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

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

The UPQ-D1 delivers an incredibly consistent polar response and a gentle coverage rolloff that evenly extends out to its 10 dB points of 100° by 60°. Thanks to meticulous research in Meyer Sound's anechoic chamber, the horn offers smooth and consistent performance, with a remarkably consistent beamwidth in both horizontal and vertical planes. It also provides uniform attenuation for all frequencies outside the specified beamwidth.

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

• Wood treatment: Before cabinet manufacturing, the raw wood gets a special treatment to penetrate and stabilize the wood fibers, enduring various temperatures and extreme humidity.
• Cabinet finishing: The assembled cabinets receive a highly impervious finish with a sealing primer and a finishing topcoat. Coatings are applied on both surfaces, one on the interior and two on the exterior. The final step is a two-part modified acrylic urethane similar to military applications.
• Driver treatment: All cone drivers are coated with a water-resistant sealant.
• Exterior protection: Grille frames are coated against corrosion, and all components mounting to the cabinet use custom gaskets and stainless steel fasteners.
• Removable rain hood: The rain hood shields connectors even in windy rain.

Features:

• • Wide horizontal pattern for broad listening areas and focused vertical pattern for precise coverage
• • Highly energy-efficient amplifier with advanced digital signal processing for flat amplitude and phase response, ensuring tonal accuracy and precise imaging
• • Integral stand mount and QuickFly mounting options for easy rigging
• • Constant-Q horn for uniform response across the coverage area
• • Exceptional size-to-power ratio for application flexibility
• • Consistent and predictable performance for accurate system design
