I'm going to leave my speakers on late at night
What is your reason for wanting to leave your speakers on late at night?
I want to annoy my neighbors, after their dog's barking burns my ears.
They should quiet their dogs. It's not cool to disrupt other neighbors, though, just to get even.
It's a good way to get back at them. They should have hushed their hound.
Trying to get back at your neighbors is not something that is going to help this situation. If you have asked them to keep their dogs quiet and it hasn't worked i understand why that would be frustrating. However trying to be loud as well as a way to get back is not going to be helpful.
