Logitech Z-623

Logitech Z-623:

-The sound is deep and rich, and it have a 'three-dimensional' sound.

-Is not a bad system, but the Z2300 is a more good sistem. The design of the speakers are horrible, specially the subwoofer, but they're well built. 

-The subwoofer is not good, but it do a good job of bass. 

-The satellites compliment it perfectly, but are more bigs and and takes up much space on the table.

-If there's a slight niggle, it's that Logitech has elected to use the same connection system it uses on its lower-end speakers. The right satellite houses the power, volume and bass controls, and it connects to the sub-woofer via a proprietary VGA-style cable. The left speaker simply connects to the sub with a phono plug. 

-The system evidently works, and having power control on the desktop saves you having to lean over to a hidden sub to turn them on – and it's exactly the same system you'll find on Logitech's 15eur speakers.  

-They have THX certification.

-This speakers of Logitech are incorrectly builded, what happened Logitech?
