  • Far Better Than I Expected!!
Style: Analog/Optical
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. ... show more

  • Bought a 2nd set, Great for the price, can run 2 sources
Style: Analog/Optical
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. ... show more

  • Perfect. Perfect.
Style: Analog/Optical
Man, this thing is an absolute animal! It exceeded my expectations by FAR. For the past 6 years I've had a pretty decent, yet unknown brand sound system for my PC which has worked brilliantly. It was simple, well-built, it matched my color theme at at "80Watts" it kind of packed a punch. But I've been wanting the Z623 for a couple of years now. And now that I got a new PC with an optical output, I thought it was the perfect excuse to upgrade. Yes, I got the Z625 which has the optical-in. If you're going to get this beast, and you have the option of using a toslink cable, don't bother with the Z623 and go with the updated Z625. You won't regret it. The audio quality and delivery simply can't be compared with a regular 3.5mm or RCA connection. This thing comes out clean, with a very decent midrange and also highs. But it is the base where this Z625 impresses the most. I was absolutely stunned. It makes my whole apartment rumble at mid volume and mid bass. And it is not a dirty rattly sound. It is rich, crystal clear bass that hits you in the gut. I'm no audiophile, but I've been around for a while and I do appreciate good quality sound with added thunderous bass for giggles. With my last sound system I spent weeks trying to get a good sound via equilizers and other sound settings, but I hated the echoey mids and raspy highs. This Z625 sounded perfect out-of-the-box with no sound settings. And it's great because being connected through digital output nullifies my equalizer. Built quality is outstanding. Very sturdy metallic feel. It is heavy. Logitec could've sold me this for twice the price and I wouldn't even doubt that is the cost. It is an absolute bargain! you want bang for buck? You won't find anything better than this. Period. Only negative side is that I live in an apartment with thin walls and unfortunately I am too considerate to ever be able to enjoy this thing at its full potential. ... show more

  • Very good at first, but given a little time...
Style: Analog/Optical
It's always challenging to find a "good" pair of PC speakers that sound AND look good; these check both boxes for me. I've got a large L-desk I use for my professional home office, oversize monitors, and not much free space for "stuff". While these speakers were a bit larger than I expected them to be from the site photo, they do fit in my space and give me that "beefy" feel without dominating the space. The sub-woofer has to go "way over there" around the corner so I don't kick it while in the corner and the chord length fell a bit short to connect the 2nd speaker, so a short cable extender may be required for you as well. I love the controls for ease of access as well as simple to use. I didn't need/want all those flashy RGB lights and effects, so these fit very well with my asthetic desires. These transition well after work into my gaming speakers, base has good boom, sound is crisp and clear, and easy to get my groove on. *update* Coming back about a year later, I'm coming back to remove a star. While the sound & size still are great, the volume control now squawks at every little touch. Need a little more or less volume? Touch the dial and get an earful of annoying static smash. Would really like to see a higher quality rheostat installed in here for volume adjustments. ... show more

  • Review of Logitec Z625
Style: Analog/Optical
I decided to purchase these to replace a going on 20 yrs old Altec Lansing 2.1/5.1 system. The only reason I decided to replace these were because I wanted to utilize the optical EQ feature on my motherboard and the volume knob was starting to go out (not bad for a 20 yr old system and could probably be cleaned) My initial thoughts about this system were not good. I didn't try the 3.5mm jack yet but hooked it straight to optical. Upon initial hookup the tone was very flat and too bass heavy. Before blaming the speakers I decided to mess around with the EQ settings in my digital audio. Bingo! that is what it needed. I was able to tweak it to my liking. for music. After reading reviews, I will say that if you are running this through optical you MUST use an EQ of some sort. I can turn these up LOUD and not get distortion. Without tweaking them that was not the case about 80% volume rendered some distortion. Which I will mention is pretty ear bleeding anyhow. IDK why you'd ever do that. I have them in a fairly large room its about the size of a living room nd the sound fills the room with no problem. THX: The THX feature is something the Altec Lansing speakers never had (but you really wouldn't notice). The THX features on the Logitech are quite good. You can hear a lot more distinct and directional sound in games. Overall, they are very good for the price. If you are using this system for a desktop computer id say go for it. If you are using these as a media/movie/console gaming solution on a big screen, I'd say look elsewhere. Unless you are console gaming on a small TV or in a small room I'd go with a 5.1 system As for durability we will see. The construction of the satellites seems pretty solid and the cords and knobs are beefy. the sub seems a bit on the light side but the construction is good. just a big square box with an air port on the side. ... show more
