Conecting portable speakers

[Joaompac]

Helo, I´m developing a project of a portable stereo speacker with a Subwoofer and three small speakers. I would like to know if there is a way to conect all this components without using wires. I´m surching for a conection similar to bluetooth

There are other similar wireless ethernet products avialable.

Google "wireless ethernet speaker adapter" or some variations of that.

Tend to be be expensive.

Linksys offered such a device years ago - worked fairly well but it was problematic and soon discontinued.

Probably holds for any products of the sort.
