QLight™ DP series
CONVERGING ELLIPTICAL WAVEGUIDES™
Adesign feature of the TQ-308DP, TQ-310DP and TQ-315DP loudspeakers is the Converging Elliptical Waveguide™ (CEW™). This gives many user advantages. The comparatively short flare length allows the HF and LF components to be physically aligned in the cabinet, so ensuring coherent arrival at the listener’s ear irrespective of distance from the loudspeaker. The elliptical format shapes the wavefront smoothly, and eliminates reflections in the throat area. Additionally this design does not suffer from the distortion typical of horns employing diffraction edges.
The waveguides can be removed and rotated through 90º in the cabinet, which allows the products to be installed in either vertical or horizontal formats while retaining the required coverage.
