Probably OK, depends on the amplifier design. You have to be careful, especially at higher volume, the lower impedance will allow too much current to flow and burn up the amplifier.

How use pa system


All the 8 ohm's means is that you need to use an 8 ohm speaker for optimum performance. That is what the radio is set up for. Most small PA speakers for auto etc, are 8 ohm's.

Speaker audio .


The reason is the system is likely designed to use 8 Ohms and 4 ohms will cause a problem like you describe. Either find 8 ohms speakers or a 4ohm to 8 ohms matching transformer.

The speaker has a low power output


The output of a speaker primarily depends on system design (obviously) However, perhaps you have sourced a replacement or 'upgrade' speaker for an existing system. In that case, perhaps you have an impedance mismatch. If your amplifier is designed to drive, say, an 8 ohm speaker, and you connect a speaker of 16 ohms impedance, then your sound will be softer. On the other hand, you may have connected more than one speaker to one power amplifier output. If you connected in series you add the impedances. If connect in parallel you work out the impedance using this formula:
1/Answer= 1/Speaker A impedance + 1/Speaker B impedance + 1/Speaker C impedance etc. So if you connect three speakers in parallel, each of 8 ohm impedance:
1/Answer=1/8 + 1/8 + 1/8 = 3/8
3X Answer=8
Answer = 8/3 = a little less than 3 ohms.
Reducing the load like this makes the sound louder, but risks distortion or even damage. Check your manual for amplifier tolerances. Cheers, Don.

I am installing a MDS-6a system in my home Must I use all 8 ohm speaker thru up the house ? Can I use 6 ohm ,can I mix ? Thanks


That depends on the amp. If the amp is rated at 6 Ohm's you can, but it's best to stick to the same ohm speakers. If it is rated at 8 Ohm NEVER connect 6 Ohm speakers. The golden rule you can go higher but NEVER lower than the amps rated output. So if it says 6 to 8 ohms on the amp you can use the the 6 ohms speakers.

I just purchased a yamaha RX-V767 receiver. I have a polk surround sound speaker system 5.1 that have an impededance of 8 ohms. The receiver has an impedece adjustment knob on it. would it be safe to...


No, you don't want to do that. The Ohm output on the amplifier must match the speakers. Run 8 Ohm speakers on 8 Ohm and run all your speakers on the same impedance (Ohms). Your gonna burn your amplifier up if you run different impedances.

Appropriate voltage for PS-57


Speakers don't use a voltage level to determine their usage- they use an "ohms" rating, like 4 ohms or 8 ohms. Ohms is written as an omega symbol. You have to match the ohms rated output of the computer to the speakers, or you can either blow the speakers up, or overload your amplifier and burn something up (usually a transistor). The power rating is also used to match components (expressed in watts, or the letter W). You can use a higher power rated speaker with a lower power rated amplifier, but you have to be careful of the opposite case. At some point at the upper end of the volume knob, you will draw too much current and blow the amplifier. Most people do this because it used to be that loud, etc., but in reality, you will never get the same volume with a lower power rated speaker system, and trying to will jepeordize your amplifier. I searched the net, but noone had any technical info on them, but I did see some pictures. My guess is that they're 8 ohm speakers with a very high power rating. Just make sure your amplifier is rated 8 ohms too, good luck! (P.S. if you're amplifier is rated 4 ohms on the output, I would recommend getting an 8 ohm output amplifier on ebay, in the event the speakers are 8 ohms) Hope this helps.

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…

What do you mean by the subs should have more watts than the amp.and subs mean woofer ? actually i dont know any thing abt this. what is 8 ohm stereo, 8 ohm bridged,4 ohm stereo. etc etc...?


If your planning on using a stereo system in your car or home you need to follow some rules otherwise your just wasting money. The watts of a speaker means how much power it can handle. The higher the number the more power it can handle, and usually the louder it can get without distorting. If your amp has more power or close to the wattage rating of the speaker you will blow the speaker, it can even get so hot it ignites. The amount of ohms is the electrical resistance the speaker provides. House speakers usually have 8 ohms where car speakers tend to use 4. 8 ohm stereo means your left and your right are separate channels and each speaker has 8 ohms. 8 ohms bridged means you bridge the left and right channel to increase the power output of the amp and you have to use either 1 8 ohm speaker, or 2 4ohm speakers in parallel to prevent damage to the system. Same goes for 4 ohms. If I remember correctly you want your sub(woofer) to have a wattage rating 20% higher than the amp. Remember if the speaker overheats its no good, but most amps if they overheat they just shut off until they cool off, but only if they state they have a thermal overload protection.

Adding speakers to Fender Passpost 500 Amp system


If you add 8 ohm speakers in parallel then you would be running the amps into a 4 ohm load ...which will overheat and possibly damage them ...... if you wire series then the amps would be loaded to 16 ohms ...which would be ok ..but you will only develop 70 % of the total output power
IE a 100watt would be down to 70 watts
much better to add some seperate powered speakers

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).
