Title says it, it's my first DIY subwoofer. I've made maybe 2 boxes total in the past for car audio, but nothing crazy at all. This project is posted on another forum as well but it seems that place doesn't get much traffic and the only person helping there is a mod (thanks Mike).
So far it's come out to 209 bucks for the amp+sub driver (shipped) and materials. I'll need a few more such as the porting, stuffing, etc. Talk about a budget subwoofer though :D
Mike used some software to determine the length of the port using a 4" flared port to reach output of around 19-21hz. He suggested I go with a total length of 17" for the box that is approximately 4 cu. ft. Question is, what is/should be the diameter of the actual port inside the box? Can I get away with 2" since that's what it seems that the original HSU VTF-3 HO subwoofer uses anyway. I assumed the 4" diameter was of the flared port itself, especially after going to Lowes today and seeing how big a 4" pvc pipe really is. Pics to come
PS Do I count the sub driver as part of the cost? My wife bought that for me :D
