Subwoofer Placement

Your Deﬁnitive Technology subwoofer has been designed to operate at frequencies generally below 150 Hz. Because low-frequency infor- mation in this range essentially is non-directional, your subwoofer can be located anywhere in your listening room that is most convenient. Also, the continuously variable low pass ﬁlter operates at a very fast roll-off, ensuring great performance wherever you place your subwoofer. There are, however, some general rules that you should bear in mind when locating your subwoofer:

1.For maximum output the subwoofer should be placed in a corner or against the wall.

2.Corner placement will increase the subwoofer’s efﬁciency, which in turn will increase your system’s maximum output and improve the dynamic capability of the subwoofer.

3.While one Deﬁnitive Technology subwoofer will always sound great, the use of two subwoofers will deﬁnitely enhance your system’s performance by providing a smoother and more consistent response pattern. Here, it is recommended that you locate the subwoofers on the same side of the room as the main speaker of the same channel (if you are feeding them discrete left and right channel signals).

4.When using the ProSub with Deﬁnitive ProMonitors, consult the ProMonitor instruction manual for other placement tips.

Low Level LFE Connections

Most new model receivers, preamps and decoders feature a mono (line level) output intended to be used with subwoofers. This is the simplest connection method to use. You can feed the mono or LFE subwoofer output of your receiver or decoder to the LFE low level input on the subwoofer and achieve full performance. Usually, if your receiver or decoder already has a built-in low pass crossover, you should turn the low pass control on your ProSub to 150. Also, these subwoofer outputs tend to have less gain than main line level outputs, thus the gain control on your subwoofer may need to be adjusted accordingly for proper balance. Use the LFE input on the subwoofer to hook the sub- woofer up to the LFE (low frequency effects) output on Dolby Digital AC-3*decoders, receivers, etc.
