Sub sounds weird...

I removed my box and the sub from it, sanded down baffle and shit all level and flush so the sub would mount flush. Caulked all the seams up that were leaking air when the sub would hit and put the sub back into the box and the box back in the trunk. It hits much louder and tighter, but now it makes a weird sound it didn't before. Like it's hitting something or dare I saw, blown/bottoming out? It's not clean at all. Maybe something is vibrating hardcore with it in the trunk and makes it sound like the sub is doing it, or the box is taking more of a beating now that it's more sealed off. I can't figure it out? Is the sub truely damaged? Is that puncture in the surround (which I did find out went clean through the surround) affecting this sound? Help!

It could be bottoming out, but we need more info. What sub, how big is the box, and what kind of amp?

i think a puncture in the surround could make the sub sound like that.

Didn't someone say to rubber cement that up and it will work fine?...or am i just thinking crazy things again?

balls_to_the_wall:
People were telling me it wouldn't affect it, but maybe it is. I'll try that and see how it goes.

My setup is in my signature, look harder.

wow, all that trouble from a XXX, bet you just want that thing hooked up and sounding GREAT huh!. I'm not sure about that puncture disturbing sound that greatly, but you never know. see what SIN has to say lol

It could be unforseen rattles...clipping...shit like that. peace

Gain is around 1/4 to 1/3 of the way. I doubt it's clipping. All the bass boost is completely off as well. Ever hear a speaker when the cone is punctured/ripped or the surround is? That's how it sounds to me. From standing in front of it at the rear of the car it sounds just fine, but inside the car it makes that horrendous noise and sub doesn't carry notes like it did when I first installed it. It's actually installed RIGHT this time, but the sound is so different. I sealed all the leaks of air and the sub is sealed against the baffle properly and mounted securely. COULD a wire have come lose and I'm only playing on one coil? Is something damaged? Or is it just something with the box? I'm hoping it's something simple.

i've had rips n stuff in my older speakers/subs and they didn't sound that much different, but then again i didn't put a nail/screwdriver thru it lol

theres a chance now since u SEALED the sub in, the pressure is tearing the hole open again? since its probably the weakest part of the sub? im probably wrong, just a thought tho

Well, since the enclosure is a piece of shit to start with, I'd build a new enclosure with the right materials and make it match your sub and your ride. You need to take into account what your car's cabin is like and what the sub needs to run.

ur a dumbass his enclosure is not a piece of shit I designed it and he sent me pics of the final product just cuz it's not blingin doesn't mean its not a good box...... threed play it open the thrunk and see where the sound is commin from..... put your ear right up to the the sub and see if that's where its comming from.

good job defending your box^

good job defending your box^

Yeah, and I even performed the TRIPLE check for him....so the box is solid!

The box was done RIGHT. RIGHT materials, RIGHT measurements. I just didn't do clean cuts so not all the sides were flush. I fixed all that and it's perfect now. Just a new noise is coming out of it. I'm about to shower and I'll go outside and check it out.

WTF??? It has to be a cheesy box if he had unclean cuts and had to "sanded down baffle and shit all level and flush so the sub would mount flush". That means that before he had to have air leaks and other things going on. Yes, the hole in the surround doesn't help especially if it's a sealed box. If it is indeed the problem though, he should hear it with his ear next to it-he said he didn't.

It sounds to me like he's got the box all wrong. He says it sounds OK until he shuts the trunk and everything up.

I didn't look up this sub. If it's DVC, do you have them hooked up right? What about the controls on the amp? Did you have to mess with that when you took the shit out and mess with it?

if you can play the sub on a Baffle (just grab a 4x8 sheet of wood, brace it, and mound it in the center). play ad different volumes and see if it is the sub for sure. i it isnt the sub its probably the extra pressure causing the walls to flex/vibrate. if you determine 100% that it is the enclosre just build the same deisgn with thicker wood.
im not saying it was a bad design, but from what you said on sound illusions it is 5/8 MDF? if it really is it is probably the enclosure. build it with 3/4 and double up on the wall the sub is mounted on.

It has a double baffle.

To poncho, the construction is good, and with the problems with the box FIXED, the only other problem could be flexing. But I figured out it was some settings on the amp. But I still bet some flexing is going on with the box.

At 5/8" thick, I'll guarentee it is.

I would have to say it is a bad design also if it didnt fit flush in the first place. Was this box homebuilt or did you buy it? Was it built with plywood? If so throw it away and rebuild.

If I went 1" MDF and it rid me of the flexing, how much better/louder would the sub sound? I did some calculations on BCAE site and the box came out to be like 4.8^3 net. That's way too big. I plan on rebuilding Monday when I get some 1" MDF.

The current box is 5/8" MDF and sounds like shiat. My friends Kove 12" sounds a hell of a lot better then my sub.

It's the box then. Remember for ported enclosures...you pick a desired NET volume...then you must add port displacement and driver displacement to that. Hit me up if you need anything. peace
