How Much Power Do Speakers Need? | Home Theater Basics

[@davidmcarthur7029]

I'm 66 years old and have been a music lover from my Beach Boy days, still like a lot of what's on the market. I never knew what you taught today, so Big thanks. I'm retired and have a Sony receiver 7.1 rated at 125 watts per channel powering 5 speakers on surround sound, but I use only the 2 front Polk's on music setting. I sit 8 feet away. Speaker are rated at 89 sensitivity, so thanks to you I now understand I'm good for what I need in an apartment. ( Polk 10" subwoofer needs to be kept down till neighbors leave. LOL

Techno Dad love the way you use slides to present the information it makes it so easier to comprehend and to follow up step by step as you explain. You're a true Professor! Keep up the good work brother. 😀

[@alcozar5905]

Techno Dad this video is still amazing after years thank you.

[@TechnoDad]

@@alcozar5905 I’m so glad you like it!

[@robertholsopple9451]

This is where Cerwin Vega speakers excel. They have amazing sensitivity ratings. I have several vintage sets. Can't beat the way they look IMO. And if your too heavy on the volume knob, they are fused. Win win

[@TechnoDad]

Yup! I remember replacing a few fuses in the past, lol!

[@TheReggie35]

Thanks Techno Dad!! Out of the last 5 to 8 videos I just watched, to try to understand this, ur video is the only one that helped me to understand how much power I need to power my Klipsch speakers.

[@TechnoDad]

Awesome! Glad you liked it!

[@selenefroehlich9138]

you are the guy! I wachted soooo many videos that explain this, but they get waaay too geeky, your explanation is soo easy to understand, thanks for the work!

[@brandonculler8550]

I will never understand why anyone would give this a thumbs down. This was the best explanation & demonstration i have seen yet and one of my favorite Techno Dad videos. You mention at the end your going to do a follow up which how to decide which amp for a given speaker, did you ever get around that?

[@TechnoDad]

Hi Brandon, thank you so much! I'm glad you liked the video. I have not made that follow up. I guess this is a good time to do it then. Be on the look out my friend!

[@bingdong8571]

The biggest problem with this is sensitivity rating seem wildly inaccurate from a lot of speaker companies. Good thing you KZbin guys are here to give the real ratings. Thanks for the video

[@TechnoDad]

Yeah, that sensitivity thing can be an issue.

[@tahsinshamma2369]

[@almanages]

Congrat on your 100,000 man. It's stand with reason, this was one of your best video I've seen from you. You have some great videos in general but this time you actually hit another target of listeners,.I would say a notch above amateur audiophile. I think if you keep your videos simple and with the usual quality we are used to from you and bring-in the more advance audiophiles listeners with topics that actually interests these people you will certainly gain a broader audience in the process. Don' t get too technical but do keep your slides coming in with specs, we love that lol. Cheers Al

[@TechnoDad]

Thank you so much Al! I am definitely trying to get better with every video!

[@Mrtscrp30]

I really appreciate this video it helps me understand why the sound field on different surround settings can seem really good or total junk . i am not a pro so this bit of knowledge really opens my eyes personally on how to better calibrate the output of my receiver instead of just cranking up the volume and making my receiver get hot because i lack understanding of what i expect my speakers to do thank you very much.

[@TechnoDad]

Hi! No problem! I'm glad you like the video!

[@myfastcars]

WOW!! Very very enlightening!! Thank You! I'm completely NEW to home theater and you have save me TONS of cash even though I have NOT even purchased anything yet!!

[@TechnoDad]

Hi! Thanks for watching! It can be VERY confusing but at least they give us stats that we can use like speaker sensitivity. That's really the only way we will know how loud the speakers can get and how much power we need to send to them.

[@myfastcars]

Can you give me the title and author and where I can get the SONG that you use in the JUMP portion of all your videos? I LOVE it and want to own load it.

[@rags015]

Klipsch speakers use a dishonest measuring system. Their measurements are made half in-room and half anechoic something!! The actual sensitivity is 86db!! Nice video! Love your channel!

[@sudiptochakraborty1306]

You nailed it with the distance to dB reduction test! Just the piece of puzzle I was missing..thanks a lot!

