I got a pair Tannoy 609s as front:- Spec: Peak Power: 200w Freq Response: 46Hz - 30kHz Norminal Impedence: 8 Ohms Min Impedence: 5 Ohms Sensitivity: 89db Cross-over freq: 2.5kHz & a pair of 603s as rear:- Spec: Peak Power: 120W Freq Response: 60Hz - 30kHz Norminal Impedence: 6 Ohms Min Impedence: 4 Ohms Sensitivity: 86b Cross-over freq: 3.5kHz & 1 622 as a center speaker. How should I use this info to choose the right powered receiver?? Advise !!!
