Lens No.1896 for Fostex T96A

[@NakeanWickliff]

I love your horn designs. What are your thought in using large horns in open baffle designs? At that point they are no longer OB or dipole because the backs are closed. Right now I'm using a Markaudio Alpair-10P Paper Cone 6" Full Range driver as my upper range 300hz and up but I wonder if I'm missing out on some top end with this design. I had to boost the HF a lot to keep it from rolling off really early, but this design is dipole through and through. My thought was to keep the full range speaker but add a horn tweeter for the top end.

It seems hard to find DIY lenses or horns for compression drivers that have off axis data.

I started out by purchasing the B&C ME20 horn with the B&C DE120 and I got good results with the Fostex FF165WK 6.5 fullrange. It was a step up in soundstage width compared to running just the fullrange. After that I did a similar sized JMLC circular horn and I noticed better clarity. But I still missed the coherent point source quality. So fast forward ten years and I think the shallow horn No.1928 using the 3” Fostex FF85WK crosssed at 200Hz provides the best of everything. Soundstage, smoothness, everything. josephcrowe.com/blogs/news/shallow-horn-no-1928-with-fostex-ff85wk

Fascinating behavior off axis. Always been intrigued by these super-tweets ... and something I have zero experience with, ... despite being at this for decades.

They have a certain sound that’s unique which is why they are still around after all these years.