[@TechnoDad]

[@Cblan1224]

All hail klipsch RP sensitivity ratings. Rp6000f&500SA's coming later today. Then 2 pb 2000s later in the week. I've been on stereo bookshelves for a few weeks now while I wheel and deal to get a more appropriate setup. My first setup was whatever I could afford. This is round 2. I got some great deals over black Friday (rp500c for 289) man going from the reference aluminum tweeters to these titanium ones...theres such an unbelievable difference. I actually had the rp500c on for a few days with some older reference bookshelves, and it blew everything else away. It was like my center channel was operating on another level of clarity, and once you hear it, you need it. Anyway. Thanks man

[@silverpantsblue.1780]

holy shit, I can not tell you how hard it has been for me to find this information. thanks for explaining this.

Hi! You're very welcome!

[@barryodriscoll4441]

Really good explanation, thank you. Love your use of slides

[@jimmyan1976]

nice video dude. internet is immersed with videos about wattage and ohm resistances but lack of sensitivity explanation, where this vid shine.

[@TechnoDad]

Thank you! I’m glad you found the video informative.

[@strobe9]

6:29 The inverse square law estimates -6db for every doubling of distance from the source. I'm no audio scientist but is the smaller amount of loss, measured with an SPL meter, due to reflections adding to the sound levels as opposed to an anechoic environment?

[@bradthurkle7217]

The very best video on this speaker info I’ve seen yet.thanks for putting so much effort and time into the research dude your a bloody legend.

Well you definitely want want to hear my set up its hits 138 dB at the couch if you go in the kitchen you can hear the plumbing rattling in the walls but that's the way I like I have a separate breaker for each of my 15" subwoofers.

[@MrSmith-zo6po]

Oh I have no doubt, sir. It sounds (pun intended) like quite an impressive setup. I love mine as well, and the loudest I have gotten up to was only a measly, puny little 112 dBs lol. I couldn't take that much sound for more than a few seconds...was watching War of the Worlds, tripod emergence sequence.

dayum! thats lot of wattage! haha thank you for the video. Im currently creating a home theatre.

[@AlexandruTataru]

Very instructive video however the THX value is all over the place. Let us say we have a 5 channel system with speakers of 87 db sensitivity. and placed 1m around the listener. This means that at THX continuous we need less than 5 watts to power the entire system, right? And in the case of THX peak value we need an amplifier/av receiver with 320 W of total power. And if the speakers are placed at 3m around the listener the values move to 20w continuous and ~1300 watts for THX peark value? Am I missing something?

[@number1pappy]

Wow!!....thank you so much!....I've never known this!...nobody has ever explained it this way as I now understand! This is awesome info especially given the wattage of the receivers I'm looking at! In the past I would just look for the biggest wattage rating of any particular speaker I was buying...I know understand why it's very important to know the sensitivity.

[@nobodynobody1235]

Now I understand this, but then I question what's the volume setting we set to hit that 88db or 98 db? My yamaha avr usually have this negative setting and i usually listen at -30db

[@gvanmedlin5567]

Nice job breaking it down for us. Thank you!

[@TexSupport]

Sorry to dig an old post. But ML spec sheet threw a wrench in what I learned here. My specs are listed at 94db@2.83 volts per 1 meter. Not the usual 1/1 ratio. So at 10ft. How would I compute this?

[@danielodhiambo1065]

Thanks a lot, that was really informative. I have learnt a lot.

[@chrisSkylin3]

George Lucas is THX certified deaf at 105db.

[@blueboyblue]

It is actually 85db with 20db Headroom (85 + 20 = 105db). 105db is the peak value, not the average. Also, this is 115db for the Subwoofers, and those level are all at the listening position, not at 1 meter.

[@bthellam]

I was definitely wondering hard at that 105 dB figure. Too loud for a living room my size. Normal speaking voices are around 60 dB and my voice is big and loud without shouting, so probably 70-80. I think 90-something (less than 100) would be plenty loud in there. Maybe 105 dB peak with all speakers including sub going in the room? (My wife wouldn't tolerate that!)

[@sushiking56]

I don’t get the joke

[@franklandgraff1190]

75 - 80 db is my comfort zone!

[@hammerjoe2008]

Something that wasn't mentioned in the video was if during his test if he used only one speaker or if two or more are actually playing. That would have an impact in the readings right? Several speakers playing will sound louder than just one speaker right?

