Hi! i am considering of buying the ADAM p11a monitors. i have mixed on them and i enjoyed it very much. i have noticed one thing that realy bothered me. the front ports make a flapping noise on bass notes. so when i tried recording bass or tuning a kick drum i got extra high frequencies coming form the bass port that were not part of the sound. am i overly sensitive? or has anyone else experienced this as a problem? i have also heard that ADAM have nother port design wich gives a shorter bass responce and makes the bass tighter and apparently reduces the bass flapping sound. has anyone had experience with that?
