LogitechZ623 400 Watt Home Speaker System, 2.1 Speaker System - BlackCarbon Neutral Certified by SCS Global Services

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!

My old creative I-trigue speakers were finally starting to die out on me after 5 years of pretty heavy use so I had to make a decision on which sound setup i wanted to go with for my gaming/music pc. Initially i was going to go with a home theater in a box set up, particularly the onkyo ht-s3400 refurbs that ive seen floating around relatively cheap. The problem I have is I have a small z-line computer desk and a fairly large 27 inch flat panel monitor on it. Ive got roughly 4 inchs or so on either side of the monitor to work with so i had to go with something that had a fairly small footprint for the satellite's, or kick out additional money for a larger desk. In the end I narrowed it down to these logitechs because comparative reviews showed they were very close in audio quality and volume to most of their competition in this space, the satellites would fit on my desk, and they semi-regularly go on sale for 99 bucks if you keep a close eye on amazon.After picking these up on sale in early July, I've had a few weeks to play a variety of music and games on the z623's and get a feel for the quality of the sound and build. I have to say, for 100 bucks these are definately worth it particularly if your primary focus is gaming. With the bass set at 1/2 and the satellite volume only at about 3/8 my wife was yelling at me to turn these down when I was playing WOW and Diablo III in our tri-levels basement. Explosions, gunshots and special effects all sound very good and clear right up until you get into ear bleed volume. The imaging is very good sitting 4 feet away and these speakers do a great job of providing you that feeling of being right in the middle of the action.Now for the few negatives. If you primarily listen to music on your pc these will do ok in a pinch, but your probably going to want to spend a bit more money and use an actual amp/receiver with bookshelf speakers or a powered 2.1 setup that has 2 way satellite speakers like the swan m10 or corsair sp-2500. Its not that these sound bad, just a bit flat and muted, particularly on higher notes/frequencies. I was able to play with my sound cards eq settings and get acceptable sound quality (for me) for playing music. For most people though, i expect sound quality will be just fine. Build quality, at least appearance wise is pretty average. The sub does look and feel pretty solid, with a decent steel mesh grill in front of the driver. The satellites though are constructed a bit cheaper by the look of it. They are fairly light and the plastic is rather cheap looking on close inspection. Those are really my only complaints.The z623's are great all around multimedia speakers and I am really enjoying them for gaming and casual music listening. The satellite controls for volume and bass are convenient, sound quality and volume are very good, and at the price i paid for them i think they are an exceptional value.

I've had Logitech computer speakers since ~2000 and when the set I loved so much was no longer made or affordable on Ebay, I picked these up. Purchased June 2014, these have survived numerous moves and computer builds, but still look good and sound great. I was thinking about replacing them for something flashier with more features (maybe wireless, with RGB lights). But...why would I? Still happy with the performance.This was the best $120 I've spent on my computer set up.
