I modeled one up in Sketch Up for the fun of it to see if I could model whatever the heck I wanted to. I didn't do any measuring beforehand, but I can tell you the box will be fat and huge.

 

On another note, I just got a job! On 11/11/11, National Metal Day!

it will be huge, temperamental, and overly complex. Using it isobaric loaded will also mean output will be rather low.


I am protesting Skar by giving them added exposure in my signature.

Could you remedy that with using a thick enough baffle?

EDIT: I just did the math, I am full on retard.

Yeah a box like that would not only be hard to build, more than likely not worth the trouble. My current favorite box type is the Tline. Get great output if built right.


Current Set Up:

1998 Grand Prix GTP Coupe

Kenwood BT-900 Head Unit

Memphis Power Reference PR-50.4 for the front stage

Mmats 2100.2 amp (Want a Sundown 2500+)

Bose Tweeters, RF T series 6.5's, Need some 6x9

Ascendant Audio Mayhem 15 with stage 2 coil mod (in the back seat for now!)

850 CCA front battery, NSB 180-FT rear battery

2 runs of 0 guage, 1 run 4 gauge, Stinger RCA's

Looking for H.O alt, 6x9 speakers, tweeters, JL 300/4,

the whole point of isobaric is sq and space saving. box is small, clean tight, and quiet.

I'm like 99% sure the OP is just trolling

 

Thank god! Because I was only 98% sure.

Haha! Ramrod..

 

Point being, you wont find someone to help you with something like this - and even further, design it for free (if at all). 6th orders take a lot of time and are a large balancing act, another port makes it a big mess.

 

Give us a better idea of what youre working with, and perhaps a more practical solution can be had.


I do stuff :)

so, was the point maximum efficiency from little power? real narrow response?


*IF I have forgotten to exchange feedback, please let me know*

i buy broken amps....

No, i will not "gift" paypal. please do not even make it awkward by asking. if the fees are an issue, I am usually inclined to add them. unless you have discount elsewhere, shipping is through usps flat rate, through usps parcel post, or through the roof..... i am in alaska. thanks

So, how did it turn out? A quasi tuned enclosure just offers support for the cone below the tuning frequency of the (low tuned) side of the box. Be careful though because too much power below tuning can damage your sub inside the box wherre you can not hear it...
