Hello uncledemp -
Sorry for the delay of 7 years, 5 months, but just saw your post.
I am in Fort Smith, AR and own a pair of Kienker Neel KNI-240 floor-standing loudspeakers. Serial numbers are 8628103 and 8628104. They are still ass-kicking speakers with 8 inch woofer and small tweeter below. Ported cabinets allow the low frequencies to be reproduced quite well.
I work in manufacturing, and if my serial number knowledge holds true, these speakers were built in the 28th week (July) of 1986. 103rd and 104th product completed that week.
My wife's sister bought them new and we acquired them around 2000. So these things are 36 years old and still pounding away to music like Thunderstruck! Hahaha! They are built incredibly robust and it's too bad the company is no longer around. I cannot find anything about the company whatsoever.
You can still buy some awesome Arkansas built speakers with a thick wallet. Klipsch still makes their high end loudspeakers in Hope, AR. I was in the plant in 2007; all handmade with very little mechanization. I'm sure it isn't too different today.
I'll post again if I find anything at all about the Kienker Neel company.
