I want to get a control box for my speakers so I can control the bass, sound etc. and wondered if there was one for around £20 as most of them are more than my speakers
If a software eq will work for you

Don't expect to fix the limitations of cheap speakers with EQ. You will be able to make them a tad better. When you boost 3db you are asking for twice the power and can stress and even damage speakers.
If you can't use software then a used EQ might help but as you say would cost more than you are looking to spend. Save you money and get better speakers or add a subwoofer.
This "Control box" is called "Audio equalizer", and it is plugged between the audio source (eg your audio player), and the amplifier' input where these speakers are connected. And I doubt it will cost 20 quids...
If you are looking for something to put on speaker' wires - you are looking at the wrong place.
