I need a very easy to build Subwoofer maybe a bib? Help please.

[fatbattery]

Gday I had in mind making a bib. I never thought about making a horn bass to seriously until I saw a bib last night. It seems like something I could build . I know this is not the first time this has been tried. But the thread was too old to ask about it so I thought I would start another one. Not specifically regarding the bib. I just something simple. A bib has the advantage of being used as a bib allso which would be fun too.Can I make tight clean bass from 150 to 50 or lower? I probably will end up going full digital crossover with delay in the form of this product. I will build a preamp using the balananced dsp using digital inputs from my paytv, pc and blueray trans coupling the analouge outputs to davens. Only 2 way to start and using passive crossovers in the speakers and amps or some combination anyway.Thanks in advance.

Hi,
you're thinking to make a BIB with subwoofer drivers, or use a BIB with fullrange drivers to have an easy build that doesn't need a subwoofer? (Either ought to work.)

[fatbattery]

Iam thinking trying them with fullrange if it possible to build it to suit both or just a woofers other wise. The last tqwt I made had a huge peak and also a place where the drivers completely unloaded. I did have in mind quiet a small driver for woofer dutys . somthing that was fast and nimble for low volume work. Somthing from my collection hopefully. richard allan cg10 perhaps? 99 db efficient. Then maybe try a cg10 t fullrange.I dont have a lot of really nimble 8's only klangfilm type 8.5's that are made for open baffle. Some corals too. Would be it be better since it will be used for bass duty to build a little compression chamber on the front and make it a proper horn? I have contacted a guy at my local woodworking club that said he can help me which is encouraging. With a compression chamber it would be a very good horn being nice and long and strait would it not? rommy the cat says anything that isnt a true horn will sound like shouting down a sewer pipe.

I think I put this in the wrong section. I think adding a compression driver is incorrect to as a tqwt has a compression chamber already :-|

High Efficiency Speaker Asylum - RE: Altec288 wood hyperbolic plans anyone have any? Some MJ plans here too. - tubebuilder - January 14, 2011 at 12:53:20 Here is a pick of my bedroom system in another thread. You can see how the top firing would be a great advantage for me. The ceiling area is the most uncluttered space. I have found a thread on the 12inch bib but it is far to big for me. I would want a narrow ten inch bib. Any bigger I fear it would get too resonant. What you can see in the pick is a crude pair of open back cabs with some rare grundig radio drivers. This is where my mid bass and mid horns would go. The bibs would slot in on the outside. I could use the reflex underneath for low bass but I doubt if it would be necessary in such a small room.I could use a 8 inch bib but it seems kind on silly though since I will be using a 12 inch for mid bass with all over 100db efficiency's. The only other horn option is Dr Bruce Edgar's show horn or monolith. Both are huge projects.

Google is your friend. Found one of my old posts right at the top: Fullrangedriver Forum / Enclosure for Richard Allan drivers

He's right if you don't damp it some.

Gday GM I do google a lot but perhaps Iam not good at it. I have just came up with a horn that would suit me. So I guess I will keep reading to see if I can learn enough to make it. I have been reading more about BIBs Iam sure I will work it eventually.

Greets!

Maybe/maybe not, but I'd forgotten that me, Cal (mod) and a few others did a Google comparison awhile back using identical searches and the discrepancy between us was considerable. Apparently, its 'A.I.' creates searches based on what we search and/or links we click on, so having already posted on this driver it seems reasonable it would pop up on the first page.

Regardless, on stuff you don't normally do searches on, you may need to wade through many pages of links to find it. I tend to copy/paste or write a fairly complete description if there's enough info since Google seems to not get bogged down by it like most search engines, i.e. 'less is more' when defining a search.

FWIW, with yours, I searched 'richard allan cg10 bib'

Anyway, what do you need to know to build a horn? I mean, if you have a design.............

Is space a concern? If not, look up BBBIB, it is running a 12"LTA driver if I remember correctly. They should have plenty of output for you.

OmG the more I read the more confused I get. Front horns designs are getting to big and are meant to floor load. Which doesn't suit my room. I have been reading horn response tutorials. I fear even if I did work this out I would not get a successful designed first time. I read peoples websites and most often they build series of horns before they get it right . I have been reading about tapped horns. I understand they are increasingly popular for there flatter response and lack of corner loaded needed thought it still benefits. I cant help thinking the bib has a lot in common with a tapped horn. I am thinking if a mid horn can be folded even if once 90 degrees. I am all so reconsidering going back ot a tpi style wave guide for mid duty's.

GM I did read about Sim for the Richard Allan. It was just to deep for my room by about 4 inches. And a little tall too I think. Iam sure there is better tapped horn plans out there more suitable for my needs. I just have to find the right one. I should reread the BBBib At least its a proven design. What put me off about this one in the fist place is that its so big and wide it would have to resonate. When I asked about a Richard Alan bib I had these fantasies that it could be much narrower thus reducing the risk of resonating. I think this is where folded designs are better. I suspect Volvo worked this out because her uses a smaller folded tapped horn for his upper sub bass and his bigger one just for low low bass. This is getting so complicated. I had cabinetmaker waiting for a plan. I realize now it could take 6 months to get this worked out. Perhaps I will assemble the mid treble into a reflex then work down. Oh and Iam still tempted to just build some small chambers on the back of my Auzuru 150 Lcleach tratrix horns and see what happens. Trying ten and 12 inch drivers. Because they fit in my room and are the same shape as my upper mid horns almost!

Most importantly .I do realize I have been asking to many questions and not read enough. So Iam going to stop for a while and give peoples a break.
