Hey I found a website that builds boxes to the subs specs its klausaudio.com. I got all the specs from my subs manual but what should my box be tuned to? My sub is a jl 12w6v2. It asks for the slot port tune and the square inches of the port area. What is the square inches of port area and how do you figure that out?
I have all the specs in the maual but it does not say what your box should be tuned to. It gives you dimensions for a sealed and ported but not the tune for the ported. What do you meen wut size box am i getting? Its for a single 12 and after i let that website no how to tune the box they will give me a price and dimensions of my box.
Well, the manual for the 12w6v2 suggests a 1.5 cu. ft. ported enclosure with the port area (slot width x slot height) of 18.75 sq. in. (1.5" x 12.5") and a length of 29". Now, just using those numbers I'm getting a tuning of 33.15 Hz for the port.
Huh? How do you get the tuning of a box with the port dimensions? This stuff confuses me but if its tuned to 33hz wouldnt i be missing out on some low bass or would it be so low that i wouldnt even be able to hear it?
The W6v2 works very well ported, still retains great SQ. 32-33hz is a good all around frequency for a balance of depth and punchiness, you won't lose a lot of low end, 20hz is what newborn infants can hear, the average human can only really hear to around 25hz, at least until the volume is raised to a super high level.
Sorry I didn't respond TWiZTiD, my internet's been down most of the weekend. If you have the space in your car, then go ported. You'll get better SPL. Average human can hear 20Hz bass notes. If you want proof, get a signal generator and set it to 20Hz. On most decent stereo systems, you will hear it. As you age, like 60+, you tend to lose that ability and hear maybe 35Hz, and also lose out on the high side, 12kHz. Something interesting, mouse can't hear sounds below 900Hz! Elephants somehow can hear 1Hz bass.
I heard 25hz as a roundabout for most adults (not sure about exact age), of course every source will say differently about it. I can hear down to 20, but I just can't speak for everyone since I don't have their ears, know what I mean?
Hey mo go to www.klausaudio.com type in the info they ask for and it will tell you wut it should be tuned to. Im guessing it will be around 32hz-33hz somewhere around there.That site is pretty cool they will make you any kind of box made by the subs specs,they also look pretty nice from the pics on there and not a bad price either.
I would set infra/sub sonic to 20Hz - 25Hz. If you listen to mostly rap/pop etc, 25 would do. They usually don't contain much deep low bass. MO, before you go blasing your JL 1000/1 amp, try a little sound frequency test. See if you can hear 20Hz and 20KHz. If you can, you might want to protect your ears. Excessive loud pounding such as SPL setup, will gradually lessen your hearing senses.
