What is a good crossover frequency?
What is the recommended crossover frequency for a subwoofer.
For THX Certified and non THX Certified home theater systems, 80 Hz is the recommended setting.
However, you can set the crossover (LPF) between 80 Hz – 120 Hz based on which setting sounds best for your system..
What Should low pass be set 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.
Do subwoofer cables make a difference?
No, any RCA cable should work. Longer runs require better shielding, but there’s nothing special about the cable itself. Check out monoprice. And for those about to bring up true 75ohm, it won’t make a difference for subwoofers.
How do I hook up my LFE subwoofer?
For the signal, use a subwoofer cable to connect your receiver’s subwoofer output to the LFE (low frequency effect) input on the sub. Many stereo receivers and amps also have subwoofer outputs for these connections.
What is LFE setting on subwoofer?
LFE: This stands for Low Frequency Effect and is a the dedicated “. 1” channel in a 5.1 or 7.1 surround mix. … Both or LFE+Main: Most systems have a mode whereby the bass frequencies below the AV receiver’s crossover point are sent to both the subwoofer and the main speakers.
Is LFE digital or analog?
According to the standard, Dolby digital 5.1 consists of 5 audio channels plus one low band channel for Low Frequency Effects (LFE). The LFE channel provides low band audio below 120Hz as opposed to the full frequency of the 5 main channels. This is the same for 7.1, just the number or main channels are increased by 2.
Where do you place a subwoofer?
A subwoofer placed in the corner of a room may increase the subwoofer’s output – causing the sub to sound louder. Try placing your subwoofer in a corner and see how it sounds. However, depending on your floor space, a corner might not be a viable option for your subwoofer if it’s too far from your listening area.
What should LFE be set at?
The LPF for LFE is the low pass filter setting for the LFE channel. Normally this is set to 120 Hz, since that is typically the upper limit used by DVD mixing engineers.”
Should I use LFE subwoofer?
You should use the LFE/. 1 input any time a REL subwoofer is being used in a Home Theater system. The Subwoofer/LFE/. 1 output from the processor or receiver should be connected to the .
What phase should I set my subwoofer?
Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees. This will let you determine if the bass sounds louder in your seating position.
What should I set my subwoofer crossover to?
Tips for Setting the Proper Crossover Frequency of a SubwooferIf you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly.The most common crossover frequency recommended (and the THX standard) is 80 Hz.The numbers below highlight general guidelines for speaker/subwoofer crossover frequencies.More items…
Is a subwoofer cable just an RCA cable?
you can use a standard RCA cable, but a subwoofer cable is suggested as it has more shield in it and provides more clarity and resolution. a subwoofer cable comes with a standard RCA connector but is thicker than the standard RCA cable. … Any RCA cable will do. But go for a thicker cable for better signal transfer.
What should I set LPF for LFE?
This is the high frequency cutoff point for the LFE, also known as the . 1 channel in a 5.1/6.1/7.1 surround source. In practice this should always be set to 120Hz since the LFE channel supports information up to that frequency.
What is phase in subwoofer normal or reverse?
Normal – the subwoofer is ‘in-phase’ with the other speakers; ie when the other speakers move in, the subwoofer moves in and when the other speakers move out, the subwoofer moves out. Reverse – 180 degrees out of phase. The subwoofer moves in when the other speakers move out.
Why are there two inputs on my subwoofer?
Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.
Is 40 Hz low enough?
below 40 hz? yes, quite necessary. below 30 is where it gets less important. 30-45ish would be what most would consider real subbass….you may not hear it with a standard computer speaker setup, but you roll off anything below 50, there will be something noticeably missing on the dancefloor.
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.
Why subwoofer has left and right input?
The left and right channels are combined in an LFE cable to allow for a singular cable to evenly disperse the signals to the subwoofer. More than likely, you will use an LFE input cable for your subwoofer connections. … The LFE input in a subwoofer allows for this to be done simply through one standardized connection.
