No sound from speakers

Hi, I recently moved house and left my old speakers behind. I kept my turntable (a pioneer PL-120-II) and amp (and old Cyrus Integrated Stereo Amplifier) which I had used together for a number of years and had worked perfectly fine. A friend of mine gave me some speakers to use which are Tannoy mercury mx3. I have connected everything up and, in theory it should work fine. However, the speakers won't produce any sound. After messing around with the settings a little I managed to get very faint and poor quality sound from the top parts of one speaker but no luck otherwise. 

Does anyone have any suggestions on what may be wrong? It seems unlikely that anything has broken since I very carefully transported it all.
