Whilst I appreciate that this is not expensive, it also contains very little information. I returned it for refund within 10 mins of purchasing. Has potential- what little info that is in the book is well written and clear.
Bought these speakers to connect to my PC and XBOX. For the £25 that I paid for these on Amazon I am very impressed with the sound quality. Bass is good and overall sound quality much higher than you would expect for this price. Recommended.
