can I connect a replacing 5.1 speakerset with an active subwoofer to my SONY BDV-E280 home cinema set?

This replacing speaker set is a  Magnat Interior 501 A set. This 5.1 surround set has an active  subwoofer.

If so, what do I have to pay specific attention to?

Hi,

i would advise against it, the speaker impedance for both sets are different you are likely to cause damage to the equipment, also i believe the Sony uses a passive sub in this kit, so an active one will not work.
