best BOX

I have a nice sized sealed box for my subs. I was wondering, whats the loudest type? I have faced mine in every direction and find facing the trunk to be the best, but the trunk is gonna fall apart the way it gets hit.

Also, it seems that if the subs had a more solid surface to play against they would be louder. Would it be worth trying to do anything to the trunk?

Running:
two Kicker Comp VR 12" dvc wired for two-ohm stereo
audiobahn a8002t 400 rms x 2
1 farad capacitor

if you want to make it better, and don't want to k1ll the trunk. fire them forward but seal it off from the trunk area all together.

Sounds and feels weak facing forward. Trunkspace deepens the hit I think.

Read what I said.. You must seal it off completely from the rear of the trunk for it to work.

he's talking about building a wall...i do believe. walls are good sometimes and bad sometimes, all depends on your setup. if you don't want to blow apart your trunk then turn down the gains on the amp, you are going to lose volume but gain SQ and save your trunk

Call this a crazy idea, but I have thought about making a plexiglass wall right near the trunk for them to play off of.

It depends on what kind of music you listen to and what style of bass you want. Ported boxes are louder at a certain frequency, but above and below that tuned frequency, the volume is much less. Sealed boxes hit a broader range with less difference in volume. Bandpass is a mix of the two. The reason the bass sounds quieter when they are pointing at you is because the bass waves have not had time to fully form before they hit your ears. When they face backwards, they have time to form by "rolling" around the box and forward to your ears.

Its the mid range of hits, in rock music and Im getting some dynomat to help with it.

btw... that was a great answer. thanks

any thing I want to know before installing dynomat?

if it is true "Dynamat", the surface does not have to be spotless or prepped at all. This stuff will stick to anything. The more surface area you cover, the better your system will sound. Not only will it reduce or eliminate rattles that you hear, it keeps the sound waves in the aubible form. I'll try to explain. When things in your car rattle, vibrate and shake due to bass waves, that is energy in the form of pressurized air. If you can eliminate shaking and vibrating, the energy does not transform into vibrations and it stays in the form of what you hear. So, at any given decibel level, if you have no sound damping material, it will not be as loud as your car will with damping material. Make sense?

A whole lot of sense. Its not a flat surface either, the trunk has a kind of framing to it with openings. Im just going to cover the whole thing, that should k1ll the hits before they hit the outermost surfaces. Thanks man

just get the dynamat on as much as possible. Go to your local home improvement store and buy a little roller for wallpaper. It's about 1" wide, made of wood usually. This thing works much better than your hand. Also, you can use a heat gun and a GLOVED hand to cram and push the dynamat into the dips and valleys. You want as much contact as possible.

Don't know were I'd be w/o td.com thanks again. The heat gun is to help stretch it in right?

this is easier and better than dynamat, order either some of the paintable stuff or the mat material http://www.edesignaudio.com/edead.htm

Thanks man.. I am already waiting for a friend to bring me a roll of dynomat. Thats a nice site though.

That might work in my Astro Van

i guess I will add my .02, although wndotint gave a bunch of info, here is more.

Ported box, the bass travels father and you get move of the sound wave. you get sound from both sides of teh cone. the port tunes a certain frequency to meet in sync outside the box and in short you get double the wave and thus sounders lounder. But beacsue of teh port the cone travels a farther disctance in each direction, thus makeing reactoin time less and the bas not as accurate.

Sealed boxes when built to spec, create a tight accurate bass. the cone doesn't travle as far because of the pressure created inside the box. this gives the cone a tigher reaction time, thus createing more accurate bass notes. All the notes will be in the same volume cause of the sound coming off one side of the cone.


Band pass: I don't like thus I will not talk about.

