As you guys recommended I have been searching the local used audio market. I saw an ad in a local trading magazine with this description "Pioneer Center and rear surround speakers, 100 watts, new in box". All for $100 CAD. I called the seller and he said they are model CRS-159. Does anyone have any info on these speakers? Also, if I bought these speakers and a reciever could I use my 60 watt mini-system speakers as fronts temporarily? or would a 100 watt amp destroy them, I should include that the mini-systems speakers have an impedance of 6 ohms and have 6.5 inch woofers.
