ok, so i was just messing with my surround sound at home, and i noticed that most of my speakers are 6ohm impedance, but it says 8 ohm impedance on the receiver. what is the difference between 6 and 8 ohm and how does this affect my surround?

is this a matched set you bought together, or all separates? most home audio is 8ohm and most car audio is 4 or 2ohms. the impedance is like the resistance, it is the load that the amp is seeing and yes it affects the output. if an amp is rated to be 8ohms stable and you try and lower it too much it will produce a worse signal and overheat or fry the amp. where are you seeing 6ohms on your speakers? i have never seen any like that, what is the brand and model? going from 8 to 6 shouldn't be a big deal but it isn't ideal for your receiver.

it's all piecemeal. I got everything for free. it's 4 stereo speakers, 1 home audio one, and a computer sub-woofer running off the center channel. (no sub channel)

well i wouldn't worry too much, but would still be looking for a good deal on a matched 8ohm surround speaker set. what kind of receiver is it?

 

[Shimrra]

Teac.

a 6 ohm load shouldn't be a problem, just watch how far you turn up the volume. the amp will try to push out more watts than it is supposed to. i had a stereo in the 70's that was set up that way. i fried the speakers more times than i could count. but it was a monster receiver with 165 watts rms per channel at 8 ohms, so i figure it was around 200 watts with 6 ohm speakers.

lol i turn this up to 50% and i can hear it in my basement like it's in the same room.
i had it to 100% once, i went to my driveway and then ran to turn it back down because it's clear as a bell outside lol

Too bad you're running a sub off the center channel. The center channel is for on screen mid-range sound - mostly dialogue. Is the sub powered with its own amp? If it is, and if it has spkr level inputs, run L & R from the AV rcvr front to your 2 front speakers. Run L&R rear from the AV rcvr to the sub, set the crossover to 120-180Hz, and use one of your full range speakers off the AV rcvr center channel. Set the AV rcvr mode to 5.1...If everything's right it will sound waaaaaaaaaaaay better.

i agree that's what i would do in your situation.

that just went WAY WAY over my head.
center right now sounds the best because the sub is playing everything and the speaker is the only 8 ohm in the system.
i want to fade the center and bring up the mids in the surround if anything! lol

but the sub is a plug in one. it's made for a computer and it would power the whole system, i only have the sub though.

and there are no speaker level inputs, just fade and balance.
the settings are "dolby pro logic" "dolby 3-stereo" and a normal stereo setting.

this reviver is probably from the mid-early 80's so it's pretty simple
