    Av receiver str dg700 can I use 6ohm speakers

1 Answer

You should have no problem with 8 ohm speaker with this unit as you would with the 6 ohm speakers. The 6 ohm requirement is only not to go under that value. The only consequence of hooking up higher impedance speakers(8 ohm) to this system is that you will have slightly lower volume than with lower impedance speakers(6 ohm).

The receiver unit works fine but sudenly goes mute and comes back on between 3 and 40 minutes later. Its not an ear phone problem.


It might be over heating? do you have the right ohm speakers hooked up should use 8 ohm speakers as lower ohm speakers will cause this problem!

I want to hook two speakers on each terminal (L/R).


The correct way would be to hook only one speaker to the powered outputs and use PRE-OUT outputs to connect separate amplifier (or active speakers).

For 2 speakers to work connected to the same powered output of receiver, their impedance would need to be high enough. Yamaha receivers officially support impedance >= 4 ohm for front speakers. If you would connect 2 different 8 ohm speakers, the combined impedance could be theoreticcaly 4 ohm, but that depends on many parameters. On low volumes it should work, but could overload the receiver if used for louder volumes.

Also note that the impedance is a function of frequency (specific to every speaker), so for different frequencies the power from receiver would be devided differently between the speakers and the sound would not be good.

I have a panasonic SA AK25 with no manual.There are 2 sets of wires coming out of the speakers .how do i hook them up at the back ,thanks


you need a basic meter to ohm out the wires. most speakers ohm out around 8 ohms. some speakers have wires that can hook up to more speakers. others use an external power source to boost the output of the speaker. I would ohm out the wires and find the closest thing to 8 ohms. then with a small 1.5 volt flash light (AA) or (AAA) battery you go across the wires that you think are the load (speaker) if you hear a poping or crackle sound then you have found the wires that are the speaker wires. this would be the wires to hook up to the amp.

Just got two AR 312 HO speakers from my brother. I have a Yamaha HTR 6250. The speakers have (2) sets of cable hook up. One I assume is for built in sub woofers? Do I hook one normal and one to the sub...


do not use those speakers with that amp, those are 4 ohm speakers, which could damage your 8 ohm yamaha amp. you will have to get a 4 ohm capable amp to run the highs, and another 4 ohm amp to run the subs.

car amplifiers are currently 4 ohm, or even 2/1 ohm stable, but few, if any modern receivers can run at anything lower than 8 ohms without a danger of overheating. you may have to get a vintage amp(s), like a 1970's marantz receiver, or a 1980's to early 1990's kenwood power amp, because 4 ohm home amps are pretty scarce nowadays.

whatever amp(s)( you get, verify that they are DEFINITELY 4 ohm stable.

Does onkyo HT-s3100 supports 4 Ohms speakers from JBL(control 1)


Palaboy is incorrect. JBL Control 1 speakers are 4 Ohm 150 watt speakers. He's probably thinking of the Control 1x speakers which are 8 ohm 80 watt speakers.

If you hook your Control 1s to that Onkyo, it won't sound great and could cause the receiver to overheat and trip the protection circuit if played at high volume.

Max. wattage for speakers w/ Technics Receiver SA-GX100?


I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.

Trying to hook up jbl sr4732 speakers the highs are to loud compaird to the bass or lows. im only using a onkio with a 100 watt per speaker.


These JBL speakers are not made for a home stereo reciever. It could be part of the problem.

I do know that they have a high frequency input and a full range input on each speaker.

I am going to guess that maybe you have them connected to the high frequency input.

Are you using 1/4 inch jacks connecting to the input of the speakers?

I don't remember these speakers having a input for wires.

You may have another issue using these speakers with that reciever.

The JBL speakers are 4 ohms each, it is very likely that the onkyo requires 8 ohm speakers.

Look on the back of the Onkyo where the speaker jacks are at and see if it says anything about the minimum impeadance.

The impeadance is the ohms. Most home recievers are not designed for anything less than 8 ohms. Some are, but most are not.

Using 4 ohm speakers on a system that requires 8 ohm speakers can cause damage to the reciever. Mostly at higher volume levels, it will cause the reciever to overheat and shut off, maybe short out a channel. It pulls 2 times the amount of current thru the output transistors as 8 ohm speakers.

Let me know if this helps you or if you need more help.

you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down

Multiple speakers in same outlet


How this reciever is set up is there are left and right A and left and right B Only one 8 ohm speaker should be attached per outlet. if you exceed that your driving the channel at a much lower resistance then the units designed for and the channel will burn up.. Oh it might last a short time but bet your last dollar it will burn up the channel if you over load it. Please dont forget to rate this.
