Cardioid dispersion
Cardioid dispersion avoids unwanted energy behind the system
and greatly reduces the excitation of the reverberant field at low
frequencies providing the greatest accuracy of low frequency
reproduction. The subwoofers can be used as stand-alone solutions
or in stacked combinations with a minimum distance of 60 cm (2 ft)
between adjacent cabinets or between the subwoofers and a side
wall. When positioned in front of walls, the minimum distance to
rear walls is maintained by the wheels mounted at the rear of the
cabinet.
2.2 Connections
The cabinets are fitted with a single NLT4 F connector using the pin
assignment 1+/1– for the front drivers and pins 2+/2– for the
rear driver.

NOTICE!
Risk of damage to the system components!
Different pin assignment on the loudspeaker and amplifier.
Þ
Please refer to the corresponding amplifier manual.
Cabinets with Phoenix option are fitted with a 4-pole Phoenix
connector socket (Type: DFK PC 4/4 GF) using the following pin
assignment:
▪ Pins 1+/2– feeding the forward LF drivers.
▪ Pins 3+/4– feeding the rear LF driver.
Phoenix specifications and recommendations
The cabinet comes with a Phoenix plug (Type: SPC 5/4 Push-in
spring connector) which is already connected to the corresponding
Phoenix socket of the cabinet.
The plug allows for direct wire connection without any tools
depending on the cross section and conductor structure.

d&b LoadMatch
With the d&b four channel amplifier platform, the LoadMatch
function enables the amplifier to electrically compensate for the
properties of the loudspeaker cable used without the need for an
additional sense wire. For applicable loudspeakers, LoadMatch is
therefore independent of the connector type used.
