My BiB

[Godzilla]

Thanks for the props Mikje but i can't take credit for the BIB design or the spreadsheet. All i did was put the website together. Enjoy your BIBs!

I love my BIBs too and really enjoyed the collective effort that went into developing them. There are some amazing people in this world all working towards making it a better place for everyone. I'm sure i'd still be listening to low eff box speakers costing several hundred dollars to build if it were not for this site and others like it (www.fullrangedriver.com is another great source of shared information).

It wouldn't surprise me if you $14 speakers sounded like $1000!

As you are dressing up (reassembling?) your BIBs I'd wonder if you have considered the Enabl treatment on the BIB box. I have been lobbying for some exploration of that.

Previously I had used the GM tweak of the BIB 'pennant' which was aimed at clarifying what LF comes out of the horn end.

Since mine (built for the FE127e) is all glued up and the treatment wouldn't show and I have a 167e to experiment with down the line the Enabl box treatment seems like a non invasive modification.

Alex has offered some plans on this. I'm still fence sitting about taking pen and paint to my speakers.

Hi all: (hi loninappleton)
I hadn't thought about the Enabl treatment! I'll have to give it a bit of a read. Alex from oz mentioned it somewhere else and I have been reading. My BiB are glued on the sides (and the baffle obviously) but I have left the bottom free to either stuff with wool or reduce it. I haven't found any 'feet' that I like and with a solid wooden plinths for a base they are starting to look like monoliths! I was expecting slim and tall columns...like in many of the other driver dimensions....but mine are short and fat: I'm starting to wonder if speaker cabinets are like dogs and take on their owners looks!!!???? So anyway, I could lie them over on their side and go ahead with the Enable treatment....but bass isnt my main problem...it is the high frequ from the Fostex that I'm struggling with. However, I may as well consider Enable...what have I got to lose? So far the sound is great and I like them very much...apart from friends comments whom noted the similarities in appearance mentioned above! Thanks for your comments. Rgds: Dave

Alex from Oz has a current picture thumbnail on one of these threads
and there is an Enabl calculator not far away as well. The calculator is a bit fussy though and I have not been able to load it due to a strange file extension or maybe an unknown one.

(Again, I wisht all this BIB stuff were in the main BIB thread so it's together.)

I have one short but not really fat BIB which I call the Bib Jr. I used the calculator at Zilla speak for that and using an inexpensive Pioneer 4 inch and some off-cuts and short pieces of glued up shelving.

My take on the BIB is that the driver has to sim to a long line length and that's where you get those nice lower piano registers.

I've found that changing the room can make quite a difference as well.

But we all live within our limitations.

The BIB Jr. is coming down in favor of an MLTL Fostex 167e.

ahhhh...loninappleton: the MLTL...was quite a lust for me as well! I was going to follow some of MJKing (what a man!?) and build similarly for the Fostex FE167E, but also, I liked the Bob Brines unit...it was/is simply superb...(I bought the plans and have something else to go in them!!!???)....and simple. I went for the FE167e due to so many good remarks about their clarity...even Mr Pass likes them..so I kinda figured that I couldn't lose...with such a superb design as the BiB with the "highs" of the Fe167e I reckoned I had it all covered....anyway.....I liked Decware's modified Fe206...that is what we all should base our next BiB's around! Gosh, I'd like to see/hear a pair of these in a Frugal Horn...could you imagine Curvy Chang with a pair of Decawares 8inch full range...would have to be close to (dare I say "Nirvana??)...great sound???? I have to waite until the blasted Australian dollar comes back..it was trading rather well with you guys in the good 'ole' USA, but it has died over the past months....................and therefore made buying it a stressful event.
Anyway, thanks so much for responding...I've got to arrnage some L-pads and tweeter horns for my BiB to 'rail' the highs.....and now, work out how to Enable the blasted boxes!!!!

....I've been playing the BiB (as I do every night)...and I am still amazed...such deep deep bass, from this tiny little driver..I stand there amased...how is it possible?

Physics.

That's what makes the hobby exciting. As an experiment I slapped on a 3 in Tangband onto the hole of my big BIB just to see what would happen. I took it down but even that played.

Organ recitals are good to test what your speaker build has got.

Yes, BIBs to great piano. If you like piano the BIB is one of the best speakers to reproduce it properly. I grew up with a piano in my house and know its sound.

After hearing some recordings with piano (just about any jazz recording, etc.) with BIBs and then going back to typical box speakers you realize what the BIB is doing right very quickly. The size of a piano is conveyed more realistically. Everything just sounds bigger with a BIB!

Before you add tweeter horns, ideally wait until you get at least 100 - 200 hours on the FE167E's.

You will find that cabinet EnABL on the baffles and external cabinet edges will improve the clarity of the highs.
Also, if you EnABL in the mouth it should make the bass faster and cleaner - which makes the highs easier to hear.

If the bottom of your cabinets is still unglued, try applying EnABL to the entire bottom panel and the inside walls of the cabinet as far up as you can reach.

Have a look here (if you haven't already done so).

Can I suggest that you consider EnABLing the drivers before springing for new ones (or just buy some planet10 EnABL'd ones instead).

Cheers,

Alex
