[QUOTE="Jeffdachef, post: 8407156, member: 650438"] so lets say my 2 18s require a minimal of 192 sq inches of port area, how much higher/lower can I go before it starts impacting sound in a negative way? No flares involved. There's a very small and negligible margin of error because the surface area of each sub is different. However, it does land you in the proper ballpark each time. Great tool. *******To any newbie out there reading******** lets say an alpine type R or hdc3 18. Type R listed xmax specs is 20mm and the HDC3 18 is 36mm, Do not use those numbers, as they are two way travel. You need one way linear travel so divide it by two. You need to make sure you find the one way travel X max for any sub or else you'll end up with ungodly amounts of port area. [/QUOTE]