[@B.B.Digital_Forest]

Hi. If we are to follow the decibel charts then anything above 70 dB is noticeably loud. Like alarm clocks, construction noise, and vacuum cleaners. The Denon AVR-x2700H supposedly uses 95w at 8 ohms (for 2-channel driven speakers). In a small room environment, wouldn't the listener need little wattage to hear if seated at 2 meters minimum? Given that I'll be setting up my first hi-fi system in an open plan space, I'm sure my housemates and neighbors will hear it if I push to 90 dB. I don't get why some reviews say some A/V receivers offer little power if it doesn't take much to fill in a small room. How big do audiophiles prefer their spaces to be?

[@feelgeorge]

How to match speakers and amplifiers video? Cant find it, did you make a follow up video to this as you promised?

[@alexd8007]

Or do I need a external amp for the external bluetooth speaker?

[@theministryofbreaks]

Excellent video, I never knew the sensitivity rating but I quickly started looking at them...Elac vs Martin Logan where it’s 85/86 vs 92. Still it seems for small rooms/dens you probably can cut a few corners and be fine with a set of Elac B6.2 as an example.

[@CraigLafferty]

Incredible information here! Taught me a lot!

[@TechnoDad]

Awesome! Thank you for letting me know!

[@fusion_fever1592]

Hi sir I got most part of your vdo, but I have one serious doubt and its bothering me a lot,so you mentioned a low sensitivity speaker will have around 88db@1w@1mtr, 91db@2w, 94db@4w, 97db@8w, 100db@16w, So the same speaker Will have 6ohm,10watt on the backside,does that mean it will produce 97-100db(lies between 8w-16w from the above chart) at 10watt at 1mtr distance.

Hi bro, I'm first time building a speaker on my own. I have 100w 2.0 Apm that will power 50w/channel. for 3 way crossover i chosen: woofer - 40w mids - 15w tweeter - 15w all are 8ohms (i have option to go for 4ohms) What do you think, in total 60w for speakers is too much or how should i choose mids and tweeter power?

[@andrewanderson3746]

What power amp would you recommend for a stereo pair of 87db speakers?

[@titodavila6734]

Hi Techno Dad, thank you very much for the video! I saw your other video about the benefits of adding an external amp. If you have high efficiency speakers, like the Klipsh in your video, and are getting 105 dB with 16 watts at your listening position, do you still need an external amp for your receiver? It seems that any midrange AVR should be able to do the job, although the power would be less than the RMS power spec for those Klipshs. I have a 5.1.2 set up with Klipsh reference speakers and a Yamaha Rx-A770, and thinking about upgrading to denon 3700h with an external amp. Any feedback would be appreaciated!!

[@RahulSingh-vn1bv]

Hi There .. i am running onkyo Nr 656 7.1 channel with one Klipsch 440c , two r 62 f and four r51 , do i need to add power amplifier on my system.

How long do speakers last if you use them regularly without abusing them (meaning listening to them too loud to the point of distortion)?

[@raider3164]

Question from a newbie. Why do avr say 145watts per channel. If u only need the say 65 watts to power m. Also how much real power is going to the speakers from the avr

[@batistacardozo1761]

I am considering buying the Elac uni- fi 2 un52 speakers. Can you help me select a good AV receiver and subwoofer to match these speakers. I am looking for a 2.1 system. My room is 5m x 7m x3m height.

[@bthellam]

One of the main things I'm wondering in this test, though, is how to measure the wattage being delivered to the speakers. Aside from that, understand this is coming from a guitarist and pro audio guy, every individual driver is given specs including sensitivity rating. Speaker towers tend to have woofers and tweeters--more than one driver per tower. What is the sensitivity for each one? How is that different from measuring the sensitivity for the whole unit? They never tell us room specs or which sound meter they use.

[@alexandrusarion8381]

Anyone knkw the db of the party speaker QFX PBX-8? Been trying to find but it only tells me there is a 1500 watt, and it doesnt say if that the max or not

[@jeffersononetwo]

