Look for used ACI Sapphire III speakers for the fronts and ACI Emeralds for center/rear. They may be slightly over your budget used but are great speakers for HT and music.
While I would not play these at concert levels (115 db) they can play uncomfortably loudly in a medium room with the only damage being your hearing.
