stuffing in subwoofer box to make it hit harder?

Question

i made my own sub box, out of partial board. before i had it empty wit 2 12"s in it. and now i put stuffing in it with the subs, and now it seems like it is hitting alot softer? does putting stuffing in the box help or should i take it out to make it it harder?

Answer 1

Stuffing a sealed subwoofer box with dampening material can make the subwoofer work as if it's in a slightly larger box. This may or may not be desirable, depending on how well the subwoofer is matched with the box in the first place. It is not a substitute for a correctly-sized box.

Answer 2

Box size/design are what makes or breaks a sub.
You could take the best sub on the market and put it in a crappy box, it'll sound like crap. On the other hand, you could take a crap sub and put it in a box recommended by the sub manufacturer and it'll slam like h*ll.

My opinion, find your sub manufacturers' recommended box dimensions' and build a new box based on those.

Make sure it is COMPLETELY airtight. A perfectly built box with even a pinhole in it will make it sound horrible.

Polyfil, the 'stuffing' your all talking about actually makes the sub 'think' it's in a bigger box.

Good Luck!

It depends on what kind of subs you have. Check out the manufacturer's website. The will give you an optimal range of volume per sub. You want to be in that range, if you go outside of that range your subs will not perform as well. My guess is by putting the stuffing in your box you dropped below the minimum recommended volume for your subs.

Another thing to check is make sure your box is sealed air tight - especially since you did it yourself. Some caulk around the seams of the box on the inside will help. A simple way to test for any major leaks is to push on the cone of one of the speakerss (GENTLY) as one speaker goes in the other should come out if you have a tight seal.

Your fist mistake was to make a ported enclosure. Second mistake to make it very large. The boomy sound you hear is from the frequencies that linger and grow inside the box. Ported boxes, compared to sealed ones, sound louder because of only one frequency that they play louder than all others. Ported boxes were designed before modern amps that have this feature called bass boost. You can select the frequency you want to boost and set how much of extra volume you want on that frequency. The difference between 32 and 38 hz. is minor. Anything under 40 hz is simply hard to hear. You have to understand that your sub will not play this frequency until music contains the note with that frequency. Only then, this note will play louder than all others. Changing from 32 to 38 will not change the boom, it will only change the pitch of the boom to a bit higher. Your boom comes from waves that grow in size and linger in the box. Find the largest recommended volume for sealed enclosure and build your box for that volume. Also stay away from building all symmetrical enclosures. Either slant the back wall or move the driver 1/3 to one of the enclosure. Also, check the manual for your sub if it says that it is built for sealed enclosures or not. Ported enclosures do not put as much stress on the cone as do sealed enclosures. Stiffer cones is one of the reasons sealed enclosures sound tighter and cleaner. There are no extra waves from the deformed cones. Your sub is 8 ohms. The amp is producing only 350 rms watts at this load, which is lower than what your sub needs. To really fine tune your system, you need a quality equalizer. With it you can remove or add more volume to different frequencies. And you need LPF (low pass filter ) and HPF (high pass filter) to limit higher frequency from coming into your sub. It's not made for highs and they come out distorted. You need to really isolate what frequencies go to that sub. With the filters and the eq, you will find that perfect setting that resonates with your room acoustics and give you that rumble you want. You have a lot to consider and probably do your project over again. But this where the fun is, when you find what works best for you through experimentation. Stay patient and stubborn.

check your dementions, for every 10 inch sub you need at least 1 cubic foot of air space. well hopefully this helps you, when i install systems i do it mostly by ear and then by the book. what ever sounds the best for me is the way i go. now as far as "dampering your subs" well you should know what a damber does it absorbs sound and stops the reflection of sound from bouncing in every damn direction on the inside of your box. it also creates a double baffle which that is what your box alone is for and so to answer your question simply, you should take it out. alot of boxes you buy do not come with stuffing but a select few do. but again, whatever you think sounds the best to you. hope this helps you

Answer 6

Macaroni and cheese are always great but hey maybe you like a little sauce on it nothings wrong with that!!!! But you might gain a little weight but to answer your ? Dont stuff it it reduces sound quality and softens your bass

Answer 7

What you need is proper dimenions. You have to achieve the proprer cubic feet (volume) inside your box.

But I like Jessica R's answer better. (hot)

Answer 8

u should never put stuffing!
i ve never heard of ppl who do that
it muffles and softens the noise
if u are looking for a strong kick make sure u have the right dimensions not to big not to small, check out for any creeks were air might come out and put in a porthole as well
a porthole dramatically improves the sound
im also not sure about two woofers in one box

Answer 9

take the stuffing out stuffing belongs in a turkey are you cooking or messin around with an automobile please be more specific
