What is my tuning frequency?

[Slammed 5,000+ posts]

DONT USE THIS NUMBER
But I threw some numbers together on WinSid and got 2.39 NET at 34hz with one of the port walls being a side wall for the box.

thanks for your help

thats pretty small for a 15" enclosure //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

port located on the front (right side) of the subwoofer
a typical slot vent

Not to thread jack...but I've wondered myself...On an enclosure with a top depth and bottom depth, don't you add the top and bottom and divide by 2? After that do you displace 1.5" for the wood or 3" due it being the top and the bottom?

Making some assumptions about your box design, I'm getting 2.55 Net volume with a tuning frequency of 35.1 Hz

Is the port on the slant or flat side?

Is the front angled or the rear? Does the port bend?

I got 2.6 tuned to 34hz. The port design is pretty terrible though. When I draw it up, your port panel touches the back wall at the top. This is really constricting to the port and I wouldn't be surprised if it caused some port noise at high volumes around tuning. Tuning might also be significantly lower due to this and because of how skinny it is vs how tall it is.

You can measure the tuning frequency with tones if you really want to know. Play some tones from 25hz to 40hz and watch for when the cone moves the least. This will roughly be the tuning frequency.

thank you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

2.6 is too small for a 15" sub though
