What is LFE on a subwoofer?
The low-frequency effects (LFE) channel is a band-limited audio track that is used for reproducing deep and intense low-frequency sounds in the 3–120 Hz frequency range. This track is normally sent to a subwoofer—a loudspeaker designed to reproduce very low frequencies.
How do I connect my LFE subwoofer to my receiver?
Connect a subwoofer through the subwoofer output (SUB OUT or SUBWOOFER) of a receiver using an LFE cable. Connect using an RCA cable if there isn’t an LFE subwoofer output or LFE input. If the subwoofer features spring clips, use the speaker output of the receiver to hook it all up.
Is LFE the same as subwoofer out?
The difference between the LFE channel and the subwoofer output is that the LFE channel is used to carry additional bass information in the Dolby Digital program while the subwoofer output represents how some or all of the bass information will be reproduced.
Can you connect LFE to RCA?
Subwoofers often have inputs labelled “LFE” in addition to a set of L+R RCA inputs. If your sub has an “LFE” input, that’s what you connect to. If it doesn’t have an “LFE” input – which is the situation you face – you should be able to connect to either the L or R RCA input, or to both inputs (using a Y-splitter).
What is LPF for LFE?
The AVR subwoofer menu may also have setting called ‘LPF for LFE’. This controls the highest playback frequency for the LFE (. 1) channel before being cut-off (i.e., low-pass filtered) by the AVR.
What should I set my LPF subwoofer to?
As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.
Are Klipsch Reference subwoofers THX certified?
No. According to the Spec sheet, manual and Klipsch website, this speaker is not THX certified.
