Sub Box

Allright, im pretty new tothe audio part of my car and now that i have pretty much done what i wanted cosmetic to my car, i want to put a system in it, i have everything ready to be set up, but i want to build my own sub box. now i have a 15" sub and i need to know what kind of specs i should build the box to. i have found alot on he net about 10's and 12's but cant find anything on 15's... shoul i go ported or sealed? how much air space would i need? should i do a fiberglass mold (dont want to because too time consuming) any help would be greatly appreciated.

Re: Sub Box

well first, what sub is it?
second, what car do you have?
third, how much power do you have?

Re: Sub Box

hm, well it's really hard without the specs of the sub to go by, makes it impossible to model up how it would perform. I'd say a good guess would be 3cf tuned to ~33hz for ported, or maybe 2cf sealed

Re: Sub Box

Well here's their website...

http://www.legacycaraudio.com/index.asp

The 'woofers' sections seems to be down... Chances are they wont even list T/S parameters on the site.

Re: Sub Box

i think id go with around 2 cu ft sealed.. just because you need to be more exact when it comes to ported boxes and i think guessing for a port size and box size may do more damage than good. 2 cubes sealed is a good average size to go with, especially if the 1400 watts is the max rating, which im assuming it is. Plus, sealed boxes seem to be a littl emore forgiving in general, which may be very helpful in your case where you dont know any TS parameters

Re: Sub Box

I agree, sealed is definitely more forgiving, and it's probably the best way to go when you don't know any of the specs of the sub.

Re: Sub Box

Just wondering? Why this sub? If you can afford to make your own box?

hehe, we don't know the T/S parameters for the sub, 2cf was just a completely wild guess, do you think it really makes a difference whether that 2cf is before or after sub displacement?

make it out of 3/4" mdf
