I have a pair of old Kg4s that I want to use as the big front speakers for a HT. I haven't bought a proper amp yet, but in the meantime I have noticed a number of Quintet pairs on ebay for cheap. Will they work as my sats? I'm thinking about a Pioneer amp to power everything, but as should be apparent I'm clueless apart from owning a honking set of speakers and an old Onkyo amp that needs replacement. guidance and instruction is appreciated.
