Product Summary
The TQ-440SP is a compact three-way sel f-powered full range enclosure including integral power
amplifiers and contr ol electronics. The use of active power amplifier t echnology ensures an exact
match between amplifier and speaker for optimum acoust ic output, and offers exceptional ease of
use by combining the entire el ectro-acoustic system in one convenient, easily transportable
physical package.
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 disperion waveguide, l oaded 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 com pression driver-based designs. In addition the 6.5"
mid-range driver i s a highly efficient device, and is able to handle large amounts of amplifier
power. The remaining high frequencies above 8kHz are effort lessly handled by a 1" compression
driver, operating in a relatively narrow pass band, and therefore subjected to m inimal 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 TQ440SP is able to offer higher SPL, significantly lower distortion, and unsurpassed vocal projection
capabilities in an equivalently sized physical package.

A rear panel switch selects optimised profiles for speech or music applications, enabling real
flexibility of use.
The TQ-440SP 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 fr equency
range of the loudspeaker by a fur ther octave the use of the complem entary TQ-425SP subwoofer is
recommended.
