Advice on old "FISHER" speakers

[TENSE]

Today i was wondering and cleaning my garage when i stumbled upon a pair of old stereo speaker my dad use to own in the early 90's. The brand is called Fisher and the model number is stv-9628. I hooked them up and they sounded alright for some early 90's stereo speaker, of course they did not sound as good as my Reference 82's, but They sound good nevertheless. Now my question is, can i use thees speakers for surrounds, so i can purchase the the rc-62 and complete my 5.1 system? or should i purchase some up-to-date bookshelf speakers? this would save me a lot of money by the way. The speaker also have some damage to them like one of the 8 inch woofer has a dent, but sound no different than the other which does not, and still sounds great. here are some pics; thank you all.
