[QUOTE="Ninteens, post: 2968452, member: 568403"] I designed that. Its basically a by the book ABC box, or Dual tuned bass reflex. I see a lot of you have questions regarding the extra baffle in the main chamber. Thats just there to try and eliminate standing waves. Its like 12in away from the port. All three ports are equal length, just like the ABC design calls for. The reason the near and far ports are differently angled is because, The air from the middle port would flow right into the near port. That couldn't be good for tuning. [/QUOTE]
