user manual QLight series 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 wavegui

user manual QLight series System Requirements The TQ-440 is a bi-amped loudspeaker system. It requires two independent amplifier channels: one channel to power the low frequency driver (LF) plus another channel to power the midrange (MF) and high frequency (HF) together. A frequency dividing network is also required to split the signal and feed it to the appropriate driver section; the LMS-D6 digital loudspeaker management system or the LMS-A6 loudspeaker management system is recommen

user manual QLight series Equalisation Because the TQ-440 features a smooth and even frequency response, it does not need equalisation or correction to overcome the deficiencies often found in lesser designs. Should extended frequency response be required at more than medium sound pressure levels, the use of the complementary TQ-425 subwoofer is strongly recommended. In order to to compensate for the room acoustics, the TQ-440 requires only minimal equalisation. As in any system, ove

With the high dynamic range capability and low power compression of the TQ-440 you should find this wide angle arrangement adequate for all but the most demanding long throw requirements. It also has the advantage of needing fewer cabinets to cover the required area. When speakers are mounted together in close proximity ei

user manual QLight series Choosing the best location It was stated earlier that the TQ-440’s tightly controlled directivity gives it essentially point and shoot qualities. Every room has its own unique set of characteristics that affect any sound introduced into the room. These include reverberation reflections and decay time, sound absorption of materials used, temperature and humidity, etc. A degree of experimentation with different locations (if possible) is best, especially if you
