    AMAZING sound, AMAZING price

    Wow. I have had various stereo and speaker combinations in the past, for different use-cases and under different circumstances; and for a home computer system in a bedroom that needs to be beefy yet compact, and offer quality features without being overly complicated, I really don't think there's a better offer out there. I would have paid $90 for it, easily (probably shouldn't say that - but hey, now I can buy two).Make sure you take your time, read what the inputs and outputs are, and TURN THE VOLUME ALL THE WAY DOWN (as well as turning the power off on the dial that comes with it). You woul

    Great Value For The Money

    I looked up what songs to listen to for a decent appraisal of the speakers. Here is the you tube title:"our-8-favorite-songs-to-use-to-test-headphones-and-speakers" Very interesting evaluation. Good learning tool.Anyway, my "Dell S2721D" is a great monitor. The sound is utter trash. 1.1 speaker rating. Mice running over the carpet make more noise. Thus these "Cyber Acoustics 62W 2.1 Stereo Speaker with Subwoofer"I already have a GREAT sound system hooked up to my computer. I simply plugged this set, the 3.5 mm standard jack, into my monitor.

    OK sound, good value for the price

    In the mid-90's I bought a set of computer speakers by Altec Lansing. To date, these are the best sounding computer speakers I've ever heard. They rivaled the sound quality of my actual stereo system.Sadly, this week, after nearly 30 years of faithful service and sound quality, those speakers have died, necessitating a replacement.Unfortunately, this set of speakers simply cannot match the sound quality of those old Altec Lansings. However, that isn't to say they sound terrible, either. For the price, they sound much better than I would have expected. Having said that, though, there is a littl

    Amazing speakers for an amazing price

    Wow. These speakers are IMPRESSIVE. Stuck the subwoofer on the floor of my game room, PC speakers on the desk where they should be, and this setup can make the whole dam house vibrate. Louder than I'll ever need it to be, and the bass is more than punchy enough to make me glad I'm in a house instead of an apartment - even at low volumes, my favorite songs would definitely pis the neighbors off. I'm dead serious, this speaker set is exactly the one you're looking for if you're a PC gamer or music enthusiast just trying to upgrade from them tiny old PC speakers and you're not trying to go full t

    Puck that stupid pucking puck

    UPDATE. This is the second of these I have ordered. The application for the first was a standalone (one piece monitor with the pc built in) that I custom built. I have built computers before from scratch. It worked great for that system, but this one I've had some problems with. First, out of warranty, and past the return window, the thing developed an audio problem, which I traced back to where the wires from the puck go into the enclosure for the sub. There is a modular circuit built into the plastic frame that is screwed into the rear of the sub cabinet. A wire had broken inside that, where

    Impressive bass and volume, but disappointing controls and quality.

    I bought these looking for an upgrade over my Logitech Z200s I've had for over 8 years (nothing wrong with them, just wanted something more powerful since I have a larger room after moving). I've had this speaker system for about 2 weeks now. Setup was pretty easy and straightforward. The speakers don't take up much room on my desk and the subwoofer doesn't get in the way under the desk. My initial impressions are quite mixed; I like the way my music sounds and I like how loud it can get, but I've got trouble hearing dialogue and the more nuanced sounds in games & movies as the bass and backgr
