Unhappy Need help DeSiNiNg 8'' SUB box.

i am not getting satisfied with my small sub at home i want it to be stronger some how. i think there is a vast effect on the bass by the sub box . so i need u to help.

i dont know what are those parameters that they use when calculating enclosure so if you could just explain me about the parameters that i need to know when calculating a sub box in both ported and other types eather.

my freqenzees are 20 to 80 Hz that i think is good for making things rattle.
huh i know my sub is small but i wanna get an extreme shaking bass from 8'' sub. tell me if i need to increase number of drivers. Power is about 70 to 100 W

problem is small diameter subs dont play low, no matter how good the box or how many drivers.

this will get you started. Id start with 1 cufoot box and a 4" port.

in their recommended vented box with 200 watts would get you there. If you cant build a box you can get one there too.

I have their 15" and i can rattle the walls with very little power, so their 10" should be more then enough for a small room.

If you want to just buy a home sub this one is nice, and has free shipping
