my FE207 DBR
Hi all
These are just my FE207 DBR, no filter, directly wired on KR842's and they already sound quite good!
It's regular fostex enclosure, which is fine for a start. Next step is perhaps a FE208 in back horn. We'll see 🙂

my little contribution
Hi, long time no see 🙂
My old full-range project... Clabby aka Abby Clone.
I am now working on a new project with the FE208E... (ML-TL)
By the way, anybody know the type of speaker in this old Altec Lansing Seven? I need to change the surround 😛

Nice Clubby's.

Try the Lansing Heritage Site. Also, some one watching the Altec thread may have some. Great Plains Audio is worth a try.

Re: My BIB's
Do I spy with my little eye a pair of MCM 55-1200?
Great little drivers 😀
Have a pair with a peerless HDS tweeter in supertweet config (10k XO, no coil on woofie) in a vented box, plays music real good.... not using any baffle step, but haven't worked the XO much.

Re: Re: My BIB's
Well, here are my first BIB's. I have gone a bit of a different route on these. Due to terrible room acoustics and the fact that these may migrate to the theater room, I have added a tweeter. The driver is a Pioneer A11EC80-02F 4.5". I got these for a good deal and wanted to use them. I also had a pair of Dayton DC28FS-8 1 1/8" silk dome tweeters laying around. I coated the pioneer with 2 coats of Damar. This tamed it's wild HF and improved their looks. I used the Fostex 126/127e model for the BIB since the 126 was the closest match to the driver used. The wood is 3/4 birch laminate ply. The front baffle is made from some leftover pine 1x12's I had laying around. So far, I am very impressed and satisfied with their sound. They have overcome the room acoustics, and fill it with clear sound. I have not noticed them lacking, or having too much thar a little EQ tweaking can not take care of. I do say this after a few tweaks on the tweeter x-over. I realize this setup somewhat defeats a full range BIB, but, for the mild cost of $125 that was spent on the pair, I think I will keep them.

Stamm Drivers
Does any one have contact details for Richard Stamm,I have a Stamm Driver in need of repair. It is from a pair of Loth-X Troubadour horn loaded speakers, the best speakers I have ever owned, but with the demise of Loth-X have been unable to repair.
Hooked on that fullrange sound. Eric www.vintageaudioworld.com

Very nicely done 😱
Here's my 126e in Angular Spiral:
An externally hosted image should be here but it was not working when we last tested it.
Here is my first attempt at loudspeaker building, I've used the CSS FR125s in a solid 25mm thick Iroko hardwood box, ported with a solid machined alu port.
I'am sure natural wood has a better sound than mdf.
These have replaced a pair of Dynaudio Contour 1.1s, in my opinion the midrange is in different league, do crossovers effect the sound that much?

When it 1st came out, i did a speculative design for a small aperiodically loaded FR125. Here is a realization -- 4.5 liter aperiodically loaded CSS FR125S.
They work very well. The picures don't convey the color very well. The cherry veneer is probably closest to the picture from the front than the other 3.

Thanks for the plans, I have some Iroko left over and my daugther likes my frs' that much she wants some.
The slope on the rear? and holes near the bottom?
The slope on the rear? and holes near the bottom?
The slope on the rear makes the 2 most critical opposite surfaces quite non-parallel (parallel walls in a box this small could have some nasty consequences). The steep angle also gives a place to put the foam damping that makes the joles aperiodic (we struggled with a way of doing the ports easily and ended up lifting this configuaration from Bill Perkins PR-2s)
There are 20 - 1/4" holes

Dave, your design is also a great way of testing/comparing smaller w-range and mid-range drivers. In a multi-way system, possibly the best midrange enclosure going. We tried an internal panel to steer the reflected waves toward the lower corner. It was a waste of timber. The 60 deg seems optimum.
We found you could listen to the driver without any "box" additions to the sound.
And very high WAF.

Geoff.
