980-000402-cr Z623 400 Watt Home Speaker System, 2.1 Speaker System (Renewed), One Size, Black

Deep, Room-Filling Sound That Punches Above Its Price I’ve owned plenty of computer speakers over the years, but the Logitech Z623 system really stands out. Even though mine came as an Amazon Renewed set, it looked and felt practically new. Setup was quick—just plug in the satellites and subwoofer, connect an input, and you’re ready to go. The sound is where this system shines. At moderate volume, the audio is clear and well balanced, but when you turn it up, the subwoofer delivers bass that can rattle windows and shake picture frames. Movies, music, and games all feel immersive with this much low-end punch. I like having the bass knob right on the speaker—it makes it easy to dial in just the right level without fiddling with software. Inputs are flexible too: you can run multiple devices through the RCA and 3.5mm jacks. I’ve had my computer, TV, and even a portable music player hooked up at the same time. The satellites are compact but produce crisp highs and mids, and the subwoofer anchors everything with authority. One thing to keep in mind: this is a wired system, and it takes up some floor space with the big sub. Also, the bass can overpower if you crank it too high, so fine-tuning is important depending on the room. Bottom line: If you want a powerful, THX-certified 2.1 system that fills a room with rich sound, the Z623 is a fantastic value—even in renewed condition. It’s built to last and delivers audio that rivals systems costing much more.

I've had these for about 6 years now and these are the best speakers I've had for my PC. The subwoofer is the star of the show though. It's so punchy and you barely need to turn the nob to half! If you can tune with an EQ, it's even better.

Unless you're looking for an audiophile type system or something that will rattle the doors, this system sounds great. It seems well made and sturdy, and the balance of subwoofer frequency versus the mids and highs is good. The bass never sounds like it's struggling, muddy, or bottoming out. I've had a Klipsch setup before that sounded great, too, but it cost much more than this one. And I tried a cheap $35 Edifier setup that was terrible in sound quality, build quality, and it developed an annoying electric ticking noise the first week I had it. Too bad, because I have other, higher quality Edifier speakers that work great for my turntable. You get what you pay for. This speaker system is the best sound I've found for such a reasonable price. I'm totally happy with how it sounds, looks, and feels, and I'm picky about my speakers.

The speakers sound great, with the potential to deliver powerful bass if you're into that. I have yet to experience any significant issues with the functionality of the speakers. The speakers feel substantial and sturdy in the hands. The wires feel high quality. Physical damage appears to be unlikely to damage the functionality of the speakers. The volume knobs feel good to use and the power button is satisfyingly tactile. The one complaint about functionality I have, is that when using the knob to turn the volume very low (lower than most people would realistically ever need to turn it) the volume of the right speaker reaches zero slightly prior to the left speaker, leaving the left speaker much louder than the right at very low volumes. It appears that the external frame of the subwoofer is made of a hard cardboard-like material. Though generally strong enough, the material has the potential to be smushed on the corners, as was the case with mine on arrival, (though I purchased them renewed, so this was not a terrible surprise). This damage appears similar to the way an old hardcover textbook gets bent corners. I cannot say for sure how strong it might be if something hits it on the side, but it feels sturdy and hard. I purchased them renewed, sold by "Action Gear," who packaged it poorly. Though it was packaged with plenty of bubble wrap (arguably too much), the box was far too large and the contents shook around inside. Nothing bad happened, although it did create potential for damage, as the heavy subwoofer was packaged with bubblewrap on only four of the six sides.

I do like high end music production and expensive equipment for sound. This speaker system is NOT in that catigory. You can't get that for that kind of quality for this kind of money and this kind of setup. Having said that, WOW (!!!), these are the best speakers I have ever owned for under $100! (refurbished) There is enough clarity across the sound spectrum that you can pick out parts with ease. They will provide great entertainment for games and music... I am a musician: I like to hear parts, and with these speakers, you can hear parts easily. If you like bass... get these. There IS bass, and lots of it! For general listening I turn down the bass a bit so that it doesn't dominate the room. Of course, that also depends on how you set up the system: Put your woofer on the floor and you may not get all that bass... What a buy! Fantastic. Oh, that high pitched sound others complain about? The high end of these speakers is a bit rough sounding to a trained ear, but to you average Joe, these sound wonderful on the high end, although a bit bright.

