jocko_nc Posted March 30, 2007 Author Share Posted March 30, 2007 Internal volume is right at 2.00 ft^3. Quote Link to comment Share on other sites More sharing options...
DrWho Posted March 30, 2007 Share Posted March 30, 2007 Nevermind then [] Btw, I thought flaring made the effective length longer? Or rather...the tube could be shorter for the same length when flared. I wonder how exactly WinISD identifies the port length...it's never really bothered me because a few Hz here and there isn't gonna change much and you would have to use measurements anyway if you wanted to really tweak things in.

jocko_nc Posted March 30, 2007 Author Share Posted March 30, 2007 There is a claculator at Precision Ports website. I think I recall the taper part does not count. ???. The taper certainly does allow for greater air velocity without disturbance or noise. I can attest to that fact. jocko Quote Link to comment Share on other sites More sharing options...

jocko_nc Posted March 30, 2007 Author Share Posted March 30, 2007 That's them. Parts Express sells their stuff, too. Note: The PE kits only go to 11.00 inches. ???. I bought another center section and an additional connector from somewhere. Quote Link to comment Share on other sites More sharing options...

jocko_nc Posted April 1, 2007 Author Share Posted April 1, 2007 According to the calculations, here is how it came out. V = 1.95 ft^3 Effective port length is 12.50 in. Tuned to 25Hz. I'm sure it will work, it similar to what I have been using for over a year. Last time it was more like 22Hz. ???. No goofy plate amp stuffed in the back. jocko Quote Link to comment Share on other sites More sharing options...
