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
