The most sought after loudspeaker in Europe is almost unknown in America.
Until now.
You've probably never heard of Sinus, because until recently, our loudspeakers have been completely unavailable in this country. But on the Continent, the Sinus name has long been synonymous with extraordinary sound reproduction. A sound so pure and true that Sinus of Sweden is now the largest manufacturer of fine loudspeaker systems in Western Europe.
Toward a near-perfect sound.
Traditionally, one of the major deterrents to pure sound reproduction has been the "masking effect" Masking effect is experienced as a blending or blurring of sound frequencies and is perceived by the human ear as distortion.
At the most advanced sound laboratories in Europe, Sinus engineers can reduce significantly these masking effects for an unexcelled clarity of sound.
Because of all the world's leading speaker manufacturers, we are one of the few to use both free field and reverberant chamber test methods for determining an accurate and truly representative measure of sound quality.
A second important characteristic of fine sound reproduction is in the loudspeaker's capacity to reproduce transient signals quickly and accurately. Transients are rapid sequences of fundamental tones and varying overtones which identify a particular sound or instrument.
Input signal.
This loudspeaker exaggerates the initial and final sections of the signal. The result is a sharp, distorted sound.
In this case the speaker is unable to reproduce the signal correctly or quickly enough.
Here the resultant sound is lifeless and unclear.
Here the speaker (Sinus 3400) has been able to reproduce the signal with sufficient speed and accuracy; qualities we require in every Sinus loudspeaker.
The virtual elimination of masking effects, coupled with exceptionally fast and accurate reproduction of transients are the two most important objectives at Sinus laboratories in moving toward the near-perfect sound.
Toward a near-perfect loudspeaker.
All loudspeakers in the Sinus line have been perfected to exhibit minimal distortion due to masking effects and to reproduce transients with maximum speed and accuracy.
Sinus offers two basic types of speaker design in five models. Our acoustic suspension loudspeakers, the Sinus 2300 and 3400 Series, boast an unusually open and natural sound. Our bass reflex loudspeakers introduce a number of innovative design and engineering departures. The 44F Series features horizontal placement of midrange and tweeter units to create a more even reproduction of both direct and reflected sound. The 3000XB Series offers a two-way bass reflex, time-aligned speaker with a specially-constructed 8" woofer.
At the top of the Sinus line, our 55M Series loudspeaker features a truly unique twin-woofer system.
The bass reproduction is so astounding that the 55M is frequently compared to systems incorporating sub woofers and costing four times as much.
All Sinus loudspeakers are compact in size, made with natural wood veneers throughout and sold only in matched pairs.
In the unique 55M Series Twin-Woofer System, the double bass is
electronically and acoustically coupled in a cast aluminum
accelerator tunnel. The unit will reproduce sound so low that
it can be felt, but not heard.
