How to connect a polk subwoofer

Subwoofers are primarily intended to improve the audio quality of your sound system. they anticipate and recreate low-frequency sound and let you enjoy incredible audio from your home theater system. Compared to most speakers, subwoofers can improve audio considerably more. You’ll need an audio or even video receiver and some speakers to add the woofer to your home theater. A very important component is the correct connection of the subwoofer to the receiving system.

This article describes how to link a subwoofer through a sub out or lfe out of a receiver or amplifier to a receiver or amplifier or through rca or speaker wire connections from a subwoofer. the steps and guidelines are well laid out to help you follow step by step to achieve quality sound.

Apart from the methods, this article also contains some general knowledge about subwoofer connection. In case you need more knowledge about this connection, there are answers to frequently asked questions. so please follow the steps and methods carefully to get all the basics of subwoofer connection.

methods to connect a subwoofer without subwoofer output to a receiver

Connect Subwoofer Without Subwoofer Output

1. place the speakers to the “left” or “right”.

first, learn how to manage your av recipient’s bass. To accomplish this, set all center, rear, and main speakers (both left and front) to either the large group or the small group depending on their output capabilities. then follow the manufacturer’s guidelines for more information on bass management methods.

however, all speaker sets, from small to large, are generally recommended. For best performance place all speakers equally and use an 80hz crossover. when you place the front and left speakers in smaller positions, the subwoofers work fine. even with two-channel sounds, this is effective. however, when the main speakers are tuned to the big pattern, things are likely to be quite difficult.

2. put the “main + lfe” on your satellite

This technique is successful when you place the speakers to your right and left. then look on your receiver for the subwoofer setting. Your AC receiver’s “bypass” feature helps you understand when and how your subwoofer is performing. then set ‘mains + lfe’ so your subwoofer can play when the headers are set to large.

There are also several bass management receivers for two channels. they give you separate settings for crossover, speed increase and decrease levels, etc. you can also select whether or not you need the subwoofer to drive two-channel audio sources.

3. use the output preamplifier

You can still link a subwoofer to the subwoofer if your receiver doesn’t have a subwoofer output. First, check on the rear panel of your receiver to see if the preamp output is available or not. it is usually labeled “pre-exit”.

when you find the pre out, use some interconnects between the receiver and your subwoofer. For example, if you only have one RCA input, connect a Y adapter to your subwoofer with one male RCA on one lock and two female RCAs on the other lock.

4. use speaker wires to connect the subwoofer to the receiver

again, your receiver does not have a preamp output; you can use your subwoofer as a speaker. To connect your subwoofer to the receiver, run the speaker cables. connect it to the receiver’s front left and right speaker connections. then connect the left and right headers to the speaker connector of the subwoofer. Subwoofers on the market generally come with speaker capabilities. still, before you buy yours, you should check it out.

A subwoofer can change low note sounds that loudspeakers can’t. you can feel the music as an atmosphere in your chest. connect the woofer to your home theater system and enjoy incredible quality sound. follow the steps here to connect your receiver to the subwoofer without a secondary output system.

frequently asked questions

1. how can I connect the subwoofer lfe output?

The recommended way to connect a subwoofer is via an LFE (Low Frequency Effects) cable from the subwoofer’s output (designated “sub out” or “subwoofer”). Almost all home theater receivers (or processors) and some audio receivers have this type of subwoofer output. the lfe ports are a specific output for subwoofers only; they are still marked as ‘subwoofer’ but not as lfe.

5.1 channel audio, eg dvd or tv, includes one channel output with the bass content of the channel which a subwoofer reproduces well. To set this up, connect the LFE or Subwoofer Out jack to the Line In or LFE In jack to the Subwoofer on the receiver/amplifier. normally there is only one cable that has single rca connections on each end.

2. how can I connect stereo rca or voice level outputs?

Sometimes you find that the lfe woofer output of your receivers or amplifier is not available. or the subwoofer might not have the lfe input. rather, the subwoofer may include left and right rca stereo connections, i.e. the r and l. or they can be elastic clips like the ones you’d find on the back of conventional speakers.

If the subwoofer’s “line in” uses rca cables, connect it to the subwoofer with an rca cable. If the cable splits at one end, for example, a Y cable for left and right channels, connect the R and L ports to the subwoofer. if you also have left and right rca connectors for the woofer output, you need to connect those to the receiver as well.

If your subwoofer has spring clips, you can use the receiver’s speaker output to connect them all. this is how a simple stereo speaker is connected. note the channels. If the subwoofer has two pairs of spring clips that are for the output speaker and the input speaker, the additional speakers connect to the subwoofer, which connects to the receiver for an audio signal to pass through.

If the subwoofer only has one pair of spring clips, the subwoofer must share the same receiver connections as the speaker. the easiest method to do this is to use banana clips (against overlapping bare wires) that can be connected together.

conclusion

In conclusion, subwoofers are generally easy to connect since there are only two cables available: one is used for power and the other for audio. you’re much more likely to plug in a couple of cables to spend the majority of your time positioning and tweaking a subwoofer for optimal efficiency. to always get the best output, you should always set your speakers the same. To connect the subwoofer to the receiver, you must connect your woofer to the receiver’s subwoofer output. the model of the subwoofers varies from one to another.

It is always advisable to handle these connections with the utmost care each time you make the connections. If you can’t connect your subwoofer after following the steps above, you can refer to its manual. if it still does not respond, seek help from a specialist. In circumstances where you are not so sure what to do, always contact a professional or expert. Seeking the help of an expert will save you time and prevent further damage as well.
