Thanks I thought about that but it would be a challenging build to keep the design ethos, a straight stack looks quite odd.
@ markmaxwell: fantastic finish sir... I've just started gluing my FH3's and am hoping to do / achieve a white high gloss [piano] finish. Using Alpair 7.3 drivers 🙂

Progress
Hi,
Having got my kits from Colin a few weeks ago, some progress has been made in getting them ready... As they stand this evening, the American black walnut veneer is on and have also applied two coats of primer/undercoat, which I'll sand tomorrow 🙂
With the MA Alpair7.3's fitted, the FH3 do sound very good. Very impressive indeed, particularly the lower end performance.

horn
Hi There
I do need a horn of this type without corner loading, I have a tapped horn for the sub bass, ( moment I do play with a T-TQWT and open baffles) .
I want to experiment with some type of boxes, I see for this horns I need a speaker with low QTS of 0,20 to 0,40, trying a speaker with a QTS of 0,76 did make strange outcomis in hornresp.
regards

Kees,
try AJHorn. A mad scientist can do horns with drivers of completely impossible TSP.

Hi all;
Do the FH3's (using, say, MA Alpair 7.3) need to be placed in a corner, or will they do OK bass say 1m from a back wall? I'm not used to big bass anyway, so I'm not expecting subsonics... 🙂
Cheers

No
Yes.
Final bass "quantity" can largely be controlled/fine tuned by the amount of damping under the driver (ie closer to the terminus)

Apologies for resurrecting this old posting but I am intrigued about something.
On youtoob there is (was?) a recording of an Italian guy that had build the hybrid FE126 hron, did not like it and in the end finished up putting the FE103E in it and it started to sing.
I'm most interested to hear if the FE127E would work in the hybrid instead of the FE103E. Thanks!
From our experience the Fostex recommended hybrid horn/BR is a flawed design. Try what you likein it, we eventually burned ours.

Yeah, I am well aware about the negative opinions of the hybrid design for the FE126En however I remember another design that did not work well and driver after driver was tried until if I remember correctly the FE127E was put in it. IIRC it might have been the PAWO.
The Korvu website has a number of hybrid horn / BR enclosures and what I can determine from youtoob they seem to work OK which leads me to believe that a horn driver is not working as good as a BR driver in that hybrid enclosure.
The metronomes are amazing but I just do not like the soundstage above my head and I like a little more output than that those FF105WK can produce.
I need something that has a higher efficiency and the FH Mk III is not a good fit on top of my desk. And hence I am wondering if the FE127E in the hybrid might work or if I just should commission the BK101 to be made.
If you are interested in the "hybrid" design principle, why not build (or at least investigate) MJK's highly engineered version (see page 9): http://www.quarter-wave.com/Horns/BLH_Design_Article.pdf
Not really the same thing, but interetsing. We built an earlier version for the A10 (didn't have the helmholtz resonance trap in that iteration)
dave
MJK BHL has an internal helholz absorber to counter one of the unwanted 1/4 wave resonances, the Fostex vents to the outside so you have an additional source.

Thank you for that link - had seen it years ago when I signed up to the worksheets but had forgotten about it. Unfortunately those will be an ill fit to put on top of a desk - perhaps I should flip them over with the driver close to the desk. Hmm, there is a thought since the desk runs corner to corner to corner along the wall (L-shaped).
The advantages of the Frugal Horn Mk III and this hybrid is that it can take a variety of different drivers and I like that. Many drivers (and I do not know if that applies to the FE127E) have considerable change in their paramters when the voice coil heats up resulting in changed behaviour in an enclosure. If the enclosure is accommodating different drivers then the changed parameters have no (or hardly) a noticeable effect. This is what has refrained me from making the PAWO in the past - only the FE127E seems to work properly in it (same as the hybrid FE126En horn which appears to be sensitive to driver selection).

Quick question on build. (I did not see a forum dedicated to building question.)
When you guys finish the kit, do you finish the individual pieces first, and then put it together - or do you assemble the speaker first and then finish it?
Thanks,
UL

This is the FH Mk1 thread, there is a build thread fro FH3.
Assemble 1st, then finish.

Hello,
a few years ago I build the original Frugal Horn MK1. It was the very first version I think. I still use my Frugals almost every day - and enjoy them for what they are. Anyway, two weeks ago a friend heard my Frugals and asked me if I could build him a pair. Sure, no problem I said - already bought the Fostex FE108ES for him. He can't wait to get his new speakers ;-) . But, here is my problem: I can't find the plans for the FH MK1 on my computer. Also, can't find them on the frugal-horn-website :-(.
Can anybody help me?
Thanks
Mike
