I'm pretty happy with these https://www.amazon.com/gp/product/B00UAFSN5O
Nice. I was thinking about doing this. My cabinet is coming next week. Here is what I’m going to try and get going.
Edifier PC speakers - https://www.amazon.com/gp/aw/d/B00UAFSN5O?psc=1&ref=ppx_pop_mob_b_asin_title
Monoprice Subwoofer - https://www.monoprice.com/product?p_id=33829
I tried it out last night and it sounded great. I hope the Edifier’s fit ok.
