Port help -- fiberglass Rl-i8 enclosure

[negativezeroz 5,000+ posts]

I am starting a fiberglass enclosure today for a Rl-i8. I don't have the sub yet but I want to get started anyways.

Basically, I want to port it low; atleast 30Hz. Since I haven't built the enclosure yet, I am shooting for around .75cf.

How big does the port need to be? Width and length. I think I'll just use PVC piping for the port..

I will update with pixzors and specs once I get rolling.

I would do a 3" port and for a 3" port tuned to 30hz do 26" long
