3. nominal dispersion waveguide loaded with a TurboMid device The exclusive use of cone transducers in both the low and mid frequency bands produces a seamless transition at the crossover frequency with the result that all of the critical vocal range right up to 8kHz is lower in distortion than compression driver based designs In addition the 6 5 mid range driver is a highly efficient device and is able to handle large amounts of amplifier power The remaining high frequencies above 8kHz are effortlessly handled by a 1 compression driver operating in a relatively narrow pass band and therefore subjected to minimal mechanical stress The mid and high components are physically time aligned within the enclosure ensuring perfect time arrival at the listener s ear When compared to conventional two way designs the TQ 440 is able to offer higher SPL significantly lower distortion and unsurpassed vocal projection capabilities in an equivalently sized physical package The TQ 440 is designed for use with the LMS D6 digital loudspeaket management system which provides model specific crossover and limiting functions The TQ 440 is a full range loudspeaker and used by itself will provide high quality audio for all speech and many music reproduction applications In order to extend the effective bass frequency range of the loudspeaker by a further octave the use of the complementary TQ 425 subwoofer is recommended TQ 440 manual page 5 u
