I went the other way around haha. I used to have a cheap waterproof bluetooth speaker, but upgraded to a much better wall-powered speaker. Ikea sells white-labeled speakers made by Sonos, called ENEBY [1]. Their dual-woofer speaker was amazing for the price, on-par with something like a full size Homepod, for $90!

Unfortunately Ikea discontinued their larger version, and now sell Sonos/Ikea co-branded speakers instead with less drivers, and more money. They sound good, but not as good as their older, larger predecessors.
