Friday, November 25, – If “eight speakers” means eight pairs of speakers, then we need to clear up the confusion. You don’t mention what receiver you have but I would hope it’s a fairly safe bet to conclude any modern “stereo” receiver has two pairs of speaker outputs wired internally to be in parallel. Very little that applies to a two channel stereo receiver transfers easily to a 5. In other words, with a two channel system, when only speaker “A” is engaged, the amplifier sees a load which represents one pair of speakers. When both “A” and “B” speaker outputs are engaged, the amplifier sees a parallel connection which would then show the amp approximatey half the impedance of the lower impedance speaker of the two pairs. There are also receivers being built today which do not allow both speaker ouptuts to be active simultaneously. In this case, when you engage one speaker switch, the other switch is automatically disengaged in order to provide protection to the amplifier.

Can you add two 4 ohms speakers together to add up to 8 ohms?

February 6, Can a 6 ohm amp drive 4 ohm speakers? It’s never a good idea to driver speakers with an amp that isn’t designed for the load. If your amp or receiver is intended for 6 or 8 ohm speakers, a lower impedance can cause problems. If you do connect speakers with a lower than recommended impedance, your amp will probably not blow up immediately.

The kind that make up 99% of commercial 8 ohm amplifiers. An 8 ohm amplifier is called such because typically it performs very well with an eight ohm load attached to it. When dealing with most commercial ceiling speakers, you will find that the majority have an 8 ohm rating for audio program material (AC).

Connecting 8 pairs of speakers to 1 receiver Hook it up according to Tony’s directions and you won’t fry your amp, but you would in a parallel connection. Hooking up 8 speakers in series though would quickly clip your amp because of the 8X voltages it would be required to output. Are you using all 8 speakers all of the time? It looks like your receiver is rated at watts into 8 ohms continuously. Your current speakers are rated to take all of this power, so to get max performance out of them you would have to disconnect the other 6.

From the sounds of things though you’re not looking for insane levels, and assuming you hook them up properly as in an 8 way switch comperable to the one you have now you could reasonably expect 5 clean watts per speaker. If the speaker has an effeciency of 90db, you’d get db output per speaker, which is pretty respectable. If you can’t find a bigger switch and you want to run all of them all of the time, there is a way to hook them up safely, though a bit more involved.

Are all of the speakers 8 ohms?

Connecting multiple speakers to one output.

Speakers are devices that convert electrical signals amplified by the amplifier, into vibrations of air that can be heard by humans as sound. Speakers come in various shapes and sizes, types and models. Speaker types, based on amplification method There are two main types of speaker, based on where the signal is amplified.

Long technical answer here: It’s almost never low impedance that kills an OT, it’s too high an impedance. The power tubes simply refuse to put out all that much more current with a lower-impedance load, so death by overheating with a too-low load is all but impossible – not totally out of the question but extremely unlikely. The power tubes simply get into a loading range where their output power goes down from the mismatched load.

If you do too high a load, the power tubes still limit what they put out, but a second order effect becomes important. There is magnetic leakage from primary to secondary and between both half-primaries to each other. When the current in the primary is driven to be discontinuous, you get inductive kickback from the leakage inductances in the form of a voltage spike.

Are 8 ohm speakers any good?

I am hoping for a relatively simple answer to the below question: Am I about to blow up my amp? It’s rated for watts per channel minimum RMS power with 8 ohm loads, both channels driven. The speakers are listed as 3 ohm impedance and appear identical. They each have four 2″ woofers and one 1″ balance dome tweeter. The amp from that system was rated at 75 watts minimum RMS, per channel with 3 ohm loads with both channels driven, from , Hz.

So the ‘old’ amp I am replacing and the ‘new’ amp have A & B speaker inputs and up until right now, all 4 speakers have been traditionally wired (+ & – on each speaker to red & black on amp).

Rating Newest Oldest Best Answer: There is really no such thing as a “4 ohms amplifier”, your amplifier output impedance is approximately zero ohms. The “4 ohms” is actually a representation of the current capacity of the amplifier, it’s just expressed in terms of load in ohms to make it easy to understand what speakers you can use with it.

The 4 ohms is a minimum load which is confusing because it’s the most difficult load. It’s actually the maximum load in terms of conductance which is the inverse of impedance. Conductance is how easily electrons flow through something.

How to Measure Speaker Impedance

How to Operate 4-ohm Speakers on an 8-ohm Amp By Christian Mullen ; Updated September 15, Things Needed Speaker wires Speaker cables You can operate 4-ohm speakers with an 8-ohm amplifier if you use caution and understand how impedance works. Most modern amps can be used with speakers that have a total load at or above the minimum impedance rating. For instance, a 4-ohm amplifier can run any total load of 4 ohms or above, including ohm cabinets and speakers.

In order to calculate your total impedance, you must know the impedance of the speakers or cabinets and how they are connected. Parallel wiring lowers the impedance. Series wiring raises it.

