yeah my bad.
so tell me jeeper07 wich one will it be a bad design that sounds good. a good design that sound bad. if it sounds good it was sure designed properly. if it sounds bad then ovously something whent wrong.

Well actually in my opinion a good design can sound horrid. A box tuned about 36 is ugly to me, but also port noise etc can make it sound like hell. On the contrary a poorly designed box can sound good, and just rob your sub of major output.

How about this. A well designed box and a well built box will sound good. A poorly designed box and a poorly built box will sound worse. Anyways, back to THIS box:

an enclosure tuned at 36Hz will see a cabing gain and freq responce drop as well because of the cabing gain. lower freqs will increase and extends, port noise should not be visible on this enclosure thats the reason the port looks the way it does.

so what are you saying?

I'll take pics and yall can judge if it sounds bad, where it went wrong. Design, or build. haha, this forum is awesome

The only reason i gave you money is cause you sounded like you knew what u were talkin about, so i trusted you. And now your able to back yourself and i still trust this box. Plus, your debating with a bunch of 16-19 year olds for the most part anyways.

im really not debating on this thread. just trying to help them understand the enclosure. nothing more nothing less.

Thanks DB.

The light blue piece is the problem. The speaker will NOT realize that it's part of the Vb. It's acting like a separate chamber since the driver will think that when it narrows after the main chamber, the port will begin. The air is going to flow into the chamber made by the light blue piece, and not go out the port as planned. Not a very efficient design at all, whether or not it sounds good. And I still don't see how you can predict its performance.

How in the hell can you predict the performance of that? The light blue panel there makes some sort of chamber where you're going to get the most beautiful turbulence imaginable. What the the point of that light blue panel?

Would you be able to design it better? I sent you a PM awhile back, and you never got me back! You coulda got the 20 bucks

Ok, if that is the problem? what would you do to fix it? i'm not saying your wrong cuz i know shit about it. Just tryin to figure if i can make any last minute modifications.

What would I have done to fix it? To be honest, I know very little about camaros apart from they're easily the in the top 3 vehicles to get a decent system in. For that reason, I would have gone sealed. You cannot possibly know what the speaker is going to do with that many angles, let alone 2 chambers. The only last minute mod I would do would be to remove the light blue piece altogether. And I apologize that I never got back to you, I didn't have home internet access for about two weeks. Don't worry, you're not the only one. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If i removed the blue piece wouldn't i throw the tuning and everything off completely?

Oh and there's no way i would be happy with a sealed box.

And i don't think they are in the top 3 vehicles, thats kind of a stretch. But they get loud pretty easily. If i had more space back there, where i could just make a huge *** square box it'd be freakin awesome.

Hector, would you say removing that blue piece would improve the effieciency/performance of this box? Or would that throw everything off.

Yes, it'd throw off the tuning completely, but it's not like you can have any idea as to what it is now. That's why I said I'd go sealed, OR you could fiberglass.

Maybe, but my friend has like a 95 or 96 z28 and we seriously struggled to get a type r 10 into it ported. In the end, he just FG'd it.

the speaker doesn't realize its even in an enclosure, the speaker mearly reacts to the new environment the best way it can, it reacts to the current being applied by the amplifier and it reacts in the enclosure its in, the sub will not even see the second chamber, the only reason i called it a second chamber was to help explain but its not a secondary chamber and the air wont flow in to the second chamber the subwoofer will pressurize the enclosure including the second chamber, and pressurized air will be forced out the port like it was planed. with out the light blue piece the port will just get shortened and not only increase the enclosure volume seen by the sub, but it will also increase the enclosure tuning.
