Waveguides and horns

[AlanElsdon]

Two questions, firstly what has happened to the DIY page on the Horns.pl website, I cannot find a way to it?
Secondly what (if any) are the recommended drive units for the Tractrix 110?

Website will be split into:

1) Horns - complete speakers
2) horns-diy.pl - horns

 

[AlanElsdon]

Thanks for the new link - I will wait for it to be ready.

Any measurements on the Bi-Radial horns?

Are the dimensions stated on the Autotech DIY page correct?

2" version: Width: 565mm, height: 366mm, depth 377mm
1,4" version: Width: 755mm, height: 360mm , depth 480mm
1" version: Widhth 605mm, height: 360mm, depth 385mm.

I mean why is the 2" version the smallest of the three? Why is the 1.4" significantly larger vs the other two?

Hello, I received my Iwata-300s - beautiful horns
I have jbl2447's and 1.5-2" adapters, should I be concerned about throat angle changes?
I'll try to use these with Klipschorns or Klipsch La Scala's
how low can i crossover these horns?
I've been using various horn /driver combinations - I have been enjoying altec511a's with jbl2470 + jbl2404
Most importantly: how can I get my wife to appreciate this wonderful quest for audio nirvana?

Dimensions are correct - client's requirements

Great looking pair of loudspeakers! They definitely qualify as eye candy. I bet they sound good too!!

@ jzagaja

Wow, did you make those yourself? Is that rosewood?

 

[jzagaja]

No no My friend professional carpenter - not easy even for him
This is modified rosewood and plywood (top and bottom side of horn), ICA lacquer.

Impressive work! I wish I was capable enough to build a SEOS horn with my Festool setup.

 

[Studio Au]

Almost anything can be made with Festool!

Ive been constructing an mft, router table table especially to be able to make conical, compound turned horns...

Aluminium Radian 950 in TH-4001 type horn (see previous posts) compared to Beryllium version in JMLC horn.

Would be nice to see Beryllium v's Aluminium in same horn

I have been running 4 inch Truextent beryllium diaphragms in my JBL 2446 CDs for the last couple of years. They work great! As recent as last week I was exchanging emails with Al at USSpeaker.com He tells me that US Speaker can supply Radian brand CDs with beryllium diaphragms loaded in them for a reasonable price.

That's good to hear Carl. I'll more than likely be ordering from them as I've had good experiences with them in the past.

Hand made by my friend with Festool tools. Interchangeable front plate, configuration: Radian 950 and Beyma 15B100R-GH.

Whats the frequency response on one of those, and what does it take to get a pair.

 

[jzagaja]

This is a raw frequency response off axis.
