i was wanting internal

Not figuring all the technical stuff and using the base dimensions.... that enclosure is 12.7037 cu. ft. Im sure it will be about 10 when all is said and done.

there not exact, but there close enough ( i used the styrofoam beads found in beanbag chairs) and took them out 1 cubic foot at a time)

im used to building sealed fiberglass enclosures......so thats the best method i know for irregular enclosures

I just went and looked at your build log... How do you plan on adding a slot port to a box that is already sealed up? Are you going to start over?

If it were me, I'd just run 'em sealed and brace the shit out of the box... or add aero's externally out the back and brace the shit out of the box... or start over with a well defined plan first.

You'll never achieve stellar results without first having a plan and sticking to it. It seems the port is an afterthought for you, when it should have been built into the design to begin with.

No disrespect intended, Sir.

just looking for a drop in/screw down port around 6" tall by 14" wide, i left a space open for the port, and you are one of the few people on here that is respectful, so its ok

you need about double that amount of port area (163.5 square inches to be exact, thats a minimum)

thats fine, i left a huge spot for port, what length for around 36-40 hz?

port needs to be external or it will screw everything up more than it already is

14" long

12" wide

and port length of 26.25"

that should be CLOSE to 35hz

i cannot give you an exact number because you cannot give me an exact internal volume

 

[GohillaAudio]

thats at 14x12?

 

[GohillaAudio]

could i do a variation of that mesurement? say....8" by 18"?

what would port lenght be to get me closer to 40hz?

yeah... iirc thats like 174 square inches of port area

but port length (depth) is 26.25" for 35hz (ish) tuning

i see people saying iirc alot...im not too good with internet lingo, whats that mean?

 

[dcole18 5,000+ posts]

do 9"x18"

and 16.75" of length
