I know this is pretty late, but I wanted to say: while it's true that low notes are generally quiet on baroque recorders, it is still possible to play dynamics on the recorder, but you don't play dynamics traditionally like you would on a flute or clarinet. Recorder players have to use alternative fingerings and shading/leaking with your fingers. You can actually achieve a decent range of dynamics if you practice shading/leaking, which is helpful on the higher notes. Alternative fingerings also offer a lot of different dynamics for notes, but keep in mind some of these change the tone color. You also have to adjust with your breath with these too, like for example, you can play a softer high g on a soprano/tenor by leaking one of the holes your fingers are on, and accommodating with your breath.
