Meyer Sound UPQ-D1 Large Point-Source Loudspeaker with Weather Protection and 3-Pin XLR

The UPQ-D1 offers an extremely consistent polar response and a gentle coverage rolloff that extends uniformly out to its ‑10 dB points of 100° by 60°. 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‑D1 horn also delivers uniform attenuation for all frequencies outside the specified beamwidth.

Standard Weather Protection
Meyer Sound designs toward an IP rating of IPX4 (see “IP Ratings” on page 37) for Standard Weather Protection, which includes the following components:

• Wood treatment—Prior to cabinet manufacturing, the raw wood receives a special treatment that penetrates and stabilizes the wood fibers to withstand a wide range of temperatures and exposure to extreme humidity.
• Cabinet finishing—The assembled cabinets receive a highly impervious finish that includes a sealing primer and a finishing topcoat. The coatings are applied on both surfaces, with one coat on the interior and two on the exterior. The final step is a two-part modified acrylic urethane similar to that used in military applications.
• Driver treatment—All cone drivers are coated with a water-resistant sealant.
• Exterior protection—Grille frames are coated to resist corrosion, and all components that mount to the cabinet use custom gaskets and stainless steel fasteners.
• Removable rain hood—The rain hood is designed to shield connectors even in wind-driven rain.

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
