my first pair was PreSonus Eris 3.5 It was very solid. Highly recommended. I assume you mix with a headphone?

Bro, even if you have cheap speakers, acoustic treatment is very necessary as it can affect the percieved sound after the sound waves get deflected from your room walls.

I'm afraid this price range is better suitable for headphones :/ I first heard proper bass with 5inch speakers from Focal (~$500). Previously, I was on 4inch Monkey Bananas ($250), which sounded great, but didn't give me much of a critical feedback.
I'm naturally a fan of Presonus stuff and would check the mentioned Eris, but never heard them.
Anyway, no matter what you 'll buy, put it on stands. The difference between speakers on the table and lifted is enormous. Good luck with the choice!

yeah currently mixing in headphone until acoustic treatment is done, good tip on the stands. thanks!

If all you got is one hundred, I would highly recommend trying to find a used pair of ATH-m50x's somewhere. As somebody who has owned reasonably nice headphones and a good entry level set of studio monitors, this is the best cost-effective option I am aware of.

Otherwise, another option would be to get some ATH-r30x headphones, but they end in a quarter inch connector, so you would likely need to run them off of an audio interface of some sort and not a mobile device. Hope this helps.
