Man, I love the way you teach.... so damn good.

[ghart]

You rock. You have increased by knowledge of HT so much from your videos.

Kirk: "Scotty, I need more power"
Scotty: How much captain?
Kirk: "Give me everything you've got!"

Nice illustration and useful information but it's unfortunate you don't account for multiple or all speakers playing in the room simultaneously which significantly adds sound pressure and reduces the required power you show to hit 105dB. Multiple uncorrelated sources add as a sum of the squares. Going from 1 speaker driven to 11 driven in a room can add as much as 10dB total SPL! The peak SPL of 105dB per speaker you reference typically isn't a problem for a really good receiver that has plenty of headroom in the power supply to deliver enough momentary power to hit that # on a moderately sensitive speaker. Anyway good info and separates are the way for the ultimate experience of course ;)

Such a important video first of its kind. Thank you for making 👍🏻🙏🏻

[ubermenschen]

Really good stuff to know, stuff that helps you size amp and speaker.

[BoyGenius-]

The bass kick. Love it. I’m convinced it was the speaker upgrade because I couldn’t get there with my old Klipsch speakers. Can wait for that video.

[TriforceofShadows]

Finally understand power requirements for load. Very clear description. Thank you very much!

[FURognar]

excellent video! this is a very important topic.

I have clipped my receiver due to a lack of adequate power for inefficient speakers (86db heights and 87db surrounds) but that was before I added subs....my fronts were trying to produce bass frequencies so ran short of power. since I added the subs I havent had an issue with it but also I dont listen higher than -10db

The DIY speakers in my theater are insanely sensitive. They hit 100dB easily, it's crazy! My front stage is MTX TP2400s and they need a separate amp to get reference levels. Like you, I don't ever go 0.0dB. But it's nice when 130dB gets pegged (because of subwoofers). It's a good feeling.

FANTASTIC video!!!

Makes me feel better about going with the PSA speakers. at 98db sensitivity they sip on power.

My modest and simple home theater: Onkyo TX-RZ50, 2 Subwoofers Rel T/7x, Center Speaker Dali Opticon Vokal 2, Bookshelf KEF LS550 META, Rockville RS29W Speaker Stand 4 Surround Speakers POLK TL1 . I'm happy with the quality of Sound I have, I don take any measure, but thank' you for your video

[mikerouth]

Your videos are very informative and the information is very well delivered. You gained a subscriber!

[Quetzalcoatl]

Great video! Nothing to add, nothing to remove!

[danielseguin]

Very well explained. Thanks for sharing!

[Hitokiri_Ace]

Nice, learned a lot from this video. Thanks for the time and effort. :)
I ran some napkin calculations.. and I can run reference across the board.
Pretty crazy what higher sensitivity speakers can do.


Looking forward to watching more of your content and learning as I go. :)
Thanks again, have a good day!

[aladdinjammal]

Thanks for the video
I have klipsch RF7 III and RC64 III
They claim 100db sensitivity
The speakers are 4 meters away from my listening position so for one watt at 4m I get 88db, so I need 32w to get 103db at 4m ?
For now I just have those 3 channels (later on I will add surrounds and atmos) on my denon x4500h which delivers 125w for 2 channels driven.
Do you think it’s enough for now or I need more power for headroom ?

It is important not to forget, how much sound you loose with an acoustic transparent screen with the additional black layer. Even with the best ones it is a 1, 5-2dB loss...
