The Cobalt specs I read online indicate a minimum impedance of just over 3 ohms. That's a significant dip, which indicates they require amplification that delivers lots of current into those frequencies at which the impedance dip occurs, otherwise those frequencies will sound recessed compared to the rest of the frequency band. Look for amplification that doubles it's power delivery into 4 ohms for best results. Buy and read the book I referenced above for more info about how to determine the power you require for your loudspeakers, your room and your listening preferences.
