Boston Acoustics has put effort into and managed to produce a great aesthetically pleasing system. Their design looks great and will easily catch any eye.
The system consists of 4 SST (Slimline Speaker Technology – thin, tall
and flat) satellites and an amplified 6 ½” subwoofer. The
package also includes 2x rear tower stands, an external transformer with
power cord, all necessary cables, a control pod, and an RCA-Phono adaptor.
The setup is fairly straightforward, and includes both labels and color-coding
on the back of the subwoofer and plugs. Some assembly is required
for the speaker pod/stands. The speakers can be either wall mounted, stand
mounted, or tower stand mounted (for the rear speakers). A manual is also
included with the system with instructions on assembly and setup for various
For 2.1 output: The system will require one analog output for 2.1 sound (the rear speakers
will not be used, but a virtualized Dolby Surround effect can be created).
For 4.1 Output: 2 stereo line outs for 4 speaker audio or 4-channel gaming or such as EAX and A3D.
For 5.1 (Virtualised center channel) Output: Digital
audio for Dolby Digital 5.1 is featured with the use of an RCA/Phono digital

speaker system will automatically detect the connection type and adjust
its output accordingly. The power LED flashes momentarily when switching
between modes, for example if you start playing a DVD movie or switch to
2 speaker mode by turning the surround volume all the way down. The only
indication I could see of what mode it was operating in was that the LED
was somewhat brighter when outputting 5.1 digital audio, as opposed to
2 or 4 channel stereo.
The control pod can be attached to any of the satellites, and is connected
to the subwoofer by a DIN connector. It features controls for the master
volume, surround volume, surround balance, and subwoofer volume. What it
lacks however, is a headphone or auxiliary input jack, something that a
system in this price range should have included. A remote control would
have been a welcome addition, but in the case of a desktop setup it is
more of a novelty than a necessity.
