The world of audiophiles is filled with debates and myths surrounding the concept of speaker break-in, also known as speaker burn-in. The idea that speakers require a certain period of use before they reach their optimal performance has been a topic of discussion among audio enthusiasts for decades. In this article, we will delve into the world of speaker break-in, exploring its history, the science behind it, and the opinions of experts in the field.
A Brief History of Speaker Break-In
The concept of speaker break-in dates back to the early days of loudspeaker design. In the 1950s and 1960s, speakers were made with materials that were prone to stiffness and required a certain amount of use before they became supple and responsive. The idea was that the more you used your speakers, the better they would sound. This notion was perpetuated by manufacturers, who often recommended a break-in period for their products.
The Science Behind Speaker Break-In
So, what exactly happens during the break-in process? There are several theories, but the most widely accepted explanation is that the materials used in speaker construction, such as the surround, spider, and voice coil, undergo a process called “mechanical relaxation.” This means that the materials become less stiff and more compliant over time, allowing the speaker to produce sound more efficiently.
Another theory suggests that the break-in process involves the “forming” of the voice coil and magnet assembly. As the speaker is used, the voice coil and magnet become more aligned, resulting in improved sound quality.
The Role of Materials in Speaker Break-In
The type of materials used in speaker construction plays a significant role in the break-in process. For example, speakers made with polypropylene or polyethylene surrounds tend to require a longer break-in period than those made with rubber or foam surrounds. This is because polypropylene and polyethylene are stiffer materials that take longer to relax.
On the other hand, speakers made with high-quality, specially designed materials may not require a break-in period at all. These materials are designed to be more compliant and responsive from the start, eliminating the need for a break-in period.
Expert Opinions on Speaker Break-In
We spoke with several experts in the field of audio engineering and design to get their take on speaker break-in.
Interview with John Atkinson, Editor-in-Chief of Stereophile Magazine
“I think the idea of speaker break-in is a bit of a myth,” says John Atkinson, Editor-in-Chief of Stereophile Magazine. “While it’s true that some speakers may sound better after a certain period of use, this is not necessarily due to the break-in process. Rather, it’s often the result of the listener becoming more familiar with the speaker’s sound.”
Atkinson also notes that the break-in process can be influenced by a variety of factors, including the type of music being played, the volume level, and the room acoustics.
Interview with Paul Barton, Founder of PSB Speakers
Paul Barton, founder of PSB Speakers, takes a different view. “I believe that speaker break-in is a real phenomenon,” he says. “Our research has shown that the materials used in speaker construction do undergo a process of mechanical relaxation over time, resulting in improved sound quality.”
Barton also notes that the break-in process can be accelerated by playing music with a wide range of frequencies and dynamics. “This helps to loosen up the materials and get them working together more efficiently,” he explains.
How to Break In Your Speakers
If you’re convinced that your speakers need to be broken in, here are some tips to help you get started:
- Play music with a wide range of frequencies and dynamics. This will help to loosen up the materials and get them working together more efficiently.
- Start with low volumes and gradually increase the level over time. This will help to prevent damage to the speaker and allow the materials to relax gradually.
- Avoid playing music with a lot of bass content, as this can put excessive stress on the speaker.
- Use a break-in CD or DVD, which is specifically designed to help break in your speakers. These discs typically feature a wide range of frequencies and dynamics, and are designed to be played at low volumes.
Break-In Period: How Long Does it Take?
The length of time required to break in your speakers varies depending on the type of speaker and the materials used in its construction. Here are some general guidelines:
- 10-20 hours: This is a typical break-in period for most speakers. During this time, the materials will start to relax, and the sound quality will improve.
- 20-50 hours: This is a more extended break-in period, which may be required for speakers made with stiffer materials.
- 50-100 hours: This is a prolonged break-in period, which may be required for high-end speakers made with exotic materials.
Conclusion
The debate surrounding speaker break-in continues to rage on, with some experts arguing that it’s a real phenomenon, while others claim it’s a myth. While the science behind speaker break-in is complex, it’s clear that the materials used in speaker construction play a significant role in the process.
Whether or not you believe in speaker break-in, one thing is certain: playing music through your speakers will help to loosen up the materials and improve the sound quality over time. So, go ahead and play your favorite tunes, and enjoy the music!
