I absolutely love, love, love these speakers! It's important your system is set up for six speakers but assuming it is I can say with confidence these will be the best speakers you will find in this price range. Check my reviews and you'll know I'm not gushy about products -- many people whine that I'm too harsh.

Here is an important consideration, make sure your system has the speaker jacks AND the drivers to enable six-speakers, even when you are playing a stereo recording. Otherwise you will find yourself disappointed that the sound is coming just from the left and right speakers and maybe the subwoofer. Just because you have connections for the separate components doesn't guarantee surround sound. Fortunately, most recently built computers have the technology built-in so this warning applies mostly to people with older systems. A quick and easy way to know for sure is to check to see if your computer has Dolby Home Theater built-in. It's not easy to find (Start Button\Control Panel\Sound\Playback\Speaker Properties in Windows 7) but enabling Dolby Pro Logic or Dolby Digital will allow you to enjoy immersive sound even when listening to stereo. If you don't have the speaker jacks, for example just a standard speaker and microphone jack, then you can purchase add-in cards like the Creative Sound Blaster X-Fi.


I was tempted to knock off a star for two reasons. One, I've become used to a separate "control pod" which handles things like the volume, bass and power control without having to reach for the speakers. Unfortunately, this is not included so you'll have to get used to using those multimedia buttons on your keyboard if your right speaker is out of reach and you'll have to go digging under your desk to adjust the bass level. I figure this was a tradeoff made to keep the price low. My other gripe is that, common to most surround speakers for computers, the length of the cable to the rear speakers is going to be too short to be of any benefit unless you want cables in the way. Fortunately, the connectors are standard RCA so a male-to-female extension cable will get the extra length you need if you're trying to run them in a manner that will allow you to hide the cable.

In spite of these gripes, I still think they are five-star speakers, again with the caveat that Dolby Home Theater is enabled. I say this because it really makes a huge difference and Dolby changes the sound from "decent" to "fantastic". I have not heard any of the buzzing others have mentioned, no speaker noise whatsoever, the bass sounds great - not muddy, and the highs are crisp without being shrill. I know it sounds like I'm shilling for Dolby more than the speakers but it's important that people know that once you get beyond stereo, decent sounding speakers are only half the equation; a good sound processor is equally important. It's why audiophiles obsess over their receiver just as much as their speakers.

This 75W system is plenty of power for a gaming computer, office, or bedroom but I wouldn't use it in a living room. Inputs are standard red/white RCA or the preferred green/yellow/black 3.5mm computers use. They're best used as computer speakers since you don't have a remote. Obviously these won't compare to high end THX speakers but they also don't have the high end price. If you're a gamer on a budget, I think you'll like these a lot.

Hope the review helped.

To answer other reviewers:
M. Churchill - You are right, the description is incorrect and this system uses a 5.25" ported subwoofer.
NYC reviewer - Most surround speakers do very little other than the ambient effects you described, especially during live broadcasts. Try to see if your TV has a 5 speaker stereo setting and it may give you the sound you were expecting. Try turning the built-in TV speakers off and the TV volume up to ~66% to eliminate the low volume issue. Also make sure there isn't an audio setting for TV or audio out - with some TV's it's either/or. Ultimately, I do think these are better suited as computer speakers than home theater speakers.
Ryan and others - Regarding buzzing, while it's certainly possible you got bad speakers, buzzing is almost always caused by electrical interference. Try moving the speaker wires around, especially away from power strips or electric wall-warts and see if the buzzing changes in any way. There may be an unshielded culprit causing the noise. As I write this I have my speakers maxed with zero noise.
