Quality, the time was cheaper.

The sound is pleasant, not perfect but for the music's room, PC, console and TV playback truly enjoyable parts.

The build quality is really solid, although the contacts for the audio wires are not perfect but they do their job.

Manual control I think is not so great, the boxes I usually only at 180 ° -220 ° position, however, you realize the quieter one turns that the audio direction is irregular, that is left losing some transmission.

Meanwhile, I have on the left box a still existing soft crackling / crackle when voltage is present - you will not stop when the pit play something but you notice it when it's quiet times.

When I look at the current price, you would have to give P / L technically 3 stars because the things, however, have cost 70 times, I keep at the 4 stars.