These are the best desktop speakers I've ever owned at this price point (retail new $150 to $200 range). Clear highs and mids. The bass greats crazy loud if you're into that sort of thing. I prefer more audiophile grade monitors for music, but these speakers are great for games and movies with lots of things going on. Definitely the best non audiophile speakers for the money. I read some people had a lot of bad luck ordering refurbished, but my experience was just fine. Shipping was quick, the speakers were in very good shape with no scuffs or wear and tear. They were easy to hook up with zero distortion or static. I could be an exception, I don't know, I can only speak for myself and my experience both in purchase and in use has been excellent.

My box came with virtually no damage, unlike others have reported. So, I was thinking I was lucky and was going to get a really nice set of these Z623 speakers. Upon UN-plasticing the speakers I became even more hopeful because they looked immaculate, just like new. The problem was with the subwoofer. It makes no sound at all. I've tried various points on the bass knob, various volumes, I've disconnected and reconnected the speakers and their inputs in every order I could think. I've tried both 3.5mm inputs, as well as the RCA inputs. I've tried my PC (which was where the speakers were intended to be placed), I've tried a tablet, even tried a frequency generator. But the bass input seems to only go to the stereo speakers, the sub never makes a sound. 60Hz or lower is something you'd expect to make the subwoofer at least try and emulate the sound. It's super disappointing, I've owned Logitech stuff for many years. It's generally good stuff, I'm even typing this on a G910 keyboard. But it looks like "Refurbished" doesn't actually mean "fully functional" like it's supposed to.

I must have lucked out compared to what other people are sharing. My box came a little beat up and there was an old sticker indicating that must have been in storage or something since 2019. The speakers and sub themselves were virtually untouched and still in their wrapping. Minimal wear on the traction pads underneath the satellite speakers. I listened to the Logitech Z623 (this item) compared to the Klipsch ProMedia 2.1 and Edifier M3200, all within the same price range. The Logitech certainly sounded the best and the bass was much cleaner given the larger subwoofer driver size (7.0" vs. 6.5" vs. 5.5" respectively). Only complaint would be the look and size/shape of the satellite speakers, but that's worth dealing with in comparison to how well they sound. Definitely recommend!

Para ser reacondicionado me sorprendió el buen estado en el que están. La caja no tenía mucha protección que digamos como debería, pero aún así llegaron impecables y funcionando como debe. Por el precio me pareció una ganga. Lástima que en el video no se escuche como en vivo realmente suenan. Es un equipo bastante decente para ser 2.1, no soy un audiófilo de "hueso colorado", pero si me gusta un buen sonido, y el de este equipo se nota, a mi parecer esta equilibrado tanto medios como agudos para no tener tweeter dedicado, y el subwoofer ya se ajusta al gusto de cada quien gracias a su perilla dedicada de bajos.

Firstly, the product arrived on time and in excellent condition. Cudos to the supplier. Also, system was advertised as refurbished......It arrived as new and much better than anticipated. Most of my listening is done on desk top therefore it was paramount for me to have GOOD sound. The Logitech 400 w system impressed beyond expectations and I am thrilled to have gone this route. Highly reccomended to anyone who is finnicky about their sound and music quality!

En mi caso si me llegó en su empaque original, algo maltratada la caja pero era de esperarse en un producto “Reacondicionado”. Al abrir la caja noté que estaban algo sucias, pero solo limpié un poco y listo, el subwoofer venía en buen estado también. Las conecté con el cable auxiliar a mi Alexa, mi laptop la tengo vinculada a mi Alexa, así que puedo usarla por Bluetooth con mi Alexa y lo que reproduzca en mi laptop, se pasará a mi Alexa y de mi Alexa por las bocinas. Adjunto video de cómo se escuchan, se puede apreciar un poco como retumban mis ventanas y eso que no subí el volumen al máximo. En general, estoy muy satisfecho con mi compra, no encontré ningún defecto más que pequeños daños estéticos y con algo de suciedad, pero es lo de menos, mientras las bocinas suenen muy bien yo estoy feliz. 🤩

Took a chance on refurbished, as it seems it's hit and miss. I was lucky and got a good set. The sound is unbelievable. I had them at half volume for first test, and BOOM, blew me back in my chair, it surprised me. Very loud, very clear, deep and rich sound. That's what you want for computer audio whether it's games, movies or music. Very happy with these.

Superb system! Was a little iffy on getting something refurbished from Amazon but I’m glad I did! I saved money and got an awesome system. Only thing wrong with the system is a cosmetic chip on the subwoofer but other than that it’s awesome
