simple basic enclosure calculator for woofers ?

[zuki]

i tried the dpc program , but i don't have the knowledge to use it.

these are the woofer parameters

it is a car woofer

Usable Frequency Range: 20Hz – 1.2kHz • Recommended power amplifier range:18W – 400W • Continuous power handling: 300W • Voice coil diameter: 2.0” • Sensitivity (2.83 volt/1meter): 93dB • Impedance: 5 ohms • Thiele/Small Parameters • Free-air resonance (Fs): 28Hz • Total Damping (Qt): 0.43 • Equivalent volume of compliance (Vas): 10.42 cu.ft. • One-way linear excursion (Xmax): 0.3” • One-way excursion limit(Xsvs): 0.91” • Cone area (Sd): 140 sq. in. • Dimensions • Overall frame diameter: 15.1” (384mm) • Cut-out diameter: 13.6” (345mm) • Mounting Depth • Top mount: 6.6” (168mm) • Bottom mount: 7.2” (183mm

i wanted to know the port size and ported and sealed box size for it.

It depends on where you want to use it. In a car or in your house? Also if you can give the brand and the model, it can help us.

it is a JBL P-1500

that crutchfield used to sell long time ago.

it is a car sub.

i just wonder how it works on a box calculator.

thank you.

sorry for delay in response

 

[simon5]

Well box calculators like WinISD and Unibox can offer several recommended alignments depending on what kind of sound you want to have and where your subwoofer will be located, in a car or in a house. I'll try to help you soon, but now I must study for my exam.

i would prefer the most musically accurate box results vs. what type of sound might be prefered by the listner.


thank you.


i was hoping there was a web site where you could just plug the parameters in and hit the calculate button.

There is one online one I know of, winisd online. I think its the same as the program with less options

Heres the link, Hope it helps

WinISD online

😱 25 foot box for 2 woofers

 

[simon5]

Did you specify the Vas in cubic feet?

If you specified it in liters, the resulting box volume is in liters.

 

[zuki]

all the specs i used are in the first post up top ^

 

[richie00boy]

You got such a large box because Vas is fairly high and:

1. the Qts is just a little on the high side for a vented box
or
2. you tried to choose a low Qtc sealed box

it is a car audio woofer

i only entered the info that comes with the speaker.

the manual does not recommend a box of any size for the woofer.

What volume do you have available ?

A 25 cu. ft box is correct. This speaker can go real low, but it needs a lot of volume to do so. It can be made smaller tho, somewhere around 100 ltrs. If you use 2 in isobaric configuration you can half that volume. 65 ltr closed, fully stuffed (isobaric) would be nice enough for use in a car.

I tried the first woofer you talked about and I have a 6 cubic feet box. The second woofer you listed take even more space.

Tell us what do you want, we will help you to find a woofer.
Tried PartsExpress.com?

 

[zuki]

the jbl woofer works in a sealed or ported 6 foot box ?

it was cheap is why i liked it.

 

[simon5]

6 cubic foot sealed give a Qtc of 0.707 which is ok.
With ported you could go a bit lower.
It's a good woofer for bass over 30 Hz ported and over 40 Hz sealed, unless you use a horn.

What's your budget? I think there is maybe something better for the money.
