Z625 Powerful THX® Certified 2.1 Speaker System with Optical Input

Great build quality decent price and connection options with cables included. Other reviews are on the money. These are not meant to be played at low levels but are insane at higher levels.

I had a set of these for years and was very happy with them. The bass is rich and punchy and well balanced and the controls are great. After years of abuse I ruined the cable connections because I kept pushing against them with my foot while scooting a heavy recliner back, not realizing I was pushing directly against the cord connections. I'm honestly surprised they lasted that long considering what I was doing to them. My dogs would also use the subwoofer as a stand to look out the window. I'm not sure why but I replaced them with set of slightly cheaper speakers, the Klipsch ProMedia 2.1 THX set for $120, which many reviews assured me were great for the price and "punched above their weight." Neither was true. It's an understatement to say I was disappointed by them. The controls were awful and incapable of fine adjustment. The sound was muddy with no mids and the bass lacked that punch & definition that I loved in the Logitechs. After a couple months I got sick of them and decided to just eat the $120 and treat myself to another Logitech Z625 set. So worth it. I glued a 2x4 to the back of the subwoofer so that I won't damage them the way I did my last set. Great speakers. But my new favorite thing about them that I didn't even realize when I bought them is that they can play from the optical input and the 2.5mm stereo input simultaneously. This is huge for me because I have a personal desktop and a work desktop at the same desk and use a HDMI and peripheral switch to alternate between them. Previously I also needed an audio switch and I've already spent around $100 on switches having broken 3 of them because of their terrible plug designs. Not only will that not be a problem anymore, but I'll be able to hear my Zoom phone ring on my work PC even while using my personal PC. That's a big extra win for me and makes me like them even more than I did my last set.

I’m really impressed with the Logitech Z625. The sound is powerful and clear, and the 7-inch subwoofer delivers deep, strong bass that makes movies and games much more immersive. The THX certification definitely shows, especially during action scenes and music. Setup was easy, and I like having multiple input options. The speakers also feel well-built and solid. Overall, this is an excellent 2.1 speaker system if you want powerful sound, deep bass, and great grip on the audio experience without spending a fortune.

I've been listening to this system for a little over one month. For MANY years I had used the Boston BA745 2.1 speaker system with my computers. It was a system Gateway supplied with their computers (yes, that was long ago in a computer galaxy far, far away). They finally reached the end: the sub woofer would cut out, the left speaker volume would cut in half, wires had to be jiggled, subwoofer kicked, etc. I researched for months to find replacements. I asked for recommendations on Facebook. I read review after review on the internet. I narrowed it down to either the Klipsch ProMedia 2.1 THX system or the Logitech Z625 THX 2.1 system. I sent Klpisch a question via email...and I'm still waiting for an answer. After a week of waiting, I decided Klipsch didn't want my business, so I ordered the Logitech Z625 THX 2.1 system. I did not think any system would be notably better than the BA745 2.1 system. I couldn't have been more wrong! The first song I listened to on the Logitech Z625 THX 2.1 system was Paul Wilbur's "Worthy." Oh, wow! The bass this system puts out is stunning; I'm hearing low notes the previous speakers NEVER produced. I am hearing instruments on songs I had previously not heard. The improvement is beyond stunning. I have listened to a variety of musical styles and everything sounds amazing (keep in mind that speakers can only produce the quality of the original recording; a cheap recording and a lousy, imbalanced mix down in the studio cannot be overcome by any speaker system). The all around sound is outstanding. The bass has a deep, flowing, intensity instead of a cheap, thumping produced by low-quality, inefficient speakers. MId's and high's are very distinct; as mentioned, I'm hearing instruments - and vocal parts - not previously heard. Setup was extremely easy. Out of the box, the bass level was set slightly past 12:00 and I have not changed it (I thought I might have to turn it up, but it is excellent at the present setting). The volume can be turned up LOUD!! I haven't turned it up past 11:00, at that has been plenty (I usually have it about 9:00 or lower). I have no doubt this system would be very adequate for any sized room in a house. This system cost more than I had hoped to spend but compared to numerous other systems, this one is worth it. I highly recommend the Logitech Z625 THX 2.1 system to anyone shopping for computer speakers.

Here’s the thing. Everyone wants to claim they’re an audiophile and the best at reviewing every product they touch. I’m not going to do that. I’m just a random internet person who wants others to benefit from my experience so you can make a choice a bit easier. Let’s cut to the chase to avoid the giant wall of text.. If you’re coming off of cheap speakers, these are an excellent choice. If you already have a quality speaker set these probably aren’t worth a “side-grade”. Paired with the Bluetooth adapter from Logitech (others have noted that there are 3rd party cheaper ones) I’ve enjoyed this setup quite nicely. I haven’t experienced too many issues and setup was a breeze. Quirks with this system? DTS compatibility is low and was initially causing some electronic static noise to play when certain content was played. Turned that off in the OS if the device and have had no issues since. Higher frequencies are a little over-tuned, but that was mildly expected given the price point and only really hinders you if you have the ear for it and is adjustable through a system EQ pretty easily. Overall if you’re on the fence and aren’t looking to break the bank trying to hit some super high audiophile standard, it’s worth getting. Credentials? I’m just some tech nerd who’s worked in all types of industries. Don’t listen to me. 😂 But if it helps I was an A/V tech doing installs/live events for a national company for around 10 years. I do software/IT stuff now. Not sure why that matters but hey, if it helps, great. :)

Now I’m not a total audiophile but I do like my quality and clean sound, I’ve put these to the test specially with bass and it always came out crystal clear! It’s easy to hookup even for extreme beginners and always recommend the optical over audio. As far as how loud it gets, zero complaints and I like loud

These are the best computer speakers you could ever buy.

