WideLine Engineering
WideLine systems follow the classic high
performance hot rod formula: engineer
maximum horsepower into a package with
minimum size and weight. For transparent
high frequencies, they use a compression
driver with a 3" (75 mm) diaphragm and
neodymium magnet. For midrange punch
and low-frequency authority, a pair of
high-performance 16 ohm woofers – 8" (200
mm) cones in the WideLine-8 and 10"
(250 mm) woofers in the WideLine-10
are employed. For optimal overall amplifier
efficiency, in tri-amp mode the LF and MF
sections of up to eight enclosures can be
powered by a single two-channel amplifier.
WideLine Coverage
WideLine systems have exceptionally wide
140° horizontal coverage. They create a
broader stereo image, reduce the need for
supplemental fill speakers and give you
more placement options.

Two engineering achievements let WideLine systems cover more seats with fewer boxes. Covering high frequencies is QSC's patented multiple aperture diffraction slot waveguide. The waveguide exit extends nearly to the top and bottom of the enclosure, minimizing discontinuities between adjacent elements. This virtually eliminates destructive interference and creates a flexible, continuous acoustical source.
Both WideLine systems operate in 3-way mode. One woofer covers only the low frequencies while the other extends to the mid/high crossover point. The single midrange transducer keeps horizontal coverage as wide as possible and assures smooth response both on and off axis at the transition to the diffraction-slot-loaded high-frequency section.
Subwoofer Integration
Sound system designers and operators are increasingly flying subwoofers with the main array for a more seamless acoustical transition from low-mids to subbass. Both WideLine systems have arrayable subwoofer options. |

Intrinsic Correction™
Phenomena such as waveguide acoustical impedances and loudspeaker cone resonance gave every loudspeaker its own character – until now. QSC system engineers have harnessed digital FIR (Finite Impulse Response) filters to provide Intrinsic Correction of these "unavoidable" acoustical errors. Intrinsic Correction provides the most accurate acoustical magnitude, frequency and phase domain performance possible, giving WideLine systems excellent power response and extremely natural, uncolored sound. For flawless audio quality, operational simplicity and low cost, the QSC SC28 processor combines factory-programmed Intrinsic Correction tunings with user-adjustable system equalization, offset delays and output levels. For sophisticated, programmable DSP, Intrinsic Correction tunings are available for QSC BASIS™ processors. Thanks to Intrinsic Correction, WideLine arrays are totally responsive to any equalization you may apply as an adjustment for array configuration, acoustical conditions or individual preferences.
