Meyer Sound UPQ-D3 Large Point-Source Loudspeaker with 5-Pin XLR

The UPQ-D3 offers an extremely consistent polar response and a gentle coverage rolloff that extends uniformly out to its ‑10 dB points of 100° by 100°. The horn’s smooth and consistent performance is the result of meticulous research in Meyer Sound’s anechoic chamber, and it exhibits a remarkably consistent beamwidth in both the horizontal and vertical planes. The UPQ‑D3 horn also delivers uniform attenuation for all frequencies outside the specified beamwidth.

Features:

• Wide horizontal pattern covers broad listening areas and focused vertical pattern allows precise coverage
• Highly energy efficient amplifier with sophisticated digital signal processing that provides extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging
• Integral stand mount and QuickFly mounting options facilitate rigging
• Constant-Q horn affords uniform response throughout coverage area
• Exceptional size to power ratio provides application flexibility
• Consistent and predictable performance ensures accurate system design
