Mix of low prices for high quality and good power;
With 130WRMS small box of this system is a very good point, first of all by the fact that it is compact, and at the request of the roar, the lion is present!
I'm not hiding anything and you admit that resents forced use, ie to push the volume up and ask him full bass, except for non-professional magic system, you can not fault this THX not resonate well as it does at low volume because it is not designed to, and even you will damage this system as it heats up quickly and the smell of heat is quickly feel when pushed to its limits (the box does not explode no, but the sound quality degrades rapidly when misused). It is the same for the treble 2x35WRMS sizzling when they abuse the volume again, and again, not a pleasant smell probably for the speakers spread. This problem is very common on any 2.1 system to know that the jack of most computers is too powerful for a system of this type and the problem is not the same when I plug him the plate, he 'll have 10 minutes to thoroughly volume really starts to heat it in the corner. A PC connected to the 2.5 / 3 volume and bass knob set fully it takes just 2 minutes to reach its limits in the treble level as low. For those reading this article I really say that I speak of "entrenchment", just do not exceed the limit for that purr for hours without flinching. For plenty loud sound just slightly more than half the volume and adjust the bass a little less than half, and you have a Z623 purring all his true style and without quality loss. It is useless to push too hard because the system by limiting a bit and having understood that he would never send him to no quality loss as the professional systems, we will see that this little two rounds in his pocket show you; namely that the subwoofer certainly sounds heavier and more powerful without abusing it, so by limiting the volume we do not speak of losses but gains! The quality is impeccable, the satellites transmit very good mids and good treble a little deeper, and the box down very low in frequency while maintaining a good offense and that is that this system is really nice because a lot other systems of this type clings to hold a low while that resonates the most roundly possible, finding out the air quietly and letting the pleasantly in the room.
So I would choose 9/10 my two THX that for almost two years are shaking every day when I can the walls of my room!
