The goal: make something that could shake the entire house, walls and floor, with good enough sound quality.
3 years ago I bought a subwoofer from a local shop, a 12 inches JBL Stage 122D, 250W RMS and 1000W peak, for a very good price. Good specs, sensitivity etc..
I had no way to use it at the time because I needed a proper enclosure but at some point I just realized I could use a simple yet effective to make a subwoofer without having to research anything super fancy or extraordinary.
Designed a ported box with a volume of 60 liters, tuning frequency of 28Hz and wide and narrow enough to fit in my living room.
For the wood I used 28mm thick planks, then cut everything to specs and made the hole with a jigsaw. Planks are held together by screws and wood glue, it doesn't go anywhere.
Then applied several coats of varnish, sanded and painted again to have a nice glossy finish.
Inside I put the usual foam, mounted input connectors (one for each coil), mounted the subwoofer and closed everything.
The finished subwoofer box is as wide as my kitchen table.
The result is quite amazing, even at low power all the windows of the house start to vibrate.
Turning up the volume a little bit will also make the floor and walls to vibrate, causing the furniture to shake and producing the same result as a low magnitude earthquake.
Was It a success? Well, I never had so many guests in my house for movie and music nights like I have now.
After some testing I ended up using this 1000w Mosfet Amplifier I repaired and showed in this article to power the subwoofer and connect it to the existing 7.1 audio system of the living room and the TV.
With that amplifier and this subwoofer I can feel frequencies down to 10Hz (not really hearing them, but you can feel them on your chest). Impressive.
DISCLAIMER: no chihuahuas were harmed during the production of this subwoofer. The fact that the neighbors were willing to let a dog bark indoor for half a day was enough to make me stop caring about annoying them too much xD.

Chihuahua's are the right size for internal enclosure damping.
LOL ! blast that little yipper.
Glad to hear your treating guest well.
With a single simple 12" sub. I entertained many guests years ago.
They loved it.
Amazing what one sub can do.

Have not seen Fish called Wanda in a long time. I was working at a Video Tape rental store when it came out.
If I remember Ken eventually took out the dogs and the old lady.
Piano gag sounds funny. It a endless stunt gag in old cartoons to meet your fate by piano movers dropping on accident.
Great idea to portray it in a film...... clunk boinng

Many years ago I had a neighbor that had TWO very annoying & loud barking chuwarwers >
I recorded their noise and then 'burnt' it as a CDR loop of significant duration >
then played it back [outside] using very loud PA speakers > they went totally crazy 😉

Nice, always had fun with the old Hewlett Packard Oscillator dad gave me.
Hook up a speaker or piezo tweeter and run up the frequency, till every dog in the neighborhood barked.
When we could hear it none of them cared. rolling up a little past audible it was like clockwork.
Every dog barked.
