.. so a couple of months ago I build them some BIB cabs


(details here ....... http://www.avclub.gr/forum/showthread.php?t=39573)

very easy build, much more and better bass ..

and overall a better by far enclosure for the 126's

but as you all know this thing is quite addictive .... so ...

DimZ 25th February 2009 04:08 PM

... so ... now I am thinking of building something else

I am considering the Fostex 207E, the Audio Nirvna sc 8'' or the 10'' and maybe Supravox 215rtf 64 bicone ... for drivers


The size is an issue, can go up to 1.10 -1.15 m high, about 35 cm wide and up to 40 cm depth...

I like the Half Chang enclosure (very much), also Bob Brine's LT-2000, the commonsense MK2.8II (if i go with the AN's) and of course the MJK famous project 05 (the easiest of three) ....

Any recommendations / advice / help etc .. on drivers and possible enclosures would be much appreciated ...

so?


We built a pair of these funky little hybrid designs a couple of years ago, and they are definitely not a keeper - if you're looking for an enclosure for this driver that yields better bass performance, you could do well to consider either the Frugelhorn


http://www.frugel-horn.com/plans.html


http://homepage.mac.com/tlinespeaker...-sideViewS.gif

designed to use room corners, and definitely benefits from the rear deflector and "optional" supra-baffle.

or Saburo:

for something with less room placement sensitivities, and perhaps more WAF (if a factor), the FE126 can be used in the Brynn with some series R or other correction (this design shines with FE127 or Hemp FR4.5) I have built 2 of these - one of Scott's sleepers


http://homepage.mac.com/tlinespeaker...GabBrynn3D.gif


Brynn is the shorter of the 2 on the left



p.s. your second post while I was composing my reply - I's assumed you were looking for other designs for the FE126.

Don't worry, you'll get lot's of suggestions

DimZ 25th February 2009 04:25 PM

Chris thank you for your suggestions ...

The frugel was the first enclosure I wanted to build (have done all the '' to metric system) unfortunately I cant place them in corners,

The Saburo is very high (1.80 m) ...

but... the Brynn (have allready checked it) is something that I plan to build next month .... so to give another option for the 126 (and keep the best sounding enclosure and put them in the bedroom) ...

but I am searching for a new driver (bigger than the 126)

If corner placement for Frugel Horns is not pratical, and you don't mind using a sub, they still work really well IMHO.
Good Hunting!

Love your 126e BIB! Even the 6.5" fostex drivers sound better to me than the 4" because they can handle more power before sounding all frazzled. They also have a more relaxed and fuller sound. Never tried the 8 inch drivers but i have heard from others they sound even better in some ways than 6.5 inchers. One day i will have to build something using the 8" fostex.

Your post has me wondering which would sound better in corners the Frugalhorn or the BIB? Both designed for that application.

The Brynn 'looks' like it would work well with the 126/127.

Jeff - I've tried 4 different drivers in the Brynn, FE126 & FF125K (both with series R), FE127 and Hemp FR4.5. The Hemp is a great sounding driver, but not (yet/again?) relatively available - of the Fostex drivers, the FE127 shines most in this design - the double mouthed Gabriel might be better suited to the FE126.

Of course, most of my listening is in smaller rooms, and at lower levels where the 4" drivers are not overtaxed.

I recently built Austin 126s, and so far this is the enclosure that has the most potential, of the ones I have built. I still need to build the rear deflector, as well as the supra baffel. Currently the bass sounds a bit too much, though I think that will be fixed with the supra baffel maybe fixing the compression chamber volume. There is also something going on in the midrange that I think will be fixed with the rear deflector preventing sound from coming back into the horn. Mine are about 8" from rear walls, though there are corners about a foot and a half away which may be helping the bass. They have only a very slight toe in.

I have had these drivers in first generaion Harveys, and inverted BIBs.

I would suggest the Austins. In my room they are producing better bass then Half Changs with Pioneer B20s in them. They still have the midrange greatness of the fe126 driver.
