These switches allow you to route a single audio source and sometimes more than one through a switching system that distributes the audio to various speakers or speaker pairs throughout the home. In this way you can choose, or select, which areas of the home you want to have audio. While simplistic, there are things you want to take into account when using these devices so that you use them properly and also maximize the way you distribute audio to various speakers in your particular application. Typically, a speaker selector switch is placed after an amplifier or AV receiver, so that it can take a source—be it a radio, iPod or other streaming music source—and pass that on to speakers throughout your house. These are typically passive devices intended for use with already-amplified speaker-level signals. Options and Controls Speaker selector switches can range from handling two pairs of speakers all the way up to 8 pairs of speakers or more, but they all work in basically the same way. They turn on and off pairs of speakers in the system, and they may or may not adjust the volume for each pair. More sophisticated models may even support more than one source, serving as a sort of matrix switcher for routing any audio to any pair of connected speakers.
Would like to hook it up to some decent 6 ohm speakers I have but the back of set says 8 ohms. Any problems on this low a power or suggestions? Two equal impedances run in parallel will yield half the impedance of each or 3 ohms worse than 6.
Re: receiver to speaker impedance matching After rereading your question, using an 8 ohm speaker on an amplifier rated for a 6 ohm load should be no problem. Going to .
Originally Posted by Scottnot Older tube amps were designed with a specific output impedance; for best distortion free audio it was best to use speakers that “matched” the output impedance of the amp.

Yes, lower impedance speakers will draw more current and so the amp will run hotter or may overheat if the impedance is too low. However, since lower impedance speakers will draw more current at any given volume setting, they tend to “play louder” than higher impedance speakers. Most modern solid state equipment should have no problem driving 3 or 4 Ohm speakers through “normal” volume ranges.
When you attached a speaker that matched the tap, the output tubes would “see” the load. Solid state amps do not have output transformers, the approach is to make the amp’s output impedance as low as possible. That does not mean you can safely attach a speaker load of less than 1 ohm. Drawing excessive current is what damages an amplifier. My guess a speaker that is rated at 3 ohms was sold with an amplifier and the amplifier and speaker are matched.
I would advise anybody caution before hooking up an excessily low impedance speaker to a random amplifier. Having said that, many consumer amplifiers have protection circuits that will clamp the output current aa it approaches a maximum value.
Will 8 ohm speakers work with a 4 ohm amplifier
I get a lot of people asking how to wire 2 speakers up together and maintain the same impedance as one of the speakers, for example taking 2 8 ohm speakers with the end result as an 8 ohm load. It is impossible – your only options are to wire 2 8 ohm speakers in parallel and get a 4 ohm load, or 2 8 ohm speakers in series and get a 16 ohm load please note that things of this nature are possible with cross-over networks, however, only if the 2 speakers will be responding to different frequencies.
It is possible to maintain the impedance with 4 speakers, but not with 2. Can I use a Resistor in place of a speaker to even out the impedance?
When a manufacturer states the power output of an amplifier, they provide the impedance of the speakers as a reference so that buyers can compare ‘apples to apples’. They are not inferring that you have to use 4 ohm speakers. The power output into an 8 ohm load will be a little less but I doubt you.
Next 6 ohm speakers, 4 or 8 ohms on receiver? I have bookshelf speakers from an old mini stereo system as my front speakers, they are rated at 6 ohms. My receiver has a selector on the back to switch between 4 or 8 ohms, I’ve had it set to 4. Is this the best selection? I understand ohms is the rating of electrical resistance, which in terms of speakers would mean If that’s the case am I correct in thinking the receiver should not be putting out more ohms than the speakers can handle?
The 6 ohm speakers in question came with a Sony mini system I got about 3 or 4 years ago. Here is a picture of it. It’s not identical but the speakers are the same. Also the receiver is a Sony receiver. I know Sony don’t make the best products, blah blah blah. This is why I’m replacing them. I bought it from eBay around 2 years ago. The two front speakers are 6 ohm.
The Marketplace for Musicians
This makes the GTO an ideal match to systems powered with head-unit or factory-amplifier power levels, or even with many of the GTO Series amplifier combinations to help keep up with systems that feature one or more subwoofers. And its great power-handling specifications also increase reliability over the lifetime of the speaker. With an effective increase in cone area, the speaker radiates more air. Also, the carbon-injected cone material produces a lighter and stiffer cone.
newbie – I have a watt 2 ch receiver that has a 8 ohm impedance. I wanted to use with 2 sets of speakers (2 different rooms). Concern is that one pair (A set KLH A) is listed as ohms/5.
In my case, I also have the added burden that two of my main contributors are or were speaker manufacturers, some of whose products you will see as References below. Other associates are distributors of speaker lines. Accordingly, I made the only decision I could: All the choices in this category are mine alone. What I say to those who question my objectivity is; please closely read the rest of the References first to see my consistency and sensitivities, before making judgements on the few choices you may be understandingly skeptical about.
Any final and true judgement concerning these or any specific components requires a personal listening session with them. If this list inspires such an event, it has been a success, no matter what the ultimate result. Behind the Curve This is the component category in which I believe that I am most “behind the curve”. While I am very confident that all the speakers that are included deserve to be there, I am just as confident that there are at least an equal number of others that are missing.
I have heard some of the “missing”, but I haven’t yet made the in-depth evaluations and comparisons that are a requirement for their inclusion.
receiver to speaker impedance matching
Yeah, the math is wrong and there are some other problems. The below are gross simplifications. If you want 1 watt into an 8 ohm load, the voltage must be 2.
