Bridging a subwoofer is a good way to enhance the sound high quality of your private home audio system. By connecting two subwoofers collectively, you possibly can create a extra highly effective and immersive bass expertise. On this article, we’ll offer you a step-by-step information on learn how to bridge a subwoofer. We may even focus on the advantages of bridging subwoofers and supply some suggestions for troubleshooting widespread issues.
Earlier than you start, you will need to be sure that your subwoofer is appropriate with bridging. Not all subwoofers may be bridged, so you will need to examine the producer’s specs. After getting confirmed that your subwoofer is appropriate, you possibly can observe these steps to bridge it:
1. Flip off the ability to your subwoofer and disconnect all cables.
2. Find the speaker terminals on the again of the subwoofer. There needs to be two units of terminals, one for every channel.
3. Join the optimistic terminal of 1 subwoofer to the optimistic terminal of the opposite subwoofer.
4. Join the destructive terminal of 1 subwoofer to the destructive terminal of the opposite subwoofer.
5. Activate the ability to your subwoofer and join the cables to your audio system.
Selecting the Proper Subwoofer
On the subject of bridging a subwoofer, the primary and most necessary step is selecting the best subwoofer. Not all subwoofers are created equal, and never all of them are appropriate for bridging. Right here are some things to bear in mind when selecting a subwoofer for bridging:
- Energy dealing with: The facility dealing with of a subwoofer refers back to the quantity of energy it may deal with with out being broken. While you bridge a subwoofer, you might be basically doubling the ability that’s despatched to it. Subsequently, you will need to select a subwoofer that has an influence dealing with that’s a minimum of twice the ability of your amplifier.
- Impedance: The impedance of a subwoofer refers back to the resistance it presents to the circulation {of electrical} present. While you bridge a subwoofer, you might be basically connecting two subwoofers in parallel. This halves the impedance of the system. Subsequently, you will need to select a subwoofer that has an impedance that’s appropriate along with your amplifier.
- Dimension and enclosure: The scale and enclosure of a subwoofer may also have an effect on its suitability for bridging. Bigger subwoofers are inclined to have extra energy dealing with and decrease impedance than smaller subwoofers. Moreover, subwoofers which are enclosed in a sealed enclosure are inclined to have the next energy dealing with than subwoofers which are enclosed in a ported enclosure.
After getting thought-about all of those components, you must be capable of select a subwoofer that’s appropriate for bridging.
| Energy Dealing with (Watts) | Impedance (Ohms) | Dimension | Enclosure |
|---|---|---|---|
| 500-1000 | 4 or 8 | 12″ or 15″ | Sealed |
| 1000-2000 | 2 or 4 | 15″ or 18″ | Ported |
Connecting the Subwoofer to an Amplifier
Connecting a subwoofer to an amplifier is a comparatively easy course of, however there are some things you want to bear in mind to make sure that you do it accurately. Step one is to decide on the fitting kind of amplifier in your subwoofer. Amplifiers are sometimes labeled by their energy output, so you may have to be sure that the amplifier you select has sufficient energy to drive your subwoofer. As soon as you’ve got chosen an amplifier, you may want to attach it to your subwoofer utilizing a speaker cable. The speaker cable needs to be thick sufficient to deal with the quantity of energy that the amplifier might be delivering to the subwoofer.
As soon as you’ve got related the amplifier to the subwoofer, you may have to activate the amplifier and modify the amount to a snug degree. You might also want to regulate the crossover frequency on the amplifier to make sure that the subwoofer is simply reproducing the low frequencies that it is designed to deal with.
Bridging a Subwoofer
Bridging a subwoofer is a method that can be utilized to extend the ability output of a subwoofer. Bridging includes connecting the optimistic terminal of 1 amplifier channel to the optimistic terminal of the subwoofer and the destructive terminal of the opposite amplifier channel to the destructive terminal of the subwoofer. This creates a single, extra highly effective sign that’s despatched to the subwoofer. Bridging a subwoofer could be a great way to enhance the efficiency of a subwoofer in a big room or in a system with a number of subwoofers.
Desk: Bridging a Subwoofer