And as wndotint said, bass sound better when reflecting off the body of the vehicle. bass notes are long, (reason that bass in its pure form is non directional. the note enters both ears at the same time) and allowing the note to reflect gives the wave ample time to mature.
Even notice that some systems sound much louder outside the car? those long bass notes matured well!

note: if building a box, is is great to brace the box on the inside, this reduces box flex during high volume and big notes, and also eliminates standing waves inside the box, that otherwise might not exit the box good. brace with different size triangle shaped on the sides, not he front or back.

tired from this post

Thanks so much NB, that was a hell of a lot of typin. Ive been saturated with info from this and its all been a lot of help. Im saving $$ for a while, I'd like to get one of the OEL disply Pioneer decks to improve it more.
Like NB said, the cheap deck has to go. One those "Get what ya pay for" stories.
Thanks

well like i siad b4, the sound starts at the head unit, so if u start wil junk , u will get junk no matter how good the rest of your system is.

oh and a neon is a respectalbe car to hook up, , i have an elantra

Alright NB! Not bad at all. I looked at a Elantra GT when I did some flat for a Hyundai dealer. I think my car's pretty fun to drive, and cheap to fix too. Glad I'm not the only one.

for me ive had all types of boxes on my car. Had this ported dual sub box, it sounded good but not like i wanted it to sound. Also had a sealed box, was good too.

The loudest and deepest bass pounding box ive ever heard is the Death Box. I made it with a friend of mine, got the instructions from this site here on the neet. I only got one 10 inch woofer and it pounds like crazy, the deepest and cleanest bass. All u need is one sub, either a ten or one twelve inch. I settled for a 10 inch Sony Xplode 1,100 watt woofer, but gonna get a jl audio soon.

if you want a huge SPL woofer let me know, i know the guy that owns elemtal designs and he is currently taking some of his old stock and makin it unbreakable basically. he also makes KILLER SQ woofers and awesome amps. check em out www.edesignaudio.com

BTW wtf is a death box...never heard of it and i'd stay away from JL unless you like paying out of your ass

i don't know about Death Box either but I am guess it is a local brand that uses a CNC machine to coputer cut boxes.

I had a V tech box, that kicked ass but I am sure it was not a national brand, they are out of business as we speak, but did have some killer boxes.

I am not fond of any prefab box, not uit to spec for any speaker. IMO.

yo naughti if you ever in the market for subs make sure you check out elemtal designs...they make JL and Resonant engineering look like pussies. They are more oriented toward sq subs BUT make some killer SPL subs if you are interested. he makes a 1 ohm stable and stackable. their new v.2 lines are just AWESOME to say the least, their components are more clear than cdt's...just no telling how good they sound and the price he has them is soooooo hot. check em out dude www.edesignaudio.com and they also have a forum at www.icixsound.com

not in the market now, but will be sure okeep them in mind when I am .

This is a death box. U might have seen them before.

I made the box myself, just got he measurements and all, sounds deep and good too.




As for JL, a good buddy owns a shop, gives discounts all the time when I need one.

looks liek band pass 2 me.

what i like about it is the adjustable port.

IMO any box built to spec sounds the best period point blank.

i,d build a custom box,at least two cubes seald.

two cubes? are you talking cubic feet, or 1x1x1 type of cube?

if u r talking cubic feet then, i would say that a box built to the specifacation of the indended speaker will souund better than anyother box. most quality speakers come with a spec for a sealed box (SQ) and a spec for a sealed box (SPL) so you can build a box to fit your taste best.

is you are talkign about dimension's than again I would say that the interior dimensions of a box makes no difference in the sound. two boxes with different shapes but same cubic dimensions will sond the same.

.02

what was the website called cos im trying to build some custom boxes for a competition. would really appreciate some advice

here the site bro. I didnt buy thier stuff but i had an idea how to make it. Are u trying to make it for a 10inch, 12inch, or 15inch.

ooops, here it is

Here is one decent ported box write-up that I found . It was for a box building contest being entered so he spiced up the writing of it a little I think .

if want all the bass you can thers one way to do it. you need to bulid a blow threw in the rear deck you be louder than any other way to do it . plus u wont get trunk radle.

I think he may have figured it out. This thread is four years old.
