Our Roots:

The fundamental design principles and science behind our loudspeakers goes back many decades. The quality of Pearl loudspeakers today is due in great part to the amazing pioneers of High Fidelity. The most prominent of which, we believe is Paul Voigt.  


Although, in reality, there is no comparison with the sound quality coming from a modern Pearl Acoustics design to Paul Voigt’s early efforts back in the 1930's, there are some rather strange coincidences. Both designs work on the principle of exponential quarter wave, exponential folded horns, wires are directly connected to the back of the drive cone, via simple terminal posts without crossovers or any other kind of electronic filtration in between.

In the very early days of Hi-Fi, before the days of solid state transistor amplifiers, one of the biggest challenges to be overcome was power, or rather the lack of it! The early tube or (valve) amplifiers struggled to produce even 8 watts of power. This meant that in order to reproduce realistic sound levels, loudspeakers needed to be extremely efficient. In the time of Paul Voigt, efficiency was only possible by building extremely large cabinets that completely dominated the listening room. They were able to produce an effortlessly deep and full sound, that some today still admire. But the sound was coloured by modern standards and the over complex, thin walled cabinets and poor quality glues often resulted in unwanted standing waves and buzzes.

Today Pearl Acoustics do not need to worry in the slightest about efficiency, power is readily available either from high quality tube or valve amplifiers or from solid state transistor amplifiers. However the same principles to realism in sound are born from having the wires from the microphone directly connected to an amplifier and two wires from an amplifier to the loudspeaker, with the utmost minimal amount of junk in-between.

Anyone listening to Pearl Acoustics loudspeakers will immediately notice the utmost realism of what they hear coupled with a natural, uncoloured tone that never induces fatigue in any way. Just like nature is not distorted, so it is with Pearl Acoustics speakers, they simply sound pure and sweet and are never tiring to listen to, even at relatively high volumes. 

In strictly scientific terms, Pearl Acoustics speakers might not be 'perfect' but we are convinced that they are as close to it as any speaker anywhere can ever be. 

Hence our company slogan close to perfection'.
