Hi, Forgive this "newbie" question but... I have some old speakers from a Sony DAV-S300 surround/DVD system (the DAV-S300 having died some time back). Would it be possible to use these speakers on a new AV Receiver? I am in the market for a good entry level amp and am considering the SONY STR-DH820 amp, but am not sure I could run to new speakers. My main concern is the DAV-S300 subwoofers which is passive. Is this a problem. If the subwoofer is a problem could I still use the other speakers and just purchase a new subwoofer? Would appreciate any input. Thanks!!
