Meyer Sound UPQ-1P Powered Loudspeaker

The UPQ‑1P self‑powered wide coverage loudspeaker offers an extremely consistent polar response, and is distinguished by its constant‑Q horn that 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 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 across a wide  frequency  range  of  1  kHz  to  18  kHz. In  addition,  the  UPQ‑1P  horn  delivers uniform  attenuation  for  all  frequencies outside the specified beamwidth.

Features:

• Wide, symmetrical pattern covers broad listening areas
• Extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging
• Integral pole mount and quick and easy QuickFly mounting options
• Constant-Q horn affords uniform response throughout coverage area
• Exceptional size to power ratio
