Ive been reading a lot of subwoofer enclosures and people are saying their tunning their boxes to 33?
Continued——-or 37 Hz and i know thats hertz but i don’t understand what they mean by tunning it? Or what hertz is, Thanks to all that help.
For ported enclosures the enclosure will be "tuned" to a certain frequency. The tuning frequency used will determine how the sub will perform as well as a few other factors.
Typically, an enclosure tuned higher like at 37Hz will be designed more for loudness and SPL. You will typically lose sound quality to gain output. To gain sound quality you will typically tune the enclosure lower. 33Hz is typically a frequency that will give a good mix of sound quality and output. This is all general as every sub will be different. All subs will have different tuning frequencies that they will perform the best at.
The actually frequency a ported enclosure is tuned to depends on several factors. These are a) the internal volume of the enclosure (not including the port or sub displacement) b) the cross sectional area of the port (height x width of port) and c) the length of the port. If you know all of these factors you can determine what the tuning frequency is.
Actually designing a ported enclosure is a bit more involved then just figuring out the size of the port you need to get a certain tuning frequency. You need to take into account other factors such as what cross sectional area you need to not have port noise. You also need to make sure the port is not too long that it is not practical for your application.
Good Luck!!!

33 or 37 hz is a tone, or a sound frequency at a certain pitch.
tones in the 30s hz area is very close to the edge of a normal human’s hearing range, which is 20 hz. (the upper limit is 20khz)
Tuning is mostly for ported enclosures, making the port a certain length and diameter.
This allows a certain frequency to vibrate the most as it comes out the box.
Tuning a box to a frequency as low as 33hz, has alot of potential to really shake a vehicle.
