I did say it should be two times the width of the port so as not to affect the tuning frequency. It has to be at least one port width away to keep from obstructing the airflow. Think about it this way. If the end of the port is exactly one port width away, it will extend the effective length of the port. You can use this to your advantage sometimes to get a longer port. You need to plan for it though. Here are some pics to show what I'm talking about. In this picture, you want the port to be 35-3/8" long, so that's what you sized your port panels for. However the port ends exactly one port width away from side panel, this effectively lengthens the port. The port length you actually end up with is about 38-1/2". I never thought about port length like this, but imma screenshot that. Nice little tool to get that extra length, wonder if the miss notices those extra 3 inches 😅😂 SMD Tool Map (2022): https://www.stevemeadedesigns.com/board/topic/220267-smd-tool-map-2022/ My Port Size Calculator (in progress): https://www.stevemeadedesigns.com/board/topic/217087-port-size-calculator-in-progress/ Common Port Walls for a Slot Port: https://www.stevemeadedesigns.com/board/topic/217076-common-port-walls-why-it-matters-to-your-box/?tab=comments#comment-3240313 Link to comment Share on other sites More sharing options...

Other than that, it’s probably dope as fugh. But I tried to use it on a big ass amp on 2 12” subwoofers in an enclosure about 15% bigger than recommended. It was more like 2000 rms per cube, that’s why it didn’t work for me. But triticum hates me now because of that. Lol! Fugh it though. I can’t win everybody over.
