Meyer Sound UPQ-1P With Flight Case in good condition. Some expected minor ware, in excellent working condition.
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 roll off 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 beam width 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 beam width.

The UPQ‑1P also provides extremely high power output with low distortion in a compact, vented two‑way enclosure. In addition to the constant‑Q horn, the loudspeaker features a low frequency 15‑inch neodymium magnet cone driver and 4‑inch diaphragm compression driver.