Final Thoughts
In conclusion, the concept of speaker break-in is a complex and multifaceted topic. While some experts argue that it’s a real phenomenon, others claim it’s a myth. Ultimately, the decision to break in your speakers is up to you. If you’re unsure, try playing music through your speakers for an extended period and see if you notice an improvement in sound quality.

What is speaker break-in, and why is it necessary?
Speaker break-in, also known as speaker burn-in, is the process of allowing a new pair of speakers to play music for an extended period to loosen up the suspension and diaphragm of the drivers. This process is believed to improve the sound quality of the speakers by allowing the materials to settle and become more flexible. The idea behind speaker break-in is that the drivers in a new pair of speakers are stiff and need time to loosen up and reach their optimal performance.
During the break-in process, the drivers are subjected to various frequencies and sound pressures, which help to loosen up the suspension and diaphragm. This, in turn, allows the speakers to produce a more accurate and detailed sound. The break-in process can take anywhere from a few hours to several weeks, depending on the type of speakers and the amount of use they receive.
How long does it take to break in a pair of speakers?
The break-in time for a pair of speakers can vary greatly, depending on the type of speakers and the amount of use they receive. Some speakers may take only a few hours to break in, while others may take several weeks or even months. Generally, it is recommended to break in a pair of speakers for at least 40-50 hours before they reach their optimal performance.
It’s also worth noting that the break-in process is not a one-time event, but rather an ongoing process. Speakers will continue to break in over time, even after the initial break-in period. However, the most significant improvements in sound quality will typically occur during the first few weeks of use.
What are the benefits of breaking in a pair of speakers?
Breaking in a pair of speakers can have several benefits, including improved sound quality, increased bass response, and a more detailed and accurate soundstage. During the break-in process, the drivers in the speakers become more flexible and able to produce a wider range of frequencies, resulting in a more immersive and engaging listening experience.
In addition to improved sound quality, breaking in a pair of speakers can also help to reduce the risk of driver failure. When speakers are new, the drivers can be stiff and more prone to damage from sudden or extreme sound pressures. By breaking in the speakers, the drivers become more flexible and better able to withstand these pressures, reducing the risk of damage or failure.
Can I break in my speakers with music or do I need a special break-in track?
While it is possible to break in a pair of speakers with music, using a special break-in track can be more effective. A break-in track typically consists of a variety of frequencies and sound pressures designed to loosen up the drivers and suspension of the speakers. These tracks can be found online or on break-in CDs and are specifically designed to help break in speakers.
That being said, breaking in a pair of speakers with music can also be effective, especially if you listen to a wide range of music with varying frequencies and sound pressures. However, using a break-in track can be more efficient and effective, as it is specifically designed to target the drivers and suspension of the speakers.
Do all speakers need to be broken in?
Not all speakers need to be broken in, but most do. Some speakers, such as those with ribbon or electrostatic drivers, do not require break-in, as these types of drivers do not have a suspension or diaphragm that needs to be loosened up. However, most speakers with dynamic drivers will benefit from break-in.
It’s also worth noting that some speakers may be designed to be “break-in free,” meaning that they are designed to sound their best right out of the box. However, even in these cases, some break-in may still be beneficial, as the drivers will still become more flexible and accurate over time.
How can I tell if my speakers are broken in?
There are several ways to tell if your speakers are broken in, including improved sound quality, increased bass response, and a more detailed and accurate soundstage. You may also notice that the speakers sound more relaxed and natural, with less harshness or brightness.
Another way to tell if your speakers are broken in is to listen for a more even and balanced sound. When speakers are new, they can sound uneven or unbalanced, with some frequencies being overemphasized or underemphasized. As the speakers break in, the sound should become more even and balanced, with all frequencies being reproduced accurately.
Can I damage my speakers by breaking them in too much?
Yes, it is possible to damage your speakers by breaking them in too much. Over-breaking in a pair of speakers can cause the drivers to become too loose, leading to a loss of sound quality and potentially even damage to the drivers.
It’s also worth noting that breaking in a pair of speakers too aggressively can cause damage to the drivers or other components. For example, playing music at extremely high volumes or using a break-in track that is too intense can cause damage to the drivers or other components. It’s always best to follow the manufacturer’s recommendations for break-in and to use common sense when breaking in a pair of speakers.
