Hello,
I am hoping someone can help me. I'm trying to build a speaker out of an existing enclosure. It's gonna be a small full ranger and I would like to help low end. I'm hoping I can do this by adding some kind of vent. However, figuring out this vent business is over my head. Can anyone assist?
Driver is a Fountek FR59EXE. Box is a cylinder with .014726 cu feet of internal volume... or .417 liters. Height is 2.5" and diameter is 3.6". Wall thickness is .5". Is there anymore information I can provide?

Well with no vent you get no bass below 200 Hz or so. If you add a vent tuned to say 120 Hz or so you will get more bass. The problem is that the driver basically is in free air below the tuning frequency of the port so signals below 100 Hz will send the driver flapping about. So if you add a vent make sure to use filter or EQ to protect it from the sub 100 Hz range.
That's one thing I did not want to do. My goal is to have a 2-3" full ranger playing smoothly across majority of range without eq or filter. Honestly, I'm not even sure what a filter even involves. Speakers are complicated.
This tiny driver is designed for a closed box.
Here is the manufacturer's closed box simulator for the FR59EXE:

how does a port make something that barely exists in the driver in the first place suddenly become a reality?
