Twonames- well it all depends on what your receiver takes for a load,look on the back and most of the time the speaker impedence is marked.If you don,t see any then I would suggest 8 ~16 ohms.This is generally the average range,hope this helps you . cooltek Mar,15/08

Can it drive 4 ohm speakers?


If you connect 2 4 ohm speakers in series it will work. You shouldn't try a 4 ohm by itself. You'll kill the output stage of the amp.

Hi I purchased a sony av amplifier model STR-DB930 on e-bay a few months ago and I am using 3 ohm speakers from my old surround sound system. The output selector on the back of the unit is set to 4 ohms....


The lower number in Impedance specs is not a suggestion. It's a limit. 3 is not between 4 and 8.

If you don't want to buy new speakers, settle for safer low volume levels.

You're going to kill that receiver driving a 3-ohm load. HTS-style speakers aren't reliably re-deployable to other electronics. Perhaps, if you have 4 speakers and they're similar you could wire them in SERIES and present a 6-ohm load to each channel.

Re-engineering the speakers themselves is, well, don't do it. It isn't rocket science but it also isn

Pushing 4 ohm speaker systems


Officially this receiver supports only 6 and 8 ohm speakers. But for surround speakers it should not do any harm, because they are not played at full volume. But be sure to set yamaha for 6 ohm speakers.
Using only 4 ohm speakers makes the amplifier work more hard and produce more heat, that's why you can't use it at high volume.

Can I install 4 6 ohms speakers on an 8 ohms a/v receiver? receiver Sony STD HD 800 speaker system: Jamo S413 HC S5 Home theatre system,


Best Answer - Chosen by Voters An ohm is a unit of electrical resistance. You can think of it as your speaker will impede or pull 8 ohms from the amplifier that is powering it.

8 ohms is less resistance than 4ohms. So a 4 ohm speaker would require more juice than your 8 ohm.

If this is the only speaker, then that's all the resistance you have to worry about handling. If you had two of these speakers wired in parallel, then the total impedence would be up to be 4 ohms, because each speaker actually reduces the resistance in the circuit...so 8 ohms + 8 ohms = 4 ohms.

You use this information to make sure your amplifier is powerful enough for the speakers. If the speakers have too much resistance, they'll fry your amp.

Here's a good sentence to help explain, but I recommend reading the article I linked in sources...

"An amplifier designed to put out 100 watts into 8 ohms will put out 200 watts into 4 ohms. Two 8 ohms speakers wired in parallel (4 ohms total) would cause the amplifer to produce 200 watts." Source(s): http://www.marktaw.com/recording/Electro…

HI , i have onkyo HT-s3100 home theater. i would like to replace the front L and R speaker with JBL control 1 speakers. i have a fear in mind. my receiver supports 6 ohms. where as the JBL Contrl 1 is of 4...


Impedance must be matched to have a better sound performance. Althought, it has no problem b/w 4 Ohm and 6 Ohm impedance-it still work but the system may get hotter due to impedance mismatching. You can try and see how the sound goes.

''protect'' flashed continuously -worked sporadically- seems dead


That model of receiver goes into protect mode when there is really
low
resistance or a short on your speakers/wires. It does it to protect the
final drivers in your amp. Does it do the same thing with all of your
speakers disconnected? If it doesn't then you might have a problem with
one of your speakers or wires. Check your wires for shorts in them
first. That may be the only problem. That model is designed for 8 ohm
speakers, but you can go down two 6 ohms safely. I have a STR -D865 that

has been running 6 ohm speakers safely for almost 3 years now. A way to
check your speakers out is to take an ohm-meter across the terminals on
them(with the receiver unhooked). They should read anywhere between 8
and 4 ohms. Check with the manual on your speakers to see if they
correspond. If the resistance is really low, you may have a short in
that speaker. it is also possible that if they are 4 ohm speakers, you
could have damaged the drivers in your receiver. I know the model above
mine, (the 965) has a 4-8 ohm speaker selection switch on the back. The
lower models were not designed to run 4 ohm speakers. Hopefully this has

been of some help.

Onkyo TX-DS777 Problem biwiring ohm ?


"Biwiring' is not an accepted term; I suspect you mean 'parallel.'
There are three different ways to connect loads (that is all your speakers are to the amplifier); 
Assume that the speaker outputs are marked + (plus) and - (minus). 
Series - if you connect a + to a - which is then further connected to another plus + which is then connected to another minus, this is a series connecton and if doing this with speakers, each load (let's assume 4 ohms) is additive; in other words 4 + 4 + 4 = a 12 ohm load. The current flowing through each load is identical.
Parallel - In this case, all the + are connected together and then to the + on the speaker connection. All of the - are connected and then also to the minus of the speaker output. In this case, all of the current is shared and not necessarily equally; the lowest load impedance (this is a complex combination of resistance, inductance and capacitance) will draw the most current. If you have all 4 ohm loads, they will all draw the same amount of current. If you have a mix of loads, the final result will be lower than the lowest of the loads.
If a graphical representation is better for understanding, go here:
Series & parallel circuits 
In your case, if the output is specified as (for example) 4 ohms and you parallel two 8 ohm speakers, it will be a 'matched load' and safe for the amplifier. If you add a third speaker of 4 ohms, you will have a load well under 4 ohms, below the rating of your amp, and you risk damaging the amplifier if the output is not adequately protected against mismatches.
For your situation, you should look at the math on the Wikipedia link and avoid causing your amp to fail.

How do I wire 2 dual voice coil woofers to monobloc amp at 1 ohm.


the higher the impedance, the better sound quality the amp has. It's the lower ohm you have to worry about. Zero ohms is a dead short. 1 ohm isn't too far from it. 4 ohm is farther yet. The lower the ohm, the harder the amp has to work. parallel,all speakers positive terminals to the positive terminal of the amplifier and connecting all of the speaker negative terminals to the negative terminal of the amplifier. in this case Parallel wiring is connecting components to a source so that they share the same voltage

Denon AVR-1907 blinking red power button


It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.

When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.

If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.

If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.

On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".

If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.

I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.

If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.

If I can be of any further help, let me know.

This is not a pioneer vsx-454 receiver problem


I would not recomend doing this because the 4 ohm speaker is not enough to offset the 32 ohm speaker and the amp will have problems keeping up with the power consumption of the speakers and will eventully overheat and cause damage! (it will work but not well and not without risk to your amp!)
Please rate this quick response
Thank
You!
