The only relevant speaker spec is the impedance. As you probably realize the Pioneer SX-255R recommends 8 - 16 ohm speakers.
Four ohms is on the hairy edge of too low. You could certainly try it but if any strain or excessive volume is used you could see something go poof!
The low end of 120Hz says don't push the bass to them.
