The device which converts amplified electrical signals into air vibrations that a human can hear as sound is known as a speaker. There are a wide range of speakers in various sizes, shapes, models and types. But they differ on the basis of the audio spectrum. Each speaker has different capabilities for reproducing audio spectrum.Vibrations are created with such speakers which is same as the electrical signals.
Speakers are mainly of two types, distinguished on the basis of where the electric signal gets amplified.
Passive speakers are the ones which offer the basic functionalities of a speaker. For producing sound, such speakers need a separate power amplifier.
Powered speakers are those which offer an internal power amplifier. These are also known as active speakers. Due to the in-built power amplifier, such speakers connect directly to a mixer, and hence a lot of cables are reduced. But you do need an electricity power cable.
If you are looking for setting up a PA system in a simple and easy manner, then you should prefer powered speakers that need fewer connections.But then, a high level of freedom is offered by a passive speaker and thus one can easily move them around or change them. It is better to check the impedance, speaker size, sound pressure level and power rating before finalizing a speaker.
Various other speakers available are main speakers, subwoofers and monitor speaker. Listeners or audience get most of the sound with the main speakers.For boosting the sound, subwoofers are used with the main speakers which are good for low frequency sound playback.Monitor speakers are used to monitor the sound. They can be placed in various ways depending on shape or on the surface or on a stand.
We all know that grandparents and tech don’t go well together. Fortunately, there are many ways to make new technology accessible to older people. Start simple – if grandma has never used a phone or computer before, you don’t want to overwhelm her with new information. Teach her the basics first, such as writing an email or searching the web. Don’t bother teaching her skills she doesn’t need.
If she has difficulty remembering, it’s important to be patient and let her go at her own pace. Keep practicing the same things over and over again until she gets the hang of it. Make it simple – remember she is from a different generation where computers and phones did not exist for her growing up.
It’s best to follow what she is interested in – if she has no desire to learn the processes will be slow and difficult for both of you. Ask her what she would like to know about – maybe she’d like to learn how to make video calls to her grandchildren with an iPad. Or help her set up an email account so all the family can send her photos.
Learning about tech can be a great way to make older people feel less lonely. Once she has mastered the basics, ask her to teach her friends so they can have ways to keep in touch. Also, make it fun for grandma – older people love enthusiastic youngsters. Try to keep positive and encourage her as you go along.
If you are buying a gadget for your grandma, choose one which is simple. She probably doesn’t need the latest, top of the range product, and one with too many features will make the learning process more confusing. You could even try a kids’ version to begin with until she gets the hang of it.

The speaker amplifier pairing is the most crucial step. Matching the right speaker with the amplifier and vice versa can impact your sound quality a great deal. Some blindly look at the wattage mentioned. But RMS watts per channel is a more important parameter than the watt rating itself. When the amplifier’s watts per channel rating is same as the rated watts for your speaker or a little more than that value then you would get a great sound output.
Would you need subwoofer? Most people prefer installing subwoofers to improve the sound quality. Not all amplifiers however support the subwoofer connection. While most standard speakers can be connected to the amplifiers, you would have to look for those with subwoofer support. This would make sure that you have the provision when the need arises in the future.
