mike-g Posted October 31, 2015 Report Posted October 31, 2015 Box is 1.5cuft airspace port is 2" w*12" h*26"L.how do I figure tunning?I read the post on ports but don't understand the equation. Can someone break it down for me please and thank you.
MotorCityFats13 Posted October 31, 2015 Report Posted October 31, 2015 plugging different values into torres calc.... if the 1.5cuft net is without port volume it is a 51.54hz tune if it does not include port volume then port volume is 0.69cuft added for a gross of 2.19cuft and a tuning of 37.87 neither of these figures include speaker displacement which in turn will raise the tuning a tad .... with a .15cuft displacement 12" the values would be around 40hz and 57hz.... I do not know the math to figuring out these equations just the programs that do it for you.... i would guess that the box you question about is the 40hz enclosure
Broke_Audio_Addict Posted October 31, 2015 Report Posted October 31, 2015 About 38hz is what I come up with. That's guessing on the displacements you have but either way it's in the ballpark. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
mike-g Posted October 31, 2015 Author Report Posted October 31, 2015 Thank you,that's what the guy said 40hz.I got for 5$ so figured I'd play with it
