Speakers are widely popular audio devices and they are produced in many versions, shapes, and colors. They can be big or small, wired or wireless, you can buy a single speaker or a speaker system. They can be found anywhere and everyone wants them. We may think we know everything about them but there is actually one less known type that we don’t write about so often. These are PA speakers and in this article, we will try to present them to you in the best possible way, list their positive and negative characteristics and give you a short buying guide that should help you decide which PA speaker set is best for you. What Are PA Speakers and Why Do We Need Them? Before we even start, let’s find out what PA stands for. It actually means “public address” and these systems are made in orde

Whenever we are buying new devices, we are trying to get the best possible model for our money. However, our choice is not always only ours. We often decide what to buy based on the current trends, our current budget, where we are going to use certain device, etc. The same rule applies to buying speakers for our working or living space. We are sure most of us would like to experience watching a movie with an expensive home theater system. If we had that in our homes, we wouldn’t even have to go to the cinema. Unfortunately, not everyone has enough money to spend on these systems or enough space to place that kind of a system. This is where the compromising begins. In this article, we will try to list and explain all the differences between soundbars and surround sound speaker systems an

Reading all those numbers from the speaker’s specifications list can be a real nightmare if you don’t know what to look for and what all the numbers mean. Even if you have some basic understanding of these specifications, you might get confused by different measurement methods and different units. One of the characteristics that can be really tricky is speaker sensitivity and there are numerous reasons for that – some manufacturers call it efficiency (sensitivity and efficiency are not the same things), some manufacturers use dB at 1m per 1W, others use dB at 1m per 2.83V, different manufacturers use different measurement methods, etc. The main problem with sensitivity is that there is no industry standard when it comes to measuring and unit of measurement that would be the same for all th

Almost every child today has a phone, tablet or uses his/her parent’s computer occasionally. You may consider it positive or not but the facts are facts and we all have to accept them and deal with them. As children start using these devices at an early age (even at the age of 3 or 4), many parents are trying to ensure at least some basic protection for their children’s ears. Luckily, many companies have started producing special volume-limiting headphones that are supposed to be safe for children. We say “supposed to be safe” because we are not confident about them and in this article, we will discuss it and explain our opinion. What Are Volume-Limiting Headphones? Volume-limiting headphones are headphones specially made to enable listening to music in a “safe” mode. Their loudness is l

Before we start talking about stereo amplifiers, let’s say a few words about amplifiers in general because we are sure many people don’t completely understand the working principle of an amplifier. What Are Amplifiers? The first amplifier was invented by an American engineer Lee de Forest in the early 1900’s. The invention was, in fact, the electron vacuum tube that was named ‘’Audion’’ and its purpose was to amplify weak current. That, however, wasn’t the final design of the amplifier as the followers of Mr. de Forest (Irving Langmuir and Edward Armstrong) managed to really understand how the amplifier worked and perfect it based on the new knowledge. They made the triode – vacuum tube with no air that contains three components (positive terminal – platinum plate, negative terminal – ca

We will all agree that modern technologies make our lives much easier. It is easier to communicate, we can work from home, etc. The devices are being improved every day and we aren’t stuck with one piece of equipment for a long time. The good thing is we get to choose and we have more options than before. However, every improvement changes the way we use our devices. They used to be very simple, each of them had only one purpose, and we could connect it to only one device. Today, we can use them in many different ways. Modern devices, especially TVs, speaker systems or soundbars, can be connected to many different devices and they have numerous input and output ports. Connecting your soundbar to your TV is not very difficult and there are two main ways to connect them but the way you

Headphones are the unavoidable accessories for the majority of the population, especially young people and businessmen. This is the fact and we can do nothing about that. Modern global living conditions (which mostly refer to the living conditions in big cities) dictate behavior rules and create our lifestyle. To be honest, it is quite difficult to survive crowds, noise, commuting, etc. Music makes everything easier and everyday activities like walking through the noisy city, riding on crowded buses or using metro are not the exception. If we benefit from a piece of technology, we shouldn’t stop using it because it can harm us at some point. Everything has its advantages and disadvantages. The point is to become aware of the potential damage and try to avoid it as much as possible.
