I really like the video. Great video. I have a question for you: What items you need to measure the speaker sensitivity and how to do it? Thank you!
Great video, thanks Hans
Goeie video Hans!
Hans great job demystifying electricity, amp power and speaker efficiencies. I would enjoy a video dedicated just to tube amps, and what is required to drive speakers that are not horns, or less than 92dba. Logical pairing with tube amps has been high efficiency speakers, but it would be interesting if you could delve into this more, if you have not already done so. Kudos Hans!!!!
How does the calculation change when using a separately powered subwoofer with a pair of bookshelf speakers? (1) Would that typically reduce the amplification requirement for the bookshelf speakers by 10%, 50%, 90%? (2) How much does the answer depend on having a high-pass filter between the amp and the passive speakers?
This guy is the Carl Sagan of audiophiles.
Very interesting, indeed.
Yet, I am a bit confused. I am setting the loudness on the pre-amp, defining there the voltage and the current demanded from the power amp. Since the inputs from various sources (turntable, USB dac) are not the same, the loudness button on the preamp is in a way the instrument for getting enough SPL without demanding too much from the power amp. Am I right?
My loudspeakers recommend amps form 30 to 250 W, my amp delivers only 50 Watt, so I am actually at a limit for listening to classical music at an average of about 80 db. This is where I have to believe my ears…
"Life sucks and the you die..!!!!" Wonderful video, thank you… Would you do a video explaining and interpreting VU meters..?

It's like watching Sheldon and his flag-episodes on Youtube.
Can you wrap a speaker to increase watt? And how to calculate speaker wattage?
Great video!
If a 300 watt 8 ohm speaker/cabinet is parallel wired to a separate 300 watt 8 ohm speaker/cabinet (reducing the load to 4 ohms) then hooked up to a 600 watts per channel (@ 4 ohms) amp, how many watts (if run at full power/600 watts) would the amp deliver to 'each speaker' please? (This speaker load would be the same for the second amp channel also = 4 cabinets/2 cabinets per channel)
If running 2 x 300 watt speakers (per channel) in parallel, what wattage amplifier would be ideal please?
Thanks for your goodwork sir. But this Excel tells that i need 300watt for 90db average listening with a 86db sensitive speaker in classical music. Does it mean all of us using 100watt amplifiers will burn our tweeters when listening to classical music?
very well done hans thank you from florida usa
So, under powered speakers are more likely to be damaged by a "clipped" audio signal than if the amp had enough reserve power??
sir .. you're an angel.
Are there any good passive sub-woofers out there anymore? Or at least any powered that use AB amplification, instead of these class D's?
Yamaha handbook separates sensitivity and efficiency. Efficiency needs to take into account the angle of spreading of sound.
You are genius sir.
If my receiver producers 105 watt par channel and my speaker comfortable wait 20 watt to 100 watt per channel what happened????? It is comfortable or not!!!!!!!!!
Hi!. When you speak of headroom does that mean that the amp will be able to reproduce the extra Dbs without any clipping or distortion or strain? So if I want to listen to my music at 83db from my listening position the amp will get to 103 at peak times without any issues? 🙂
Thanks for the information.
Glad somebody made a beautiful rendering in making one understand speaker wattage to match an Amp
Would be great if you could throw some light on RMS and PEAK watts for the Audience as the marketing companies have started to misunderstand customers
tI have fast track c600 audio interface and focal cms 50 monitor speakar and it works fine .Do i need to worry about anything?Thank you for your information.
informative sir..thanks
question sir…it is ok if used for a dual 21" sub 5k watts per channel of a amplifier 10k watts stereo for mobile dj application..