Awesome video ... for this reason, I just bought a 2019 Marantz AVR with rated 50 watt (page 10 of manual says 70 x 7 channels and does not mention ohms). Anyway, I found that indeed, 50 or 70 watts was plenty of power to hit the same volume as I had with my 90 watt/ch Yamaha. My speakers are 90db sensitivity in-walls. Let me see if I can understand this a little more: in your case, you get 99db @ 1 meter and lose about 3db per meter beyond that for the same wattage at the couch. I wonder what wattage it was to get those numbers? Was it 1 watt @ 1 meter, 2 watts @ 2 meters, and approximately 4 watts at the couch? I'm thinking you would have to double the wattage for every meter you are beyond the speaker ... 3 meters away so double wattage twice. I am thinking in terms of how much wattage needs to be applied - and sound intensity is what I'm after. By this then, if you double the distance (1 meter to 2 meters) then you cut the sound intensity to 93db at the microphone and at 3 meters it should about 89db at the couch with the same applied wattage of 1. To get from 89db up to 92db at the couch you would need to double the power to 2 watts, up to 95db would be 4 watts, 98db would be 16 watts, and 101db at the couch would be 256 watts. 101db to 105db sounds about right - I really like the empirical measurements you took with the meter. In real life, a quality 50 watt or 70 watt is plenty of power - the more would give more headroom, but my rule is in lower watts, go with quality watts. Thanks for the vid!

[@zohebahmad2421]

hi in my home theater amplifier of model panasonic SA-KA66 it shows f61 error when i on it ,,i dont know what to do ..please help me

[@as0906]

So if my speakers are 94db @1 watt/meter and my AVR is 70watts per channel that means I'm capable of turning the speakers up to 112db without distortion/problems? What if I went over that? Blown?

[@syedjunaidkhalid1011]

Hey, a lot of sellers dont even mention sensitivity ratings. Why is that ?

[@jonseymour1866]

Well, my denon avr-x2500h says it has 95watts per channel driving 2 channels but doesnt state how much it has per channel if i have it in multi channel stereo driving all 7.1 channels

[@swinde]

The higher wattage of an amplifier mainly comes into play at the peak volume of the musical piece. I have fairly low efficiency speaker in the AR-3a model. It will handle 11 watts rms continuously an any frequency, 23 watts for 30 seconds, and overloads of 400 watts for 2 seconds. These are pure sine waves. The manufacturer recommends a minimum of 25 watts to operate these speakers. I power these with a Marantz model 250M power amplifier, so there is plenty of headroom.

[@TechnoDad]

Nice setup!

[@swinde]

Thank you, If you are interested the rest of the system includes the Marantz 3300 preamp, Marantz 120 AM/FM tuner, Thorens TD-125 turntable with Rabco SL-8E tone arm, Revox A-77 Open reel recorder, Advent model 100A Dolby noise reduction, Biamp stereo octave equalizer, Sony CDP-302 CD player, a couple of HD FM radio tuners, and a couple of cassette decks. There is also a Russound Patch Bay. Most of these were purchased in the early 1970s. The CD player in 1985.

[@alexd8007]

What do you reccomend

[@shinyamato]

So basically denon 2600 watt rating 95 driven 2ch can powered up klipsch front speaker rf-820f 150w 96db sens for just listening 85db ?

[@savanp228]

I need your help. I have two rp26 klipsch towers, rp440 center, r3650wii side surround and 2 back surround and 2 atmos with 2 svs subs - so 7.2.2 Atmos Running them on marantz sr7012. I am trying to buy power amp emotiva a-5175 - do you think that is worth it for more power? Thanks!!

[@GucciGamerTV]

OK. So now I’m confused. You corrected yourself and said that THX reference level is actually 85 dBA continuous. And this doesn’t include subwoofer output. So if 85 dBA on the speakers is only needed to achieve reference levels, it looks like no matter the speaker, as long as it’s 86 sensitivity on the chart is using 2 watts or less? Doesn’t seem right.

[@TechnoDad]

Yeah, but that's only from one meter away.

[@isa123125]

So if I have 91db sensitivity speakers and turn up the volume on my AVR to 55db, does that mean I am not using even 1 watt of power?

[@bilalmughal6604]

Sir i have kenwood da-1100ex stero integrated amplifiers but tell me what type of spekrs can run on my amp perfectely amp watts is 320 power consumption

Hi Chana, I am from australia and I have been watching your home theatre series and I really like it. I purchased klipsch RP 6000F along with Denon AVC-X3700H for my new soon to be ready house. I am planning for 5.2.4 My room size is about 5mts height 3.4 mts width and 2.7 height. My preferred seating is at 3.5mts. 105dB THX reference level is way too high for me. I would only need 75dB at my seating position. I have few questions. As per your video do you think I would need an external amplifier? As per my calculations each speaker will need less than one watt. Is that correct? So, doI need to do the same calculations for the surround speakers as well?

