Logitech Z623 Speakers is rated 4.5 out of 5 by 37.
Rated 5 out of 5 by from *WoW* Excellent sound quality Good dimensional sound Decent build quality Two 3.5mm inputs The bass and treble are perfectly tuned out of the box, but if you want to add more bass there's a dedicated rotary dial on the right-hand speaker. They're well built too. The subwoofer is one of the smaller ones I've seen, but it did just as good a job of bass reproduction as ones the size of a small fridge. The satellites compliment it perfectly, being adequately weighted in terms of both construction and sound.

Rated 5 out of 5 by from Sounds awesome I bought these speakers for child's bedroom and was pleasantly surprised with the sound they supplied. For the price they sound way better than expected. Great value, great quality, easy setup.

Rated 5 out of 5 by from Easy to install. Excellent sound. Great price! This is the second Z623 system I've purchased. Logitech is a superior product over the Bose system I bough a few years ago. The Z623 turns ordinary TV movies into a cinematic experience.

Rated 3 out of 5 by from Torn...Good value, Loud, but not great Good ish speakers. Loud base and clear treble but frequency response is uneven. Sounds like listening to 2 seperate speakers. Not great for music. Turns your favourite song into a Michael Bay movie trailer. Deep rumbling base enough to annoy your neighbour's neighbour. Great if you love base, or have a good equaliser and want clear sound. By default they are loud. Cranking the base you can hear port noise almost like my uncle breathing(loudly). Trebbly is sharp but sub holds on until about 300hz. The low pass filter is set way too high on the sub. The base know adjust middle C on a paino. Speech in movies is crystal clear.

Rated 4 out of 5 by from Great value I bought this to replace a computer package sound system and it just didn't seem to have the power I wanted and now I have this unit and only use it low volume even though I have hearing problems. It is all that I could want in a decent sound system.

Rated 2 out of 5 by from Awesome speakers, but build quality not good I bought these speakers 18 months ago for my computer and the sound is magnificent but after 5 months the on/off switch was making some funny noises and eventually a humming noise started. I got it swapped over through the store but now 18 months later my second set is now doing the same thing. Lucky there's a 2 year warranty I guess.
