How To Match Speakers With Amps? Ultimate Guide 2022

A company that runs events needs to make sure that they choose their speakers carefully. The speaker is the face of the company. You need to ensure that the speaker is an expert in their field. Also, they need to be able to present their ideas clearly and in an engaging manner. This is why you need a platform like am to help you find the right speaker for your event and also help you match your speaker to your audience.

Speakers and amps take their relationship cues from PB&J against all odds. With their gooey-fresh goodness, they should be the envy of nature. But how do you mix the right recipe together that works? There’s a lot to consider. And it can be tough developing those qualities in your product. That’s why we conceived The Ultimate Guide to Speaker Placement and Amplifier Matching for DJs which contains everything you could possibly need to know about mixing your technological ingredients through a process that will bring out the best in both partners whether you are an experienced DJ or professional working towards achieving perfection!

1: The best way how to match Speakers with amp for listening to music

Amplifiers come in many different shapes and sizes, but all of them are designed to multiply, or amplify, a relatively small electrical signal (e.g. from your car radio) into a current that will drive your loudspeakers (e.g. car speakers). You’re probably wondering what differs between an amplifier and the average speaker out there. Essentially an amplifier takes a weak audio signal and powers it up to make it audible through speakers which in turn produce the sound you can hear. An amp is therefore an essential component of any car stereo system because without power there is no output or audio. So basically amplifiers are the brains behind your loudspeaker setup.

There are different steps to do below:

Step# -1

When you select speakers for a specific application, make sure their power handling is suitable to that application’s wattage needs. Find an RMS (Root Mean Square) wattage rating as it represents the continuous power handling limit of a speaker over long time periods.

Step# -2

Check the output of your amplifier by finding it in the owner’s manual. Look for “RMS” (root mean square) which stands for continuous rating and represents the amount of power that the amplifier can continually dissipate without overheating. For example, if you have a 150-watt RMS amp and a speaker that can handle 100 watts RMS, they can be compatible but they attach to each other best at around 86%. This is because if we’re not careful, it may overwork your amplifier and burn out the speaker or something else which then affects how your brand sounds! It’s a good idea to stay around 15% between them including their minimums. So what does this mean? I should just understand that I should be very careful about which speakers I buy for my amplifier?

Step# -3

Don’t forget about the quality of your audio when it comes to purchasing a car stereo, as this is important for enjoying both music and radio broadcasts. When buying a four-channel stereo, don’t make the mistake of assuming you only need to purchase a three-channel amplifier that will cater to three speakers and the subwoofer. Without hearing the difference in sound quality yourself, you might not understand how important or easy it is to hear those whistles and other low-frequency sounds with a four-channel amp over a three-channel amp.

Step# -4

Check to make sure that the input/output frequency match-up works properly. For example, front full-range speakers need an amp rated high enough to output a full spectrum of sound… or else it might not be able to reproduce mid-range sounds as well as low-to-high ones. Likewise, all surround sound speakers basically work off a bass-reflex formula, thus subwoofers will usually do better when paired with another subwoofer amplifier rated similarly.

Impedance Explained:

When shopping for speakers and amp sets you need to factor in a few things. You need to bear in mind what components the set will be working with (computer, TV, other sets) and how many watts are needed. What’s more important is – when buying a combination of a wireless speaker and amp as part of an all-in-one package, make sure you’re getting one that complements each other. Additionally, be sure not to miss the audio spec sheet. It contains important information on how everything fits together from power requirements to cables and yes, even plug types!

First up: Impedance. It’s important to understand that impedance is important when you’re building a system. When it comes to compatibility, this particular spec is often represented in amps and speakers via its numerical equivalent which is measured in ohms usually accompanied by the symbol “Ω”—as in 8Ω for example. As an amplifier, if you’re operating within a specified range of x ohms then that works well with your respective speaker impedance rating as it helps to maximize efficiency. If you want to know for sure exactly how compatible your amp and speakers are going smooth sailing without any issues or feedback then we suggest checking out your speaker specifications where you will be able to get a clearer picture of how compatible they really are as some cases can often be deceiving! If at any point during setting up your system you have questions or concerns then please don’t hesitate to contact us!

