Is there a way, besides through expensive trial and error, to determine cabin gain for subs?
Well, I'm trying to find out just how much my cabin is contributing to how my sub sounds. I have a t-line built by CSCStang, and am considering changing over to a ported enclosure, so the more knowledge, the better. I have a huge cabin...Ford Excursion. Based on some reading, I know it's going to be low, but just how low is the question. And I don't know if playing tones will help with a tuned box, would it? I mean, if the box is tuned to 38Hz, the box should tend to play that tone loudest. Unless I played them with the sub outside the truck and checked volume there then compared them all to being played inside the truck?Enclosure and the cabin's own acoustic environment is key. Maybe run some test tones for highest/loudest Hz. value. Obviously, the smaller the cabin area, the louder it will be.
What are you wanting to do/trying to accomplish?
Model and build a simple .7 Q sealed box and put it in the vehicle. Meter your response and plot it on a graph. Anything above/below predicted is likely your cabin.... bear in mind that moving the box around and changing aiming will change things a bit too.Is there a way, besides through expensive trial and error, to determine cabin gain for subs?
the REAL WAY to plot the cabins acoustic gain and resonance is pink noise and playing tones. to do that you first need to have a flat response with no cabin AKA free air.Is there a way, besides through expensive trial and error, to determine cabin gain for subs?
What ??? You actually worked on your stereo and no pics ? Or did I miss them ?t-line enclosure?! Funny, I just got done building one designed by him....and it's a 1st for me.
a tline for 2 15s is about 25 cubes. i doubt he could whip his ***. lolWhat ??? You actually worked on your stereo and no pics ? Or did I miss them ?
stfu and go work on your stupid prototype....you don't know wtf I'm even talking about.a tline for 2 15s is about 25 cubes. i doubt he could whip his ***. lol
no, not yet...in the middle of the build, kinda. Built enclosure for the single m3 8 I had sitting around.What ??? You actually worked on your stereo and no pics ? Or did I miss them ?
Perhaps this will help...since PB isn't working for me anymore. http://www.caraudioclassifieds.org/forum/general-car-audio-discussion-questions/253274-1st-t-line-enclosure-build.htmlOh ok . Can't wait to see it !
