New Insights into the Dangers of Using Power Amplifiers That Are Too Small

When you're matching a good speaker with a good amp, it's all about synergy. Not that it's always simple to achieve - this is a little more complicated than making a sandwich! If putting them together is giving you a headache, we can help. This is our full guide to matching speakers and amps, and it's got everything you need to know. You don't need to be Einstein to get this right, but before buying a thing, you do need a vocabulary lesson.

These are the key terms used in speaker and amp specs that are critical to your search for good synergy and great sound. First up, Impedance. Impedance starts with I, just like important. Used in both amp and speaker spec sheets, impedance is a measure of the electrical resistance of your components. This is part of the equation in determining the synergy between your speakers and amp.

Speakers typically carry ratings between 4 and 8 ohms. Amplifiers generally operate effectively in a specified range: say, 4 to 16 ohms. Check your specs, but when that's the case, connecting a speaker rated between 4 and 16 ohms will be OK. But—and this is where it gets more interesting—you need to be aware that many amps output different wattages into different ohms.

We'll go into wattage in more detail below—for now, all you need to know is that it's a measure of power. Generally speaking, it's fine to connect higher impedance speakers to an amp; what you don't want to do is plug low impedance speakers, let's say 4 ohms, into an amp that specifies a minimum 8-ohm limit.

To take some math work and guessing out of the equation, a lot of speaker and amp manufacturers are switching over to using "compatible with" ohm ratings, which makes things a lot easier. Power can be confusing. One common belief we'd like to shoot down right now is that more watts which is what you use to measure power equal more volume. Watts are more about how much power a speaker can handle and how much power an amp is putting out. For simplicity's sake, we're going to talk about Continuous Power and Dynamic Power in this guide.

Continuous Power is where the magic's at. This is the spec that tells us how powerful an amplifier is. A typical spec sheet might read something like "50 watts Continuous Power into 8 ohms," meaning the amp will output 50 watts into an 8-ohm speaker. Dynamic Power is essentially a measure of an amp's maximum power output when pushed beyond its Continuous Power rating—we're talking peaks of power for milliseconds during a dynamic song or soundtrack here.

As for speakers, every manufacturer seems to rate power a little bit differently. Many high-end speaker manufacturers are swaying away from offering Continuous Power and Peak Power ratings, favoring "recommended amplification" ratings instead. Don't ask us, we just work here. A speaker-specific stat, sensitivity is essentially a measure of how loud a speaker will be in decibels from one meter away when driven by one watt of power yes, just one watt.

Here's an example. We've already mentioned the KEF LS50, so let's take a second set of speakers - the Audioengine HDP6 full review here , which we just happen to have lying around our testing room. With one watt of power, the HDP6s will produce a sound pressure level SPL of 88dB at a one meter distance—just about perfect for not going deaf during long listening sessions.

The human voice is about 60dB during normal conversation. Why does sensitivity matter? It directly relates to how loud a speaker gets. When distance and power are the same, a lower sensitivity speaker say, 85dB would sound quieter than a higher sensitivity speaker say, 88dB in the same room and setup.

Sensitivity doesn't make or break a good speaker, but a higher-sensitivity speaker could save you from having to buy a larger amplifier to reach your favorite listening levels but we'll get to that later. Here's another fun fact about sensitivity: Amplifier power must double to increase a speaker's SPL by 3dB.

So, our HDP6s would need one watt to produce 88dB of sound, two watts to produce 91dB, four watts to produce 94dB, and so on. Conversely, sound falls off fast. Expect a 6dB falloff every time you double your distance from your speakers. And this is why we can't just pick an amp and speakers with a couple of matching specs and hope for the best. This amount of power is safely within the 25 to watt recommended amplification range of the 8-ohm LS And since the LS50 carries a sensitivity rating of 85dB, we know it will play plenty loud in a small room.

So: our amp and speakers match impedance at 8 ohms; the amp's Continuous Power and Dynamic Power are both safely within the speaker's power handling range; and the speaker's sensitivity will allow it to reach good volume levels in a small room. Sounds like we have some synergy here. Do you want to know what the most common email we get it?

There are thousands and thousands of different products out there. Modern equipment is very forgiving and most of it is very well built. Finding that sound is kind of up to you! OK — there are some ways in which you can streamline this process. Buying an amplifier and speakers from the same company is usually a good start, as the hard work of making them play nice together has been done for you. But do you want to know what will make a much bigger difference?

Your listening environment. Too often people don't account for the impact their room will have on their setup, and we don't want you to do that. So, let's put these factors into practice. A large room could require larger speakers or more powerful amps than you anticipated getting. Where the speakers will be located, as well as where you'll be seated, are big considerations.

Keep in mind that you'll sacrifice sound quality if your speakers and listening position aren't planned correctly. We generally recommend spacing speakers one-and-a-half times as far away from you as from each other, angled slightly inward, at the same height, and with the tweeters as even with your ears as possible. And always avoid obstructing your speakers with furniture and placing them in corners or too close to walls unless the speaker manufacturer advises otherwise.

You should figure out how far you plan to sit from your speakers. Second, get an idea for how loud you want them to sound. These two figures are essential in determining the speaker sensitivity and amp power ranges you need to work within. If you happen to already have a speaker in mind, Crown Audio has a really handy calculator that you can plug distance, desired SPL, and speaker sensitivity figures into to calculate just how much Continuous Power you need out of an amp.

Then all you need to check on is if that power rating is within your speaker's safe operating range. Obviously, speaker sensitivity plays a bigger role than a lot of people think it might, and you can use this calculator to see how big of an impact it makes. Point being, if you need watts of power to get your 85dB speakers singing at the volume you want from your listening chair that's three meters away from your speakers, but your speakers are only rated to handle watts of Continuous Power, well, you're outta luck and you've got no synergy.

