thats too small

on the web site it does say so i just found a sub close to it but what do they need

[RAM_Designs]

u want to do 4-4.5cuft per sub

likely subs forward, port(s) up will work best for you

35/36hz is great daily if u want lows with those subs while still playing higher well

This.

ok but i dont know how to tune a box

[theory1230]

12 sq inch of port per ft3 about 24 inch long works most of the time . Are you doing two or three subs ? I can run the design on WIN ISD. To fine tune it let me no I would do one chamber and one vent three vents will take up two mutch air space.

Depends on the size of the box and the desired tuning frequency. You may need more port and you may need to have a much longer port...just depends on the desired goals for the setup.

If you build box with .75 inch mdf 30hx48wx15d do a vent 102 sq in 18.25 inch long will tune to 34.8 hz works out to 4.25 ft3 per sub doing two drivers add . Vent is 8.5 x 12 18.25" long. You can do it right in the center facing up subs forward .
