You need some kind of filter anyway, so why not just run multi tone generator? Should be "annoying enough". 😀
Maybe an SD card audio player with 3 second burst multi tone sound with 1 second silence in between set on repeat when triggered.
Edit:
I am not so sure about using a piezo speaker though, depends what nets you the highest SPL, I would probably try a cheap compression driver.

A PVC pipe (or one for each piezo) can be used but it gives an more or less almost laser beam like, tight dispersion. For the piezo choice: there are these screw on type piezo horn drivers (1-3/8" ), these are probably the easiest to mount on a pipe. Or you could get cheap screw on horns as an alternative if the pipes don't work out. They don't have the same spl like the lemon squeezer ones but they work much better below 4kHz. That means, depending on what dispersion and spl you need favours the one or the other type.
For the piezos: They are very efficient, meaning they need hardly any power and they don't heat up because of that. They are vulnerable to over voltage which destroys the piezo ceramic and don't solder them (or just super super short!) because the heat destroys the structure of the ceramic, it will lose tons of spl. And you should put a serial resistor in front of them because they have a capacitor like impedance and that could cause the amp to oscillate.

A work colleague had trouble with his neighbours, he dismantled and cleaned his guns in the back garden, that seemed to resolve the issue. If I wanted to make a directional ( or better " beaming ") speaker, I'd mount 6 drivers in a circle. Another work college played Slayer, and latter Cyprus hill in conflict with his neighbours.

600db. I guess they'll say anything to get a sale...

A solicitor's letter threatening to sue for hefty compensation might work wonders. After all do they know a nuisance charge is hard to construct?
If their property is rented the letter goes to the landlord direct I reckon.

It is the owners of the property and I would say they have been on the wrong side of the law enough to know a fair bit about it.
I have seen those banggood.com horns, Guessing those numbers are a little bit contrived.
Guessing 600DB might be good for removing all concrete structures in the general vicinity.

Yeah, they will say literally anything. 600dB is physically not possible from such a horn, not even theoretically.
May I suggest even a different angle.
2 years ago one of my countrymen had a similar problem.
He rented a decent PA system (nothing like 130dB at 10m) and then played german military band music in the morning - loud.
The message was very prompty understood 😀
I guess hangovers and loud music does not go well together.

According to A Concise Decibel Comparison Chart From Electrical World an atomic bomb reaches 240-280dB.
I tried to find another reference as I seem to recall way back that somebody managed to reach 210 dB using a 15m horn construct.
This alone should suffice to disintegrate concrete.
But do not take this weak memory for a fact - it is more than 30 years since I read the article.
25$ for a small piece of metal, magnetic material and wires that can produce 32 orders of magnitude more sound than an atomic bomb - I wonder how this can be legal to sell or buy😛

The key to sending a message in my mind is to stop their own enjoyment of the music and not to create any additional annoyance to the neighbourhood that isn't linked to the music being played.
If I was broadcasting a loud tone, would it be possible to link the volume control of the amp to the volume of the music in more or less real time i.e. having the volume control linked to the SPL being picked up from the mic? Then between songs when there is silence or when they turn it down to hear where the tone is coming from it will also turn off.

I think you are going about this incorrectly. Is the AC mains feed to the house above or below ground? Around here the power meter is only secured with a simple tamper wire. Removing the wire allows removing the meter breaking the feed. But you probably don’t need to do any thing that nasty.
If you are both served from the same mains transformer, you might be able to overload it and have it shut down. Some around here have 15 second auto reset circuit breakers. Others use fuses which require the electric utility to do an on site service call.
A simple method to overload a transformer might be to connect electric heaters to all the individual circuits from your main panel.
I used to have a neighbor whose air conditioner would trip the common distribution transformer. That is when the utility changed the distribution transformer from a fused unit to a circuit breaker one. The neighbor still tripped the circuit breaker, but figured out his air conditioner was useless, so he got a new one.

Its not like that in Australia. Each house has its own switchboard mounted on the outside of the house (sometimes inside) with circuit breakers or fuses on all individual circuits plus a master fuse I think. You cannot cause a load on a common transformer.
My diagonally opposed neighbor has an artificial pond and he plays frogs calls on a loudspeaker almost all the time.
We called the city inspector a few times and incited our friends to do the same and it turned out that the level was close to the limit. The inspector visited them and they denied everything. They also have spot lights pointing at the house next door, they cannot sleep in the back bedrooms with both the lights and frogs noises!
Today I wasn't there but they are not playing it now.
Maybe cursing them is enough who knows?
Or build an artificial pond, hide an outdoor speaker and play the same frog song day and night just below the city limit.
As the perpetrator you will feel good and they will not laugh anymore!

Martin,
>I guess hangovers and loud music does not go well together.
Best idea so far; deprive them of their recovery time from a previous night of partying. Send over a case of cheap stuff anonymously the night before you've got everything setup to make it really hurt.
I believe the horns are pneumatic, in keeping with Railroad history. Engines had plenty of air pressure to hold off those Westinghouse brakes.
