i learn so much from this video series. thank you!

Great stuff Paul! The physics behind this question aren't all that complicated but I think most of us don't realize that's just how it works:)

Thank you! I really enjoy the videos, and I learn a lot.

It is always amazing how Paul can make something out of a question any normal person would not know where to start. To illustrate, if this was about architecture: How do walls affect a house?

Excellent explanation. Thanks very much for another great vid! Paul, I’m gonna set up a tent, live in your garden, and live off of pizzas from your oven, btw. I’m sure you probably know this, but the original picture of Nipper had him sitting on his master’s casket. Kinda eerie.

Great intuitive vid. I learn so much from these vids. But all the info can be overwhelming for non audiophiles. Seeking the Best Sound is in the mind of the Beholder as it is generally subjective. And really trying to match different speakers with different Amps is also is a major project which will take lots of time, effort, patience.

This probably won't be seen, but I'm particularly wondering about the difference between the tall and slimmer floor-standing speakers, versus the more conventional (or now old-fashioned?) rectangle boxes that don't have a whole lot of cabinet below the area where the drivers are. - This often also makes the drivers in one of those "pillar" boxes smaller, like an array of 6" woofers, and the wider boxes of course allow for larger drivers, like 10-12-15 inch woofers. - I really wonder how they stack up to each other. - I have some of both types, but I can't really easily get them into the same room together. Besides, they sound too different from each other anyway.

Great answer for DIY projects building speaker cabinets.👍

A fine explanation indeed.

Welcome back to you "other home" good sir!

Cheers paul love you

This is the brilliance of transmission line speakers like PMC

Ultimate explaination

Oh, you plug in here The music round and round, whoa And it comes out here

I agree with Paul with sub woofer's you want them to hide in your system. I also agree that you have to find the right sub woofer for your system and it depends on what type of music you listen to. Bc you want it as if you were listening to the music live.

We should be open minded to the new concept of speakers enclosure design, that's it..

Sealed boxes have a "air spring" effect. The bigger the volume the less resistance your woofer/subfoofer gets, but they can't be too large then you bottom them out (unless you are talking about infinite baffle)

Long throw and short throw woofers?

Power ~ Volume.

Sup Paul!

Sadly, Nipper is standing on his master's casket.

How do I block ps audio?

Hi. I am from INDIA. I love your videos❤️❤️❤️ from which I learned a lot. I decided to build my own dual 3 way speakers for casual listening and bought some of the components for them, which is listed below. Could you suggest an good enclosure for it. I need it to be smaller. Components bought- 2*Tweeter - 250 watt. "3.15"inch 2*Mid range - 25-40 watt. "4"inch 2*Woofer - 10- 80 watt. "8"inch The above listed every drivers are 4ohms. 2*3 way crossover Stereo amplifier circuit (ic4440) 2*50watt output Bluetooth and usb module 12v 3 amps transformer Every design ideas are respected.

I find it strange Paul finds it “Uncomfortable” in his own company office.

Paul, please tell me each woofer in the IRS 5 has its own sealed chamber?!?!

I’ve come to prefer a closed box with DSP tuning and servo sub. The imprecision and boomy bass using bass reflex or transmission line; or the somewhat random room reflections using dipole are added effects that ruin most music I like.

I'd feel like I'd need to shower before sitting on that white cloth sofa.

Unused fireplace and chimney? Want a large sub enclosure.......?

When we going to see these new speakers you keep banging on about going to show us a picture or 2, really doesn't make much difference if you show them now or afterwards. did you sort out that bracing issue did you try two cross members shaped as a opposite triangle fastened in the middle. You should turn the box like any musical instruments try e flat (c) all rights received for tuning a speaker box patent pending. just in case you get some bright Ideas. The IRS 5 are they servo controlled and if are they originally digital or analogue servo feedback

Transmission lines are very interesting in their performance and as far as cabinet shapes asymmetrical or do you remember the focal egg

Cabinet turbulence is also important for ported enclosures that should be another vid lol

Pants. Please. Go put them on...
