I understand that the 4430 cabinet, with two ports that are about 4" in diameter and about 8" deep, is tuned to about 34 Hertz. I have also read that it is is desirable to re-tune the cabinet to about 29-30 Hz, by closing off one port and shortening the second port to about 4" in length.
I don't want to cut up my port tubes, and it looks like removing one of them (to replace it with a shorter one) might be a little destructive.
What if I just blocked one of the ports and left the other alone? I did see Zilch suggested that as a possible approach. What would that do to the tuning? I may just try it and see. Any other thoughts? Thanks.
(Disclaimer: OK, I admit it: I think they sound great as they are. I just like tweaking, but I don't want to damage the speakers in the process.)
(Confession: I also posted this question over on AK.)
