    Re: hz??? newb question

    Hz is the frequency of the sound playing. Your question makes it seem your asking about box tuning however. In that case,

    Generally, SQ boxes are tuned lower than SPL boxes, and it's easier to hit a higher number at a higher frequency burp (50hz, etc) while it will make music sound pretty bad. Musical boxes are generally tuned from 28-40, with 30-35 being the most common.

    Re: hz??? newb question

    alright got it, i was going for more box tuning sorry

    but ya i'm going with a 15" L7 i should have by the 31st, so i'm saying it's sq is going to **** regardless, so i think ima tune around 38 hz.

    does that kinda make sense?

    Yeah that makes sense, but just because it's an L7 doesn't mean it won't sound decent. Sure, it's no RE XXX or anything, but it will still sound decent.

    Also, do you plan on hitting the meter or is it just for listening?

    I've found generally lower tuned boxes appear louder to the ear then a higher tuned box.

    ya im not saying it's going to sound like poop, but like you said, l7 vs. XXX haha good joke right?? i'm a huge XXX fan, i'm just going for more deep, sound pressure if you get what i'm saying

    but not for metering, and know what you're saying about lower tuned boxes, but they don't..... 'blow s hit up outside the car' as would a higher, deeper sub. just kinda what i'm going for, crazy i know lol, but i have a buddy with two 12" CVX's tuned to 35hz and the 750 amp, birthsheet 928, and it's nothing now, we can have a normal conversation in the front seats while people are quivering in the back, so i just want a little more, just enough for a noticeable difference. i want the sub to be able to be at a 'normal' lever, and be able to just keep turning it up

    haha quite a bit but that's what i'm going for so i think it'll be good??

    Then for what you seem to want your going to want to tune 35-40hz. I'm tuning my MT to 38hz or so. And yeah I know what you mean, try it at 38hz. Every car and sub combination will react differently, so no matter who comes in here and say whatever it's not going to be 100% accurate for your case.

    But your idea of 38hz is a very good start for what your going for, try it at 38. If you don't like it drop it to 35. Worst comes to worst you need to build a new box, no problem for me cause I find that **** fun.

    Let us know how it turns out in the end though, you'd be surprised how many people here ask questions then never come back with the true results.

    cool cool, so i think you see where i'm coming from and everything, and exactly if it doesn't work out, that's another fun expiremental project to work on ha

    but i'll definently keep you posted on how it goes, like i said it'll be around the 31st i'm getting everything

    one last question, where do you get your box calculations from??? i know RE has one, but i'm looking to do sub up, port back, 14" tall, 36" wide, and depth doesn't matter, i have room, but how can i figure out what the box is tuned to???

    thanks for all your help

    I use the RE Enclosure calculator to get my boxes tuned, they are off by like .3 on their calculations, but hell it's close enough. Subwoofertools used to be a great site, but it's been down for a couple weeks now.

    Sub/port placement doesn't matter, it'll have the same tuning regardless so you can use the RE calculator.

    Then if you want to model it up in 3D to get a feel for how it'll look and cuts and stuff you can use Google Sketchup.

    And NP, it's my duty to help Feel free to post or PM me or hit me through AIM for more help

    EDIT : sorry about the hour between my posts, I was eating dinner
