Quick demonstration of what a box can do: (Video)

[Rashaddd 5,000+ posts]

Sub is a 10" TC OEM, SVC 4 ohm, powered by a bxi2607 (rated 800 rms @ 4 ohms)

Box is 3 cubes net (about 5x Vas of the sub), tuned to 27hz with 55sq in of port area (cone area = more like 45sq in), so port area = over 20% larger than cone area

Here's what happens on a 27hz tone: notice the amount of sub excursion relative to the enormous amount of port movement...despite a port that is larger than the effective cone area of the sub.

More to come with closer to 80sq in of port @ ~32hz, and then over 100 sq in of port @ ~38hz

Fs of the sub is 31hz

duct tape rules

the box is leaky as hell lol, even after my failed duct-taping attempt, it was salvaged and is my first box I ever built haha...port isn't even sealed off...so air even leaks around where the port attaches

ur just havin to much fun..lol
