I need recommended factory specs for this 10 inch Sub woofer (I am building my own box)

air space behind the cones of a speaker is critical to the performance of the speaker. the space behind has to be air tight. If the specs state a minimum of 1.25 cu ft and a max of 1.75 cu f t that is what you will have to achieve for the performance If you build a box for 1.75 cu ft then when the speakers are fitted you will probably spot on. Go on line for speaker box construction and you will get valuable info. for your project

yeah, you likely cant build a box to tune 35hz... try just building a box that has correct spec by the manufacture for ideal operation, and adjust the gain accordingly, that's where you will attain your desired hertz, oh and by the way hertz refers to signal, and pulse rate,

the box is 5.75 cubic feet

basically its length x width x depth in feet

If your looking to build a box yourself, build it as big as you can, and still be able to fit in your vehicle. Same goes if your buying one. There are no certain specs for a sub box as long as the speaker fits. The bigger the box the more bass. ( Up to the speakers capabilities )

It depends on the size of the subs- 8z 10z 12z 15z? whether or not you port the box is up to you- a ported box is generally louder than a sealed box -as you are coupling and tuning the sound from the rear of the driver with the sound generated from the front of the sub- but the box is also generally larger as well.Then aside from your preference of ported/sealed you have to account for the recommendations of the manufacturer as to whether the sub/speakers are meant to be placed in a ported or sealed enclosure. Most 10 inch subs do well in a box that yields .75 cubic feet to1.0 cubic feet.most 12z do well in 1.0 cu feet to 1.5 subic feet and 15z do well in 1.5 to 2.5 cubic feet. I have a set of 15z that require 4.25 cubic feet per sub-so its important to look into the manufacturers recommendations. The easiest box to make would be a sealed enclosure-and the sound quality generally yields a tighter more accurate bass sound along with increased power handling capability- try going to rockford fosgate .com and look into the woofer box wizard its a program that calculates air space for whatever size box you have room for-hope that helps you-good luck

do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

< I design sub enclosures for a living so you are in luck. > The one thing to remember is that generic sub boxes are just that - generic. Even if they have a fancy brand name, unless they are built for the sub you are using you will be making a guess as to how well it works. Don't get me wrong though it may work well in that band pass box, but just imagine how much better it could sound in a custom enclosure. Having said that you have the right idea, and bandpass enclosures can be power-full. If you send me ([email protected])
the specs that came with the sub I can give you an idea of what kind of box you should get or, if you want to build your own, I can do the specs on that too. Personally I stay away from bandpass enclosures for one reason. When the subs distorts or gets pushed too hard you can't hear it happening. Since the sub is completely enclosed it's somewhat muffled or insulated so that distortion is hard to hear, which can blow up subs. A good ported enclosure would do well and basic plans should be on Lanzar's website, or available from myself. I do not recommend a sealed enclosure unless these subs will see light duty and you don't expect ground shaking bass. They can sound okay in a sealed box but most car audio enthusiasts like the ported boxes for their increased output and lower tones. Email me if you can't find the specs on those subs I might still have them on file. (Also the enclosure should be at least 3/4" thick MDF with bracing throughout.)
