If you have enough brain cells left to hook up a home theatre system, how is it possible that it doesn't cross your mind that if you bring that stuff in your backyard, in a residential neighbourhood where there's a mere 10 ft between houses, you will piss off your neighbours?
 
I hate people.
 
 

But it does invite some creative revenge, ya?  Like starting a lawn mower AND a weed whacker next to the fence (using duct tape to keep them going) then leave both on and go inside for a while.

I swear to you that today is a particularly bad day. They wouldn't hear it.
 
I walked outside at 10 am with my book, hoping to read a few pages before starting my day.
There was this annoying poodle barking and he kept at it for at least half an hour.
He only stopped when that other neighbour started what sounded like a compressor or a pomp of some kind.
That went on for almost an hour. And it was LOUD.
In the meantime, I got back in.
When it stopped I got out again - only to be plagued by the idiot with the home theatre - at the exact moment I sat.
But that didn't last long as the compressor started again and drowned out everything else.
I walked back in again.
 
The darn compressor stopped 2 minutes ago - but at the very same moment, a bunch of guys w/ leaf blowers arrived to clean up a nearby backyard.

Ahh, the sounds of Summer. I am waiting impatiently for such sounds to fill the air. Been a long snowy winter here.
 
Still, I feel your pain. Been there a hundred times or more. Such is the price of living 10 feet or less from one's neighbors. Imagine being a day-sleeper like I was for years.
 
Even if one moves to a more reasonable 20 miles from one's neighbors, nature has a way of telling you to move back. Like when a family of ravens (avian loudest-obnoxius) build a nest right above your bedroom window.
 
Unfortunately, people are generally allowed to make noise in most communities between 8AM and 10PM. Most people are at work sometime during those hours so it doesn't bother them... especially if they're the ones making the noise. The rest of us have to just put up with it to a degree. If one or more noises "continue" to be a nuisance (like a dog that barks incessantly for no reason), you can probably report them to the proper authorities who may or may not do something about it.
 
Try wearing a pair of noise cancelling wireless headphones playing some sort of soothing melodious but non-hypnotic music. Or set up a set of phony surveillance cams around the perimeter.

That was going to be my suggestion too.  Anything "more appropriate" will probably get you arrested anyway. 

We've first noticed the TV thing last night. We didn't really bother as we were going back in.
 
There is no way I am putting on headphones to accommodate someone and yield to their absolute lack of discernment and good manners. 
 
I shall taunt them once and I shall taunt them a second time if I need to. Why do you think I have this outrageous accent?
 

 
Incidentally, there is such a stone wall between our respective backyards...

"I don't want to talk to you no more, you empty headed animal food trough wiper. I fart in your general direction."

Sorry, didn't notice the accent.
 
That's quite the outfit you're wearing. Are you a welder by trade?
 
Actually, posting a sentry at the wall fence might instill a bit of medieval fear in them. Tho it might be a bit more convincing if you gave him a lance or spear or caldron of boiling oil...
 
Seriously tho, I've found that talking peacefully to the neighbors about the noise usually works, tho it may take several conversations to get the point across. Retaliation only seems to worsen the matter. However, I did have to call Animal Control on one neighbor. He was as bad as his dog that he'd let loose to run around my yard mindlessly barking at everything and everyone at all hours of the day and night. Since a citation was issued I haven't seen much of either of them.

Outrageous accent can be heard in this quick video I did a while back to demonstrate a Logic feature I was particularly fond of.

I do agree that retaliation is not the best idea, not as a first option. No matter what, I pretty much always give people a chance to make up for any such things.

Maybe you need some of the people showing up at the Bundy Ranch in Nevada to help you out.
People, have no respect for neighbors, some of them.
