Has any one heard of a speaker brand ehT(Enhanced Home Technologies)

I am looking for information on some rectangular 5 way (2 tweeters 1 mid range and 2 woofers) Ceiling/Wall speakers that were donated to our nonprofit 
The company name is ehT (Enhanced Home Technologies) and the model number is P555LCR 
At some point this company was based in Scottsdale, AZ.
