For £65 you will be getting two 10" speakers with 1000 watts each. This will be plenty powerful for any party at home or in a small hall just playing music or doing speeches with up to 250 people. 

If you are wanting them for a large venue then I would recommend adding the QCS Ksub Subwoofers for an extra £65.
