CONNECTIONS
Connections and system matching
Check the inputs and outputs against the equipment you already use. If you have a connection question, send us the model names or a photograph of the sockets.
Connecting and setting up
- Connect the AV receiver or processor’s subwoofer output to the RCA LFE input. The RCA output can pass the signal to another subwoofer.
- The cabinet has no physical High Level input. Set the receiver’s crossover, level and delay to suit the main speakers.
Points to consider
- The quoted low-frequency extension is a manufacturer specification. Bass level and decay at your seat also depend on placement and the room.
INSTALLATION
Placement and installation
- Leave room around the cabinet and rear connections, keep ventilation openings clear and the mains plug accessible. Compare bass at the main seats when setting crossover, level and delay. This model is not designed for vertical stacking.
