These speakers are replacing Creative GigaWorks S750 THX Certified, 7.1 750 watts that lasted 11 years in perfect condition. The Z906 is connected to a windows Creative X-Fi Elite Pro 7.1, THX Certified sound card.

2 months of use replacing an old home studio gas plant which began to snore Impeccable sound quality No breath Easy to adjust: you can adjust the volume of each voice (practice to adjust subwoofer) Effects remix 2 to 5, etc. ..

While this is one of the most expensive options on the market for 5.1 computer speakers, the power and audio quality of this system is hard to argue with. They are 500 watt RMS speakers with peak power of 1000 watts, which means you get a ton of volume out of them, and the subwoofer provides plenty...

Excellent Great Sound Easy to use, just what you would expect from Logitech

The quality of these speakers is amazing! I have set them up properly (three in the front and two in the back) and I really feel like I'm immersed in whatever I'm doing. Even at low volumes, the bass has a deep tone to it that makes the house shake.

This was really my first surround sound system, and I can say I am pleased. This system is compact, one compact center channel speaker, a left and right compact speaker, a compact left and right rear speaker, and a nice sized subwoofer.

Excellent sound quality playing music and movies and games. When the thunder rumbles in a game I can feel it vibrate my chest. It really amps up the experience. The remote is a nice feature but because I use these for my desktop pc I haven't really used it much. Would buy again.

I own the z-680, z-5500, and now the z-906 I could not be happier with these speakers. They sound fantastic. Some people say they are expensive but I dare you to walk into Best Buy and find a better 5.1 system for $399.99. Trust me you wont cause I used to work there.

Excellent sound overall; The bass will not disappoint; Sound is super clear and loud without distortion

Logitech replaced the control module from one with a LCD display to just lights; Still gets the job done just in my opinion not as nice

I've had many systems over the years from floorstanders, to bookshelf speakers and the last being a bose soundbar which i sold. I recently brought a sonos playbar from very which was faulty out the box so sent it back but i have been eying up the logitech for a while but for some reason bypassed it...

only one thing to say about this & that`s top quality great sound & easy to install i`m very happy with it.
