The only bad part about this is that a screwdriver is needed to adjust them. It would have been nice if Yamaha had designed a better base that could be firm yet still be adjusted without the use of tools. The main contents of the box. All decoding and amplification are handled by the decoder unit. The rear speakers have quite a bit more wire so they can be placed well away from the fronts.
All satellites are identical other than the differing lengths of speaker wire.
The subwoofer is not all that impressive to look at, but it does feature some interesting technology to give it tighter bass. The YST system adjusts the negative impedance generation as the speaker moves, creating a hard, rigid cone that prevents deep resonant waves from leaking out. This means that the full bass wave power is forced out through the air port, resulting in clear, powerful bass. The bass unit still is not as fancy as what you get with Klipsch or Videologic products, but then again it costs significantly less than either of the competing products from those manufacturers. The controls on the decoder are very simple and easy to adjust.
