OK, so this weekend I plan on building a ported box for my sub.
I have a Kenwood kfcxw12, and specs are found here..
Kenwood Excelon KFC-XW12 12" 4-ohm subwoofer at Crutchfield.com... I have a couple questions. I currently have a sealed box.
- how do I determine what I should tune my box port to? In looking for loudness that's not in any way harmful to the sub itself but the most bang possible and most efficient.
- and I've tried a couple calculators for ported boxes, and what does port length refer to after filling in volume, tuning frequency, port height/width,
- I see 2.68 is reccomended sq/f would be going a little bigger to maybe 2.3 have negative effects or no?
- and in a nutshell does the size of the port determine the tuning fq?
This will be in the trunk of a cobalt facing up, port possibly facing frontwards toward the cabin unless that's not recommend.
Thanks so much in advance!
