Bose has a few different AC-powered computer speaker systems in its Companion line. All of the systems are lightweight and small enough to sit on your computer desk.
One of the systems delivers convincing 5.1 surround sound, even though it is only a 2.1 speaker system, thanks to its digital audio-signal processing technology. It is a three-piece computer sound system that weighs 27 pounds in total. This weight is spread out over two satellite speakers and a subwoofer – the subwoofer sits out of sight under your desk, and the satellite PC speakers take up very little space on your desk because they balance on slender legs.
The Bose Companion speakers have simple designs and large front-facing driver ports. One of the 2.0 models houses the system's single control, a volume dial, on the right-hand speaker, along with a headphone jack. At the back, there are two 3.5mm analog inputs: one marked for a PC connection and the other that's designated as an auxiliary port for connecting a portable media player or smartphone. Other Bose Companion speakers have separate control pods, instead of housing volume, headphone and auxiliary ports on the satellite speakers themselves.
Some Bose Companion systems include wide soundstages, thanks to the company’s proprietary stereo digital processing circuitry. Still, others only have an analog input, and it's unlikely that the analog-to-digital signal conversion sounds as good as a purely digital signal. The user manual contains instructions on how to set your computer volume to get the best sound quality from your speakers.
Bose also offers computer speakers that have premium features like active electronic equalization and compression circuitry. Both of these keep sound from distorting at high volumes and across the entire frequency response range. Bose also magnetically shields the satellite speakers to keep them from interfering with computer monitors and magnetic storage media.
The Bose systems don’t come with remote controls. The speakers do come with power adaptors, so you can still use them if you live outside of the United States.
The computer speaker systems in the Bose Companion series are high end and made by a well-known brand in the audio equipment industry. With 5.1 surround sound at the top end of its offerings, you can use the speakers to play games, watch movies and listen to music.
