[QUOTE="Buck, post: 8744529, member: 591582"] On the first pic, if you make a chamber like that, do it tapered down in some fashion. Don't have it hit a 90 degree wall when it shrinks down to the port width. I would angle the larger chamber into a smooth transition into the line. And that chamber will act as line length as well. Just think about a tapered t-line or a reverse horn, if you will. Going from bigger airspace to smaller airspace means you get lower tuning. So I would keep that in mind. It's hard to get exact tuning, there's so many factors, but it may help you get as close as you can without actual physics modeling software :unsure: [/QUOTE]
