I bought the same speakers that the @mntmn Pocket Reform uses (CUI CES-36181118PM67) and installed them into my MNT Reform following a mod that Lukas had already performed. My first attempt fried my audio chip (reason unknown -- i was probably not careful enough with the cabling) but now it worked! To save space, I routed the cables between motherboard and keyboard. These speakers are finally proper loud. 📢 🎉
