SOURCE: Need to build a ported sub box for my alpine swr-1222d subs x 2
Try going to Alpine web site, I think they have box building program as well that you just input your sub models into and it gives you blueprints for various types of enclosures. I know Rockford has one and a comparative attachment to compare equipt specs. Or if you call Alpine headquarters you may be able to get info that way, I once sweet talked a rep @ a demo vehicle I met doing some car shows that turned me on to a senior rep @ Korbon Trading the owners of Rockford Fosgate and they gave me specs for a 5 stage band pass box for some competition subs that was more intricate and detailed than anyone before that could find me, Won me first place in spl. Matching your box specs to your subs is crucial and the best specs are often kept a secret for demo competition vehicles! So ask around with some competition guys or other top experts if your real serious about your boooom.
SOURCE: need specs on a ported box for 1 12"stroker 124
I used to be a Cerwin Vega dealer. How much space do you have? Ideally you would want at least 4 cubic feet per sub. If you shoot me an E-mail @ [email protected] I will be willing to discuss exact plans for your application. I now run a local business designing custom enclosures and electronics for home, marine, and auto. As for your Stroker- A general box design is going to need to be ported with alot of volume (cubic feet) the bigger the better. The actual port diameter and length will be determined after I have some basics from you. I will give you a free design to start with if you Email me the specifics like how much room do you have? how much power? dual 4ohm coils? car, p/u truck, van/suv? The more info the better. If you want something more custom please specify and I will be happy to help.
SOURCE: building a box, need to know best dimensions for box and port
Hello dirt_digger6,
The specific sub you are asking about would seem to be the TS-302F which is the only 12" 800W Pioneer I have located.
Directly from Pioneer's support knowledgebase:
TS-W302F = Ported: 2.5 Cu.Ft. F3 = 39HzPort: 4 x 6.5 tuned @ 37 Hz with 12 % port noise.
An enclosure 16X18X21, constructed from 3/4" MDF will yield 2.69 Cu.Ft., allowing .19 Cu.Ft. displacement for the sub and port.
There's an excellent "box calculator" located here on the12v.com web site. You can measure the space you have to put the box and fiddle with the dimensions to get close to your ideal volume. There are also calculators on the12v.com which will allow you to calculate a port length based on port diameter (or width/height), enclosure volume, and desired tuning frequency.
Hope this helps.
SOURCE: Specs for Ported Box for 2 12" MA AUDIO HK12X2 Subs
Hello joseph_delac,
MA Audio's website has the recommended box volume and port size online here. A ported enclosure needs 3.0 CuFt of internal volume and the port should be 48 sq/in and 14.5" in length. A 4X12" rectangular port would give you the recommended 48 sq/in. Using 3/4" MDF, a box 16X18X25 has an internal volume of 3.25 CuFt allowing .25 CuFt for the sub and port displacement.
Hope this helps.
