DIY MDF tractrix horns and frontloaded horn systems

[Angelo888]

hi

my name is Angelo. I am swiss/italian, but live for more than 10 Years in brazil. Two years ago i started to dedicate myself more to Audio, and last year i started to design and build hornspeakers, and horns, made of MDF. To make these, i built a big wood lathe. With it i can turn horns up to one meter diameter.

here a link to my foto blog :

at the moment i am finishing to build for myself a 4way full frontloaded hornsystem, that can be seen also on my blog. My intend is to make my realisations also available for others,the horns, and also complete hornspeaker systems. For this purpose, i am working on a homepage. a forum, dedicated exclusively to horns, is up for one week now. I invite you to visit it and participate :

Beautiful workmanship on those. I have always dreamed of being able to "turn" an MDF horn. The closet I've come is my home built 7 foot folded bass horns, with the 15" driver acting as a direct radiator.

If he ever decides to post here (he has registered but just seems to want to lurk)...

I don't know what his problem is because he's not exactly 'shy' on Wigwam

Love those ones:

Those cab's took more than 5 month , and over 250h of work, to be built. That's why i think i will hardly make a second pair for commerce. Too much work on these. The horns are Orpheans from BD-design. They have been replaced with own horns, made with MDF, and using a Radian 950pb compression driver, from 300hz up. Crossing is too low, the horn should be bigger than 20", to reproduce the lower midrange frequencies with best results. It sounds much better with the 25" horns. On them, lower midrange was absolutely wonderful,, speed, dynamics and soundstage are simply breath taking. The best i got so far. These speakers will be replaced soon with the big 4way frontloaded horn system, which is beeing built right now. It is taking also a LOT of work to make it, too. Almost 3 month working on this system, and it will be finished probably in about one month, or so.