But as you’ll discover, that output isn’t fixed. For example, the power output tube in certain amps may not always reach its potential output. This variation is typically due to voltage tolerance and changes to the internal resistance of the amp. Therefore, at times you may see different wattage ratings on an amp’s specs sheet based on different impedance ratings. For example, NAD’s ridiculously popular D3045 stereo integrated amplifier has a 60W per channel continuous rating at 8 or 4 ohms; yet peak power adds another 5 watts over both values for a 75W per channel max at each impedance level.

Generally, it works to hook up high-impedance and low-impedance speakers to a receiver provided that you are using an amp with a high enough wattage rating to utilize the latter. However, it’s important not to hook up a 4-ohm speaker to an amp that specifies a minimum rating of 8 ohms. To take some guesswork out of the process, many amplifiers are going with “compliant” or “compatible with” ratings that should clear things up.

2: Power Explained

Power can be confusing. We want to start by shooting down one common misconception to avoid as a rule at the onset, and that is just because your speakers or amplifier have a certain wattage rating does not mean that you will get an equal amount of volume out of them. Oftentimes the wattage refers more specifically to how much energy can be produced with each channel. The continuous power output spec is often what we find most relevant when experiencing audio quality in our everyday home life since it tells us specifically how much energy can be produced without having an uncontrollable distortion of sound over time due to thermal build-up if the speaker itself consumes too much power, potentially causing it to fail prematurely (or even worse, explode!).

The one thing that’s at the heart of our Pulse Amplifier is its Continuous Power, or wattage output when working within FCC limits. Speaking of watts, what does that number actually mean? Well, this measurement determines how powerful an amplifier is — most importantly for your home theatre setup. When it comes to high-power amplifiers, you will want your amp to have some ability to pass the full rated power on to subwoofers while maintaining cleaner sounds with your mid and hi-fi speakers. In other words, you’ll want a stereo receiver that can deliver upwards of 300-500 watts RMS through loudspeakers and as much as 1000 watts RMS into your subwoofers.

2: Sensitivity Explained

Most loudspeakers are frequency sensitive and the fact is, most of them have poor bass reproduction. For example, smaller drivers tend to suffer from this phenomenon. As a result, KEF’s LS50 (full review here) is going to make you feel like you actually live in your favorite action film or any other great piece of music for that matter. However, Audio engine’s HDP6 (full review), in its own league outperforms even the finest speaker ever made but we’re not giving it the highest score of all time because it still doesn’t get good scores when it comes to sensitivity.

When selecting a new music system for your home, it’s important to know that the speaker’s sensitivity rating (explained below) is an indication of how loud your system will get with a given amount of power. For example, a lower-sensitivity speaker may only get about 10 decibels louder when you double the number of watts fed through to it, whereas a higher-sensitivity speaker may get 20 decibels louder than its lower-sensitivity counterpart — meaning you will need 20% less amplifier power to reach the same volume levels (but we’ll talk more about amplifiers later as well).

Have you ever wondered why you can’t just add more power to your speakers and expect a louder sound? In order to get a certain number, say 94 decibels, one could theoretically add an amplifier that would produce 4 watts. But the bad luck, what goes up must come down. Every time we double the power of our amplifier, we lose 3 decibels of sound pressure level. That 6-watt amplifier sounded great right! Well unfortunately it only makes 88 decibels – that’s loud but not nearly as loud as it was before. This is why it’s important to choose the right sensitivity rating when choosing your equipment! The rule of thumb is that at each doubling of distance from a speaker (5 feet instead of 2 feet) you will lose about 6dB in volume or half the volume.

3: A Practical Example

Take the KEF LS50 speakers, for example, which output 0.97V at 1m but are rated for two drivers in total (the D3045 has an internal Bridging Slow Blow fuse as well). Now while there are 2×8Ω bridged together in the KEF LS50 and that adds up to a 4Ω rating (which doesn’t exactly match the NAD’s 2×4Ω or the KEF’s recommended requirement of 4-8 Ohms), we can safely assume that this will drive the KEF LS50 easily in a small listening room – even though the NAD D3045 is underpowered in comparison to what’s recommended by KEF. After all, given its low output impedance (.2Ω) and reasonable power output (40Wpc into 8ohms and 23Wpc into 4ohms), we know that this pairing should still sound fantastic despite their impedance mismatch and high sensitivity.

