can i connect 8 ohm speakers to a 6 ohm a/v receiver?

Answer 1

You can get away with it, but don't crank them up too loud or you could damage your power amplifier.

As for hearing, the human ear is supposed to hear a change in one dB. 1/2 to 1/4 dB is actually more realistic. But the increase in dB for doubling the power (100 to 200 watts, for example) is 3 dB...so we can actually hear a smaller change than stated by Christian above.

Answer 2

Actually, connecting 8-ohm speakers to your 6-ohm amp is safer than using 6-ohm speakers. The 8-ohm speakers will draw a little less power from the amp, but not much. The difference is too small to matter in any case. (The ohm rating of a speaker applies to only one frequency, usually 1kHz; at other frequencies, the impedance will be very different. Also, the accuracy of the impedance spec isn't that great; your 8-ohm speakers could actually be closer to 6, or higher that 8.)

Answer 3

Of course you can. Speakers are speakers, basically you can connect any speaker to any amplifier.
The downside is because your reciever is rated at 6 ohm, using speaker with higher impedance (8 ohm for example), will reduce it's maximum power below it's published specifications.
For example if your receiver has 6x100W maximum power at 6 ohm, with 8 ohm speakers it can only push maybe 6x70W.
You won't notice that small difference in power, human ear can only detect SPL difference is the power is doubled or cut half (for example 100W to 200W). This may happen if your speakers have very high impedance, let's say 16 ohm.
Hope it helps

Answer 4

am not a technical person to answer this , but i can assure you that your amplifier is going to burn off.

Please connect the matching ohms if thre is difference its certainly going to create problem.
