PA System for home studio

Hello, i'm building my home studio and would like to buy a PA System, main use would be playing with my synths / keyboards (Korg SV2A / Virus TI2 / Moog Subs37).

My studio is about 17square meters, and i was considering buying the LD System Dave 8 XS or the DB Technologies ES503.
Wich one should i buy?

Thank you!
