pre-amplifier to enhance the signal. Moreover they blast the bass-out when connected to solid-state and make them more dynamic for young generation... these speakers are simply superb on tube as well as solid state. I am so happy to own them and thanks very much for giving me such a masterpiece.

L'Instrument is a Perfect choice for the World's finest tube based systems. Recommended power 5-50 wpc

L'instrument's extra large horn is machined of fine tone-wood and turned by hand...and make a lifetime audio statement.
