Subwoofers do not require any specific form of audio cabling. The specific type of cable needed to connect a subwoofer to an audio system will depend on the audio input jacks built onto the subwoofer itself.
for instance, Can you use RCA for LFE?
To utilise the LFE channel in the correct manner would mean that you connect a single cable to the LFE input on the subwoofer. … In almost all cases, a single RCA subwoofer cable would be the correct choice for your home theatre system.
significantly, Can I use a coaxial cable for a subwoofer?
Subwoofer cables and other RCA audio interconnects have no defined characteristic impedance. OTOH, 75ohm coax will work. Any coax will do. It is analog regardless of the cable used.
also What is RCA cable for subwoofer?
An RCA cable connects a subwoofer to a receiver with an audio signal sent to the standard left, right, and center channels with a coaxial connection. A subwoofer cable typically contains the same wiring but has additional shielding added to reduce the speaker hum and provide greater sound clarity.
Why does my subwoofer have 2 inputs? Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. … By using both inputs with the same mono signal doubles the subwoofer sensitivity. This means that there is now only half the signal strength to drive it to full output.

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.”
What should LPF for LFE be set at?
In practice this should always be set to 120Hz since the LFE channel supports information up to that frequency. When you set this lower than 120Hz the receiver or preamp will not redirect the LFE information to other channels.
What is LFE on my subwoofer?
LFE (Low Frequency Effect) – The discrete content sent to the subwoofer from a Dolby or DTS encoded audio track. ( The .1 in a 5.1 or 7.1 audio track) LFE + Main – The low frequencies output to the Subwoofer whether the speaker channels are set to Large or Small.
Is RG6 good for subwoofer?
Monoprice RG6/U cables are great for those that want good quality and don’t want to break the bank. … I typically use RG6/U for subwoofer and Digital Coax connections, but these can be used anywhere you use a standard RCA type cable.
Do subwoofer cables make a difference?
But, will a subwoofer cable matter or make a difference? Subwoofer cables do matter as they enhance sound quality through increased shielding added to the cable that serves to improve the analog signal sent through the wires and reduce audio hum that would otherwise be produced.
How long can you run a subwoofer cable?
A Not completely. While you could connect a subwoofer to your receiver using a coaxial cable longer than 20 feet and not experience problems, an RCA cable run that long is susceptible to electromagnetic interference (EMI) — especially if it crosses household electrical wires.
Is a subwoofer cable the same as a coaxial?
You can use the Coax digital cable for a subwoofer connection without problem. Digital coax cables and all video cables have a standard impedance of 75 ohms. They’re fully interchangeable. Other cables with RCA connectors meant for audio, including that subwoofer cable, may or may not have 75 ohms impedance.
What is subwoofer LFE?
LFE (Low Frequency Effect) – The discrete content sent to the subwoofer from a Dolby or DTS encoded audio track. ( The .1 in a 5.1 or 7.1 audio track) LFE + Main – The low frequencies output to the Subwoofer whether the speaker channels are set to Large or Small.
What cables do you need for a subwoofer?
If your subwoofer doesn’t have an internal amplifier, you’ll definitely want to connect an amplifier to it. To do this, you’ll need your subwoofer, an amplifier, at least one set of RCA cables (these are the red, white, and yellow jacks on a single cable), speakers, and speaker wires.
Does a sub need left and right inputs?
Hooking Up Your Subwoofer
Most subwoofers have both a left & right input. It usually doesn’t matter which one you use. Some people will buy a “Y adapter” or “splitter” so that a single cable can feed both subwoofer inputs.
What is LFE on subwoofer?
LFE (Low Frequency Effect) – The discrete content sent to the subwoofer from a Dolby or DTS encoded audio track. ( The .1 in a 5.1 or 7.1 audio track) LFE + Main – The low frequencies output to the Subwoofer whether the speaker channels are set to Large or Small.
Why do subwoofers have speaker inputs?
In this configuration, you probably have line-level input (RCA jacks) or an optical cable or HDMI digital input going into the subwoofer box. The electronics in the subwoofer box decodes the signal, generates low-freq and hi-freq signals for the subwoofer and satellite, and amplifies them to speaker level.
What Hz is best for bass?
Bass: 60 to 250 Hz
The fundamental notes of rhythm are centered on this area. Most bass signals in modern music tracks lie around the 90-200 Hz area. The frequencies around 250 Hz can add a feeling of warmth to the bass without loss of definition. Too much boost in the bass region tends to make the music sound boomy.
What is the best crossover frequency for a subwoofer?
Recommended Crossover Frequencies
- Subwoofers: 70-80 Hz (low pass), the most essential purpose of a subwoofer crossover is to block midrange sounds.
- Car main speakers: 50-60 Hz, the most critical element in main speaker crossovers is to block low-end bass (frequencies 80 Hz and below)
- 2-way speakers: 3-3.5 kHz (high pass)
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 low pass filter be set at for subwoofer?
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.
What is subwoofer LPF for LFE?
The LPF of LFE allows the sub to kick in a little a the higher frequency setting (100-120hz depending on what you set it at) so that it compensates for this roll off.
Where do you connect the LFE subwoofer?
Connect Using the LFE Subwoofer Output
The preferred method of connecting a subwoofer is through the subwoofer output (labeled SUB OUT or SUBWOOFER) of a receiver using an LFE (Low-Frequency Effects) cable. Almost all home theater receivers and processors and some stereo receivers have this type of subwoofer output.
What phase should my subwoofer be on?
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 does the crossover do on a subwoofer?
Crossover is the frequency where speakers begin to roll off, and the subwoofer starts outputting bass notes and LFEs. Most of today’s systems have an EQ feature that will set up the proper crossover automatically based on the specifications of your speakers.
