Choosing Box

[lpman18 10+ year member]

i need some help, i have one 12 inch power akoustic sub ( ya i kno it aint that great) but i have it in a bandpass box which *****. well i bought a new amp and put it in but i didnt really get wat i had expected out of it so i'm thinking it probably the box. Do u think it would be better for me to go with a sealed or ported encloser?

the sub is

Power Akoustic Fubr-12

700 rms

help would be appreciated. thanks

The Fubr is made for a large ported box. The recommended size is 2.2c/f after displacement. A 4"diamiter port (10.25in long). It can also be safely used in a 1c/f sealed box but it wont be as loud.
