    its not just port width that matters, its the combined area of the port. how the hell can your box be 5 inches wide?

    yes, this is true, but in general, the more port area, the more SPL

    you can certainly over do it though.

    if you can get bbp6 and learn how to use it correctly, it would serve as a good guide, but only a guide.

    look at no-wall boxes in dbdrag...alot of people go from 18"s to 15"s simply because they need more port....

    you can only learn by testing...like i just said, in NW you want ***-loads..but in street alot of people are using aeroports which certainly dont have shat for area...

    edit: thats a NW1-2 set-up...^^

    this is purely theoretical, but the actual difference in SPL should be somewhat accurate.

    Pink- 12 XXX, 1600 watts, tuned 40 Hz, 4 ft. ^3, 68.75 in. ^2 port area.

    Orange- 12 XXX, 1600 watts, tuned 40 Hz, 4 ft. ^3, 125 in.^2 port area.

    Re: port width lowest as possible for spl?

    its a tradeoff because of the enclosure is the biggest I can fit in my neons trunk. bigger port or less cub ft or other way around. Can I have to port outside of the enclosure instead of having it inside?? Or like half inside and half outside???

    yes..we run our aeroports out of the box...

    try a smaller box...do you have access to a meter besides at shows?

    i know you said it theoretical, im not trying to be a ****, but that doesnt account for impedance rise..which is a big factor when messing with volume/port legnth/port area/box placement...

    those programs are useless...like i said, get on a meter
