Normal
All vented systems exhibit low excursion around the vent tuning frequency.In your case, 65l with a 10.1cm port ~36cm long means that's around 29-30Hz, so if those were the kind of frequencies you were testing with then you're seeing entirely normal results.Try testing with tones around 40-50 Hz and see if excursion is more apparent.
