Customer Ratings & Reviews

the bass is great and it does get very loud. its hard to tell about clarity cause so many things go into it but it beats my last set and you can tell the difference in speakers with the wattage and these pump well with lil issues

I have a set that I purchased for work. This new set replaces my Klipsch set at home. These speakers are extremely clear and can get very loud in excess of 100db. Would highly recommend if your looking for something that’ll wake the dead.

I am an audio artist. My original Logitech surround speakers on my computer finally wore out after 11 years of daily use. I was trying to find something that could replace my old speakers. I got this because I trust the Logitech brand, as they have excellent sound. When I tried hooking these up to my computer the plugs did not match up and would not plug in properly to my computer. I was just going to take them back and exchange. I had an extra day before I could go exchange them. Playfully, I decided to try and hook them up to my tv. OMG... it worked, and not only that.. the sound was so incredible. I heard things in my movies that I never heard in prior tv's or speakers, stuff literally for me that until then, seemed omitted for the movies sound. The base goes A LOOOONG WAY !! I barely have it turned up and sometimes rumbles and I can feel the vibrations and the rest of the sound is crystal clear. You can't beat this for the money!!!

Got these for my dad for Christmas and my god the audio at full volume is still crystal clear as it is as only a third. The bass is powerful, you can feel the vibration in your bones. I'm probably gonna get myself a set of these..

Hands down the best speaker system for the price! I purchased my first set about 9 years ago and the woofer finally went out, so I bought a new set because I knew the quality of these speakers. From watching tv or movies, to listening to music these speakers outperform anything I have heard on the 2.1 level.

Great speakers. The sound is awesome, bangin bass and crisp highs. This is my second set, i have one on both of my computers. Highly recommend.

worked immediately when I plugged them into my windows 8 pc. GREAT sound. I like LOUD music and this gives great sound quality even when really loud. I have the bass at half and I sometimes have to turn the bass down because I am afraid of blowing my speakers because its so loud. haha. At that volume u have to practically yell to talk to someone who is 8 feet away.

really great for the price. Bass is nice and deep, easily controllable and doesn't sound muddy. Will recommend to all my friends. I use this for my PC while playing call of duty, and the sound is really good, can get very loud if you want it that way!

I'm currently listening with this system right now. I had used an older version at my work and was quite impressed, so I decided to pick up this newer release. Can't say I've really regretted it a bit. It may be more than some other cheap systems (Currently $130-140) but the sound quality, bass, and crispness are simply amazing. If you want to watch movies on your computer or truly enjoy music, I could not recommend anything but this but a budget-conscious listener. The bass is far stronger than you'll ever need it to be (I have popped a lightbulb), and the high, mid-tones, everything is simply excellent. 10/10 will never have a computer without a sound system again.

The sound quality of the Logitech Z623 2.1 Speaker System is amazing. It will blow you out of your room with the heavy bass and quality of the two desk speakers. My husband and I share the speakers between our computers with a channel switch and it's so nice to be able to listen to whatever we both choose. I use mine for work and he uses it for gaming and the quality is phenomenal.

400 watts is huge. Love the crisp clear sound and huge bass. Awesome for the price.

This is replacing an older Logitech speaker system. I wanted something with a bit more “punch”. This 400w system with larger drivers in the mids/tweeters and subwoofer does just that. Install was easy and I’m loving the audio quality. Bass is strong, tight but not boomy. Controls are handily located on front of right speaker. Aux and headphone jacks on side of right speaker are easily accessed. Great audio value for the price.

This speaker system is better than I imagined. The sound quality is very good and the two small speakers are quite compact - perfect for a computer desk. The power is excellent. A potential buyer should be very pleased. Would definitely buy again.

This small(er) speakers pack a punch. I was looking for something to replace an older set of Logitech speakers and found the Z623 system. I was drawn to these mainly because of the THX certification. This speakers can get loud, without getting distorted. Also like the multiple inputs and and base control on the speaker and not on the base itself.

The sound is great and the bass is exceptional. I do not use these speakers anywhere near their max volume and that may effect this conclusion. My computer's UPS is set up to switch off power to various devices when the computer goes to sleep or is shutdown. I am happy to report that when awakened or booted, these speakers come up with the power on. I mention this fact for those who might have a similar power setup. I also want to mention that there are no fixed wires, i.e., the three units plug together but can be completely unplugged. This was also important to me: I have several devices sitting on a large desk but all wiring between devices has wires going down through holes and coming up through another hole near the destination device. Clean looking desktop this way. Unfortunately. most computer speaker descriptions don't mention whether components are hardwired or with plugs.

I recently went to a relatives house and he has the z635 set from logitec and the sound wuality and bass absolutely blew me away. I had been looking for some new speakers for my system because my hearing is terrible but i didnt want to break the bank. So, i did some research and read up on the z623 system and decided to try them out. They were absolutely worth the purchase. Their sound quality is amazing and the bass is borderline over the top(in a good way). I’d absolutely recommend these speakers to anyone looking to upgrade their PC audio. 10/10

Deep tight bass. Only real improvement needed is longer wires. This is the problem with all wired computer speakers so I can't really complain.

For its size it punches a little. Feels a little immersive while gaming, family said it sounds like a distant thunderclap. I have a home office that I like to listen to music while I'm working. just takes that little extra thump from the bass to make me happy. Caught this on sale for around $100 and its worth every penny.

speakers produce a good sound, little adjustment to get sub sounding right, even better sound when run through a good dac sound card, for the price nice, hard to beat without going to a higher cost for a speaker set.

I admit that I had low expectations at this price point. However, these speakers have crystal clear sound, good bass, and they can get very loud. What more could you ask for? You will not be disappointed if you purchase these.
