Portable And Desktop Computer Speakers For Mac

High Powered USB 3.0 Computer Speakers Get Louder

USB 3.0 Audio Devices
With all new Macintosh desktops and MacBook laptops shipping with SuperSpeed USB 3.0 ports, many Apple users are wondering what Mac accessories can take advantage of them. USB 3.0 drives and storage devices benefit most from the higher data transfer rates, but there's other improvements and benefits to the updated USB3 device specification. Most notably, it delivers higher current available for powering and recharging devices -- or can allow louder USB bus-powered computer speakers. Here, Gigabyte offers the first true USB3 powered computer speakers for desktop use.

USB 3.0 Speaker System

900 Miliamps Of Power


One of the notable changes to the USB 3.0 specification is that USB bus devices can now draw up to 900 milliamps of power off a USB3 port. Previously, USB 1.1 and USB 2.0 ports had a maximum of 500 milliamps available which limited bus-powered speakers to about 2.5 watts of maximum audio output. Higher speaker output wattage is possible *IF* the speaker is designed for USB3 which can theoretically deliver up to 4.5 watts instead.

Gigabyte's GP-S3000 USB3 Digital Speakers feature a new generation of USB 3.0 audio DAC (Digital-Analog-Converter) chipset that registers on the USB bus as a high-current, SuperSpeed USB 3.0 device. Using the electronics formula for wattage: Volts x Amps = Watts. And in the case of modern computers, 5 Volts of port power times USB3's 900 Milliamps = 4.5 Watts of potential output -- nearly doubling that of USB 1.1 / USB 2.0 speakers.

Gigabyte offers the S3000 speakers in either Black or White to suit your tastes. There's touch-sensitive Volume +/- Mute buttons atop one of the stereo speakers, an optional 1/8" stereo input jack, and large very high-quality speaker drivers with tuned-port for much better low-end bass response than the previous generation of USB computer speakers have ever been able to deliver. Expect more all-digital USB 3.0 high-power speaker systems to become available in the future.
