Hi Herman,
I have had many JBL's and always wanted a set with 15' woofers.
I know this is a JBL thread but I just bought some ME Geithan RL901K after having JBL/Revel for the last 20 years
They may have the properties you want plus more
Coaxial
16" in woofer and flat to 25hz
Cardiod bass response which means they are not as sensitive to placement especially in small rooms
Active
100% Analog
Relatively small size for a 16" speaker due to the coaxial arrangement of the tweeter & midrange
