as it says i’m looking for a bluetooth speaker for under 200, i really love going out and listening to music(really loudly) with my friends and need a new speaker so wondering if someo could recommend a speaker under 200 with a punchy base and very loud

So I work a lot, like 12 hour days, 6 to 7 days a week, and on the weekend at night there's like nobody here and I like to be able to listen to music through my shift while I work and restock and such, but every Bluetooth speaker I get isn't very loud, the problem is my work environment is just naturally loud (foundry) so trying to go over that noise and the sound of my forklift and stuff is a bit of a challenge. I don't want to wear earbuds as I need to monitor my radio and be aware of my surroundings while I operate machinery. Don't want something super expensive because it's gonna get dirty as shit too

I'd appreciate any help I can get :)

I'm looking for the loudest portable speaker that I could fit into my backpack. Any insight? I would prefer for it to be only a couple hundred dollars but I'm open to all recommendations.

Edit: my backpack is pretty small and will have other stuff in it so preferably the speaker would be roughly around the size of my old JBL Charge 4.
