need good portable speaker recommendation

I am just starting out to play with a S2mk2, I know you can play with computer speakers or anything really, but I just want to know for someone that doesn't have a room dedicated to dj gear, and want to practice playing stuff, what portable speaker would you recommend.

i am thinking of the ion portable bluetooth speaker that amazon has on sale right now, what do you guys think?

How much are you willing to spend?

as little as possible, but I also don't want to end up buying junk.

If you want something cheap and portable I'd get like a refurbished JamBox or something

They're like 70 bucks on amazon

M-audio makes decent monitors for cheap and sound decent... Or spend a bit on a powered pa setup
