UPQ : Components

The UPQ loudspeaker is a two-way, bi-amplified system featuring drivers designed and manufactured at Meyer Sound’s Berkeley, California factory. Low-Frequency Section The low section features a high-power 15-inch cone driver with a 4-inch voice coil, created to meet the power requirements of the system. The drivers are a proprietary design employing neodymium magnets for higher efficiency and power handling with reduced weight.	Front View of Low Driver	Rear View of Low Driver
High-Frequency Section The high-frequency section uses a 1.5-inch exit, 4-inch diaphragm compression driver with a neodymium magnet powered by a dedicated amplifier channel. The output of the high frequency driver is coupled to a constant-Q horn. The smooth and consistent performance of the UPQ horn is the result of meticulous research in Meyer Sound's anechoic chamber. The horn exhibits a remarkably consistent beamwidth in both the horizontal and vertical planes across a wide frequency range of 1 kHz to 18 kHz and delivers uniform attenuation for all frequencies outside the specified beamwidth.

The UPQ-1P horn provides 80-degree horizontal by 50-degree vertical coverage (-6 dB points), and a gentle coverage rolloff that extends uniformly out to its -10 dB points of 100 by 60 degrees. The UPQ-2P horn is distinguished by a narrow coverage beamwidth (50-degree by 50-degree) that yields precise coverage and minimal interaction with walls and neighboring loudspeakers in arrays.
