    For example, since the input (chassis) impedance of a single 650-P is 10 kOhms, cascading 20 650-Ps produces a balanced input impedance of 500 Ohms. If a 150 Ohm source is used, the 500 Ohm load results in a 2.28 dB loss.

  • Page 7 Placement One of the most important factors governing subwoofer response is their placement relative to adjacent sur- faces. Subwoofers gain significant power by coupling, or loading, with nearby floors and walls. Half-space loading describes a speaker coupling with one surface.
