The Frugel-Horn Project

[serenechaos]

imho it is very impotant to play a bit with the frugels until you get what you want. same is true with ron's austins.

hello robert,

no, i did not line the austins horn path with cork. at least not yet.

it was a general statement: i think you have to tweak a speaker until you get the exact sound you want to have. there is always room for improvement. i think that’s a huge advantage diy offers.

i did build the frugel and the austin at the same time. the austin sounded very good right from the start, but I guess there is still room for improvement. while my 108es is breaking in, i will tweak the austin’s. that said, i do not think that the austin’s benefit using cork like i did it with my frugels or like Tom Zurowski did it with his Zhorn http://www.audio-resolution.com/zhorn/herukamain.html.

with the frugels i noticed a “hollow midrange coloration”. Please allow me to quote Richard George from http://www.tnt-audio.com, who reviewed Horn Shoppes “The Horn”:

“Some coloration of emitted sound was noted. There seems to be two components of the coloration: the folded horn itself imparts a minor horn coloration to the lower mid-range and below - a weakly audible sound reminiscent of voice amplification using a simple bullhorn; and there appears to be minor phase distortion in some lower frequencies because the mouth of the horn is located on the back of the cabinet, facing the wall. In reality, while both effects are occasionally noticeable, they are not intrusive, and guest listeners did not identify either one.”

he is not talking about the Frugels of course, but the Frugels also have a coloration like this. i read his review after I build an noticed it with my Frugels.

after lining the last 50% or so from the horn path with cork, it was gone . thx to Tom Zurowski.

i can not hear a coloration like this when i am listening to music with my austins, so i do not think that cork is necessary. but who knows. maybe it would improve the sound.

i am sorry for my bad english. i am still going to school and have a lot more to learn.

regards

I think that your english is good enuff to teach some of the english-only speakers around here some tips

Just a heads up... the Frugel-Horn has out-grown its temporary space on the planet10-hifi site and will soon move to its own domain, where it will be joined by Scottmoose's Spawn family (and i hope a few others).

Thanks Mike,
I didn't see your post, I've been working on my Austins.
I'm building them out of baltic birch, and french polishing the insides(rubbing in shellac)--it seemed to help with some Nagaoka stuff I built before, maybe a good idea, maybe not?
I don't plan to change anything else other than doubling the side panels.
Thanks Ron & Dave for giving the community all these great designs!!!

I'm unfortunately hamstrung by the lack of a table saw to cut out the frugel parts (waiting for dem flat paks) but am greatly enjoying the family of observations and tweaks that are growing out of the project.

Keep it up, dudes...

I have often wondered how the sound would change if the inside surface of a horn path or a port tube were covered in dimples like on a golf ball.
