Thanx ... the "official' plan is the one without the wedges... The wedgie version is the "with icing" version. Originally conceived as a way to make them easier to build, it is actually the opposite.

Thanks Dave.
I was reading a post about the adventure in cutting the wedge because that was what I originally going to build. I decided that I did not want the hassle or waste.
the void is foam filled and I am using 3M thinsulate as a liner in part of it. I still have to shrink the CC chamber but do it in a way so I can open it up from the driver hole.
I plan on a extra piece of wood behind the driver with a 3 inch hole that can be covered by the solid wood roach unless you think that may be a bad idea
I believe my adaptations simplifies the build even more and the enternals are made at the same time identical to each other on a pattern so I don't get any measurements wrong.
the top above the driver was out 1.5 MM and I had to add a piece to make up for my mistake, that why some glue shows up there.

I'm not quite understanding you there... i thot a roach was what was left-over when you couldn't finish the joint 🙂
Anything that makes the inside of the CC irregualr at the same time as shrinking it down to the right size is a good thing.
One thing that we haven't had time to try out yet is the kind of swiss cheese magnet brace we usually put into all our speakers.

That would probably be worth installing on the double horns too. Second cabinet was held up due to rain (have to cut / sand outside) but will be completed later today (though no finish applied)
I am likely using the term wrong.
I am refering to the 4" plug of wood that I cut out for the driver. so I put in the smallest CC but adding an addtional piece of wood that is not in the pics behind the driver. This will have a 3 hole in it that can be covered by the left over 4" piece.
Sorry I have trouble explaining things.

A pair of Frugel-horns built in Norway.
Level-0 build for FE126E. They will be used in a small room.
These will replace my Fostex recommended BR/Horn hybrids which have been used to break-in the drivers over the last 6 months.
A question of damping:
What are you guys using for damping material, if any?
In the Fostex recommended box I used tick felt behind the driver with good results to dampen reflections back through the cone (being carefull not to obstruct the airflow).

An externally hosted image should be here but it was not working when we last tested it.

So far we haven't played with anything yet (bar a fat piece of felt on the back of the 126 magnet) ... as we get a couple more pairs together (the 1st beta of the flat-pak is sitting on my back deck, all glued up, just waiting for me to spend a bit more time with them) we'll get a chance to play. I haven't heard from anyone else either....
damping & CC volume for various drivers is still an area that needs more exploration.
dave
I'm using felt on the driver magnet, and a thin piece of felt on the
(angled) rear wall of the cc.
The more I live with 'em, the better I like them.
If anyone's looking for a very worthwhile blh project, look no further.

The 1st set of prototype flat-paks have been built... the picture is of the last panel being attached... this gave us some hints to rejig a few pieces to make them easier to build... one thing for sure, without any clamps or metal fasteners they will need to be built slowly to let the glue dry on subassemblies
a picture show will be assembled and poted shortly.

hello all,
what is approximately the horn's cut-off frequenzy with the small compression chamber (2.35 litre), the medium (4,06 litre) and the large (5.85 litre) compression chamber?
greetings

So far with the recomended drivers only the small CC is used. The others are there for those experimenting with other drivers.
I don't yet know what the real cutoff is, but the target is 200-300 Hz....

hello,
what is the upper frequency cutoff when not using the small CC but the middle or large CC with the recommended drivers? can you tell me something about this?
greetings

No point in going any lower than where the driver starts rolling off -- 200-250 Hz of the 126 & 108.

well, my frugals are done and now I have to find a place to put them.
My son was out for the evening so my daughters wife and I listened to them until late into the evening.
Pipe organ music is rather interesting I hear some low notes but none of that Familiar vibration whatsoever.
Some rockin/bluegrass is missing a range of lows that I am used to hearing. The sound quality is pretty good but it took awhile to get used of the the lack of bottom end. I then realized that I may have been listening to exagerated bass to long. I did have a sub planned to augment the bass but I think I'll get them placed and leave them alone for a couple weeks.
I did have them set in corners and played with the placement quite a bit without a sizable differance. When I moved them out from the corners and flat to the wall and everything suffers. To me reflection becomes more severe and the need for a baffle increases. But thats just me and this is my first BLH ever.
One CD sounded woody & hollow but it was only one CD that had that odd sound, I never heard this odd sound in any other system with this CD. This made the CD awful and moved along to other music. If it continued in other CD's I was going to add some dacron to the CC but it was only that CD so I left it.
The biggest thing I noticed was the imaging and they created a larger stage than other speakers and I was making out sounds I never noticed in the music I listen to. They are excellent for voice and blues and I am considering playing with the 127 in the frugal for mains in a HT set up. someone was trying them with the 127's and I am wondering how they turned out.
I used the smallish CC in my build with that said.
They are a beautiful looking speaker and once they were done assembly they have a very high WAF and I can vouch for that now that I have mine done.
I still have to do some fine sanding and add a finish. That will take longer than the build and Will have to be done inside if I can get away with it.
My wife is not to fond of my latest hobby but loves the look of them and enjoys the sound. She feels the sound is more natural and far less annoying than other speakers. ( I wonder if she knows more than she lets on sometimes) Maybe I have been building the wrong stuff the last couple years 🙂
Anyway thanks to All those who had gone before and convinced me after postive reviews to build a pair.

gexter,
I was the one who built Frugels with a FE127. It turned out quite well. I actually had 2 other diyaudio members come over last week to listen to them. We moved into the lounge and were able to place them in the corners, unlike in my dorm room. I'm very happy with the Frugels. My drivers are nice and broken in now, and bass is significantly better. Adding polyfil to the CC made a HUGE difference. My friends were in my room at the time and all immediately knowticed the difference. I didn't measure SPL, but we listened to a bass cd and it did pretty well.... good for a 4" driver. Not as good as my Pioneer B20s nor as good as any subs 😀 . But they did pretty well. We were all suprised at the extension.
I haven't listened to other speakers in months, so its harder for me to compare. I will ask them to post, since they have other speakers to compare to.
All in all I'm very happy with them. If they could be corner loaded all the time it would be much better, but my dorm room is soo small. Bass is good, but being the teen that I am, I prefer more bass. I think that people could definately live without adding a subwoofer, but I'm not one of them, thanks to my music prefrences and how I like my music to sound.
Good Luck,
Josh
PS How many hourse have your drivers been braking in?

Send me pictures, i'll get them up in the new gallery. membersip #s?? I guess you are the 6th build to make tunes that i'm aware off....

Despite what Ed says the 126 will require some break-in... and much of this is in the bottom. Still the Frugel Horn is never going to be a bass monster, the bass it does produce is articulate & well-defined (at least in ours). They will also telegraph your amplifier sonics like crazy. A SS amp with a high damping factor will tend to give lean bass.
dave
PS: pay attention to what your wife says, in my experience they usually don't speak up unless they are really good, or really bad....
