Bonus: Onkyo TX-NR616

Other Options

AV receivers that officially supports 4 ohm impedance are not as popular as those supporting higher impedance speakers.
 
As such, we have included a bonus list of other receivers supporting 4 ohm amps.
 
However, these are older amps. These receivers are normally rated at 4 ohms or higher and include the popular Onkyo TX-NR616 and Yamaha RX-V773.
 
Keep in mind however that some older receivers may not offer more modern lossless audio formats, like DTS HD and Dolby Digital HD.

Popular Receiver Brands For 4 Ohm Speakers

In terms of receiver brands that support 4 ohm receivers, Denon, Onkyo (mostly older models), and are usually Yamaha usually safe bets.

Impedance Matching Your Reciever and Speakers

As we have said, when a speaker’s impedance (ohms) is low, electric signals freely flow through your them, making 4-ohms speakers more power-hungry than higher impedance speakers like 6 ohms and 8 ohms speakers.

Impedance Matching Your Reciever and Speakers

This is why you will find more 8-ohms speakers than 4-ohm speakers readily available on the market. So, before making your buying decision, it is essential to consider that many receivers and amps are not designed to handle 4-ohm speakers.

Does this difference matter? Yes, if your speakers require more power, but your receiver cannot deliver, the speakers are highly likely to blow the receiver. If you want to get the best experience, you should match the impendence of the speakers and receiver. When it comes to 8 ohm vs 4 ohm and which is better, power is the most important consideration.

When we are talking about impedance matching, we are referring to the process of designing an electrical load’s input and output impedance to maximize the power transfer and minimize signal reflection. To put it simply, it’s just the process of making one impedance look like another.

Since 4-ohm speakers require a high amount of power, you can solve the problem by buying AV receivers that supply the power levels required.

let’s say you have a 5.1 surround receiver. This device will have to deliver a tremendous amount of power to be capable of powering five 4 ohm speakers along with a sub. This means the load per channel which they can deliver is typically more limited and you risk blowing a receiver channel or blowing the entire device if you’re not careful

However, manufactures have already handled the technical work on your behalf, so all you need to do is select a 4 ohm certified receiver. Most receivers on the marketplace have an impedance between 6 ohms to 16 ohms, and they can serve your needs perfectly well.

Using a certified 4 ohm receiver is the best way to ensure you have a fair workload that the receiver can drive safely without the risk of overheating or damage in the process. In any case, we do recommend the addition of an external amp to ensure you are driving these low impedance speakers with substantial power. 

There are also many technical formulas that you can use to calculate and match impedance. Many experts use the Smith Chart Impedance matching, mostly used for RF applications. However, you can match impedance without going technical.

Do I Need An Amplifier For My 4 Ohm Speakers?

As we have said, due to the power demands of low efficiency 4 ohm speakers, we do recommend that you include an amplifier when connecting 4 ohm speakers. If not, you risk overheating and damaging your receiver. 
 
In this case, it’s a good idea to get a low impedance amplifier because it will allow you to power low and high impedance speakers.
 

How to Prevent Overheating Your Receiver and Amp

If you are driving your amp with too many low impedance speakers, the amp and receiver will likely heat up.

To make it worse, if you cram the devices between air-tight TV furniture and other badly ventilated spaces, you risk choking the amp and overheating the receiver.  

 

Should I Use 4 Ohm Speakers with My Receiver?

To answer this question, it is important we step back and consider the important thing that your receiver provides, and your 4-ohm speakers need, and that is power. If your receiver can deliver the right amount of power, you can use the speaker with it.

4 Ohm Speakers with Receiver

Remember, most modern receivers have impedance settings that you can use to match the speakers’ and receiver impedance. For example, if the receiver’s default impedance is 8 ohms, you can use the settings and reduce it to 4 ohms.

Even though this setting can be helpful, we do not recommend that you use a 4-ohms speaker with any higher-impedance speaker. Setting the receiver impedance to 4 ohms lowers its maximum power output.

In other words, by opting for the lower impedance setting, you are telling the receiver to reduce its overall performance.   

So, you should only use 4-ohm speakers with your AV receivers that support them. Your AV receivers should be 4-ohms certified. Remember that there is no harm in using a lower impedance receiver with a higher impedance speaker.

So, if you have receivers rated 4-ohms and below, it is safe to use them with 4-ohms speakers. The only challenge is that the receivers are difficult to get in the market.

Can I Use Any Receiver With 4 ohm Speakers?

