These speakers are epic, and I'm not talking the lame internet overused phrase 'epic' they are literally awesome.
The bass, is deep, defined, and doesn't distort when turned up, they are playing now, and it feels like I am at a gig, my ears are slightly discomforted - love it.
For example, I have to now keep my wardrobe door slightly ajar due to the doors vibrating and making a noise. haha
I did own some Labtec 2.1 speakers which i bought for around 45 quid back in the day, and I thought they were good, but these are something more.
The right hand speaker has turners for both bass and volume, which is convenient as you don't have to go on your knees to the back of the sub to change the volume like on my old speakers, they also have an audio input on the right hand side speaker, meaning you can plug in your ipod with ease.
the sound is clear, crisp and loud and fills my room happily.
a smart buy, especially as they are brought down from 100 to 75, if I was you I would spend the extra 25 quid up from standard 50 quid speakers and get something special.
