That is good to hear. Port foam shouldn't really cost that much whether they want to include it or make it an add on extra.
An new EQ to go along with the sealed response should help as well. Pierre has these at 5.9 on the preference score with EQ. If Neumi could get in that ballpark then it would definitely be one of the value leaders. For reference, there are only around 10 or so speakers that Amir has reviewed with a preference score that high. Before anyone says it, yes I understand the flaws in the score. Still as a metric it is impressive in this price range.
