Can I connect my 4 ohms speakers Fr,Srr,Ctr and active subwoofer with the av receiver which has the following specifications.
AUDIO SECTION
Maximum Power
Main Channels 80 W + 80 W
Centre Channel 80 W
Rear Channels 80 W + 80 W
Minimum RMS Output Power (6 ohms,1 kHz, 0.1% THD)
Main Channels 60 W + 60 W
Centre Channel 60 W
Rear Channels 60 W + 60 W
High Dynamic Power,Low-Impedance Drive Capability Yes
Dynamic Power/Channel 6 ohms 75 W
4 ohms 95 W
2 ohms 105 W
Input Sensitivity/Impedance Phono (MM) 2.5 mV/47 k-ohms
CD 150 mV/47 k-ohms
Frequency Response 10–100,000 Hz +0, -3 dB
Total Harmonic Distortion (1 kHz)
CD (Main Sp Out) 0.06%
Signa-to-Noise Ratio (CD, 250 mV) 100 dB
Tone Control Characteristics

I am a newbies and I have no idea what does this specification (in my previous post) say. ( have only a little knowledge about audio terms)
Hope someone can help me! |

Charles - Sounds like you can drive the 4 Ohm speakers OK. Check the responses under "Amps" at "Harman Kardon" to see if that answers any of your questions about specs. Ifnot come back and I'll try to help. |

Charles:
Look on the back panel of the receiver in question. There will be a notation near the speaker output terminals telling you what impedence levels the receiver will tolerate. Although the spec sheet suggests it can handle 4 ohm speakers, I wouldn't bet the mortgage on it--that is probably with only one channel active! However, the back panel will tell the real story and I am guessing that if you have more than two channels connected, it will insist on 8 ohm speakers all around.
BTW, your receiver specs read like a Denon, and my Denon did not tolerate a 4 ohm load (can you say "shutdown"!). |

charles,
It looks like it is designed to cater for 4 Ohms; the spec even gives the power output for 2 Ohms. This is something to ask the dealer; he should be willing to take responsibility for getting that right.
You have every right to be confused. When a maker's spec says "Minimum RMS Output Power (6 ohms,1 kHz, 0.1% THD) Main Channels 60 W + 60 W" etc. then we are all at sea without a paddle. The minimum output power has to be zero. Ideally, you would not have to switch it off to get that. |
