How many watt is enough? What to do when matching amplifiers to speakers.

In November 2023, we published an article title "How Much Power Do I Need". When have many responses regarding the article. In the article we have talked about what NOT to do. In this video, George Taylor of Entracte Audio and I were talking what to do when matching amplifier and speakers.

2nd additional note on December 19, 2023 by George Taylor
Before too many folks go off the deep end over this video... the point of making this video - and creating the accompanying article - is to discuss the realities of power output specs and power handling specs. Those two sets of numbers are often used to sell equipment as opposed to defining actual performance. The "average " listener usual stays somewhere between 70-90dB. We carefully described what we consider to be "average" conditions, in which 50 watts of power is more than enough to meet those requirements.
However, we were also very careful to state that that speaker size and sensitivity, and that amplifier/speaker matching are important considerations. We are not trying to tell you how much power you need. Your room, your music, and your personal listening tastes will dictate that. There are folks with 3 watts per channel that enjoy their systems immensely, and equally many who enjoy hundreds of watts per channel. I have systems in my shop ranging from 25 watts per channel to over 300 watts per channel. They are all for different listeners, and different types of set ups. All of them are enjoyable in different ways.
At the end of the day we just want to make sure that people understand how to interpret product specifications a little better, so that they are better equipped to buy something that they will be happy with for a long period of time.

Remember! There is no specific certain limitations compulsory for anyone, just for anyone., its the absolute personal private choice to keep the personal margin of , Bass/Lows. Treble/highs. Vocal/ mids. So finally the out put volume as required to personal ""pleasant"" sound listening, wheather its movie,sports, music,or speech. Conclusion:- The sound must be pleasant, but: not loud with distortion.

I’m waiting for Angela-Gilbert’s video series: my favourite foods. Or follow me to my favourite take out restaurants.

[@angela-gilbert]

You really want to see that? I am planning to do some shorts of my food outing. Would that satisfy you as starter until I have enough time to do the main courses? 😁🤩

[@donalddeorio2237]

I have been into audio since I was 17, I'll be 65 in December. Only once did I blow up a tweeter, with a 30 watt pioneer receiver, with cheap speakers. Another time I bi-amplified a pair of Dahlquist DQ20I speakers with an Adcom glass 5500 on the bass and a Carver receiver for the high, 350watts and they sounded amazing.

[@greenlanternseven]

I wanted to enhance the logic of Angela Gilbert Yeung who uses tons of anti vibration silicone in the designs , I have done experiments using capacitors with and without anti acoustic caulking mounted on the bottom of each cap to damp the micro vibrations. ...it truly improves the sound dramatically

[@VirusForPrez]

What's that behind you guys (with all those colors) is it a Power Amplifier ? Looks awesome ...

[@angela-gilbert]

That is the NFS225-3 prototype power amp. A.k.a. Birthday Cake amp.

[@SymbolTech21]

You never heard about speakers protection circuit that are designed to protect the speakers if the amp will put on the output even 1v dc?

[@Jack96993]

6:30 I love watts/current 😊 I have an older Spectron musical MK lll class D amp designed by John Ulrich The beast weighs 54lbs and its output is 500watts@8ohm 650@4ohms and 1,200 watts@1ohm It bring my Maggie's to their knees I typically listen to music at 75 db with peaks in the low 80's What I like with that much current is the dynamic energy in the inner details and the grip it has on the bass, never mind how load it can play with no strain

[@simonirvine1628]

Depends on the mic stand, example = Latch Lake MicKing 1100 Microphone Stand. And that's for starters

[@angela-gilbert]

We were referring to the lowest price mic stand from Musican Friends for $9.99. We understand there are better quality and higher price products of the same kind in the market.

[@simonirvine1628]

@@angela-gilbert Fair Play..

