[QUOTE="keep_hope_alive, post: 8406987, member: 576029"] When I get back to a computer I can forward some links and papers on the discussion port sizing and flares sizing. your port is based on frequency response of the enclosure and excursion of the driver. what we care about is port velocity. once we know it we can predict chuffing or other noises. that is what determines the minimum port size. the size of the enclosure has nothing to do with port velocity. Frequency response matters because lower frequencies move for air. the lower your enclosure is expected to play, the larger your port needs to be.
