What's PC speaker here?

I was about three months looking for a home cinema center and had looked around intensely. Ultimately, I then decided to use this set, and for several reasons:
First, I am already operates functionally with my DVD recorder and my SAT-Receiver and did not feel like me now an amplifier / receiver / ask players on the shelf to be able to connect only to very sensible boxes.
Second, I did not come in this classic home cinema solution below 750 EUR - assuming equal quality - and more than two and half times is indeed compared to the z-5500th
Third were approximately 95% of the reviews very positive, also in terms of the quality of the technical components used.
However, I was pleasantly surprised by the quality. There really nothing to complain about.
With us is as I said the facility as home cinema center used, ie mainly movies and music. The music comes across crystal clear and the movies are absolute top, like in the movies.
The subwoofer is absolutely outrageous, fortunately you can front, rear and subwoofer separately control, so that the subwoofer does not become dominant. Only downside is that the subwoofer is not shielded and therefore can not be in the immediate vicinity of sources. This makes the wiring a bit more work, with us 5m optic cable were thus additionally due.
And now back to the topic "PC speakers" Our living room with about 30 m2 is certainly not small, but the sound limit is fully reached at approximately one third of the volume, according to two thirds of the neighbor should probably within two minutes standing at the front door and the first glasses wiggle already in the closet when the sub really is used.
My conclusion: For normal and even for demanding highly recommended. High-top, easy to set up and operate - what you really want more. However, this requires that you have the space for the sub (and that is with 35x35x40 cm not exactly small) - off the system / the TV.
In addition, the cables are no longer fixed to the boxes so that each extension is easily possible. So there is also the manufacturer to respond quickly to customer requests / criticism, thank Logitech!
