A tiny bit of help please...
A buddy is building up a small single ended 6V6 SET to run with an IPOD for his daughter and he wants a small set of fullrange speakers for her bedroom. Has any one here built any 3 inch BIB's. Dont know which tiny drivers would work best. Any recommendations? Height is not really an issue so 4 or 5 feet tall is ok (not likely they will be that high) he wants to keep the width depth as small as is reasonable. I assume that a low Vas driver is what is required to keep the dimensions as small as possible. Thanks a lot for any input. Regards Moray James.

I plan to build my 3rd BIB using the TANG BAND W3-871S 3" DRIVER, nformation here:

or build my 2nd one, using 4" fullrange here:

crazy thread, great thread, OMG...
but of course I have a question! 😀
Any reason why (or why not) I shouldn't try out the BIB concept with a "standard" 2-way/3-way? Or even as a sub (OK, I know it gets big then 😱 ) My idea of the day/week is to build a Seas CA18 2-way and "do something different" than standard BR or even MLTL.
Thanks. Awesome thread. If this has already been asked, please be patient...

This is not a BIB but as a construction project, is bound
to amaze your pets. Take a look at the "David" by
Bill Fitzmaurice. The David has a chamber for an MTM
or MT configuration and a chamber for woofer
arrangement.

BIB is basically a bass-horn alignment that happens to be pretty acceptable for FR purposes (OK, it's more than 'acceptable' but you know what I mean).
Moray James. I'd probably go with something like the FF85K, but in a non-folded QW version like the Cain & Cain Noogi as the Fs of 3in drivbers really is a bit on the low side to be woth loading in this fashion IMO anyway. Sorry I didn't reply to your last email by the way mate: there's a very very good reason though: it's only just arrived in my in-box, dated a couple of weeks back, in a somewhat corrupted form. Hotmail mucking me about. Again. I do apologise -if you can remember what it was about (a half-wave device of some form or other I belive) do resend and we'll pick up where we left off.
Dan: Hemp Monolith is a Very Good Thing for life, the Universe and everything IMO. Wish I had the funds and space to explore properly. At present I don't even have space for a pair of proper BIBs or double-horns.

I just found out about TCs health problem. I have been down that road recently and recieved a great deal of support from my many forums (yes i belong to many not concerned directly with audio). It was this support that helped me in my recovery to a great deal.
Lets all get together and help Terry as much as we can, there is a site (which i cant find at the moment) in which various ppl are donating equipment for re-sale to support Terry.
We cant let such a talented craftsperson and generally good guy to be neglected during his time of need.

Amen to that Ron. I couldn't agree with you more. For reference, here's the site, run by 6moons audio: http://www.6moons.com/showcase/terrycain/terrycain.html
Please forgive me for not wanting to read through this thread to find the answer, but can anyone tell me whether a bib is suitable for a fostex fe206e?
Yup. But you better like 'em big. See the one I did at www.zillaspeak.com/bib.asp on the pages Jeff so kindly hosts -click on the Fostex tag.
If this is a trifle too tall for your taste, you can keep the HxW dimensions and reduce the height to 70in and Zdriver to 30in.
Alternatively, see Ed's superb folded TQWT at www.vitalstates.co.uk -basically, a kind of 1/4 wavelength tuned, inverted BIB (BIB is 1/2 wavelength long) I heard this a couple of weeks ago and came away very impressed. Cracking design. Go to the Vofo link.

Indeed, it will produce excellent sound.

Thanks for that. Wow, 174" is kinda tall! Not sure I wanna cut some holes in the roof though.
Also, what do you mean when you say I can keep the HxW dimensions and reduce the height? Isn't H the height? Little confused.
And thanks for that link, another design to consider!
Typo -I meant the WxD dimensions. Sorry about that. It wouldn't be 174in tall, but about half that -you've forgotten theyre folded. 87in still isn't small though, but it works. . 😉
Ah ok, I see what the line length means now. New to all this! Just trying to find the best design for my fe206e's thats also easy enough to construct for a woodwork newbie. After reading this thread http://www.diyaudio.com/forums/showthread.php?s=&postid=1071539#post1071539, do you think the fostex fe208e enclosure would be better or worse than the bib? The vofo sure looks good however seems difficult to build.
What's in a name?
Well,
With a nick-name like mine, I just *MUST* make a pair of these.
Got myself a pair of FE127e's friday, and I'll make them burn-in this week.
Should I opt for 43 or the 63 sq. inch 'version' ?
My room is about (roughly) 4*10 M, 2.5 M high or so. They'll play across.
Thanks,
BIBster... (He bibs, therefore he's a bibster 😀 )

Bigger Is Better.
wixy -they're somewhat different in their presentations, so it's chalk and cheese really. Both are extremely good; the BIB has more extension, but is of course much taller, and ideally needs a rear or side-wall at the very least to load. It has a dipole sound to the bass, and some serious power down there. The 208 cabinet won't go quite as low, but is just as powerful down to the mid 30Hz regions, and is probably a little more domestically acceptable as it's far shorter, and looks very good. It's a lengthier build though. Not particularly difficult as it's all right angles, but takes longer. Both will work very well in large rooms, so it comes down to where you can position the cabinets.
Vofo is theoretically a very easy build -just a box, with an internal sloping panel, like the BIB. it's the details that probably you're thinking of -the curved internal baffles, and the curved slots, right? For the former, you could try flat, angled pieces, the latter, combining them into two large slots, which shouldn't make a difference providing total vent cross-sectional area remains the same as Ed used. It doesn't go as low as the other two, but to about 40Hz, it's not lacking in LF punch -down to that frequency, it kicks you like a mule in the upper chest, especially in a decently proportioned room.

Read post #28 by Bruce. Scott, you may like this! Bruce built several cabinets for the Fostex 103 and liked the GM designed Voigt best until he built the BIB. He feels both designs have something to offer as well as the tall thin Zigma.
His efforts to find a good cabinet design for the 103 started after he built the recommended enclosure and was not satisfied with it.

Scottmoose, thanks for your advice, I am thinking I would like to try the bib design.
Could you recommend any particular dimensions, width, depth etc, more ideally suited to the fe206e?
Would 18mm plywood or mdf be suitable, or would thicker 21mm wood be more suitable?
Do the cabinets require internal bracing?

WxD wants to have a ratio of 1:1.4142, rounded to the nearest sensible figure to preserve the conical profile. Length you might as well simply /2 to get internal height. Zdriver is easy enough to follow. 21mm ply would be better IMO as it's a big box & it should help cut down on panel resonances. Might be a good plan to make the internal baffle out of particle board. I doubt you'll need any internal bracing -the internal baffle helps in that respect.
