vetkilr01 Posted December 5, 2013 Report Share Posted December 5, 2013 How would you go about figuring out what the sealed and ported sides are tuned to? Would the sealed side have to be open to atmosphere(sealed side closed, but ported side not closed and sealed) to get tuning...then closed off into ported section (so the whole box is completed) then rerun test and get the ported side tuning?

Kyblack76 Posted December 6, 2013 Report Share Posted December 6, 2013 (edited) The tool shows you WHERE you are.... What space are you using? what subs? volume? power? it cant show you where to be.... lol..... Your install will pull different ...

RooTxBeeR Posted December 6, 2013 Report Share Posted December 6, 2013 Now that you say, thinking about how you would use a tool like that with that type of box. How would it work lmao.

SPLadd1ct Posted December 6, 2013 Report Share Posted December 6, 2013 Easy peasy bro, I test mine all the time with different subs. To test the tuning (sealed resonance) of the sealed section, just take off your front baffle (if removable like mine is) so that there is no loading whatsoever on the subs forward wave. Your highest impedance will be your sealed resonance. To find the tuning of the port just find the lowest impedance between the two peaks in impedance; same exact concept as finding your tuning in a standard ported enclosure.

corona_jeff Posted December 12, 2013 Report Share Posted December 12, 2013 The way I do it, build the shell and seal it off, build sealed side, test for sealed Rez, tune loading wall to said Rez.......done Quote Link to comment Share on other sites More sharing options...
vetkilr01 Posted December 12, 2013 Author Report Share Posted December 12, 2013 Thankx guys...Definitely going to get one soon and try some things with it. Quote Link to comment Share on other sites More sharing options...
vetkilr01 Posted November 1, 2014 Author Report Share Posted November 1, 2014 (edited) So finally got around to doing some testing with the im-sg. Here are my results for seeing how my boxes useable bandwidth is: The Fl came out 44hz at around 6.5ohms The Fh came out to 63,5hz at around 8ohms and the Fb came out to 50hz at around 3.2 ohms. My useable bandwidth is 44-63hz if I did this correctly. So is this telling me my ported side is tuned to 50hz or 44hz ??? Thanks for the help.
