Product Description Logitech Speaker system Z623 with THX-certified 2.1 system delivers big, bold sound with 200 watts (RMS) of power-from your music, movies, and games. From the Manufacturer Compatibility Compare Which Logitech Speakers Are Right For You?

Review: So powerful I can only use 30% - Just a few notes: I've always lived in an apartment setting so my computer speakers have been used in up to a master-bedroom sized setting. I've owned this set for two months as of this writing. Prior to owning this Logitech Z623 set, I owned a really old set of Creative T1000 Inspire Speakers. That Creative set was a 2.1 setup with two speakers and one medium sized subwoofer. The sound was very decent and I liked the bass levels. I generally listen to music with iTunes and I set the EQ in iTunes to 'Rock' for most everything which suits my needs. This is a good, solid speaker set. I went through a Cyber Acoustics CA-3602 (extremely muffled bass, poor sound quality) and Corsair SP2200 speaker set as well (with similar issues) that just didn't cut it for me. I'm not an audio expert, so forgive me if I incorrectly use some terms in the rest of the review. Sound: Sound quality is good to me! However I feel like something is missing. It could be the "mid's" that I'm so used to with my older speakers. But compared to other sets I tried (and returned), this fits my needs. I'm really nitpicking at that, and by no means is the sound from these Logitech speakers sub par. Bass: My requirement for a speaker set was that 1) the bass has to be good, clean bass and 2) I need a bass knob to adjust the bass (sometimes I'll pump it up, sometimes I don't need so much bass). With the Z623, I now know what "deep bass" sounds like. Honestly, I could really anger the neighbors living upstairs if I cranked the volume up some more. It's pretty good bass.. and the low bass sounds great. Power: I'm considerate to people living around me in this apartment complex, so I notice that the setup is at a good, enjoyable volume with the knob turned 25% from zero. I think if I turn this thing to 50%, I'll get a warning. At 75%, I expect to get evicted. Don't ask me what happens at 100% - I have not tried and would expect to fly back like Marty did in the opening of Back to the Future. Headphone/Aux Jack: There are headphone and aux jacks on the RIGHT speaker. Useful if I want to hook up an iPad, PSP or other device where I am at home and want to hear better audio while I'm using it. UPDATE 10/22: I thought I would add that when hooking up a device to the audio AUX port, it doesn't block out your other audio. An example of this is when I hooked up my iPad's headphone-out sound to the Logitech speaker set's AUX in port. I could still hear what was going on my PC in addition to sound coming from the iPad. :) iPhone: This is a random topic to address, but my previous set of speakers used to react to the nearness of my iPhone 3GS with an annoying buzz (or, as my friend liked to call it, those drum hits from that song "That girl is poisonnnnn..."). On my Creative speakers, it was extremely loud even if the phone was 6-10 feet away. With these speakers, this issue is non-existant. Finally! You mean I can have my iPhone near me when I use my computer now? Amazing. All in all, a good set for the price for my apartment-living/gaming/music-listening needs.
Review: How To Resolve Power Button Static Issue (Easy) - 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 desertcart, 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!

## Questions & Answers

**Q: why are they non returnable?**
A: Metra 72-8104 Speaker Connector for Select Toyota Vehicles
This connector does not fit Toyota Venza. Why I cannot return?

**Q: what is the average life span of these speakers?**
A: 7+ YEARS STRONG! I purchased these back in December of 2013 in college. Speakers have moved around over 10 times, but I kept the original box for moving purposes. Finally purchased a home and these still remain as my main TV speakers. I recommend this set of speakers for anyone who wants that movie theater and thrilling music experience in their own home!

**Q: How does one extend the cable of the control speaker with the 15 pin vga cable? a regular vga cable extension didn't work.**
A: The problem with most all VGA Extension cables is that they tie pins 6,7,8 and 10 to the casing (GND). This is fine for a VGA Cable, but is not desired for an extension cable. It does not work in extending the right control speaker.

Instead, go with the Amphenol Cable Extension that wires the pins straight through. 
Lengths are available in 5', 10', 15' and 25'. Just change the last two digits when looking for your desired length.
CS-DSDHD15MF0-005 Length: 5'
CS-DSDHD15MF0-010 Length: 10'
CS-DSDHD15MF0-015 Length: 15'
CS-DSDHD15MF0-025 Length: 25'

Be sure to get a Male to Female connectors.

**Q: what are the speaker and sub dimensions**
A: The sub woofer is 10" deep, 12" wide and 11" high. The speakers are 5"  wide, 5 " deep and 8" high. Meas. are aprox. Hope that helps.

If the speaker goes into standby, it needs to be turned off and the again on, or you won't get any sound, even if you start for example Youtube.
