Vent Mach DD9512

Wonder why it's max velocity is at its tuning frequency, where that is where it loses a lot of power.

Does that make sense? Lol

Ok something useful, here's a vent mach calculator. http://portsgalore.stefanhinote.com/?do=ventmach

Its amazing how difficult it is to search this subject on the net. I had to search and word this topic about 20 different ways to get enough info to fully understand., I tried to piece it all together the best I could to pass on the info in that topic above. This is a pretty importent aspect of box building that I often never see anyone mention or worry about.

I'm not really sure, anything else I find out I will contribute to this thread. i'm just glad I finally figured out some accurate and useful info on the subject because it is a vital part of how the sub will perform and sound.
