The subwoofer is a 11.25" x 6.5" x 9.75" enclosure that is the center of the system. The five speakers connect to the rear of the device and the outputs that lead to the computer come from here. Also coming from here is the X-540's wired remote. This small unit controls the power, volume, bass, and can toggle Matrix mode.
This box is a container for the 5.25" ported driver which delivers the X-540's bass. The driver is not particularly large, but with 25W of power and a good sized cabinet, it can deliver more bass than one would assume and it adds a lot to the system's range. The use of a downward firing bass should maximize the effect and uniform sound coverage while not requiring a lot of room.
To test the X-540s I hooked it up to my computer and the my Playstation 2 in order to get an idea of the full range of uses. During this time I watched a DVD and played a few games on both the computer and PS2. Gaming was really the focus as this is the best usage of a surround sound speaker system and the intended purpose of this kit.
The system was easy to set up and, given the price, I was impressed with the sound quality. With a total of 70W (RMS) and 140W peak no one will be expecting this system to blow the doors off of your house, but it is sufficiently powerful to deliver a very nice gaming experience. Overall the system does not have the clarity of some of the models I have tested from Klipsh nor does it have the power of the high-wattage systems but it brings along good channel differentiation and enough volume to get the job done.
Despite the speakers and subwoofer being relatively lightweight, the sound was clean and there was little to no distortion. The target buyer for this product should be really happy with its ability to create a uniform sound around the user and that despite the small wattage number, it is enough to improve ones gaming/movie experience considerably and really get you feeling what is going on.
