Need help DeSiNiNg 8'' SUB box.

harp mg · 28th May 2011, 08:41 PM

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.

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
