What are foam surrounds?
Good speakers are often passed down through generations in your family. Many older, antique speakers are not only beautiful to look at, but they are also well-made with high-quality wood cabinets.
The vast majority of speakers provide years of trouble-free enjoyment. However, drivers, like many other goods, contain wear and tear parts such as capacitors and surrounds. Surrounds are the soft rings on the woofers that are attached to the inside and outside of the speaker cone and basket. When the speaker is turned on, they flex. Surrounds, which are usually constructed of foam or rubber, degrade and dissolve with time. Surrounds are easy and inexpensive to replace with our speaker repair kits. Your speakers will sound brand new after you replace the surrounds. Here at SoundImports, you can find foam surround kits for a wide variety of brands, models, and sizes of speakers.
How long do speaker foam surrounds last?
Foam and rubber surrounds are the two most prevalent types of surrounds found on speakers, as previously stated. Rubber surrounds survive longer than foam surrounds, although they will ultimately wear out as well. Over time, foam surrounds tend to disintegrate and crumble. The average lifespan of foam surrounds is ten to fifteen years. There are, however, always exceptions! Some speaker surrounds might last up to two times longer!
What are the differences between a foam surround and a rubber surround?
Foam is more elastic than rubber, providing the woofer with a modest advantage in terms of efficiency. Furthermore, foam is less expensive than rubber, cutting production costs and, as a result, retail prices.
Rubber surrounds are slightly more expensive than foam surrounds, but they have the advantage of lasting far longer. Rubber surrounds can easily endure between 20 and 30 years, but foam surrounds have a service lifetime of 10 to 15 years, sometimes longer.
Rubber surrounds, on the other hand, do not last indefinitely and have drawbacks when compared to foam surrounds! Rubber surrounds, for example, tend to sag. The upper half of the rubber surround will sag due to the weight of the speaker cone. This causes the voice coil to rub against the magnet, which is undesirable and sometimes can even cause a way shorter lifespan! To solve this problem in the short term, remove the woofer from the speaker cabinet, turn it 180 degrees (upside down), and reinstall it. Another issue with rubber surrounds, particularly those with a lot of softeners, is that once the majority of the softeners have evaporated, the surrounds may stiffen and crack.
That does not mean that rubber surrounds are entirely awful. They have a longer lifespan than foam surrounds, but they also offer additional benefits. For example, when using the speakers near a sea or ocean. The salty sea air will quickly dry out and fracture the foam surrounds. Using speakers outside, such as portable Bluetooth speakers or speakers at events — one day in the rain, the next in the heat, and lastly when it freezes. The weather may quickly harm foam surrounds, causing them to mould or fracture.
