TQ-315DP self-powered two way loudspeaker
The TQ-315DP offers full range response and the highest performance from a two-way
loudspeaker. The integrated Class D amplifiers and DSP ensure an optimum match between
amplifiers and drive units, providing a convenient and easily transportable package.
It incorporates a 15” LF driver and a 1.4” exit (3” diaphragm) compression driver on an 80° x 50°
Converging Elliptical Waveguide in an optimally ported trapezoidal enclosure.
All connections and operating controls are located on a recessed panel at the rear of the cabinet,
including gain trim, low frequency contour, power switch and status LED’s. The loudspeaker
accepts a balanced input from an audio mixer on a 3-pin XLR, and a parallel link connection is
provided to connect to additional powered loudspeakers. The power supply is auto-sensing, which
allows the TQ-308DP to be connected to mains supplies ranging from 100 volts to 230 volts AC.
The module is fully field-serviceable simply by removing four bolts and a multi-pin connector. An
RS232 data port is provided to enable firmware upgrades.
TQ-445DP self-powered three-way loudspeaker
The TQ-445DP is a compact three-way self-powered full range enclosure including integral Class D
power amplifiers and digital signal processing. The use of Class D power amplifier technology
ensures an exact match between amplifier and speaker for optimum acoustic output, and offers
exceptional ease of use by combining the entire electro-acoustic system in one convenient, easily
transportable physical package with negligible additions to the cabinet weight.
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 TQ-445DP 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-425DP subwoofer
is recommended.