So, we’ve discovered that our speakers can handle a considerable amount of power without damaging them as long as the source we use is similar it also happens to be able to get loud in a tiny-sized room.

How To Match Speakers With Amps?

How do you choose an amp? One word: experience. There are way too many options these days and it can be really tempting to pour over all the details and spend hours comparing specs, but there’s only one way that you can really get a feel for what works best for you and your speakers – trial and error. You don’t need to read reviews or manuals to know this, just out of curiosity, try pairing your speaker with another pair of speakers and see how it goes. Not sure where to start? Perhaps pick something that catches your eye in ads or has rave reviews from users; our trusty tech support guru Morris tends not to refer clients to certain amps because he thinks they might not be the ‘perfect match. He’s always been right about recommendations so far.

You really don’t need to know the engineering side. As long as you’ve got a good set of speakers, an equally good amplifier, and they both match in power, it’s all good – they just work! Most modern equipment is built so well that even though two pieces of equipment may not necessarily interoperate with each other, they also don’t cause issues by working together either. Trust us: you don’t need to get involved in technical mumbo-jumbo when it comes to building your own system. It’s more about finding something you like the sound of rather than worrying about technical matching. Finding music that you enjoy is important!

There are some types in which you may streamline this process. You see, buying an amplifier and speakers from a single company is usually a good start because they’re compatible and therefore unlikely to create any issues.

These are the factors that will make a big difference: listening environment. People don’t take into account how the room will affect their setup, so we want to make sure you know what’s best to do with the room, which is letting it be treated properly.

If you have a large room, it may require larger speakers or more powerful amps than anticipated. In addition to this, where you seat yourself when listening to music and where the speakers will be placed are all considerations. Also bear in mind that while you might sacrifice some sound quality if you don’t put your speakers as equidistant from each other facing towards you with tweeters on top of your ears as possible, there are many factors that contribute to building the best listening experience for yourself.

When buying speakers, make sure you determine the optimal distance from your speakers to your ears. Once that is determined, make sure you have an idea of how loud you want them to sound. Now calculate speaker sensitivity and continuous power figures for your amp based on the distance, desired SPL level, and speaker sensitivity. If you already have a speaker in mind, try Crown Audio’s handy calculator to see what kind of output power your amplifier needs to put out in order to create that desired volume without going over the recommended continuous safe operating range for the speakers. Just one more step would be making sure this kind of continuous power output rating falls within the maximum input amplifier continuous output specifications – but if our maths was correct in determining what amp power is needed, this should not be a problem.

Obviously, speaker sensitivity plays a bigger role than most people know, and it’s crucial to accurately measure your speakers’ sensitivity (as per 1W@1M). The only problem is that the decibels you get from any speaker are based on the driver specifications, usually listed in terms of Continuous Power. So if you need 200 watts of power at 85dB from your system placed three meters from the speakers being listened to, but your speakers can only handle 100 watts of continuous power, you’re going to be stuck because there’s no real synergy between drivers/speakers with lower sensitivity and an amp with higher output. Start looking for a different pair of speakers or sit closer.

Safety First:

It goes without saying that we’re not professionals when it comes to audio. However, as a general rule of thumb, we’ve found that with high-powered professional/commercial audio systems (starting around 300 watts per channel) you may be able to play loud or give the illusion of being loud even if your speakers aren’t being fed enough power. Conversely, if you can hear the music clearly at normal listening volumes and your equipment isn’t producing distorted sound then it’s unlikely you are overloading the amplifiers and thus damaging them. In the end, it just takes experience to determine what really counts as an overload. If you thought your broken speakers were caused by an amp’s maximum output capabilities but in actuality, they weren’t being fed enough amplifier power then you might have blown up your speakers for no reason causing additional headaches for yourself.

Conclusion:

When there is discussions about music, everbody has their own preferences. Some people love listening to hard rock and metal and some prefer to listen to classic songs that were written decades ago. Whatever it is that you like to listen to, it’s important to have speakers that compliment your music. If you’re looking to buy some new speakers, it’s important to know what to look for and what to avoid. In this blog, we’ll talk about a few tips that will help you find the best speakers for your music.
