Box size question

[dangaranga]

Hello guys,

I am building a ported box for my Pioneer TS-3002D4, and i am wondering if you guys think that a 2.2 Cu ft gross box tuned to 34-35hz is too big? and the net size is about 2-2.1 after port displacement. And i do in fact know that pioneer says max size of 1.6 cu ft ported

And here is a link to the sub i am using http://www.sonicelectronix.com/item_16665_Pioneer-TS-W3002D4.html

And thanks for your time and help

How much power are you throwing at it

Idd just do 1.6net with 2x 3" aero and enjoy

so your port takes up 0.1 cubes? dang

Post max dims for a box, vehicle and amp models, and music type/goals you have.

It's gonna be on 800-900 watts and i have a 3''x5'' aero port in the mail, and i also already built the box it's 24x17x12 but it's just sealed for now until the port comes in, oh and i made a mistake on port displacement lol the port displacement is about 0.02 cu ft. And it's going in my ex cab ranger

Also i want to be able to hit the lows decent, i don't expect anything insanely loud and I have a cheap 12 in the box on about 400 watts to just test it sealed and it does alright playing decaf, I just wanted some input before i go and start hacking up the box putting in ports

Thanks for your time!!

24x17x21 in 3/4 all round is 2.12gross after sub dis your 2

now you have 3"x5" aero port? thats going be tuned to around 40hz if its just 1off 3" port 5" long

the min idd want is a single 4" x12" long psp port in you want sub and port on front of box (at 35.5hz)

or side port it at 17" for 31hz

if you side port it youll get 33hz if you install 2x3" at there full 17" in length (the way they come from psp including the flare)

^this is my recommendation it will lower the net of you box a bit and give about 7.5:1 port ratio, it a bit low but will work ok

http://www.amazon.com/Precision-Port-Inch-Flared-Tube/dp/B0002ZPR4W/ref=pd_sim_e_2

if you want to hear the 'lows' (decaf or similar) you'll need to tune it lower then 40hz

if moneys tight just get the single 4"(not the best option but better then a single 3")

if not get the the 2x 3" (still not the best, but for your box as it is, is the better option"

if you want an spl type enclosure side port it with a single 6" at 17" long at 44-45hz

I am hoping to be able to play low but i dont really want to lose a ton of higher end output

Will this port you linked be able to achieve this? http://www.amazon.com/Precision-Port-Inch-Flared-Tube/dp/B0002ZPR56/ref=sr_1_1?ie=UTF8&qid=1372853430&sr=8-1&keywords=port+precision+4%22

And i appreciate the help i am just a complete noob at the whole box tuning aspect

Okay after playing around with Winisd it looks like a 3x5 port will put me right 36 hz after displacements, and to get the 4'' port to 36hz tuning i will need it to be 9.88'' long, i dont know which way i should go with this, i already have ordered the 3x5 port, i guess i could try it and if it doesn't work out i can just order a larger port and i have another box to use while i wait for a new port

[john253a]

A 4" 12" including flare will be 35.5hz

So yes a 4" 10" long no flare(as winisd calculates)

Would be close to 36hz

The 3" port will work and give you that tune, you will just get port noise that's all

If you have the space to port it out the side spend the $27 and get the 2x 3"

If you cant side port it then go the 4" x12" long an port it on the face

[dangaranga]

Well i already ordered a cheap 3x5 like 3 days ago but it was only $3 if and when it doesn't work out i will order the 4'' port like you said i will make sure when i install the crappy port it is in a spot that i can just cut a bigger hole for the 4''. Thanks for your help

Will this be a over the backseat enclosure?
