The UPJ-1P provides full bandwidth frequency response down to 66 Hz, but if you need more low-frequency energy, Meyer Sound subwoofers such as the USW-1P can achieve frequency response down to 32 Hz, extending system response appreciably and increasing the acoustic power of a system in the lowest frequencies. UPJ-1P loudspeakers and subwoofers can be easily daisy-chained using the loop feature on the user panel. The individual loudspeakers will utilize their internal crossovers to appropriately divide the full-range signal. 

For most applications, a ratio of two UPJ-1P loudspeakers to each subwoofer will yield effective, balanced results in frequency response and headroom. The ideal ratio of UPJ-1P loudspeakers to subwoofers depends on the configuration of the system, the application, and the frequency content of the signal being reproduced.

In addition, Meyer Sound's line drivers – LD-1A or LD-2 – can be used to drive a UPJ-1P system with subwoofers. The line driver's filters will flatten overall frequency response and provide extra headroom. The UPJ-1P loudspeakers in the system receive their signal following a high-pass filter, while the subwoofers apply their normal internal crossover frequencies to a full-range signal.