The receiver has 4 assignable digital audio inputs (including 2 coaxial and 2 optical), analog stereo connections for CD players and recorders, and a subwoofer preamplifier output. It also features a set of channel audio inputs for channel DVD-audio, SACD, or Blu-ray analog audio connection options.
I always have to remind myself to double check which socket to plug the speaker cable into on the back of my Ampeg GVT15 head as I have a 2 x 10 cab with 2, 8 ohm speakers wired in parallel and also have the Ampeg 1 x 12 cab which has a 16 ohm speaker. Having only skimmed through the article briefly I’m at work at the moment! So, am I right in saying that, as my 2 x 10 cab is wired with the 8 ohm speakers in parallel giving 4 ohms impedance, this will be louder than if I had them wired in series which would give the cabinet a 16 ohm impedance rating?
This seems to be what’s being said in the article but am I misreading it? Del that amp has taps for 16, 8 and 4 ohm speaker cabinets so just select the appropriate one for the cab type you’re running it through. I’m no amp tech but my understanding is if you’re using the correct amp settings the volume should be roughly he same at 4 ohms in parallel as it is at 16 ohms in series.
4 Ohm Speaker with an “8 Ohm Minimum” Reciever
Subwoofer recommendation for the Onkyo Quote: Originally Posted by rbinck There may not be a good answer to your original question of why would a speaker not intended to be sold as part of a system be made 6 ohms vs 8 ohms.

Jan 01, · You can wire both speakers in parallel for 4. You’d really need two 16 ohm speakers wired in parallel for 8 ohms, or two 4 ohm speakers wired in series for 8 ohms. There’s no problem mixing different wattage rating speakers, but you have to remember that you can’t use more than double the power of the lowest rated one.
What does that mean? Well if you know what voltage and current and power are, then one way to look at impedance is how much of the power you are putting out is in voltage and how much is in current? That ratio is one interpretation of impedance. The ratio of voltage to current coming out of power tubes is relatively high. But you need lots of current to make a speaker move, so you have to trade some of that voltage in for more current.
That’s what a transformer does. How much do you trade in? The answer to that question is chosen by the amp designer and is your amp’s rated output impedance. That means your amp is designed to put out its rated power with a specific ratio of voltage to current. The amp will pretty much put out how much voltage it’s putting out in any situation, and it’s designed to put out a certain amount of current along with that.
Designed meaning that if it is not allowed to put out all the current it can, then you won’t get the full rated power, meaning your sound will be quieter and maybe less clear.
Can you use stereo speakers with lower Ohms than a receiver has
For frequency response, three measurements are shown: Ideally, the former should be more or less flat, and the latter should look the same but should tilt down slightly as the frequency increases. The response of the UF5 is quite flat overall. Because of that on-axis dip at 7. That dip is narrow enough, shallow enough and high enough in frequency that I doubt it would bother anyone.
The one anomaly I see in the measurement that I expect would reveal itself readily to the ear is that peak centered at 2 kHz, which might make the speaker sound a little brighter but would probably also have the positive effect of enhancing voice intelligibility.
May 21, · 4 Ohm Speaker with an “8 Ohm Minimum” Reciever. The NAD Manual states that the speakers should be 8 ohm minimum. Of course, I did not now this until I purchased everything and had all the components delivered. I would hate to sell the speakers, but I am worried I will damage the receiver. If you hook up the speakers directly the.
How do you hook up your computer speakers to your computer? They should plug in on the back. The socket is often green for the main speakers. If that doesn’t work, try a socket on the front. If there are no sockets, then you would need to install a sound card. If you get no sound, then check your connections, make sure your amplifier is getting power …unless you are using lightweight headphones and have them plugged directly into the computer , and check your sound drivers.
If you just installed your OS, then you may need to go to the sound hardware manufacturer’s site or the motherboard manufacturer’s site and download the drivers. Or you might have a driver CD you need to install. You should also make sure you didn’t disable the sound hardware in the control panel or in the Windows volume control options.
Will my old speakers work with a new receiver
It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit? The amp comes with FX loop but currently my new setup is running everything upfront. I only want to gate my drive pedals and vibe.
Troy, Those subs are dual voice coil (DVC) 2-ohm subs and they can only get wired together to form a one-half ohm load, a 2-ohm load, or an 8-ohm load, so using that amplifier bridged won’t work – it’s not stable bridged into one-half or 2 ohms and won’t put out much power at 8 ohms.
Tweet When it comes to volume, a speaker’s rated wattage is only part of the equation There seems to be some confusion when it comes to how “loud” an amplifier can get. When it comes to “volume,” many musicians only consider the amplifier’s power or wattage rating, and in general, more watts does mean “louder. Decibels and levels Decibels abbreviated “dB” are a logarithmic unit of measurement that pertain to a ratio between two numbers.
Okay, I can see eyes rolling and glazing over, so I’ll simplify things, and attempt to keep the “math” to an absolute minimum. With a logarithmic scale, you can’t just add numbers in the usual way—a doubled number isn’t “twice as much,” but rather, many times more. For example, dB is many times greater than 50dB, not just “twice as much. In other words, if one amp is generating 90dB SPL and another amp is hitting dB SPL, the second amp will generally be perceived to sound about twice as “loud” to the typical listener.
Wattage, power, and SPL So how many watts does it take to get twice as loud? Let’s imagine two amps—one amp rated at 10 watts, and a second amplifier rated at 20 watts. The watt amp is double the power of the watt amp, but doubling the power only translates to an increase of 3dB SPL.
