6th order

[Darkmage1991]

can anyone design a 6th order? i purchased a single MCM audio that was recommended over the tang band sub on caraudio forum( this: http://www.mcmelectronics.com/produc...-2421-/55-2421 ) and would like to make a 6th order and suspend it from my parcel shelf in my taurus and fire the port into the cabin. but i dont know where to begin designing a 6th order (i can do 4th just not sure on a 6th)

looking for about 28hz-80hz range its gonna be a small setup (obviously with using a 8" sub) im aiming to make something that makes a punch without taking up any trunk room i will Power it off my cars stock jbl sub amp (about 30rms)

there used to be a few guys on here that could design them but not sure if they are active anymore.

i aint asking someone to sketch up a design. just looking for what the 2 chambers should be tuned at and size.

When i punch the numbers into some of those online calculators the gain is in the negatives which im sure you dont want that. so im a little bit lost

keep it simple, a 4rth will be just as flat, plus you will need twice the room

I actually run those MCM subs, and in 3 builds have done a 6th successfully. I'll see what I can dig up.

anyways these subs work well vented or in a 6th. They really prefer alignments like that. I would not personally recommend sealed or 4th order band passes for them. Also I had meh results with a transmission line in my apartment, but that's not really applicable here. Anyways long story short I bought 8 of them when they went on sale years ago and have been selling them since. So these subs I have lots of first hand experience with.

Things to keep in mind is they won't tolerate over excursion, so don't bother trying to play anything under say 33Hz. On music they're great, but if you try test tones or some music with very deep bass you'll probably bottom them out. They're not quite as forgiving as the tangband W8 740C that they imitate.

Anyways I'm scouring my dropbox for the design I had. I'll report back later.
