Is anyone familiar with Infinity Slope brand speakers?

Hello everyone. This post is a bit old but perhaps some of you are still monitoring it. I acquired a pair of Infinite Slope speakers yesterday that are a totally unknown model from what I can tell. They are not .6s, not Model 1 or Model 2 and in fact are about a third the size of the .6 speakers (I have owned or still own all those models).  These speakers are 18" high and 11" across.

The drivers are definitely Infinite Slope issue, the cabinet construction and rounding of the corners matches my Model 2A speakers. Other than the badge on the front no other identifying marks. I will try to post a picture of two, and if anyone has any thoughts on it that would be appreciated. I understand that JSE did some one-off speakers from time to time that were not well documented.

The best speakers I've ever heard in a home system were owned by my dentist (who owned a large 50's style California Ranch and had his practice on his lower level)  ....... A pair of "Infinite Slope" speakers that were as high and almost as wide as a refrigerator...... I think he paid $14,000 for them (in 1985 Dollars) and bought them from the famous "Lyric Audio" in NYC.(https://www.lyricusa.com/ !!!!

I quite well understand the  value of high order crossover slopes.  My tri-amplified DIY horn speakers use DEQX managed 96 dB/octave slopes for all crossovers.  The result is good.