That is two 4 ohm speakers in series will give a total load impedance of 8 ohms. Therefore you could have two speakers on each side of the amplifier (right and left). This will get more power to each speaker than running through a speaker selector switch.

Q3 What is the impedance when I combine two eight ohm cabinets? It can be done, but it will cause a mismatch of levels. This is not recommended. Q6 What is the impedance of an eight ohm cabinet combined with a four ohm cabinet? Tube replacement may become necessary after one to three years, depending on enviroment, usage and care. Generally speaking, a tube does not need to be replaced unless it becomes noisy or microphonic.

Q10 Can I use an instrument cable shielded to connect my amp to my speakers? Please use 18 gauge cable or heavier 16, 14, or Q11 Can I run my amp without any speaker cabinets connected to it? Q12 How can I obtain a manual for my amplifier?

Rating Newest Oldest Best Answer: If you don’t want a technical discussion, I’ll just say up front that a quality amplifier such as an Onkyo will almost certainly be able to handle 4 ohm speakers at nearly any volume you are likely to listen to them. Lower impedance speakers will be more stress on the amp, but not hugely more. The first guy is wrong in saying that that the amp would have to work “harder” to drive an 8 ohm speaker than a 4 ohm.

Power is power, so watts into an 8 ohm speaker is the same as watts into a 4 ohm. The difference is that the amp has to supply more current to the 4 ohm than to the 8 ohm, which is tougher on the amp.

How to Mix Different Ohm Speakers

This confusion is also a likely cause of many blown power amplifiers. This article is intended to explain the meaning of speaker impedance and guide the reader in connecting multiple speakers to an amplifier. This article is NOT intended for engineers, technicians, or even serious students of electronics technology.

than four speakers up to a four-channel amplifier, you need to concern yourself with your amplifier’s ability to handle low-impedance loads. If you ignore the way you wire them together, chances are you will fry the amplifier. watts to an 8-ohm load.

Using a higher ohm rating is not going to hurt anything. It is based on the AC resistance of the speaker at a frequency of Hz. A tone at Hz is sent through the coils, and special resistance measuring equipment determines the resistance of the coil in the speaker. That resistance is going to vary as the frequncy of the music changes. That speaker resistance is known as a “dynamic” resistance for a reason. That reason is what I just described.

Be very careful how you wire that speaker up to your amplifier. That watt amplifier can put out enough volage and current, or “sound” to say it a different way, to burn out the coil in those speakers.

Ohms on a Speaker VS Ohms on an Amp?

Single Voice Coil Vs. Subwoofers can be wired with either single- or dual-voice coils. The coil wiring in the subwoofer works with current sent from the amplifier to produce sound. Single-Voice Coil Single-voice coils will offer one set of negative and positive terminals.

Two 8 ohm speakers wired in parallel will have a net impedance of (8 divided by 2) 4 ohms. If you have three speakers, each at 8ohms, divide 8 by three to get a total impedance of ohms. If the speakers do not have a common impedance, you can use formula 1 for .

Can’t find your answer? Get the answer Jan 31, , 6: Jan 31, , 6: If your amp is saying 8 ohms, and nothing on fine print is saying it can handle lower, then whatever you do, DO NOT make it see less than 8 ohms. So the receiver watt 2 Ch with connections for an A and a B set of speakers booklet shows: Also assume if A wired serial and B wired paralleled, can I at times just play the A or just the B ie just play music in 1 room?

Truly appreciate your help! If the receiver can handle 4 ohms then it would put them in parallel to provide greater power. You can add an outboard speaker selector with impedance matching to maintain an 8 ohm load to the receiver.

4 ohm, 8 ohm, 16 ohm

I had one of those when they were new, with a V2 cab because the Stones did I was working clubs then and it was just too loud for the rooms. Yeah, I’ve heard they are really loud amps. I bought it broken, brought it to a tech, and it’s ready to be picked up.

PAGE 31 PARALLEL: When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in (hooked-up) Parallel results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance.

A Simple Guide Finding compatible speakers and amplifiers is a common issue for many people when they are looking to buy new equipment. This guide to matching your amplifier and speakers should help to answer some of your questions. If you don’t want to buy a home theater system package, but would rather a separate amplifier and speakers; then it can be difficult to know what to look for. Most of us have seen all the listed specifications – but we aren’t too sure how we go about matching the two together.

And, are there other important issues to think about? The worry is we will buy the wrong amplifier for our speakers or vice versa and we have visions of blowing the speakers the first time we switch it all on. So how much do we need to worry about this – and what are the important issues? The main thing that becomes clear when we consider this issue, is that it is not something that we should be losing any sleep over.

That’s not to say we should ignore it completely. That we shouldn’t give it any thought at all. It’s more an understanding that you could ignore it and everything will usually be fine. The chances are you would still buy a speaker and amplifier combination that would work well together. You are unlikely to find speakers and an amplifier, designed for home use, that are completely mismatched.
