Now, the volume control will raise and lower the volume for the subwoofers and the left and right speakers simultaneously. Additionally, the crossovers are now con- nected so that the crossover switches can be adjusted to your requirements. You must adjust the crossovers on each subwoofer with this
Optionally, a jumper of wire may be con- nected between the L+ and the R+; and between the L- and the

Very Large Subwoofer Array (VLSA)
Using four or more PSW8 subwoofers in a system creates a system of unprecedented clarity, with stunning bass impact and potentially extraordinary maximum vol- ume capability. Because of the extremely low impedance of a parallel VLSA system, multiple channel amplifiers are normally used to power them. Because of this, in- wall volume controls are incompatible with VLSA systems.
In a system of this type, it is recommended that the satellite speakers be driven full
range (or with an external electronic crossover) by a separate amplifier channel. Connections are

Connections to a VLSA are normally made from each PSW8 to a
Each PSW8 has a jumper installed to paral- lel the voice coils for maximum efficiency. (See Figure 6).
The crossover controls on each subwoofer affect only the subwoofer response. Level controls on the amplifiers facilitate blend- ing and compensation for placement.
Speaker Wire
For most applications, we recommend you use 16 or 18 gauge wire. For wiring runs longer than 80 feet we recommend 14 gauge wire. The no strip terminals of the PSW8 speakers will accommodate up to 12 gauge wire. When you run wire inside walls, special jacketing
