I was looking to upgrade the standard speakers for my PC. I chose Logitech because i have owned one of thier older surround sound set up in the past and was pleased. This neer system blows that one away by far. Very simple and no nonsense controls. Clean finishes on the material. Instructions were simple. I live in a duplex. Theres no way i can turn the system up evwn close to its limits or i would get evicted. System can be heard from accross the street. Sounds aren't just simply Loud. Highs are very clearly highs and the subwoofer makes enough bass to rattle the floor and my puppys ears 10 out of 10

These speakers are really nice especially for the price. I had a cheap $20 set of logitech speakers that lasted me 7 years that finally gave out today. So I went and picked this up. Wow. These speakers are impressive! The bass is awesome and you can adjust it to your liking. The speakers can get veryyy loud and at first it may feel like the mids and highs are lackluster but they are very pure. You can hear so many different things going on and the sound is very crisp. Even on max volume there is no distortion just the sound being amplified. Definitely recommend.

I have personally tested many different sound systems within the past 2 decades, and this one is clearly the best one I have come across. Without going into the nitty gritty, it simply puts out an amazing sound, very satisfying bass, and perfectly balanced treble. The bass doesn't get distorted even when at max volume (unlike smaller models such as Z323) and it's more than enough to give your house a vibration. I have compared this piece side by side to the Z323 and Z513, and this clearly came out on top. Although it's an "old" design, you can tell why this system has the THX certificate. Definite recommendation!