Hooked it up and was blown away at how good the sound is! Now lets talk about the bass.......HOLY! Worth every penny and then some. It was a huge upgrade and for the price point i really duno how u could go wrong. The sound could fill a large room with no issue at all.

Used the previous version, this definitely does not disappoint...

The sound quality is great. The bass is great. There is a bass dial so you can turn the bass completely off if you dont like bass. Playing video games every time something happens with bass its like thunder going through my room. I used 40$ speakers for years thinking it makes no difference to not have a woofer and i was very wrong. The sound is just amazing with these speakers and they are a purchase you will not regret. The max volume is very loud and if you max the volume and bass its like as loud as a night club and your entire house shake. The bass dial has a medium setting where the dial clicks so you know its at the middle and its simple to set it there and is still pretty bassy but its nice. The sound is very crisp and clean as well.

Thanks amazon for prompt delivery, I ordered on 11th and got on 14th evening(Mishandling by courier XD) Okay, let me tell you this is best speakers I have listen to from long time, once I installed JBL basstube with edifier speakers and powerful amplifier, and now these speakers give better sound (THX Rocks) Don't get distracted by bad reviews, they dont know a word about speakers. THX and bass PROS: Bass 11/10 Treble 9/10 Looks 10/10 Feel 10/10 Build Quality 10/10 (heavy and beautiful) Connectivity 10/10 (Easy to install) Can easily disturb your neighbours XD CONS: Right satellite speaker wire is thicccc af Main connecting wire is thin af, logitech tried to do cost cutting at wrong place! BASS will invite your neighbours XD, try some good bass songs at 12 midnight LOL //Final Verdict// If you are thinking to buy some good quality speakers for long time under 10k then this is must buy, you wont regret! I got this for 7,499 rupees, Go ahead and buy this baby to enjoy music, movies and games(THX boosts a lot!) //Tricks and Tips// If you are using 3.5mm jack connection then connect to right satellite speaker aux port, IDK but sound quality improved like 10-15% LOL Place your subwoofer on floor and in corner of room for damn smooth bass //EDIT// After 15 days of usage My parents are not allowing to play anything on this beast (XD just kiddin) I am using only 10-15% volume knob and thats super loud and crisp Excellent bass and sound quality without any distortion or muffling People complaining of muffled sound is legit, but it is totally device based, my honor phone delivers not so powerful outout so it muffles sometimes, but with my ROG laptop output is excellent Bass may be low with normal 320kbps songs, so you can use equalisers, in my case I am using sonic studio In case of movies, equaliser plays a key role, as dialogues may not sound great or clear For gaming, THX plays thumping and crisp sound! I have not used more than 50% volume knob (Wrna pakka police aa jayegi LOL) // EDIT - 14/10/2020 Quality is crisp and detailed as day one but some minor problem such as left speaker kind of stops playing and have to manually check on backside of main unit - I will fix that but still its a small issue that you should know Quality is fresh as day one and enjoying FLAC/WAV with balanced equalizer. THANKS! AND BUY THIS BEAST without any hesitation, must buy with laptop or PC setup, Thanks logitech for this heavy bass setup! I will definitely buy Z906 in future!

Mis primeras bocinas que utilicé de Logitech fueron unas Z213 y en su momento se me hicieron y siguen siendo muy buenas bocinas por el bajo precio, por lo que me animé a comprar algo mejor, unas Z337 que me gustaron mucho, pero en esas noté que, a los agudos les faltaba, pero nada que no se solucione con un ecualizador, las utilice 4 meses casi exactos y como me gustaron bastante, decidí, volver a comprar algo mejor, y fueron estas Z625, que desde luego deja muy atrás a las otras 2, tanto en potencia como en calidad, obviamente con su buena ecualización y quedan perfectas, y unos graves fantásticos, perfectas para películas y música, hasta el momento solo me dio unos pequeños problemas el cable auxiliar, pero ya no han aparecido otra vez, y en todo caso, es cambiar el cable. Las uso diario y las tengo alrededor de 16 horas diarias prendidas. En las imágenes, se observa la diferencia de las cajas de las Z213, Z337 y Z625, también las distintas potencias. En otra, la diferencia de tamaño del Subwoofer de las Z337 y Z625. Y en la última, es la bocina de mando, arriba de un Case Corsair Spec-04, El monitor es de 24 Inch, para referencia de tamaño. Las bocinas satélites de las Z337, son muy similares de tamaño. Como conclusión, personalmente las recomiendo muchísimo. También cabe recalcar que soy fan de Logitech, he probado Mouses de esta marca y han salido muy buenos y duraderos, actualmente, ocupo un Logitech G502 Hero y tengo otro G502 Proteus Spectrum, por lo que puedo decir que la marca, hasta el momento me ha salido muy buena.

After a month and a half the right speaker stopped working. I have to disconnect and reconnect to get it to work. Still trying to get it serviced. Been waiting for days for the seller to contact me after I reached out. No response.