Start looking for a different speaker—or sit a whole lot closer to it. Ask a dozen audio experts about how much amplification a speaker needs given its power handling rating and you'll get a dozen different opinions. We've seen recommendations for ten percent more Continuous Power over a speaker's comparable power handling capabilities.

We've also seen recommendations for doubling a speaker's Continuous Power rating. These recommendations likely spawn out of the belief that too little power is what damages speakers rather than too much. It actually goes both ways. There are two very common and unfortunate causes of blown speakers and amps that we want you to avoid at all costs.

First is connecting speakers to an amp with a Continuous Power rating that's way too much for your speakers to handle. What often happens here is that the speaker can't efficiently dissipate the heat energy from the amp, which then burns up the speaker's voice coil and suspension, meaning you may as well have lit your hard-earned money on fire instead. Second is running an amp that is far too weak for the speakers connected to it. It's not that the lower power is bad, but it gets bad when you keep cranking up the volume knob in search of a suitable listening level that likely doesn't exist; instead your amp will start burning itself up because you're demanding more power than it can create.

This causes the amp to overheat and start clipping the signal being sent to the speakers, creating excessive distortion and high frequency energy that can, and likely will, waste your speakers away. Then you'll have a burnt-up amp and speakers. So, let's not do that. Our recommendation for the ultimate safeguard against smoking your system is to carefully look at the maximum power handling capabilities of your speakers and amp, and, based on the listening room specs we talked about, choose an amp that outputs the correct Continuous Power for the volume level you seek , and a speaker that can gobble up twice that amount of power.

So, if you need watts out of your amp at 8 ohms, pump it into an 8-ohm speaker that can handle watts of Continuous Power. This should give you plenty of headroom for when the impedance drops, causing those Dynamic Power peaks, and a little more room to spread those gooey peanut butter vibes.

How Much Amplifier Power Do I Need?

The time is here to start off with a fresh new year, with new hopes and aspirations. Most importantly, this is the season of hot deals and discounts and attractive price tags. Indeed a great time for going about audio equipment upgrades or maiden purchases. With audio equipment sales, the advertisements look uber cool, flashing a long chain of zeroes on the power output numeric. Such a huge wattage figure is good enough to trick one into buying poor audio gear. It would be great to understand why such 4 or 5 digit wattage figures are unrealistic and make no sense in the real world. Amplifiers and loudspeakers have their own limitations with respect to the amount of electrical energy that they can amplify and convert to sound energy without any audio signal distortion or damage.

Speaker RMS higher than Amp RMS

Well, when it comes to matching that amplifier with your speakers, the answer is; quite a bit, actually. Though we spend countless hours scouring local HiFi suppliers and reading reviews to find the perfect speakers, often, our choice of amplifier is something of an afterthought. This remains true despite the fact that amplifiers are almost as crucial to the tone and overall presentation of your audio as your speakers are. Yes, though that innocuous metal box might look similar to other amplifiers in the showroom, it will produce a unique sound profile and, through its technical specifications, support some — but not all — of the speakers available to you. As such, this guide is going to be something of an essentials piece, giving you all the information you need without the complicated maths or advanced terminology like slew rate, dampening or electromotive force, so you can get back to what matters — your music. So, for your devoted audiophiles, let that serve as a warning! Key to ensuring effective synergy between your speakers and your amplifier is having a basic grasp of HiFi vocabulary.

How do you match speaker RMS to amp RMS?

Home English In-Depth Speaker power handling. Speaker power handling. Number of Views: One of the many confusing issues in professional audio is that of loudspeaker power handling. On one side, manufacturers use a variety of terms such as peak, RMS, average or program power.

PA Power Ratings

Home - Speakers - Power Ratings. Updated: November 23, A typical specification for home theater speakers is the speaker power rating. But, what does it mean? And, how do you match the speaker power to your amp? The speaker power rating should be an essential consideration for anyone who is looking to buy new speakers.

Ohm 4000 speakers

Your local drive-in DJ, the next-door neighbour or even your best friend bragging about their new sound system might sound familiar to you. Sure, a 1, Watt speaker is louder than a Watt model but definitely not times as loud. As a matter of fact, sometimes a 1, Watt speaker can produce more volume than a 1, Watt one. This blog is written to separate the facts from fiction and show you how it really works when it comes to the power capacity of speakers and amplifiers. An amplifier outputs power and passes it on to a speaker. In turn, the speaker takes the power and processes it.

The factory stereo installed in my car is not powerful enough to cancel the road noise. So, I decided to upgrade it, and the first question that came into my mind is, how many watts is good for a car stereo? In general, for a good audio experience, the car stereo should have more than 20 Watts RMS per channel. This wattage level is enough to power most standard car speakers and provide a satisfying sound experience. Many factory-installed car stereos produce 5 — 15 Watt RMS per channel, and because of that, they do not provide an impressive on-road stereo experience.

We are proud to present the renovated SR 5. The Audison design team, headquartered in the Potenza Picena Italy , spent a long time planning and perfecting the new SR line, taking full advantage of the features that the most recent amplification devices available today are equipped with. As for the electronics design, the Audison style center has taken care of every aesthetic and functional detail, obtaining a compact amplifier made of extruded aluminium with rounded corners that ease the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often cause of noise and dust accumulation. As per tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any type of audio system configuration. The controls, protected by a satin-finish aluminium panel, are located on the amplifier upper panel, to be easily reached from above even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.
