Hi Peter,

While you're thinking about the Hedlunds, you might want to look at what Miroslav has created............ I'm impressed !!!

Wow!

Thanks for having dig up such a nice diamond. They are outstanding, the most beautiful Hedlund Horns I ever saw. Congratulations to the builder

First, I'd like to congratulate all the audiophiles that have built Hedlund horn-speakers. It's hard work!

You can take a look at the Hedlund speaker-plan over at Lowther's net-site (www.LowtherLoudspeakers.co.uk). Just look under "cabinets." Well, I did, and I noticed that Jan Hedlund (of Sweden) specified solid wood for the curved panels of the speaker. Believe me, this is the hard way to build those speakers: You are forced to make precision, odd-angle cuts on several parts! Even with a lifetime of woodworking experience, it is easy to make mistakes with those cuts!

Now, if you are contemplating this kind of project, I suggest that pick up an issue of Wooden Boat magazine and take a look the many examples of boats built with wood-veneers (esp. kayaks and canoes)! The boat-building process involved is called cold-molding. Below is a description of how it is done.

Cold-molding with West System epoxy:
In this technique, you use an Arrow T-32 Staple-Gun Tacker with 3/16" (or 1/4") thin-wire staples to temporarily fasten 1/16" wood-veneers to the ribs of the boat until the West System epoxy dries out. You keep adding plies until you reach the desired thickness. That's it, and it's easy!

Why 1/16" veneers? Well, 1/32" is the standard thickness for furniture. However, for boat-building, 1/32" takes too long--you go twice as fast with 1/16"! You might say: I'll go for 1/8" veneer to finish faster! Well, it doesn't work too well because 1/8" veneer doesn't bend as well as 1/16" veneer. Actually, the 1/8" thickness is considered wood, not veneer! So 1/16" is a must for curved panels, and 1/8" may be used for straight panels.

Personally, I went crazy searching for those thicknesses. Yes, Constantine's has them, but they don't specialize in these. So here is a source for 1/16" veneer and 1/8" wood:

Certainly Wood......tel (716) 655-0206
11753 Big Tree Road
Route 20A
East Aurora, NY 14052

Why West System epoxy? It's waterproof! Remember, moisture causes movement in wood. So epoxy eliminates that problem completely. Another plus is the superior strength of the bond between the plies of veneers--it will last an eternity! BTW, TAD-Pioneer uses epoxy to glue their wood horns.

Information on cold-molding:
I got my info from the March/April 1986 issue of Fine Woodworking magazine. "Cold Molded Cradle," an article by Larry Hendricks, explains the process in detail. I imagine you can also find info in Wooden Boat magazine. Or you can contact Taunton.com, the publishers of Woodworking magazine to inquire about cold-molding books.

I hope all this helps. Although I like the Hedlund, I'm really smitten by Carfrae's Little Big Horn (www.carfrae.com). Both are difficult to build. However, I have no doubts that cold-molding is the way to go!

My best regards to all, Gariver


 

Has anyone modified the Hedlund to accept "A" series drivers??, posted on April 28, 2000 at 13:09:22

How hard would this be if you are already thinking about building a pair??

I spent an afternoon listening to the Faircurves at Dave
Clark's (the DC in DC Audio) place last December. His demo
version was using the PM7C and was driven by an modified
(don't know how) SCA35. The sound was extremely good, and
I was able to hear the promise of a Lowther based system, but..
I'm not sure that the combination was able to extract the best
out of the cabinets. The highs were down in level with the
knee being fairly early, more so than I expected considering
everything I read about Lowther highs. This might be driver
related, maybe the difference between the PM7Cs and the PM2As?
The palpable uniqueness of a single ended signal was missing,
but I attribute that to the pp amp. The cabinets themselves
were gorgeous, and if I wanted to drop $5K on cabs, these would
be my first choice, assuming my wife would let me :)

My positive exposure to the Faircurves waw the push I needed to
buy the Welborne Moondog/Medallion kit. Someday I'll give the
Hedlunds a shot. They at least have a smaller footprint than the
Faircurves and would integrate into my living room easier. The Faircurves are big the bottom!

Take a look at the Autumn 99 issue of Listener Magazine. Art Dudley
reviewed the Faircurves quite favorably.
