Each LFT has five individual driver panels. The outside portion on each
panel is divided into separately driven bass and (line-source) midrange
areas, with the former operating from 400 Hz down, and the latter
operating from 400 Hz up to 10 kHz. The tweeters operate as a line source
from 10 kHz up to and beyond 20 kHz. The midrange and tweeter
sections are distinguishable by their thinner magnet structures.

All three panels operate as woofers, from 400 Hz on down. Actually, all of
the panels, including the “woofers,” are physically capable of operating to
beyond 20 kHz, but would exhibit undesirable diffraction effects and poor
dispersion if allowed to do so, which is why the panels are segmented into
different sections for different portions of the frequency range. The use of
a flat panel design maintains excellent phase response throughout the
audible range.
The LFT-6 can be made to operate at almost any impedance; our present
choice of a nominal 6-Ohm impedance has been made in the interest of
maximizing efficiency and amplifier compatibility. Because of the large
