Subwoofer box dimensions

[kingludba]

anyone have an idea of the size of box to build for my 12 inch sub, dual voice coil jobbie, here are sum pics of it

[chu346]

Hows about you give us the T/S parameters of the sub, or atleast some kind of idea of what is is so we can find the specs.

If you can't be arsed to do that, just make a box 12"x12"x12"

Have you looked on the manufacturers website??

There's a chance that the recommended box dimensions are listed on there

12"cu is too small. you need about 1.2 to 1.5cuft. the bigger the box the bass would be deeper.

[miniblob]

I would go with 1.5cu ft, but as above, at least need a model number to search on, then you'll find a recommended size!!!
Also assuming you're knocking up a sealed box, not ported?

[kam325itouring]

the sub is by lightning audio i dont know if they are still around?

12"cu is too small. you need about 1.2 to 1.5cuft. the bigger the box the bass would be deeper.

I said 1cuft because he hasn't told us what the specs are or who its made by.

I put an atomic 15 in a 1cuft box and it sounded awesome. BTW I did make plenty of different boxs for the atomic ranging from 2.5cuft down to 1cuft sealed.

I someone gives me the specs, I can design a good ported box for this sub.

The sub really has no info on it except the logo sc on the cone and on the terminals behind the sub.
its heavy as feck so figured it must be able to pump!! thanks anyway, will try looking for the manufacturer again, can anyone recomend a good mono block amp that wont break my budget and should I use a power cap or is that for bigger systems

Thanks

just searched lightening audio on google and found my sub, 500 wrms, box size is 0.75 cu. feet, just need right amp now.

[chu346]

Forget the power cap. You'd be better off spending your money on making sure the charging system is up to the job. For this you need to upgrade your altenator, battery and engine earth wires.

You'll want to have a box about 1cuft because after displacement of your sub it will go down to the 0.75 that you need.

If you let me know the depth of the sub, and what rough shape you want I can reshape it and tell you what cuts you need from mdf.

A rough idea 15hx15wx8d

What is your budget for an amp? and the power/resistance of the coil(s)?

[kingludba]

Size 12"
Impedance Dual 4-Ohm
Power Handling 500 Watts RMS
1500 Watts Max
Motor Size 160 oz.
Voice Coil 3" 4-Layer
Speaker Connector Compression Terminal
Mounting Depth 6-1/16"
(154mm)

does that help? not worried about design of box, square is fine but I like my bass very deep! sealed would suit more for deep wouldnt it?

[kingludba]

also, this is the amp I had in mind....

I wouldn't buy new, I get all my stuff from ebay and never had a problem.

how do I wire up the sub for best sound, it gt dual voice coils

[chu346]

What amp do you have and what power does it do at each resistance???

Once you've worked that out you can pic one of these way to wire up your sub. http://mobile.jlaudio.com/support_pages.php?page_id=161
