Hi jzagaja,

Is there any plan on doing TH4001 (or possibly TH4003) clones one day?
Also, have the biradials already been built or do they only exist as simulations?

Another question, which I am sure have already been addressed in the past (sorry about that ):
Have measurements or simulations been done on the effect of damping layers (bitumen like) on the rear of your waveguides?

We don't have TH4001 so we can't clone. Biradial is close and I'm waiting for samples. Already you can order Biradials.

Not yet - if you have good candidate I can try.

Thanks to generous Mr. C.J. Struck (Tymphany head engineer) I've got impedance autosequences used for example by Beyma in their datasheets. My main program is old thus autosequences don't work properly (problem with scale factor). nevertheless plots are ok except reference level. Comparison with LIMP (m-audio Transit USB), transducer is small BMR - one sample is good and another is broken.

Iwata 600 above a cabinet top chamfered like the Orphean MKII, to allow a reduction in c-c spacing. Just a little while longer...

Hey mate if this is a request page for dream horns well I want a pair of goto S300b and S150 B for soo long but cant afford to raise the money for even the S150. I want to make an adapter and use vintage standard a1/3/8 inch threaded drivers of so many types to be had for 100$ a pair of less with simple phasings and phenolic diaphragms. Drivers that need real slow openings that will go real low down too. I don't need to break any copy rites I just want similar sized expo horns with standard 1/1/38" threaded sockets. All these modern fast opening flares might great for modern style drivers but older drivers with smaller diaphragm sises that with the right expo horn get go very low and with a warmer tone. So how about some long expos.? There is not one in the catalog. Just a 1 3/8" to 8 inch expo adapter would be golden man. Easy to make and ship. Any Diyer can go from there. PLEASE! And then a 2inch version too!
