  • Definitely an improvement
Style: Analog/Optical
If you're expecting high quality studio monitor sound, you'll probably be disappointed. But if you're used to the typical small desktop computers, these will sound great. The volume can get really loud if you're within 5 or 6 feet of the speakers. Once you get 10 feet away or so, the volume doesn't seem so loud. For gaming these are pretty hard to beat. For hooking up to television is a smaller room they work great. For a really large room the speakers aren't that loud. I wouldn't say they are near field, but they don't have great range. When sitting close, the sound is pretty sound. The bass is above average. You will definitely hear the bass difference if you're used to smaller/cheaper desktop speakers. They are fairly sturdy. They have a good modern look to them. They are easy to setup. No special tools or drivers required. I would recommend these for a gaming computer. I would say they are a good value. They aren't the greatest, but they are definitely worth the price I paid for them. ... show more

  • How To Resolve Power Button Static Issue (Easy)
Style: Analog
EDIT/NOTE: After about a year, these speakers developed a loud static/crackle noise when you'd touch the power button. Sounded like it was almost shorting out whenever I'd go to turn it on. (And bear in mind, that I dust frequently and keep a very clean house). Just wanted to let everyone know, if your speakers develop this problem, it can be rectified by simply taking an aerosol can of electric contact cleaner; use the little "straw" that comes with the cleaner; unplug your speakers from your outlet, and spray the contact cleaner all around the power button, directing it into the space between the power button and the case, all around the circumference of the button. Spray it good; give it a few minutes to dry, and plug your speakers back in. Voila! Good as new. These speakers produce the highest-quality bass that you will ever find anywhere even near this price point, hands down! Tight but full bass which will not disappoint. That being said, while the overall sound is definitely high-quality, it is not audiophile quality- but you were not eriously expecting that for this price, were you? Then again, these were obviously meant to be computer & A/V speakers (Although I use them for bedroom music speakers), so they were engineered to fill that niche, and they EXCEL at that purpose! I'm reviewing them more so from the perspective of music speakers- so plrease bear that in mind. My only real complaint, is that highs and certain mids can be rather recessed. That's it. If they had merely added a tweeter to each satellite, these speakers would be PERFECT. Even so, they still sound great- and the average user who listens to popular music probably wouldn't even notice. And that being said, they STILL sound better over-all than anything you can get anywhere near this price point which will retain powerful and quality bass. A few other niceties: The on/off button; Volume control; and bass level control are on one of the satellite speakers- so you can control everything conveniently and quickly, including the subwoofer. A headphone jack, and a 3.5mm input jack are also located on the same satellite- so you can plug your MP3 Player in easily. There is also a 3.5mm input on the sub, and R & L RCA input jacks on the sub. The actual components are very well-built and of nice quality. Heavy; not cheap and cheesy. And the sub is built sturdily and heavy enough to take the pounding of the bass that it is capable of producing, with no rattles or other annoying noises. The system works well at all volumes, from loud, to barely perceptible- including the sub, which still does it's thing, even at the lowest volume, and maintains the bass in proper proportion, even at very low volume- and thanks to the bass control knob, you can choose to have virtually no bass at all...or overwhelming bass- or anything in-between. You can tailor it just the way you like for your preferences and listening needs. The only slight caveats: The cables which connect the satellites to the sub are about 6' long. If you want to place the speakers further apart (Their placement in the room, and the orientation of the sub can make substantial differences in the sound) you'll have to get extensions. A standard RCA extension cable for the left satellite can be had for 6 bucks, but the special cable needed to extend the right cable (which contains all the controls) is rather expensive- ranging from 25 to 50 clams or more, depending on the length you need. Considering the qualityu of these speakers though, and the price for which you can get them here on Amazon, that doesn't bother me as much as it otherwise might- even if you spend 40 bananas on an extension, these speakers are still a great deal, and will still sound better than anything you can get for the combined price. Only other minor complaint: There are no keyholes or any other attachment points on the satellites for wall mounting. To be fair thopugh, most other systems designed primarily for computer use do not have such features either (Withj my old speakers, I drilled my own- without even taking the speakers apart- and I got lucky, and didn't hit anything inside...but I'm not willing to take that chance with these- so I made little shelves for the satellites, and velcroed them to the shelves!) That's it. Summary: If you're looking for great-sounding speakers for any purpose, with amazing bass, and are not prepared to spend several hundred bucks, get these! Period! Others aren't even close at anywhere near this price. There's no competition- these are simply the best you can get at this price point- case closed; no regrets! ... show more

  • Super value
Style: Analog
The Logitech Z623 speaker system was purchased to supplement a recent new computer purchase. While considering a couple of other options including more expensive stereo speaker options (Audioengine options being top among them)—size, cost, adjustment knobs on the front speakers, and inclusion of a subwoofer as a package deal took precedent. Personally, if I want superior sound—whether listening to music or playing games—I often put on my favorite headphones—or listen to FLAC files over a network routed to a main multi-channel listening room—so computer sound at the desk is less critical. That said, I was surprised with this Logitech system. It is not perfect, but for the price point, it offers significant value. First off, installation was standard and intuitive—both hard wired and with the Windows 8.1 audio connections—not much to know or to study. All connection cords are long enough for this user with the subwoofer under the desk and the stereo fronts above. There is an on-off button along with volume and bass adjustment knobs. On the side of one of the front speakers are connections for headphones and a portable music device input. The speakers look pretty nice on the desktop without taking up lots of space. The sub, while under a desk, looks great and if located somewhere more visible would impress. All speakers seem solidly built, and indeed the package it arrived in was about 20 lbs.—thanks to Amazon Prime for free second day delivery! Starting with some music, the front speakers seem pretty flat with nothing exaggerated in the treble or middle end. The size of the fronts precludes any significant independent bass. The bass is a bit heavy at the default middle knob setting—and while not super tight or punchy—it definitely makes itself felt. For most purposes, bass is to be felt and if you want desk shaking, foot stomping, and explosion romping fun the subwoofer delivers to an almost surprising degree considering the approximate 12x12x17 size. The adjustment for bass provides a nice way to tailor things to personal taste all the way up to desk shaking. Playing games with mid-range vocals showed these speakers were very good in this range with precise clarity. Spatial orientation without any surround speakers was also very good with environmental cues, like birds chirping in the forest, seemingly all around the listener. Of course many of these things do benefit from literally sitting right in front of the speakers. In all, for the price, these speakers are a great value—you would be hard pressed to find better—unless you spend hundreds of dollars more. ... show more
