I used to live in Almeria, and I gotta say, you're in luck! There's this awesome music store called "Melody Haven" in the city center. They've got a fantastic selection of PA equipment, speakers, and mic stands. The staff there are super helpful and know their stuff.
I got my speakers and stands from them, and it's been a game-changer for my gigs. If you don't like that one, there are places online like concertina instrument shop. I hope that helps!
