I need to know what the recommended box spec for a audio Bahn dJones special edition 15 woofer 500 watts is trying to build a box for it

Where do you want to put the box? What are the Thiele Small parameters for the drivers? What kind of music do you listen to? What kind of woodworking expertise do you have? I'll try to look up the factory specs for "Black Mombosa" 15 inch woofers (is this it? http://www.amazon.com/Q-POWER-BM15D4-Black-Magnet-Subwoofer/dp/B00C86R2VY), but still need answers to the other questions before I can even start to help.

• frequency response: 24-200 Hz
• power handling: 300-600 watts RMS (300 watts per coil)
• peak power: 1,800 watts
• sensitivity: 85 dB
• top-mount depth: 6-3/8"
• sealed box volume: 0.65-1.25 cu. ft.
• ported box volume: 1.0-2.0 cu. ft.
• Crutch field audio has a DIY section on box building ;)

are you sharing the air space or building a divider to give each driver its own air space

these speakers or not made for low end bass these woofer are meant for mid bass high bass

6.5'' High Power Subwoofer

Non-Press paper Cone

Specially Treated Foam Edge Suspension

1.5'' High Temperature Aluminum Voice Coil

Magnet Weight: 40 Oz

Impedance: 4 Ohm

Fs: 80Hz, Qms: 4.05, Qes: 1.3, Qts: 1.2, SPL: 87(dB), Vas: 6.8(Cuft)

Mounting Depth: 3"

Rubber magnet Boot Cover fers are

there is only 3 " of mounting depth needed i would build you door pannel out fiberglass a door pod and mount them on the door if you have a factory speaker there . then run to the amp and turn the x-over on to high pass and them use them as a mid bass driver up front for the front sound stage for get about them as a subwoofer get the lanzar 10's or 12's

i mounted a set of ma audio 8" subs on my 03 s-10 door the speaker fit in the 6.5 location had to trime the door metal and space them out a little cause the 4.75 mounting depth.it worked and then i ran the them in 2 ohm stereo to my 4 channel amp and used the high pass crossover to run them as a mid bass driver works great for me . ma audio 500 watt dual 4 ohms 8" subs each i had 250watts to each sub.

you could build a small enclosure just big enough to fit the 6.5 woofer you could build a dual camber enclosure like 8wx5dx8h internale air space would be 0.18

15 wx5dx8h would give you 0.347 share the air space this is internal air space

Hi,
I've had a look at the JLaudio website and they recommend 2 box designs, a ported and a sealed.
The sealed box needs a volume of:
2.125 ft3 or 60.2 litres.
To get this you would need to build the box to these dimensions:
22" x 16" x 14.75" or 559mm x 406mm x 375mm
The ported box needs a volume of:
3.50 ft3 or 99.1 litres.
To get this you would need to build the box to these dimensions:
24" x 19" x 18" or 610mm x 483mm x 457mm.
The port needs to be:
3.0" x 10.9" or 76mm x 277mm.
The enclosure recommendations listed above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.
• All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into acount.
• When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and, in the case of a ported enclosure, use three times the recommended port(s).
• We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.
As you can see it all depends on the space you have available, whilst the vented box will give you a more efficient bass responce especially with the low range frequencies.

If you to go and look at the information about your sub woofer and find out all the information about building or buying the correct enclosure then this is the link to the pdf file I found:
The enclosure info is on page 3:
JL AUDIO 15W3 Tech Specs and box info.
Warm regards

single shallow with a sealed box it would sound great!! no air tombs they **** thats called ported they really ****

Do yourself a favor do not get anything Pyramid they are cheap for a reason and you will not get good bass response from them even in a optimal enclosure.If you want nice bass for little money go with lanzar opti 1535D sub you can pick one up for around $265 and will blow away Pyramid any day.

they are so many ways to run a dvc sub, let me know what ohms the coils are, and i will give you the ultimate bass that will hurt your hearing.

yes bot if the woofer is 500 watt don't make to loud you will blow the woofer of.

try a box with smaller prts or go with 1 vented box

i need to know what the box dementions are for a 15 inch cerwin-vega subwoofer v max 1000 w peak power?
