It's getting hot in there, it's messing with your tone! How power and heat changes your sound.

Excellent video. I think your explanation was very clear. Looking forward to the next vid in this series.

Great video. I used to build sub boxes back when I was in high school. We used software that determined the size of the box, port, etc. I constantly had to explain to people the difference between a sub designed for sound quality and a flat response versus a "boomin' system" that most high school kids want. They were always surprised to find that the bigger, boomier boxes cost less money. Once we had to completely seal up a trunk on a car because the volume of the trunk was too small for the box. But he wanted two 15" subs in his trunk. One guy wanted 8 15" subs in the bed of his pickup truck ported into the cabin. Holy cow...that was an insane install.

It is very interesting to hear a lot details. Normally I didn't care about a cabinet, I just plug in my guitar and make music. But since I watched your video channel I understand a lot more about the system amp and cabinets and about the tiny little things that makes the sounds I like. 🤘🙃

Really good explanation. I'm still trying to get a good understanding of the Thiele/Small parameters related to the actual physical phenomena that I know a bit better. Also your quest designing your own speakers makes for an amazing story to listen. I hope you keep sharing it.

I have sometimes wondered about Peltier cooling and heat pipes to get heat out of a sealed or insufficiently ventilated box. The solution seems to usually be distribution to extra transducers but that defocuses the sound origin. I guess it's about compromise.

Nice demo, thanks ... crazy idea ... think anyone ever made air or water cooled speakers, or maybe just with cooling fins etc?

Does the hump of a heated speaker interacts with its natural resonant peak? Depending on the speaker (55-75hz). The hump looks to be in the ballpark.

[@pharmerdavid1432]

The heat from hot tubes dries out the speaker cone, which I assumes was a good thing, possibly making speakers in combo amps sound better than extension cabinets? I notice my combo amps sound better after they're turned-on for awhile (30-60 minutes), but that could be from other factors. Interesting subject to contemplate!

[@BarefacedAudio]

I would hope that your speaker cone is already dry, they shouldn’t leave the factory until they are!

Great video! Your content is good enough to show my highschool level physics students :). Do you have teaching experience?

[@pharmerdavid1432]

Have you seen the dozens (hundreds?) of videos he's made?

[@NSRider24]

@@pharmerdavid1432 I have! He is always great with physics content.

So wait, just to be clear: The loss in power in the highs is the result of heat. OK, got it. But does the resonant bump have anything to do with the heat accumulation as well? Or does it only have to do with poor matching between a ported cab and a high Q speaker? Is the presence of both of these issues merely the unlucky result of playing a bad cabinet too loud? And, does this second issue aspect impact open-backed guitar cabinets as much as it does ported bass cabinets?

[@BarefacedAudio]

The increased temperature causes the unwanted resonant bump. So a cab with great sound and frequency response when cold could sound boomy/muddy/woolly/slow when the speaker(s) get hot.

Once y’all have affordable gravity drive engines and can directly resonate the gasses in a given area all this venting and voicing will be obsolete. Happy fusion humans unlimited energy is a nice thing to have around.
