Terry Cain's BIB -why does it work and does anyone have those Fostex Craft Handbooks?

I am curious about the 'BIB'.
Can someone point me to where the descriptions are please? My eyes are going wonky scrolling through heaps of other interestingly distracting things but never catching up with the BIB. TIA.

I'm taking this up because no one else has answered. The BIB can be seen at zillaspeak.com and the calculator can also be found there. Over the years there have been many BIB builds. And the calculator loads into the free suite called Open office which I use rather than MS product. it's not the only floor stander I've built but it remains the favorite.

Early BIB's can also be found at the companion site for DIY Audio full range called Full Range Driver Forum: a mature and respected forum from James Melhuish. It was my introduction to the hobby.

More traffic here though. 🙂

Stephen,

Zilla's BIB site might be down. Here you go with a great introduction to BIB (Bigger Is Better) from Terry Cain himself (unfortunately now passed away):

Single Driver Website

The thread we are on is a humongous one on BIB. A few words on BIB speakers:

* BIBs are easy to build - great for first FR project
* Music reproduction is very satisfactory according to most folks who have a pair (including me)
* Needs to be placed near corners to produce powerful bass (and can produce plenty)
* The design can accept many drivers - the BIB calculator will give you the cabinet dimensions once you input driver specs/data
* Cabinets are usually big (it's named Bigger is Better!)
* You can adjust the poly-fill stuffing and tune the speakers according to room and taste

Ar you planning to build a pair? 🙂

Yes, unfortunately the BIB site is down. I was going to try using WordPress and rebuild the site this weekend but was side tracked bc of father's day. My intention is to rebuild the site with most or all of the information. If you want the BIB calc, please email me at ZillaSpeakers@gmail.com... i sent 6 out this morning via email.

Since changing jobs i lost access and the ability to modify the site. When i moved ZillaAudio.com to GoDaddy i left a few links and pages out by accident and feel so badly about rendering the site nearly unusable. I have the data but need to set it all up again. If you need the calc email me and let me know what you plan to do and i will double check your input and provide any suggestions i might have.

I love my cheap BIBs using the cheap Dayton's and also love my more expensive (but still not too expensive) BIBs using Fostex 165k... i bet the newer Fostex will also work really well! Efficient drivers with a forward sound work well in BIBs bc the bass from around 300hz down is boosted by the BIB design. This can be altered simply by stuffing to taste. They fill the room like no other speaker when place correctly into corners.

I love both OB and BIBs... imo, my two favorite types of speaker designs.
 
Hello Ion
Thanks for the response and information: Also zman, zia and zilla.
For about 40 years I have promised myself I’d make a “reasonable system” and if I do not do it soon my recall notice could be served first. 🙂-{
Starting from an arbitrary collection of ’noise’ generators I hope to come out with a respectably featured set-up. I am leaning the SS way, with a kit, probably GC. I’ll start with the amp and if I do something very non-PC with things only the ancient speakers may be up for sacrifice. Following that some good audio transducers, well housed.
Got sidetracked [again], here with BIB references; sounded like it needed checking-out.
With a listening space less than 17’ x 17’ there is not much real estate for parking a couple of behemoths; they're not that big?? I have not taken time to follow the URLs before cooking dinner, lol.
Maybe I will be better off peeling back some drywall and inserting sealed, tall, narrow and skinny enclosures. Too many options!
The FH3s seem within my ability and appealed because of their narrow, rectangular footprint – along with not coming across any unhappy responses. Construction’d be a lot more straightforward than the Chang Family and some others I found.
Wall-mounting/recessing new cabinets is a real temptation here with the continuing earthquakes over 5 Richter.
So far I’ve been lucky with the TT. The arm has always been clipped down so there are no skid marks or pot-holes in the platter-mat.
Maybe this is a good time to get a flat screen nailed up on the wall, mount a semi-recessed speaker either side of it and that should leave be room on the floor for an ‘extended base’ setup. (I'll have to put a doily under a pot of African Violets on the base-box and the better-half may not notice? mmmm . . . !)

Nomenclature: OM - what does that stand for please, 'old man'? Morse code was plenty and now here is another "language"; is there a summary of all these somewhere??
 
Stephen,

BIBs are big, but pushed into corners they are not that obtrusive. FH MK3 build will be not quite as easy as the BIB, but still very much doable. Much smaller in height, but depth will be very similar as the FH3 base is pretty deep. Very sweet sounding speakers, owners say. There is a very good thread on FH MK3 builds also.

17' x 17' is decent sized listening space indeed, and with a good set of speakers you will be having fun.

For simple build and agreeable size two more designs come to mind - the Pensil series and Micro Towers.

FWIW, I spent a couple of hours this past weekend on my first listening session in the best part of a year with the FH3 / FE126E, a combination that really benefits from corner loading for full extension / weight in the bottom end. In a room as wide as mine (15ft) and with the enclosures angled at 45 dg, I found the furthest listening position that still gave me a well balanced off-axis frequency response (approx 10-12ft) was still close enough that channel separation was wildly exaggerated on some material, and imaging wandered. This would likely be far less of an issue with a 5.1 surround system, as center would be filled by a "discretely" mixed channel, but I certainly found distracting on music only.

Chrisb,

I am using my FE166en BIBs near corners of a 20 ft wide room (should be 17 ft gap between the speakers), ~45 degree toe in, listening from ~13 ft. Haven't tried it with lot of material, but separation was still within (maybe just within) acceptable limits. Again I haven't placed the speakers any closer, so would not be able to comment on tighter integration from placing closer - but now that you point it out, maybe they are placed too wide...

AFAIK FH Mk3 with MA drivers should be able to do fine with placing close rear wall (no need for corners).

As I implied, it can be very program dependent - a live venue recording of a massive group like Loreena McKennit Nights at the Alhambra was well served by the scale of soundstage and less than laser focused imaging, whereas intimate / closely mike recording of small group (Wailin' Jennys) can be all over the map from track to track. I've heard both of these groups perform ( the Jennys twice), and mentioned to Dave earlier today that it's very interesting how our visual memory of such experiences affects our visualization of the reproductions.

AFAIK FH Mk3 with MA drivers should be able to do fine with placing close rear wall (no need for corners).

I'm sure you're right about that, as no doubt anecdotal reports from other builders will confirm - some of us have limited time and space to test every permutation, and tend to get stuck in a pattern of "favorites" . By this coming weeks end, I'll likely have a chance to try at least 2 or 3 other combinations.
 
FOXYE,

The calculator will give you the measurement your BIB - height, depth, width, driver placement etc. I am attaching a screen shot of one of Zilla's BIB calculators that has a construction diagram. Picture of my BIBs also given. 🙂

Dave (Planet10) made a 3D visualization of a BIB which gave a pretty good idea on which part fits where as far as I remember that was on Zilla's site also. Sadly that page is down!

If you are really interested in a BIB mail Zilla. I have a pair with Fostex FE166EN and they play impressively. Mind it, with FE206E you will probably have a very tall set of cabinets (>7').

Regards,
Zia
