Bridging a subwoofer is a good way to enhance the sound high quality of your own 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 easy methods 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 make it possible for your subwoofer is suitable with bridging. Not all subwoofers will be bridged, so it is very important examine the producer’s specs. After you have confirmed that your subwoofer is suitable, you possibly can observe these steps to bridge it:
1. Flip off the facility 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 optimistic terminal of 1 subwoofer to the optimistic terminal of the opposite subwoofer.
4. Join the detrimental terminal of 1 subwoofer to the detrimental terminal of the opposite subwoofer.
5. Activate the facility to your subwoofer and join the cables to your audio system.
Selecting the Proper Subwoofer
With regards 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 bear in mind 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 deal with with out being broken. Whenever you bridge a subwoofer, you might be basically doubling the facility 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 very least twice the facility of your amplifier.
- Impedance: The impedance of a subwoofer refers back to the resistance it presents to the circulate {of electrical} present. Whenever you bridge a subwoofer, you might be basically 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 together with your amplifier.
- Measurement and enclosure: The dimensions and enclosure of a subwoofer may have an effect on its suitability for bridging. Bigger subwoofers are likely to have extra energy dealing with and decrease impedance than smaller subwoofers. Moreover, subwoofers which can be enclosed in a sealed enclosure are likely to have the next energy dealing with than subwoofers which can be enclosed in a ported enclosure.
After you have thought of all of those elements, you must be capable 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 bear in mind to make sure that you do it appropriately. Step one is to decide on the fitting sort of amplifier to your subwoofer. Amplifiers are sometimes categorized by their energy output, so you may must make it possible for 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 must be thick sufficient to deal with the quantity of energy that the amplifier will probably be delivering to the subwoofer.
As soon as you’ve got related the amplifier to the subwoofer, you may 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 facility output of a subwoofer. Bridging includes connecting the optimistic terminal of 1 amplifier channel to the optimistic terminal of the subwoofer and the detrimental terminal of the opposite amplifier channel to the detrimental 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 |
|---|---|
| Constructive terminal of left amplifier channel to optimistic terminal of subwoofer | Connects the optimistic sign from the left amplifier channel to the subwoofer. |
| Damaging terminal of proper amplifier channel to detrimental terminal of subwoofer | Connects the detrimental sign from the fitting 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 harm the amplifier.
Figuring out the Optimum Crossover Level
The crossover level is a crucial consider bridging a subwoofer, because it determines the frequency vary that the subwoofer will reproduce. The best crossover level varies relying on the scale 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 reproduce. The crossover level must be set throughout the subwoofer’s frequency response vary.
- Room Measurement and Acoustics: The dimensions and form of the room, in addition to the position of the subwoofer, can affect the optimum crossover level.
The next desk gives a normal guideline for figuring out the optimum crossover level based mostly on subwoofer measurement:
| 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 you have 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.
Deciding on and Putting in a Line Degree Enter Converter (LILC)
A line degree enter converter (LILC) is a tool that permits you to join a subwoofer to a automobile stereo that doesn’t have a devoted subwoofer output. LILCs convert the high-level speaker alerts from the automobile stereo into low-level RCA alerts that can be utilized to hook up with the subwoofer’s amplifier.
When choosing a LILC, it is very important select one that’s suitable with the impedance of your automobile stereo and the facility output of your subwoofer amplifier. The impedance of your automobile stereo is usually 4 ohms or 8 ohms. The ability output of your subwoofer amplifier is measured in watts RMS. After you have chosen a LILC, you will have to put in it in keeping with the producer’s directions.
