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

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

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. 😀

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

[brandonculler]

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?

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.

[alcozar]

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

[selenefroehlich]

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!

[tahsinshamma]

You're a man after my own heart. Presenting info in a clear way, really helping people make informed choices! Awesome!

[rags]

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!

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

[tenn]

FYI I’ve watched this video 5 separate times... great vid man

[Mrtscrp]

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.

[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

[MancaveCentral]

That was actually informative, good job.

[sudiptochakraborty]

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

[jimmykent]

Just found your channel. Dude, you are very talented at making complicated concepts easy to understand. Bravo!

[jimmyan]

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

[silverpantsblue.]

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

[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!!
