Understanding Subwoofers: What They Do
Before diving into how to connect two subwoofers, let’s briefly discuss what subwoofers are. A subwoofer is a specialized speaker designed to reproduce low-frequency sound, typically below 200 Hz. This low-end audio is essential for genres like hip-hop, EDM, rock, and classical music, making subwoofers indispensable for a complete audio setup.
The Benefits of Using Two Subwoofers
When considering whether to incorporate a second subwoofer into your audio system, it’s essential to understand the benefits. Here are some key advantages:
- Improved Sound Quality: Dual subwoofers can deliver a better soundstage and enhance audio clarity, providing an overall richer listening experience.
- Balanced Bass Response: Two subwoofers can help smooth out the low-frequency response in your room, reducing peaks and dips caused by acoustic properties.
Types of Subwoofer Configurations
When you’re ready to set up your dual subwoofer system, there are two primary configurations to consider: parallel and series connections. Let’s explore each of these setups in detail.
Parallel Connection
In a parallel setup, both subwoofers receive the same audio signal from the amplifier. This is typically the most common way to connect two subwoofers, especially in home theater systems.
Wiring Parallel Connections
To connect your subwoofers in parallel, follow these steps:
- Identify your amplifier’s output—ensure it has support for multiple channels.
- Depending on your subwoofers’ impedance ratings, connect the positive terminal of the amplifier to the positive terminals of both subwoofers.
- Repeat the process for the negative terminals.
This configuration allows both subwoofers to work together, amplifying the bass output effectively.
Series Connection
In a series configuration, one subwoofer connects to the other in a daisy-chain fashion, creating a single pathway for the audio signal. This setup is often used for specific applications where only one channel is available.
Wiring Series Connections
To hook up your subwoofers in a series connection, do the following:
- Choose one subwoofer to be the primary unit plugged directly into the amplifier.
- Connect the positive terminal of the first subwoofer to the amplifier’s positive terminal.
- Connect the negative terminal of the first subwoofer to the positive terminal of the second subwoofer.
- Finally, connect the negative terminal of the second subwoofer to the amplifier’s negative terminal.
This method may limit the total output, so it’s less commonly used for larger setups.
Factors to Consider When Hooking Up Two Subwoofers
Before proceeding with your installation, there are several critical factors to consider to ensure your setup functions optimally:
1. Amplifier Compatibility
Make sure your amplifier can handle the combined impedance of both subwoofers. For example, if you have two 4-ohm subwoofers connected in parallel, the total load on your amplifier will be 2 ohms. Check the specifications to avoid overloading your amplifier.
2. Placement in the Room
Subwoofer placement plays a significant role in sound quality. Ideally, position your subwoofers near walls and corners to maximize bass output. Avoid placing them in completely opposite areas of the room to maintain a cohesive audio experience.
3. Calibration
Once your subwoofers are hooked up, you’ll need to calibrate them for optimal performance. Use an SPL meter or a calibration mic to ensure that both subwoofers are outputting sound evenly. Adjust the gain and crossover settings on your AV receiver or amplifier to create a balanced sound profile.

What are the benefits of using two subwoofers instead of one?
Using two subwoofers can significantly enhance your audio experience in several ways. Firstly, dual subwoofers provide improved bass distribution throughout the room, minimizing dead spots where the bass might be weak or uneven. This leads to a more immersive listening experience, whether you’re enjoying music, movies, or gaming. Additionally, having two subs can help to achieve better overall sound pressure levels, allowing you to enjoy deeper and more powerful bass without distortion.
Secondly, two subwoofers can also reduce the demand on each individual unit, allowing them to operate more efficiently at lower volumes. This can lead to a cleaner sound with less distortion, enhancing the clarity of the bass frequencies. Moreover, two subwoofers can help in accommodating larger spaces more effectively, making them a popular choice for home theaters or expansive listening areas where one subwoofer might struggle to fill the space adequately.
How do I connect two subwoofers to my audio system?
Connecting two subwoofers can vary depending on the type of audio equipment you have. Generally, you’ll want to identify the outputs on your audio receiver. Most modern receivers have multiple subwoofer outputs, which will often allow you to simply run two separate cables to each subwoofer. If your receiver doesn’t have multiple outputs, you can use a y-splitter cable from the single subwoofer output to connect both subs simultaneously, ensuring that both will receive the same audio signal.
Once you have the physical connections established, you should also consider the placement of the subwoofers for optimal sound performance. Common practices include placing them in opposite corners of the room or near the front wall to enhance bass response. After physical setup, testing phase is essential—experiment with phase settings and crossover frequencies to achieve the best blend with your main speakers.
Do I need a special amplifier for two subwoofers?
In most cases, you won’t necessarily need a special amplifier as many modern subwoofers come with built-in amps designed to drive them independently. If both subwoofers have their internal amplification, simply using the appropriate connections from your receiver is sufficient. However, if you’re using passive subwoofers, or if you’re looking for enhanced performance, you may consider investing in a dedicated subwoofer amplifier that can handle the power requirements for both units.
When using a shared amplifier for passive subwoofers, ensure that it has enough power to drive both without risking overloading. Check the manufacturer’s specifications for each subwoofer to determine the total wattage required and ensure the amplifier can handle this load. An underpowered amplifier may result in distortion, while an overpowered one could cause irreversible damage to your subwoofers.
How should I place my two subwoofers for best performance?
The placement of subwoofers is crucial for optimal sound performance. In most cases, placing subwoofers near your main listening area will provide a more balanced and immersive sound. An effective method to determine the best location is to use the “subwoofer crawl” technique. Start by setting up the subwoofers at your main seating position, then play a bass-heavy track and crawl around the perimeter of the room to identify spots where the bass response is strongest. Once identified, you can place your subwoofers in those locations for optimal performance.
Additionally, keep in mind that the size and shape of your room will affect how bass travels. Sometimes, placing subwoofers in opposite corners can help reduce wave interference, though this isn’t a one-size-fits-all solution. Experimentation is key, and adjusting your subwoofer’s phase settings and crossover frequency can further refine the overall bass sound, ensuring it integrates well with your other speakers.
What is the difference between using stereo vs. mono subwoofer connections?
The primary difference between stereo and mono subwoofer connections lies in how the audio signal is received and distributed to the subwoofers. In a stereo connection, each subwoofer receives a different channel of audio, which can create a more distinct stereo imaging and a wider soundstage. This setup can enhance the overall listening experience, especially in music applications, allowing for more detailed sound separation and a realistic audio environment.
On the other hand, with a mono connection, both subwoofers receive the same audio signal, which is typically preferred in home theater setups. This configuration provides a consistency of bass response across the front stage, helping to create a more cohesive sound blend with your main speakers. Ultimately, the choice between stereo and mono will depend on your personal preference, the type of content you’re consuming, and the specifics of your room arrangement.
Can two subwoofers create phase issues in my audio setup?
Yes, connecting two subwoofers can potentially introduce phase issues, which occur when sound waves from both subwoofers interact in a way that can either amplify (constructive interference) or cancel (destructive interference) the bass frequencies. Properly managing phase settings is essential to avoid these issues and achieve a balanced sound. Most subwoofers come with a phase switch or control that allows you to adjust the phase alignment based on their placement in the room relative to your main speakers and listening position.
To troubleshoot phase issues, you can perform listening tests at different phase settings and choose the one that delivers the most accurate and strong bass response. Additionally, adjustments to the placement of the subwoofers may also help in reducing phase-related problems. Balancing both phase settings and room acoustics will ensure a cohesive and powerful bass performance that enhances your overall audio experience.
