So this project would contain Maelstrom 21" Subwoofer and Hypex DS 8.0 amp.
Here is a model, size would be about 700 tall with wooden legs, 650 mm depth and 1300 mm wide.
Idea with this is to do a band-bass box with t-line structure. The closed chamber would be around 150 liters and reflex chamber little over 200 with the space that t-line takes from it. Size of the square reflexport would be 100x300 mm and about 2,5 meters long (about 8 feet) and tone is around 13-14 Hz.
This is basically designed for watching movies and stuff, cutout will be probably around 30-35 hertz.
What do you guys think about this?
