Inside Your Shirt

Here's the part of the review where I receive my pay. See, I go on and on about how I am so much more qualified than that guy and that guy over there and that girl because I did this and that and that too. It's an ego stroke, you see. That's the pay. I'll send mine to charity. 27 years on the air in commercial broadcast radio qualifies me .. not one tiny bit more .. than you. You have two ears. I have two ears. And there we go. This is a speaker of the times, 2018. Technology. What do they sound like? They are very "close", very IN YOUR FACE. The sound field is intimate. Now, they back off and lack just a little bit on the high end. But the bass is unstoppable. Again, speaker of the times. If your scene is "Yo Baby Yo Baby Yo Baby Yo", it's all you could ever want in life. However .. if you like a little Jim Croce and America, it's not bad there either. Because the mid-range is so vibrant and colorful. And that comes in for what I was saying about "close". It's the middle part of a mix that carries intimacy and presence. These speakers have that. I would GUESS that Rush fans and maybe Genesis fans would be a little disappointed here .. simply because the complexity of that music needs a strong high end to explain itself. Neil and Phil would love it, though. The kick drum is definitely in the house. No, that's not a modern term. I mean .. it sounds like the kick drum is in your house. Really really. For the price of the speakers .. it's absolutely ludicrous that you can get this much fidelity. The value here is enormous. Highly, highly recommended.

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.

Shop around and read reviews on this Item

For 100$ I'm absolutely amazed at the sound output. Highs and mids are very crisp. Bass will hit you in the chest at high volumes. It does take a little adjustment on equalizer to get perfect sound but then again what speakers don't. Would highly recommend this product to anyone looking for the best bang for their buck in the 100$range. I bought for my PC but will more then likely buy another for my tv in separate room. Update: After almost 2 weeks it has developed the high pitch noise in right speaker as described in other reviews . If your not right next to the speakers you don't notice it or at high volumes. But if you are like me and use them at a computer desk with the speakers right next to you , you notice it unless volume is medium to high. Rather disappointing cause i feel without this issue they would be a very nice setup.

You will find you need to turn things down for once.

First off, let me just say going in, I didn't think I was going to be too happy with these, however the price was right and I needed new speakers and didn't want to go through the trouble of getting a full surround sound system hooked up. Now having been using these for a few days now, all I can say is wow. Initially this started because I have been using speakers with my pc I actually got from work about seven years ago and they worked just fine, in fact they still work just fine. However, as I get older I notice that just fine is no longer working for me, as my ears age along with the rest of my body sometimes the low end gets hard for me to make out, and this happened to me while I tried to watch a youtube video. I turned my speakers all the way up and turned the controls on the video all the way up and I still could not really make out what was being said. So I knew I needed something better. They are labeled as "Powerful THX Sound" and boy are they ever powerful. For the first time I'm finding myself having to turn things down because they are too high, and I am truly happy that I picked these up. If you are like me and its getting harder to make things out, these are a really good pickup. I hooked them up to my PC, and PS4 through an external sound card and they are just fabulous speakers. The subwoofer on the floor pounds out bass that is impressive and with 400 watts of power, hearing things is no longer a problem.
