I was thinking and thing about it and eventually the amount of garbage thrown around my room was overwhelming and the only solution was to put all that garbage in trash or into some kind enclosure. Well, I decided the later and the MiniMe project is on it’s way. So, 3 days back I met my machinist and gave him all drowning of MineMe, placing the order. Since I finally went for G10 material it will take for a while – perhaps 2-3 weeks to have it done. Ok, I am not in hurry…

I decided to use juts one port and it will be 2” post, if I target 40Hz then it will be not too long pipe – approximately 3-4 inch. I will be using doable-flared port made from ABS. What inters me is if the port flare and the port’s pipe need to be mass-loaded or something like this? The pipe and the flare will care quite strong back and force reaction, so why do not make it from heavier mater then just flimsy ABS? Sure I will not re-do the port from bronze but I wonder if it makes sense to beef up the port, wrapping up some wavy staffing among it. I have quite good result from past what I was calming down horns by wrapping belts around them inner-layered with lead. Does it make sense to use the same techniques for the plastic elements of port?
