Crackling fireworks soared past our ears with impressive realism as they moved across the screen. High-pitched details were sometimes lost or a little subdued, but this was made up for by the immersive and convincing surround sound effect.

The midrange was crisp and clear, so we were able to hear fine details and effects in background noises as well as intonations in conversations that were obscured by other speakers. Adjusting the bass using the dial on the subwoofer produced a more sedate but still deep and rumbling thump that still did justice to explosions and dramatic, orchestral soundtracks. The bass was thunderously overwhelming at first in most movies. The headphone socket and volume controls are conveniently located on the right satellite, but the bass control is on the back of the subwoofer and can be awkward to reach. Unusually, the front right satellite acts as the hub for the 3.5mm stereo input cables instead of the subwoofer.Д«oth these audio input cables and the cables connecting the satellites to the subwoofer, as well as the corresponding ports on the subwoofer itself, are individually colour coded so set up is a snap. Therefore as with the headphone socket there needs to be a direct connection between pin 15 and 11 to make the speaker work.The X-530's subwoofer and satellites look almost identical to those included with its 2.1 counterpart, the X-230, which we'll be looking at very soon. The other side of the DPDT links pin 15 and 11 together which must form another circuit inside the Subwoofer activating the amplifier and speakers. But when it is on it goes to the Power LED and then on to more things that I haven't looked at. When the switch is closed the 6V isn't taken anywhere significant or obvious as far as I could tell. There is 6V coming into the speaker and this passes through the main DPDT Switch.

Im guessing pin 11 is some sort of Ground or leads onto another circuit inside the Subwoofer, therefore can't really so much with pin 11. LED CircuitД¦V comes out of the switch and into the power LED, this then has a few resistors but ends up at pin 11. If there is not a direct connection between 8 and 12 sound will only come out of the headphone socket. This determines whether or not to allow the speakers and amplifier to work in the Subwoofer. The headphone socket contains two pins that break the circuit if anything is plugged in. The Potentiometer has 6 Input and Outputs for each channel, providing between 10K and 0K resistance. *I think this is correct however I may be wrong, The numbers are different from common 15pin HD D-connectors but they follow the pinout diagram. The Front Right Speaker also controls the output, by means of the potentiometer, switch and headphone sockets, the functions of the circuit are at the bottom and the pinout for the 15pin HD D-connector is below. These are the sound inputs and they pass through a small circuit in the Front Right speaker when they then go to the Subwoofer to be amplified and distributed. There are 3 inputs to this speaker to make the whole system work: The Front right speaker controls the inputs and outputs of the system.
