Hey I been thinking that I may need a new box for my Havoc. I just dont think the 2 4" aeros are enough for the sub. I was wondering if you had any ideas on a design that would work well with the sub. Slot ported this time. Probably around 4cft tuned to around 32hz. I have a x-cab S10 so space is somewhat limited. I have about 40" in wide,24" tall and around 15-16" deep to work with. Sub and port could face up or just sub up and port on the side. I dont really know. Do you have any suggestions or input?
What amp are you running? I didn't really see anything wrong with that box either.
Power you're using is important to determine exact specs I would use. I'm not sure what would be best for you- I've seen a lot of guys running sub forward port on passenger side and it sounded awesome. One of the loudest single 12 <1000 rms vehicles I've sat in was a box built in an extended cab s10 sub forward port side.
Double baffle, sides are counter sunk .25" each, this is 4ft net tuned to 32Hz with 50sq of port after all displacement figuring .2ft for the sub displacement since a quick search didn't turn up that info. You could make the port a bit larger if you wanted. Also using 2 2x4s for bracing on the face to the port, and one from top to bottom mid-box. Dims are 16d x 20h x 35w, port 20 x 2.5"
Im runnig a JBL BPX500.1 does 718wrms @ 4ohms. The box its in now is 4cb ft. with 2 4" aeros,sub forward/ports up. Its tuned around 36-37hz b/c the box was designed for a HD3. I was just wondering if you think the 2 4" aeros are enough port area for the sub. Im eventually going to tune lower if I keep the box I have now. The sub gets loud in this box but I didnt know if it had enough port area or not.
with two 4" aeros you have about 25sq inches of port area for a 4cu ft box...you do the math...for instance if you had a DD 15 in the same box you'd need a minimum of 60sq inches of port area for it to sound right....
