Speaker is the sound receiver of your audio devices and audio speakers usually costs some amount of money. Therefore, having an appropriate maintenance for your loudspeaker is necessary and can help you prevent any extra costs in the future. The maintenance and proper operation can bring best sound quality as well as long duration for your speakers. Below are some tips for speaker maintenance.
Don’t Let Your Speakers Operate Under Extreme Heat Condition
Operate speakers or any technical devices under extremely hot condition can negatively affect the device duration. Especially, with some speakers or sound systems having devices with cooling systems installed at the bottom, some users don’t notice this design and put speakers over each other. This action can cause damage to speakers since the heat cannot escape and the cooling systems are also easier to be overload and broken. The heat then pass down to the speakers below, causing bad effect for another speakers as well. It is ok if this situation happened for a few times, however, if you let this happens for a long time, your speaker duration is certainly affected and some part will be probably damaged.
Moreover, amplifier light and amplifier class A usually produce a lot of heat which can affect other devices around the speakers. The common mistake is to put the power amplifiers under preamplifier. The operating principle of cooling systems in power amplifier is to vertically give out the heat, therefore, putting power amplifier below preamplifier or any other devices can make the devices absorb more heat themselves. The best solution is to arrange speakers and sound devices in the audio system that tend to produce more heat on the top place, in open space.
In addition, if your speakers don’t have cooling fan in inferior design, then you should equip your speakers a separate cooling fan. Besides, investing in a specialized machine shelves for your audio systems and speakers is a good recommendation to maintain and prolong your audio devices
Notice the Power Amplifier and Speakers Sensitivity
Amplifier generate power for the speaker to operate in the most effective way. But in some situation, in order to reduce the cost and utilize some available equipment, manufacturers often use amplifiers that have lower power compared to minimum power required which then leads to power insufficiency. This will consequence in lower sound quality and the treble speakers will the one that tend to be affected most.
Limit the Speaker Connection
Sometimes, in order to reduce the cost, we often connect too many speakers to an amplifier. But if your amplifier power cannot capable of such many speakers running at the same time, then this is not a good idea. It will reduce the duration of both amplifier and speakers in the sound systems.
There are 2 principles that you must notice when installing your sound systems. The impedance of the speaker systems should be consistent with the load of the amplifier. The more speakers connected to the amplifier, the lower the impedance of the systems (in the case that there are more than 2 speaker systems that you want to simultaneously pull from). More specific, you should not turn more than 2 speakers with 8 ohm impedance simultaneously while your amplifier is only able to pull a pair of 8 ohm speakers. In fact, there are not many amplifiers with 4 ohm or less impedance that can allow multiple speaker pulling at the same time. If possible, you can look for more information about principle of impedance coordination between devices to ensure the optimum system performance.
Notice Wiring, Avoid Short Circuit
Short circuits are frequent occurrences in electrical systems, leading to wires, which are more likely to damage the equipment. In general, new models of amplifier are usually designed with strong protection function for a short circuit occurrence resulted for users’ negligence in wiring. However, you should be acknowledge this problem, especially while using the sound systems. Pulling the plug in and out the speaker jack while connecting with other devices can cause short circuits and damage the amplifier in a second if you let 2 ends of the jack accidently come together.
Acknowledge the Impact of Light to Speakers
Rubber of foam ribs are very easy to decay when exposed to ultraviolet rays. If you place your speakers under sunlight for a long time, not only the speakers absorb the heat but also the ultraviolet rays can shorten your speaker life. Moreover, neon light from lamp can also cause damage to your speakers as well. Therefore, you should have some protective measures when using speakers indoor and outdoor. Shield the speakers well in order to limit the penetration of ultraviolet light.
Dirt and Dust
Dirt is the most common damage to not only speakers but also any electronic devices. Dirt and dust that clings to the circuits’ surface will reduce the transmission capacity of the speakers’ circuits. You should have cleaning schedule for your speakers to prolong the quality and duration. Your frequency will depend on the dust density in the surrounding environment.
Pay Attention to Moisture
The moisture in the atmosphere will vary for each seasons. If the moisture level in the air is too high, condensed water will stick to the face of the speakers’ circuits. Just like heat, speakers should be protected from moisture as well. Depend on the speakers’ duration and material, you should take some extra measures to strengthen the ability to conserve the moisture. Water is a very good conductor of electricity, therefore, water accumulation on circuit surface will cause short circuits and damage to the audio devices. The best solution for this problem is to use the moisture pack in the cabinet made of pressed wood. With other materials, depend on the needs that users can put in some material such as sand, foam or cotton swab for better preservation. To make sure your speakers and audio systems stay dry, use a dryer to dry the surface of the boards and components in electronic equipment. Be careful not to dry with high heat, since high heat is not good for speakers either.
Above are some preservation tips for your speakers. Hopefully it will help you in the process of using the audio equipment, especially the speakers in your sound system.