[@curtislaketek2952]

Very nice info thanks, i just returned my Klipsch 820Fs. I replaced them with KEF Q750, these are paired with Def Techs. Rears are BPX, Sides are BP7006s. Center is CLR 3000, and towers are now KEF Q750 towers. All powered by Denon 2600H receiver. Very happy now, would you recommend a second amp to power the towers separate? I have two extra amps not being used

[@gondokist]

(for home application) if we use an active subwoofer will it still draw power from the amplifier and still have to formulated first or just plug it in into a pairs of the socket (back L & R maybe) since it already have it own power source??

[@TechnoDad]

Hi! So you plug the sub to the subwoofer pre-out on the back of the AVR, you aren't powering the sub from the AVR, it's just sending a signal through an RCA cable. The sub needs to be plugged into power. I explain all that in this video: kzbin.info/www/bejne/d5yrinesq71lb6M

[@chrishefner3869]

The THX level of db is likely to allow headroom and remove concerns of distortion for volumes under that. The loudest I have tested my speakers at was 101 db and that would not have been a pleasant environment to listen in.

This is so interesting. Im about to get the klipsch 8000f. And i sit about 12 feet away from screen. At a really loud point ive measured 85db listening level creeping to 90db. Im running a yamaha rx660 which measures 80w 8 ohms 20/20 2 channel Driven. Except of course im running it at 5.1 so i have no idea the 5.1 power output. Going back the klipsch am i correct in assuming all i need is 2 to 4 watts to run the klipsch st 85db max?

[@bharathg8072]

Question, my speakers sound good but only after some time of playing audio. Especially the low end you can feel it after some time of playing but soon after I turn it on it's not as good. Suggestions on how to fix this or is this normal?

[@TechnoDad]

Are the speakers brand new? There is a theory of a break-in period. Since the drivers actually move in and out the will get better after some music is played through them.

[@boricuaspr]

I prob won’t get a response due the age of the video. But I want to try. I have a set of JAMO S606 standing towers rated @ 89dB, 6 Ohms, 130 RMS /230 Watt Peak. I used your calculations to get an estimate of how much power I need to in order to hit desired dB’s... my listening positions is 5 meters. Used an average of 3.3 dBs lost for every meter. Thats 17 dBs to hit 89dBs on my listening position. Now, I want to know if I did the calculation correctly. I subtracted 17 dBs from the 89 dBs to get 72 dBs using 1 watt. That means that on my listening position with 1 watt I will only hear 72 dBs. Now doubling the power for every 3 dBs puts my speakers 2,048 watts for 105 dBs. Thats an insane amount of power. But... my speaker is rated at 130 RMS and from the calculation means that I wont be able to listen no more than 93 dBs without damaging the speakers. does my calculations seem right? my current AVR is 90w @ 8 Ohms, not sure how much is pushes at 6 Ohms...

[@iammaximus614]

No sound check with the Decibel meter?

[@TimpBizkit]

I have 300 watts per channel into speakers with sensitivity between 98 and 104dB and 300 Watts per channel into subwoofers with 96dB sensitivity each combined 99dB sensitivity and the corner increases that to 110 dB sensitivity.

thanks for this video I save my dollar dollar buying a new amp..I just got Paradigm Prestige 85F and Im using my old amp thats push "85w" per channel Pionner Elite SX-S30 I love how it sound and they go pretty loud on 80% volume which I dont really do on regular basis..But im on the market on buying a new amp and I came across with your video. I guess I dont need it anymore..

But how about any sonic compromise at very high sensitivity?

[@Anonymous-sb9rr]

I've always found the Klipsch sensitivity ratings hard to believe. Could you do an A/B test with the Klipsch and some other speaker to see how much difference it makes? Use any speaker with a "normal" sensitivity rating of 86 to 90 dB.

That’s an interesting test. I might do that, thanks!

Very very helpful info. As per ur say we need good sensitivity speaker than a high power receiver or amp.

[@chrisvaladez925]

If by adjusting the distance through AVR, the higher the distance, mean more power to speakers? Meaning, 10ft setup can increase the wattage?? Thanks

Hi Chris. You don't necessarily want to do that because it's going to mess up the time alignment of the sound coming from each speaker to your main listening position.