No, you cannot use any receiver with 4 ohm speakers. For example, if your Denon receiver turn off and blinks red with a 4 ohm speaker, that means it is in protect mode due to the low impedance. 

So, we have seen why you should not use 4-ohms speakers with higher impedance AV receivers. You may be asking whether there are exceptions to this general rule.

Yes, there are a few exceptions party from receivers that clearly allow 4 ohm speakers. You can use some other receiver with 4-ohm speakers in rare cases.

Can I Use Any Receiver With 4 ohm Speakers

Firstly, remember that the indicated impedance is a nominal figure. It is a sort of average. So, if your speaker’s impedance can rise to about 8 ohms and the receivers’ impedance can be around the same figure for a significant portion of their curves, you can use the receiver with the speaker.

On the other hand, some speakers can fluctuate significantly and drop low on their impedance curve (such as Magnepan speakers, for instance).

However, this not always the case, especially if the receiver has an extremely high impedance rating. For example, if the receiver is rated 16 ohms, you should not use it with a 4-ohm speaker.

If the impedance fails to fluctuate you desire, you can opt to use the impedance settings. As we have said, this is an important solution, but it will reduce your receiver’s overall efficiency. However, if the quality reduction is not your major concern, you can use the settings to match the impedance.

Another common solution is reducing the volume of your audio/video system. You may know that if you use a 4 ohm speaker with any receiver with higher impedance, the receiver will likely blow if you turn the volume too high. 

However, the receiver will not have to supply too much current if you keep the volume extremely low. As you likely know, the higher the volume, the higher the amount of power that your speaker demands.

So, in some cases, you can use any receiver with 4-ohm speakers, provided you ensure the speakers are getting adequate power by keeping the volume as low as possible.

Can I Use 4 Ohm Speakers With My Receiver?

Can i use 4 ohm speakers with my receiver? Yes, you can use 4 ohm speakers with 4 ohm rated receivers.

You can use a 4 ohm rated speaker with receivers rated 6 to 16 ohm as well but you need to be careful that your speakers aren’t pulling too much power from your receiver. You need to keep the speaker volume low and ensure that the power is matched.

If you are not careful in keeping the volume low, you run the risk of overdriving or clipping the receiver or amplifier if one is attached. 

How Many Watts Can A 4-ohm Speaker Handle?

Different 4 ohm speakers will be able to handle different levels of power depending on the manufacture. This could be for example 30 watts all the way up to 400 watts, more or less.

In any case, you need to check the specifications of the speaker you are using. Importantly, you need to consider the amp. 

Let’s say we have an amplifier with specifications of output power is 100 watts RMS at 8 ohms.

This means that the maximum output power of a 4-ohm speaker is 200 watts. However, you need an amplifier that can double the power specification of the speaker and so you need an amplifier that can produce at least 400 watts for this 4 ohm speaker.

Are 4-ohm Speakers Better Than 8ohm?

A 4 ohm speaker will be able to accept greater power than a 8 ohm speaker. In fact, all other things remaining equal, a 4 ohm speaker will be able to handle twice the power of a 8 ohm speaker

However, this does mean that you need a more powerful amplifier for a 4 ohm speaker than a 8 ohm speaker; with all other factors remaining equal.

Can 4 Ohm Speakers Be Used With AV Receivers Instead Of Power Amps?

You can use a 4 ohm speaker directly with a receiver if the receiver is rated at 4 ohms, the wattage is matched and you do not max out the volume. The best option is to include an amplifier in the setup if your speaker require considerable power. On the other hand, if you have a powered speaker, you can connect it directly to your AV receiver.

What Is The Cheapest Av Receiver That Can Be Used With 4 Ohm Speakers?

It is difficult to find good and cheap AV receivers that support 4 ohm speakers. This is because these speaker normally require a lot or power and are not easy to drive. It is best to have a power amplifier if you do not have a lot of money to spend. 

If you are set on using a receiver that is rated at 4 ohms then here are some affordable options:

  • NAD T 748V2
  • Marantz US SR5009
  • Marantz US NR1608
  • Onkyo TX-NR656 7.2 Channel Network A/V Receiver

Final Verdict

There you have it, the best AV receivers that officially support 4 ohm speakers. As you may have realized, receivers that support 4 ohm speakers are not cheap equipment to begin with, quite frankly.

However, you should be able to use these receivers with your low impedance speakers and get excellent results. Remember, you may not get the best listening experience if you ignore impedance matching.

Finally, keep in mind that even if you are using a receiver that can support your 4 ohm amps, it’s still a good idea to use a power amp if you will be driving your speakers at max power for extended periods of time.
