All About Subwoofers Subwoofers

A subwoofer is a speaker which is completely dedicated to producing only Bass effect.  Mostly Subwoofers comes in two variants, i.e., one with an inbuilt amplifier and the other with an external amplifier. The Subwoofers are mostly used in car stereos, Home theatre’s, Multimedia PC’s, etc.

They are cased inside a wooden box with a hole at the back to provide air impound which gives the bass effect. The normal frequency range for a subwoofer is 20 to 200Hz but may vary according to the models. The subwoofers are mostly sold along with a set of speakers which are mentioned in a ratio such as 2.1, 5.1 and 7.1. One of the most crucial things to be noted while fixing subwoofers is its placement, subwoofers placed in the open room produces less effect whereas when placed under a chair, sofa or at corners produce a very good effect.

The performance of the subwoofer also lies on the acoustics of the room. The installation instructions of subwoofer include connecting the subwoofer with the power adaptor provided and then connecting the speakers in their respective connectors. The secondary step is connecting the wire denoting “to sub” to the subwoofer and the other end to the device input. Today’s subwoofers come in varying designs having a remote control unit to adjust the bass effect and volume of the speakers, LCDs at the front to denote the volume and bass level, the inclusion of USB connecting port and Flashcard ports to hear music alone without having to connect with a TV or a computer.

There are some crucial things one has to decide before buying a subwoofer. Some of them are:

  • The power and performance of the subwoofer should not cause disturbance to the neighborhood.
  • Be clear with the purpose of buying subwoofer since there are several subwoofers available in the market specifically for movie experience and for music only models.
  • Decide with the size of the woofer because the size doesn’t matter with the performance of the woofer, it’s the placement that decides the performance.
  • Budget is another factor that should be taken care of because lesser the budget lesser the futures will be. Give equal consideration for budget and performance and choose the one which suits best to the need.

Guide to Wiring Subwoofers

It is essential to properly wire your subwoofer to get the maximum performance from the subwoofer when it is hooked up to your existing sound system. To achieve this your best guide is the manufacturer’s instructions and diagrams

There is no better substitute for the manufacturer’s instructions, so before you start splicing and sticking wires together, make sure that you read the product’s usage manual carefully, to ensure that your subwoofer will work when your home theatre system is turned on.

Some wiring diagrams can be difficult to understand and, not everyone is comfortable around wires. So, in this article, our discussion will focus on basic guidelines and tips that will enable you to effectively carry out the successful wiring of your subwoofer system.

The first step that you should concentrate on is how to organize the long wires that come especially with massive subwoofer systems. A cable run is an essential approach for multiple, messy wires. If you join together all the cables to form a single run, this will ensure that your space will not look cluttered because of all the wires connected to the various units.
Inspect all the ports and terminals at the back of your main speaker system. What you are looking for is to see whether there are terminals that look like switches or whether there are lots of basic ports.

Depending on what you observe by this visual inspection, you should be able to determine which terminals will be connected to your subwoofer based on the manufacturer’s instructions. The next step in the process concerns guidelines for the proper assembly of the subwoofer system.

Basic wiring of the main speakers to the subwoofer system is not generally a problem. However, before you try to make these connections, i.e., connecting the subwoofer to main speakers or sound system, always check to see whether you need to connect more wires to the back of the subwoofer. Modern subwoofers have built-in wires, but this is not always the case as in some instances additional wires need to be manually installed.

You may be wondering whether it is possible to experiment with your sound system without breaking it. Whilst you may be able to do so, this course of action is something we highly discourage. We suggest that you follow the basic schematic design first and if you choose to you can tweak it later on. Be sure to familiarize yourself with the system first before attempting any innovating for your own safety.

There needs to be a match of the impedance of your new subwoofer and that of your main speakers. The basic ratio is 500:1. What this means is that if your subwoofer has an impedance level of 500 watts, your main speaker should be set to 1 ohm.

In seeking to match up the impedance levels between your subwoofer and main speaker, if you are unsure about the most ideal setting be sure to contact the manufacturer of either your main sound system or the manufacturer of your subwoofer. One or both manufacturer should be able to help you complete the wiring of your subwoofer system.

There are existing wiring kits specially made for car installations that can be used to simplify the process of adding a subwoofer to your car. If you do a search on the internet there are plenty of websites offering these special wiring kits for sale. It is definitely worth your time to have a look at these kits, as thousands of people have already used them to hook up their new subwoofer with their existing amplifiers or speakers.

You need to be careful of wires that carry power to your subwoofer or main speakers. There is a high risk of shorting out of your system if these are not wired correctly.
