For the love of God please do not buy these!!!

They don't go that loud at all, the bass is rubbish, don't expect any booming ground shaking from this unit, you simply won't get it. The 2 small speakers sound quite nice, very crisp, however these distort when you turn them up too loud. The small wired remote is very cheap looking.

Another point to note is that the small speakers are very light. They do look quite nice though but what's the point when they sound awful.

For £10 more go for the decent x-230's. The difference is amazing. The x-230's will blow the room down with the amount of bass they produce.

I have read reviews really praising these, especially for use with an xbox 360 or PS3, stating they give good base and loudness. These speakers are not worth a lick. I know we all have our different tastes but really DO NOT BUY THESE. Spend a little more and get something a lot better. They sound rubbish for music, rubbish for pc and video games oh and rubbish for dvd's too!!

These speakers are well worth the money and have a nice, clear and crisp sound. Be aware though these speakers are not extremely loud however they are reasonably loud. These are ideal for a small to medium size room.

I just got these speakers...and they are great. The sub is smaller than i thought...but the sound quality is good (which is the main thing). Also the 2 speakers look good on the desk.

 Definately worth the money, if not more.

These are very nice sounding speakers that look great and are fairly cheap for what they are. I recommend them. However, a point that doesn't seem to be noted by other people is the lack of modular plugs. The control box is attached to both the subwoofer and the wire to the pc. This meant I had no choice but go underneath my computer table and force the control box through a small hole. It would have been easier if I could unplug everthing and dangle the wires through instead. However, this is but a minor issue for me and is mainly about practicality, for the price I payed this is expected. The sound is very good, the base is strong and powers clearly downstairs. Ironically, the bass of the tweaters themselves is astonishingly good, quite loud but not overbearing. Not something I expected, the subwoofer compliments them brilliantly. If there was a wireless version of this set up I would definately buy them!

 Great. Would give 6 stars if I could.

Got these for watching DVDs and listening to music on my pc.
Good clear sound, and definitely loud enough Very easy to set up and the volume control is a neat touch as it sits neatly under my monitor and can be used to connect headphones which means you don't have to reach behind pc case to plug them in.
Probably wont get any higher quality product for this price.
Would definitely recommend. *****
The speedy delivery was good and they came well packaged/protected.
