Great pun!

Cheers Ked. One of my all time favourite jazz albums and the pnoes are doing it brilliantly, crazy jealous of Bill’s and the Generals setups! So many things going so right… for me these are among the most ideal recipes for a full on amazing! I do find these approaches to the mystical and most musical analogue arts very inspirational.

Thanks Ked for keeping us up to date on Audiophile Bill’s system; it’s greatly appreciated! I miss his contributions to the forum.

Great, thanks Ked. What's up with the three mini horns on the floor in Bill's new setup??

 

[Solypsa]

And are the subs there?

those are just display, the ones he made. He might use the big one as part of a future DIY build

 

[bonzo75]

And are the Devor 30's there?

he still has the subs he made yes but not in use here

4001 is not particularly relaxed...on the contrary a litt squeeky on certain mid freqs around 3-4K and does break up rather early and need to be tamed by the TH-4001 fins or low-passed at max 8K. The fins create other problems

Might this driver be a good match for the TH4001 horn?

I only have the Radian 760 Be 3" diaphragm, but would the JBL2450J 4" diaphragm be a way better match with that horn?

I’d try the Radian
With the JBL you’d need a tweeter, which is kind of a point to not have in addition to the lenses in TH4001

By lenses, do you mean the vanes?

It's sort of like a constant directivity horn, at least in horizontal plane, as shown in this polar chart.

Any downsides to using the TH4001 for a two-way system above my Altec midwoofers?

Altec 416-8B in 100L Sealed

In this blog post I test the Altec 416-8B in a 100L sealed enclosure. Testing was done outdoors for the frequency response and then brought indoors for the distortion testing. The woofers are new from Great Planes Audio. A customer has sent me the finished cabinets with drivers to integrate...

I hope to be able to hear Nicolas Badey's Next Gen Biradial and that X-shaped horn too by end of May. https://audiohorn.net/x-shape-horn/

Curiously, Nicolas says he doesn't like Radian drivers. "Phase plugs are outdated" (??)
