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 give you a step-by-step information on find out how to bridge a subwoofer. We will even talk about the advantages of bridging subwoofers and supply some ideas for troubleshooting widespread issues.
Earlier than you start, it is very important be sure that your subwoofer is suitable with bridging. Not all subwoofers will be bridged, so it is very important verify the producer’s specs. After getting confirmed that your subwoofer is suitable, you possibly can comply with 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 must be two units of terminals, one for every channel.
3. Join the constructive terminal of 1 subwoofer to the constructive terminal of the opposite subwoofer.
4. Join the adverse terminal of 1 subwoofer to the adverse terminal of the opposite subwoofer.
5. Activate the ability to your subwoofer and join the cables to your audio system.
Selecting the Proper Subwoofer
Relating to 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 remember when selecting a subwoofer for bridging:
- Energy dealing with: The ability dealing with of a subwoofer refers back to the quantity of energy it could possibly deal with with out being broken. While you bridge a subwoofer, you’re primarily doubling the ability that’s despatched to it. Due to this fact, it is very important select a subwoofer that has an influence dealing with that’s at the least twice the ability of your amplifier.
- Impedance: The impedance of a subwoofer refers back to the resistance it provides to the stream {of electrical} present. While you bridge a subwoofer, you’re primarily connecting two subwoofers in parallel. This halves the impedance of the system. Due to this fact, it is very important select a subwoofer that has an impedance that’s suitable along with your amplifier.
- Measurement and enclosure: The dimensions and enclosure of a subwoofer can even 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 can be enclosed in a sealed enclosure are inclined to have a better energy dealing with than subwoofers which can be enclosed in a ported enclosure.
After getting thought of all of those elements, you need to have the ability to select a subwoofer that’s appropriate for bridging.
| Energy Dealing with (Watts) | Impedance (Ohms) | Measurement | 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 remember to make sure that you do it accurately. Step one is to decide on the proper kind of amplifier in your subwoofer. Amplifiers are sometimes labeled by their energy output, so you will must be sure that the amplifier you select has sufficient energy to drive your subwoofer. As soon as you have chosen an amplifier, you will want to attach it to your subwoofer utilizing a speaker cable. The speaker cable must be thick sufficient to deal with the quantity of energy that the amplifier shall be delivering to the subwoofer.
As soon as you have linked the amplifier to the subwoofer, you will must activate the amplifier and regulate the quantity to a cushty degree. You might also want to regulate the crossover frequency on the amplifier to make sure that the subwoofer is barely reproducing the low frequencies that it is designed to deal with.
Bridging a Subwoofer
Bridging a subwoofer is a way that can be utilized to extend the ability output of a subwoofer. Bridging entails connecting the constructive terminal of 1 amplifier channel to the constructive terminal of the subwoofer and the adverse terminal of the opposite amplifier channel to the adverse terminal of the subwoofer. This creates a single, extra highly effective sign that’s despatched to the subwoofer. Bridging a subwoofer is usually 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
| Connection | Description |
|---|---|
| Optimistic terminal of left amplifier channel to constructive terminal of subwoofer | Connects the constructive sign from the left amplifier channel to the subwoofer. |
| Damaging terminal of proper amplifier channel to adverse terminal of subwoofer | Connects the adverse sign from the proper amplifier channel to the subwoofer. |
When bridging a subwoofer, it is very important use an amplifier that’s rated for bridged operation. Bridging an amplifier with an amplifier that isn’t rated for bridged operation can injury the amplifier.
Figuring out the Optimum Crossover Level
The crossover level is a vital think about bridging a subwoofer, because it determines the frequency vary that the subwoofer will reproduce. The perfect crossover level varies relying on the dimensions and specs of the subwoofer, in addition to the general sound system.
To find out the optimum crossover level, contemplate the next elements:
- Subwoofer Measurement: Bigger subwoofers can sometimes deal with decrease crossover factors, whereas smaller subwoofers are higher fitted to larger crossover factors.
- Subwoofer Frequency Response: The subwoofer’s frequency response signifies the vary of frequencies that it could possibly reproduce. The crossover level must be set inside the subwoofer’s frequency response vary.
- Room Measurement and Acoustics: The dimensions and form of the room, in addition to the location of the subwoofer, can affect the optimum crossover level.
The next desk offers a basic guideline for figuring out the optimum crossover level based mostly on subwoofer dimension:
| Subwoofer Measurement | Optimum Crossover Level |
|---|---|
| 8-inch | 80-120 Hz |
| 10-inch | 60-100 Hz |
| 12-inch | 40-80 Hz |
| 15-inch | 30-60 Hz |
After getting thought of these elements, you possibly can fine-tune the crossover level by listening to your system and adjusting it till you discover the sound that most accurately fits your preferences.
Choosing and Putting in a Line Stage Enter Converter (LILC)
A line degree enter converter (LILC) is a tool that lets you join a subwoofer to a automotive stereo that doesn’t have a devoted subwoofer output. LILCs convert the high-level speaker alerts from the automotive stereo into low-level RCA alerts that can be utilized to connect with the subwoofer’s amplifier.
When choosing a LILC, it is very important select one that’s suitable with the impedance of your automotive stereo and the ability output of your subwoofer amplifier. The impedance of your automotive stereo is usually 4 ohms or 8 ohms. The ability output of your subwoofer amplifier is measured in watts RMS. After getting chosen a LILC, you’ll need to put in it in response to the producer’s directions.
