Cyber Acoustics A-5640rb 54 watts 5.1 Digital Ready Subwoofer and Satellite Speaker System - Retail


I got my first set from Newegg, but the controller was DOA, so they decided to send me a whole new system instead of a new controller. I then had 1 set sitting in the closet, until that second controller died about a month later. I called CA, and they...

Great at mid-low volume, provides for an acceptable bass/guitar amp, looks loud and strong, nice highs/mids, I love the subwoofer box, mainly because it doubles as a stool or a table

despite looks the speakers are WAY too small for the enclosures, Sub distorts easily, annoying blue controller, 8 of those Acoustic Authority logos, but not a con, hisses day and night...never goes away, even louder with headphones,wimpy cables

Great product with some minor issues.


The center speaker is about 6" high and you cannot remove the stand, so for most people you have to elevate your monitor someway otherwise the speaker blocks your screen. Also, these sounded terrible with my motherboards onboard audio. I upgraded to a...

Excellent sound quality when paired with a decent sound card. Massive subwoofer, perfect for movies, long cables, easy setup. Great highs and great lows

The mid tones are absolutely non-existent. When you turn the subwoofer down all the way, all you hear is 100% treble. Constant faint hiss that will not go away

Nice Speakers


The instructions actually made sense :O (not that I needed them, but hey, that's a rarity no?) Oh, and I'd buy them again given the choice.

Pretty solid speakers. Good value for the price for a 5.1 set. Provide plenty of power for home/computer use. Good quality too

Only came with three wall mounts (should have came with 5). Sometimes it's a bit finicky, if you turn it off and on again with the remote, the sound might not come back on and you'll have to unplug/replug the power cord

Absolutely excellent


Have fun with em. I crank mine up just to see how long it take to set the wife off - generally, 10 minutes or less - loads of laughs

I've had them for more than a year, and I routinely have them playing LOUD. They really are perfect. I bought a smaller Cyber Acoustics set for the second PC and they sound good too, but not nearly as loud

Absolutely none
