Review: Another 5-star Review of These Speakers -- Why Bother? - Tonight, I got a scare -- these speakers, which I've loved for the short time I've had them (i.e., since mid October), sounded tinny and thin. I checked the connections. I rebooted the computer. Still tinny. Then, it occurred to me (my mind must be slowing down) that no speaker problem would speed up the music. Aha! It was my Enounce program -- a program that lets you listen to audio at up to 3 times its normal speed. I had it set for 2X normal speed after listening to a tutorial by a drawling presenter. I set it back to 1X the recorded speed and, voila!, the music was back. So, since I had found myself more than willing to write a damning review of the longevity of these speakers, I felt it only fair to write a review of just how good they are. So, that's why I'm adding yet another 5-star review of these things. What's not to love. Their sound is outstanding. You can set the bass levels to where you want them -- and the bass is not that terrible boomy stuff of boom boxes and miserably made speakers. It is, rather, crisp and unobtrusive. The mid-range is clear. And, for all my aged ears can still discern, the highs are there. (Alas, when younger, my hearing test for the Air Force had my hearing right up there with dogs. Well, not quite. I couldn't hear a dog whistle. But, I could hear the highest tones that the hearing test provided making my line slightly above the chart. Now, I know, some of the higher frequencies are lost on me.) Volume is no problem. While those who are deaf and those who aspire to become deaf may not find the higher volumes sufficient, most who would rather hear music rather than test their pain tolerances should be quite happy with these. Could they be better? Well, perhaps I might welcome both: a) left-right balance controls and b) a remote. The former can be handled by software that's already on your computer if you go hunting for it. The latter is for those who build up a heckuva lot of static electricity while sitting on a cold winter's night. I'd rather discharge it on the remote than risk zapping the speakers. That age thing, alluded to already you may have noticed, might at any time get me to forgetting to discharge any built-up charge on the case of the computer instead. You could spend a lot more and do a lot worse (sorry Bose). But, why? My musical preferences: jazz, classical, some folk, and a handful of individuals who fall into none of these categories. So, if you're interested in hard rock or the alleged thoughts of rap "artists," you may well want to move onto another review. With computer speakers, it has been my experience that few last for all that long. But, these do appear to be made well. So, I'm optimistic that they will continue to perform well for some time to come. ========================================================================== Unrelated tip: That Enounce program is a freebie and well worth installing if you take courses or listen to tutorials or simply want to race through ads that won't allow you to skip them. It does a good job of speeding things up without making the voices sound like Mickey Mouse after he inhales helium. ========================================================================= Another unrelated tip from John Templeton (a legendary investor): The fastest way to double your wealth is to double your gratitude. Without gratitude, there is no possible perception of wealth.
Review: Blown Away by Logitech - To preface, I am an audiophile and have spent countless years at my father’s recording studio hearing some of the best studio monitors out there. I am by no means comparing computer/home theater speakers to the likeness of a pair of $6,000 Genelec studio monitors, but I have high regards for these Logitech speakers. To be honest, I bought these speakers alongside a monitor for my PC not expecting much other than knowing that for a fact they will at least be better than the speakers found in my TV, which I was using as a monitor for the longest time. When I received them, I quickly set them up and played some music from my phone. I was simply blown away at the sound quality that these speakers put out even when they were not properly setup in terms of placement. Once the speakers were properly setup, I was even more amazed. I eventually cranked up the volume somewhere around three-quarters of the way and was even more surprised that these speakers were not distorting. Ever since I set them up, I have been using them not on my PC but on my Macbook Pro nonstop and have even been able to turn off my EQ in iTunes as I feel these speakers reproduced the sound more accurately. Keep in mind that my review is based on many variables such as the size of my room, placement of the speakers, etc. But, I have found that with these speakers you need to turn up the bass knob (for me I turned it in between 1 and 2 O’Clock) to achieve a smooth low frequency response and a more overall “fuller” sound. When setting up the speakers, I recommend referencing the picture I included for placement and using a song that you know well and setting the volume to your normal listening volume and then modifying the bass knob to your satisfaction. I would like to stress that placement is one of the biggest factors for how your system will sound. Regardless, I find that these speakers are absolutely worth the money. I have used them to listen to music, to play movies, and other miscellaneous audio related tasks on my computer. There is no doubt that these speakers are THX Certified because it felt like pretty close to being in a movie theater when it came to movies that made adequate use of the subwoofer. I am even contemplating getting another pair to replace the Bose Cinemate GS Series II that is on the TV in my living room as I feel that this system is better than the Bose. I can only find one con when it comes to this system and that is if it were to be used for on a TV, which Logitech says it can be used for, there is no remote for changing the volume or shutting the unit off. Using it on a TV could lead to having to change volume by hand as most TVs have a fixed audio output not a variable one. To be fair, this is a minor fault considering that this system is more of a system for the computer than for the TV. Nonetheless, don’t hesitate buying this unit. For the price, I have yet to find anything that can beat it let alone one that is comparable.

## 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.

### ⭐⭐⭐⭐⭐ How To Resolve Power Button Static Issue (Easy)
*by M***L on January 3, 2015*

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!
