Product Summary
The TQ-440 is a compact three-way bi-amped full range enclosure that offers uprecendented levels of audio clarity and definition.
It incorporates a custom-designed co-axial 12"/1" combination LF/HF driver in an optimally tuned vented trapezoidal enclosure handling the low and high frequency bands. The critical mid-range frequencies are handled by a proprietary 6.5" cone transducer on a 60° horizontal by 40° vertical 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.
