superchargedamd Posted August 16, 2010 Author Report Share Posted August 16, 2010 yeeeeep, when i was 12 i thought i knew how to build a box so i cut out 4 round holes and called them aero ports actually it didnt sound that bad but following up with what kranny said is you have alot of woofers. and pretty decent woofers too. spend some time and make a port. will sound and look alot better, also you will increase teh dbz what do you have for power on those things? electrical? power is a power acustick 5500d @ 1 ohm 3200rms,3 700 crank batts,40 farid cap and stock alt.yes i know the port sucks but torrets didnt say anything about depth.and it really seems to look like steves box no?

Steve's port is shallow compared to most, but not that shallow and the port itself is massive (WxH). You need to extend it as others have said and make it much larger. Don't sweat the screwup, post up what the box is braced with, how thick the mdf is, and the displacement of those subs and people can give you better suggestions. I've seen worse, there is a guy on here who just cut a random hole in his box. At least you tried to tune it Edited August 16, 2010 by UnderLoK Quote If at first you do not succeed, you are doing it wrong! -ARSCheck out my walled TBSS build over here4 Fi Team 18s on 2 Cactus K9 DS18 doors on 2 MBQ 1Ks, Vifa pillars on a STL4.500 Pioneer X8500 6 XS Power D7500, 1 3400S Second Skin 2 270a Mechman Alts Link to comment Share on other sites More sharing options...

I've seen worse, there is a guy on here who just cut a random hole in his box. At least you tried to tune it the box is .75 mdf,the sub displacement is .22each and there are 4 24 inch 2x4s and 6 14 inch 2x3s and the corners are about 3 inch at the widest part @24 long.i tried torrets again but when ever i add lenght the hz go down way low.at work i have cardbord tubes that range from 2.5-6 inchx.25 thick that would work great for a port if i know what to do with it.

UnderLoK Posted August 17, 2010 Report Share Posted August 17, 2010 (edited) i tried torrets again but when ever i add lenght the hz go down way low. As you make the opening bigger it will raise the frequency and as you add port depth it will decrease it.

Blue Posted August 17, 2010 Report Share Posted August 17, 2010 Uh, even though its just a hole in the box, it still has a tuning btw. What do you think regular ported boxes are? They are boxes with holes that happen to have wood to help direct air flow. Using the12volts.com calculator with a port being 10x10 with approximately 25 cubes of space (after all displacements) I get a port length of .5". He is using 3/4" mdf, so in actuality his tuning is probably lower. Now if he was to use a bigger port opening then he would need some wood to create a longer port. If you don't believe me, go to www.the12volt.com and put the dimensions that I used and you will see for your self. Quote formerly known as Blue86f150 its a 4th order just because its tuned in the 40z doesnt mean it wont reach down and jiggle your balls at sub 30 hz frequencies. Regardless if they were dipped platinum and were stuffed in Beyonce's twat.....way too fucking exspensive this sux camel dicks Link to comment Share on other sites More sharing options...

superchargedamd Posted April 8, 2011 Author Report Share Posted April 8, 2011 Your "port" is just a hole in your box. With a "port" like that you just have a leaky sealed box. This... you have no port, just a hole....seriosly dude you need to caculate a port to tune your box, it WILL sound 100 times better. with no port your subs have pretty much no dampning what so ever, as said you just have a big leaky sealed box from the dimensions you have you have a 32 cube box. you port area is way way way to small for you box a port 10x20 and 7" deep will tune you to 30hz and you box will sound a million times better, other than that nice subs and you did a good job on the rest of the box So after a long winter i am back on the system.I have went with 8.5x24x9 deep.Thanks for all the input.Just wondering what kind of lose the sub beating over half the port.I will be making the hole bigger to fit port then brace as ness.Thanks Quote Jensen head unit (junk to start) cadence 5.25 dash re tweets Candence ultra drive amp(mids+highs) rockford fosgate 75hd RESX18D2 X4 subs wired to 1.3 final REBUILDING AS WE SPEAK Link to comment Share on other sites More sharing options...
