Sound Central

What makes our audio great

The goal of speaker design is to let you hear the music, sound effects, and speech as it sounded when it was performed or mixed in the studio. The best speakers use carefully tuned drivers that replicate the high frequency (or treble), the mid-range sounds, and the low bass tones.

Without the right drivers, you're only hearing part of what was intended.

Built-in PC speakers are fine for general use, but lack the range many people demand for music, movies, and games. Our answer to that is a line of multimedia speakers that are a combination of quality, design, sound testing, and value.

We don’t simply buy parts off the shelf. We laser tune different types of drivers. We modify the shapes, experiment with materials, and use digital components to improve sound quality. Our goal is to deliver fidelity as close to the original sound as possible.

In the chart below, acoustical measurements were taken to characterize the Logitech Z-Cinema against a top-tier competing speaker. This measurement compares the two systems’ performance with regards to critical acoustical design.

Frequency Response: Logitech Z Cinéma vs. Competing Product

Blue line: Flat Sound Pressure Level (SPL) line – This line is the target frequency response. Flat means that the speaker is exactly reproducing the levels of the original recording.

Red line: Logitech Z-Cinéma – This line is very close to perfect because of its superior 3 way design, and high fidelity silk dome tweeters.

Grey line: A top tier competitor – This speaker has a lower fidelity sound, shown by the very poor performance in the bass frequencies (on the left of the graph) and in the treble frequencies (on the right of the graph). This results in sound that is out of balance and less natural.

We overcome the limitations of conventional audio products in a variety of ways:

Balance big sound with small size
Our portable Pure-Fi™ speakers for iPod® are compact, easy to carry, and work well for all kinds of music in a variety of spaces, indoor and out. Some iPod speakers employ a Digital Signal Processor (DSP) to enhance the bass. This enables smaller speakers to deliver excellent sound. Others use advanced acoustics to deliver exceptionally clear sound with maximum bass.

Control the frequency
Two drivers are often used to boost sound in small speakers. Overlapping frequencies can cancel each other out and create zones with too much or too little sound (also known as “spatial interference”).

To enhance our directional speakers, we developed a technology called Frequency Directed Dual Drivers (FDD²). We use two identical full-range drivers in each speaker. A special filter that detects specific frequencies is applied to one of the drivers. It gradually mutes that driver as needed to prevent spatial interference. The result is superior sound quality throughout the entire frequency range of the speaker.

Great sound throughout the room (also known as “omnidirectional acoustics”)
Conventional speakers focus sound in one direction, creating a single spot for optimal listening. Yet some listeners don’t want to be tied down to their desk, their couch, or their home.

With this is mind, we’ve adapted techniques used in high-end home theatre designs to develop omnidirectional acoustics for digital music and PC speakers. Within each speaker, one full-range driver faces forward, the other backward. This way, two speakers can then transmit sound evenly in all directions. Just as in a concert hall, a wider range of frequencies reflects off the walls to provide great sound across a larger listening area.
