Good to see you back Vivek & how the hell can we forget "Your" "CCTB", it's one of the finest jokes to be ever played on Navin!!!

He has done it already..

And welcome back sir.

any freeware which can do the same thing?
LspCad has a freeware version of it called Lite.
LEAP & LMS was with a friend. He has moved so access to it is now a little cumbersome.
Clio and Calsod I dont have anymore (I used it in the days of DOS).
If you can find MLSSA it is probably the best. I have not used WinISD too much, Vivek uses it I think.

Stiffness is the key. A speaker box needs to be light (so that it stores as little energy) but stiff.

you just cant believe how much strength and stiffness a corrugated box or board can have. and it is light weight. but still it is not half as good as mdf or FG. for testing a driver in a corrugated box it would be difficult to mount the driver. also difficult would be to seal it and the fact that it doesnt have the same strength in the bends as the rest of the board. So IMO cctb would give you an idea of how a driver will perform in an enclosure but will not be accurate enough due to the strength loss in some areas of the box.

i think i should give it a try and find out and let you guys know how it performs. i have an advantage that i can build a box of any shape and size with the max strength possible with what we have. maybe i can test my hertz 15" in a ported cctb before building an MDF enclosure. what say guys?? me kidding hehehe.

cheers

Due to the overhang of your tub-sharing advice in the other thread, I misinterpreted this sentence in the first attempt

Why not? CCTB itself is such a breakthrough technology, but you can also try even more advanced technologies like "airtight leather bags with polyfill" (http://www.team-bhp.com/forum/diy-do...tml#post472018)

Maybe I should patent the CCTB.
Navin, my subwoofer boxes (the MDF ones) are making excellent progress.

you should vivek. and im getting serious about testing my sub in your technologically advanced enclosure. :-) (i hope im not offending you in any way, let me know if i am) may i use your technology vivek?

iit will be virtually free for me to test the sub.

thanks
clip

lets just prove it that it is a good technique to use cctb as test encl. i will build a box which will have strength compareable to mdf. im sure i can do it and no one would joke around. so now im on mission CCTB Mfd by leader paper processing in technical tie up with Phadnis Acoustics.lol

Clip how well will CC mate with polyester resin. CC by itslef will not provide a high enough bending modulus but (tkaing clip's word on it's stiffness) if we impregnate CC with resin it could be cheap and good.
