I'm a newbie. I got a Denon AVR-X250BT home theatre amp. This is what's written on the Denon catalogue: The AVR-X250BT AV receiver powers quality home theater at 130W per channel. However on close inspection, it says Number of Poweramps: 5 Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive): 70 W Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive): 90 W Power Output (6 ohm, 1 kHz, 1% 1ch Drive): 130 W I've shortlisted two floorstanding speakers: 1) Pioneer SP-FS51 Frequency Range 45 Hz-20 kHz Nominal Impedance 6 Ohms Sensitivity (2.83 V) 87 dB Maximum Input Power 130 W Crossover Frequency 2.5 kHz Tweeter 1” 2) Yamaha NS-F51 Minimum Frequency Response 43 Hz Crossover Type 2-way Sensitivity 89 dB RMS Output Power 80 W Impedance 6 Ohm Maximum Frequency Response 26 kHz Driver Type 25.40 mm Soft Dome Tweeter Speaker Configuration 3.0 PMPO Output Power 240 W I'm confused. What am I supposed to see in a speaker? Ohms? Watts? Sensitivity? Can anyone help me out? Also, which would you choose from the two I've listed? Thank you. [SIZE=5][/SIZE]