[@Error2username]

What about those who lissen to "normal" level? Say max 80db in room? Would you rather have head room to the amp or run a smaler amp hard/warm? Thank you for sharing your knowledge👌

[@angela-gilbert]

80db is fairly quiet. I am going to make some assumption when I answer your question. Assuming you listen in a condo or apartment which loud music is not good for the neighbor, which result in 80db max. With a typical 88db to 90db sensitivity speaker, 30 watts would be more than plenty. That is 30 true good watts. Some mid fi to lo fi manufactures don't tell the truth but that's another story. Headroom is good but it also cost money and space, sometime generate heat too. There is a happy medium about having headroom or too much headroom. If you occasionally listen louder just for fun. Another 20 watts to total to 50 watts would be more than enough.

[@Error2username]

No i have a house, 80db is not quiet in my livingroom, its big towers tho from floor to ceeling, maby i need to recalibrate the db measuring tool?.

[@angela-gilbert]

@@Error2username If 80db is average it is loud. I assume the dB level was peak. Then you do need head room. How many watt is needed will depends on the speaker sensitivity and other factors.

[@michaelj.4187]

The bottom line, stress kills man and machine...

[@greenlanternseven]

P.P.S ...Angela Gilbert Yeung I was curious if you do valve designs for amplifiers?

[@angela-gilbert]

I use small signal tubes in line level components such as preamps and DAC. Not in the power amp. In term of power output in this video we were focus in mid finsolid state receiver area. We totally understand when it comes to higher end gears and tube amps, this theory need to adjust a lot. In fact, the colorful amp behind us is a 25 watt solid state power amp with 24.5 Farads of capacitance in the power supply plus other features. With the right speaker, it can do wonder. It is not something we can compare to any 100 watts receiver. Totally different games all together. Same applies to flee watt amps driving 100+dB horn speaker, not the same thing.

[@bobr9605]

Can I add an uneducated opinion here? I would say that the misconceived common belief that it is easier to blow speakers with two little power is due to the fact that most people experiencing the problem had too little driving power. Cost is the main reason. As you have pointed out its just as easy to do it either way it just happens more often because people try and push a lower cost under powered amp to do what it can't do. It happens more often because of the economics not the electronics.

[@angela-gilbert]

It is a very educated observation. Thank you.

[@georgetaylor3107]

You may call it uneducated, but it's very sensible.

[@reestyfarts]

My speakers have a nominal input rating of 200 watts with a 600 watt max., 88 dB sensitivity. They sound thin driven by 100 watts.

[@angela-gilbert]

That has nothing to do with not enough power. The quality of those 100 watts is more important than the quantity.

[@ivantrump4022]

Absolute nonsense. Unless you’re buying an amp that was designed by a 15 year old, the vast majority of amplifiers on the market, including those made in China, are operating at or close to their rated RMS power.

[@angela-gilbert]

@@ivantrump4022 Nice of you to assume all power are the same quality. If you only looking at the manufacture published number of wattages to make decision. Life is simple and much cheaper. Unfortunately, my life is a little more complex than that.

[@reestyfarts]

I am inclined to believe the speaker manufacturer's specs I cited. They are the world's largest builder of musical instruments. The speakers have 1.5 kg woofer coils.

[@angela-gilbert]

Whether the speake has bass or not has very little to nothing to do with the wattage rating of the speaker nor the amp. The speaker manufacturer may have rated their speaker correctly. It van still have thin bass because of either the amp and of the speaker quality.

[@n.lyndley.9889]

Can’t compete with AGY’s technical knowledge, but personally I prefer to use an amp that is mega powerful (and therefore not clipping, particularly transients) and use my brain. You’ll normally hear the if the bass driver is getting near its excursion limit).

[@angela-gilbert]

Having power for headroom is good. But there is a point where more power equal not as good sound. Depending on the speaker, that point can vary quite a bit. Also depends on the music type and the listener habit. Again, there is no one size fit all.

[@greenlanternseven]

My Quad tube 2's amp s are rated 15 watts each ....And they make my B&W speakers sound incredible and go as loud and clear as my 70 watt per ch Sansui Receiver model 7000 ,I think the B&Ws are rated 93 dB sensitivity. ..p.s Angela Gilbert Yeung stay away from street meat it has human D.N.A in it
