18" BTL N2 Box Design

Recommended Posts

Alright, i made a rough sketch in google sketchup, not sized at all just random measurements but this is how i want it look, and the specifications i was thinking about using.

The port is partly external because i will be firing it through the rear deck of my car. Tell me what you guys think! (Still working on perfecting google sketchup)

Net volume ~ 8 cuft

Port Area = 144in2

Port Dimensions = 9 x 16 x 37 (length)

Tuning = 32hz

Sub will be facing up aswell as the port.

Fi recommends 4.5-8 cubic feet, do you know more about Fi subwoofers than Fi does? Are they doing something wrong? Damn you need to be on the payroll.

Do as you wish. Everything anbody post is just an opinion they may have. Having experience, but only 17 post i guess i wont get anywhere with anybody. You could have a complete dumb ass on the forum with alot more post than i have that would pry be heard more than me just because of post count.

..amount of power applied should correlate with box size..bigger doesn't always mean better or louder..

Efficiency increases and the need for more power decreases when using a large enclosure. Doesn't the frequency response flatten out as well?

Flatter response is typically better for musicality correct?

it means output is more even across a frequency range, as opposed to being "peaky". So yes, its more musical.
