I watched your video on port tuning and i understand how you cut the port down till it peaks at 43hz but what determines 43Hz? Is that the res frequency of your car? I was just wondering becasue as you cut down the port the peak would change, i presume that when you cut down the port all burps were at 43Hz or did you run sweeps.

Hope that makes sense

Also what happened to the 8 flared port in the center idea? Thought about a 10 round port?

Loving the recones
You are correct in that I keep burping 43hz with the same settings volume amp etc.. till it peaks out. Currently my car peaks at 43-45hz so I tune my boxes accordingly.

Robs not ready yet for the dark side of SPL. He still has woofers to tear up and new ideas to try before becoming a Trunk SPL Jedi. A round port may gain big time for him and help with his loading issues.....
All of it is True! I still havent peaked out with the current design. I have however devised a plan to try aeros with current box. Im gonna try capping the port and put an aero in its place. 10in for certain. I may even build a box to try in the spring time.

I cut new sides and a top today. I also routered the left wall to fit flush with the face and the ring.

Kinda acts as a bandpass lowers my frequency 3hz.

also, the sub thats over the port wall breaks not because the port wall is too close but rather b/c that area pockets alot of air and it doesnt load insync with the other sub.
If the port is the width of the box will it make the bottom portion of the sub(s) load differently too, would it cause wobblin'?

Afterwards with 6 total batts I was able to put 180v musically for a whole song and never dropped below 14v without any sign of a clip light. Will get testing soon to see if it helped on the meter.
