They're all my designs. I borrowed concepts from Nelson Pass for my Class A amplifier, and the Tapped Horn idea originated with an article from William Cowan's website.

I see William uses B&C drivers as well in his unity horn. That's encouraging!

Nice work Joseph, just had a look. I wonder if you could in fact try another diaphragm on your coaxials.

I suspect you can now that you mention it. The dome profile would have to be identical to match the phase plug. For the cost of a replacement diaphram kit it's worth a try.

Default 12" Coaxial project, further mods

I've updated my blog with further improvements to this project, namely removing the dust cap from the coaxial and adding treatment to the horn throat exit. I'll post some FR measurements tonight. Also, I've mounted the driver to some 1/2" fibrous rope to decouple from the enclosure.
