Logitech’s Omnidirectional Advantage: Make Any Spot in Your Room a Sweet Spot
The Logitech Pure-Fi Express Plus omnidirectional speakers are designed to transmit sound more consistently over a wider range of space, so you never miss a beat--no matter where you are in the room.
|Traditional Versus Omnidirectional Loudspeakers|
Most speakers are designed to radiate sound in a fixed direction. As shown in Figure 1, traditional speakers optimize sound for a sweet spot located directly in front of the speakers. In other words, the sweet spot is limited to a constrained sound field that fans outward in one direction. If you’re outside the sweet spot, you’ll hear unbalanced sound due to loudspeaker directionality.
Logitech Audio Labs' omnidirectional speakers differ from traditional speakers. Designed to radiate sound more uniformly over a wider range of frequencies and angles, Logitech’s omnidirectional speakers create a broad sweet spot that is not dependent on a fixed listening position, as shown in Figure 2. The true hallmark of omnidirectional speakers, however, is the increased sound quality that comes from tonally balanced direct and reflected sound. The increased reverberant sound field also increases the sensation of spaciousness and listener envelopment. By designing loudspeakers to radiate sound more uniformly, Logitech delivers great sound to any spot in the room.

|Omnidirectional Acoustic Technology|
Normal stereo desktop speakers deliver sound from discrete sound locations, making a more focused sweet spot. Logitech’s omnidirectional speakers transmit sound consistently across the room and create a much larger sweet spot, allowing for great sound anywhere in the room.
