Lower powered speakers

Speaker sensitivity is a measure of how efficiently a speaker converts amplifier power to acoustic energy. In other words, it tells us how loud the volume will be for power output from the amplifier. With a speaker, we are talking about the acoustic output, or the volume, resulting from a given amount of power. Measuring the decibel dB output of a speaker when applying 1 watt of power provides the degree of sensitivity. The measurement is taken at 1 meter from the speaker and is usually performed in an anechoic chamber non-reflective, soundproof room.

THE INTERRELATIONSHIP OF SPEAKERS AND AMPLIFIERS

David, aka Grumpy, needs our help. Great news. David is home! It was quite the ordeal to get him home and into the house, but it is done. Thank you to everyone for their support. Now a long road ahead to get him back on his feet and functioning normally. I have started a GoFundMe to help with the medical bills. Please help, if you can. Discussion in ' General Audio Discussion ' started by ginetto61 , Oct 22, Log in or Sign up. Messages: Location: Italy. Often i read about great speakers with good sound but difficult to drive properly and that need very powerful amps.

I am wondering if selecting a high efficiency speaker could be a more recommendable option. So that good sounding but low power amps could be used without problems. Speakers like Tannoys or Klipsch i mean Suggestions will be welcomed and appreciated. Messages: Location: Virginia.

Generally speaking, yes. I've got a low power vintage Pioneer receiver, the SX, that drives a pair of Klipsch bookshelf speakers quite well. I've also got another low power Cambridge Audio amp that drives a pair of Paradigm bookshelf also admirably. Speaker efficiency seems to have a lot to do with it.

Anyhow one should also keep an eye on the speakers impedance as well just to be better informed. But that said take any speaker specs with a grain of salt,as they can lead one astray. Often having some experience with a given speaker will be more reliable than the printed specs. That's why having a place like this can be such a great resource for any audio fan.

All things considered, it is better to have more watts and not need them than not have them, then need them.

Why be restricted to the kind of speakers one has to use? Bodyblue , Oct 22, Messages: 11, E-Stat , Oct 22, Messages: 35, Location: Lindenhurst, IL. Messages: 3, Location: Ocala Florida.

However, my Compression Drivers, JBL, are db efficient to I can be driven out of the room with less than one watt.

Given that, I would first look for the sound you like then build your system to match. If you like big electrostats, you'll need plus per channel from the amp.

The problem they run into is the laws of logrithmic declines at their limits. But, those last few watts around it's limit it starts to huff and puff and gets distorted. It is perfect for a bedroom where its never called upon to give more than watts. I am in the camp above.. It's better to have too much and not need it than not enough, mostly for a main system where it takes an extra 80 watts to go from 80db to 90db.

Think of a basic stock hp corvette that does mph off the showroom floor, but needs hp to go And yes, Infinities are never easy to drive.

Just have a good amp and they are fine though. Bodyblue likes this. Messages: 2, Location: SoCal. I think it CAN be a sensible choice. Some seem to have the goal of getting by with the least power, and will find speakers that work with that. Others buy hundreds of watts of power, and often never take advantage of it. Another group buys speakers they like and then drive them with a suitable amp. Some have a favorite amp or receiver that they like and find speakers that sound good with it.

All are fine, and none is more valid than another. Personally, I like a little leeway in my setups. By that I mean that I'd not want a super low powered amp that works great with X speaker model but is way underpowered when I want to give Y speakers a try.

I'd say to decide on the speakers and go from there as a good starting point. FWIW, my main speakers are not particularly efficient, are 4 ohms, and really like lots of power. They sound good, though, and I don't think that they'd sound better if they were more efficient. Currently, I have them connected to an amp that's rated at WPC at 4 ohms, and they sound really good.

They didn't sound quite as open with less power, and the sound at higher levels seems much more effortless, if that makes sense. This is in no way a real test, but it's enough for me to decide to use the bigger amp with these speakers. As a plus, any of my other speakers sound great on it, too.

How Many Watts Is A Good Speaker?

One of the most confusing topics in home-audio design is figuring out what size amplifier your speakers need. Usually, people make such a decision based on simplistic and sometimes meaningless speaker and amplifier output specifications. Many tend to follow misconceptions about how amps and speakers work. Speaker power handling specifications are usually meaningless.

Do Powered Speakers Need an Amplifier?

The spec will look something like W; W rms , or W peak. What is speaker power handling wattage rating? The speaker power handling specification aka wattage rating is the measured or theoretical limit of electric power the speaker is capable of handling before burning out. To understand the power handling ratings of speakers, we should understand what power is in the first place. Electric power is defined as the rate per unit time at which an electric circuit transfers electrical energy. It is measured in the SI unit of watts W. The power amplifier in our signal chain provides amplified audio signals that can properly drive our speaker s to produce sound. The transfer strength of these audio signals is typically rated as an amount of electric power in watts. Basically, speakers are transducers that convert electrical energy audio signals into mechanical energy sound waves.

Speaker Power and Distance

More attention needs to be paid to the sensitivity rating of a speaker, which we call out as the SPL rating on our speaker specifications. This SPL rating is listed with a given input at a fixed distance. The SPL rating is highlighted in yellow above. This speaker has an average output of 95 dB when measured at 1, 1. Power handling, highlighted in green above, is listed at 4 watts continuous and 5 watts maximum.

To some people, looking for the matching amp for their stereo speaker system and trying to achieve the best possible synergy, is an adventure. They love doing it, they love trying different combinations, and they enjoy every moment of that journey. After reading our short guide, you will know exactly what to look for. The first step to getting a better understanding of the process of finding the right amp for your speakers is understanding the specifications. To keep things simple, our focus will be centered on the three most important specs — power rating, impedance, and sensitivity.

Speaker Wattage & Room Size – How Many Watts Per Square Foot

Active loudspeakers have built-in amplifiers and require a power source. Loudspeakers are available in two formats: active and passive. Smart home and Bluetooth speakers are always active, as they require power for their additional features. See: How do speakers work?

Watt really matters – facts about electrical performance

Powered speakers, also known as active speakers, are compact speakers commonly used for music listening at home, as monitors in music studios, and as PC speakers. Powered speakers have an amplifier built into the cabinet and do not need a separate amplifier. Powered speakers can be connected to music sources like CD players, turntables and computers directly. They are self-powered by their built-in amplifier.

How Much Amplifier Power Do I Need?

Music adds life to a social event. There are so many Bluetooth speakers on the market to choose from. The issue of wattage confuses many shoppers. Does wattage affect the loudness and clarity of a speaker? Should you go for a high watt rating and overlook the audio quality of the speaker? How many watts make a good speaker?
