Speaker Sensitivity Explained

Speaker Sensitivity Explained

Blog
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

What Are Stereo Amplifiers and How Do They Work?

Blog
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
IPX4 Water Resistance Rating Explained

IPX4 Water Resistance Rating Explained

Blog
If you’ve been buying modern electronic devices, especially earbuds and speakers, you have probably heard about the IPX4 rating. We assume that you have some basic understanding of IPX ratings but we’ve decided to write a short article about IPX4 water resistance rating and explain its meaning and importance. Many of today’s products are classified as water-resistant, water repellent, waterproof or hydrophobic. These terms are used to describe the level of protection against liquid intrusion and are often misunderstood because they are used in different situations and for different types of products. For example, the terms “water-resistant”, “water repellent” and “hydrophobic” are usually used to describe the level of clothes protection while the term “waterproof” is used to describe th

5.1 Surround Sound vs. 7.1 Surround Sound

5.1 Surround Sound vs. 7.1 Surround Sound

Blog, Comparisons
Surround sound systems have become popular only recently and this is what makes people think of them as of some new technology. Well, this is far from the truth as surround sound systems came into existence with the introduction of surround sound audio formats back in the 1930s. As you could probably guess, surround sound systems first appeared in the film industry and Disney was responsible for this innovation. At the time, the technology was too expensive for application because it required numerous speakers to create the effect of surround sound in a movie theater, so the creators gave up on it. This question was raised again in the 1950s (again, in the film industry) but its real expansion didn't start until 1975 when a new sound format Dolby Stereo appeared (you can find a more thorou...

How to Measure Sound Quality of Headphones

Blog, How to
Ever since the first pair of headphones has been made, the discussions regarding their quality among their users have been arising. The huge growth of the audio industry and consumer market brought endless lists of different headphone models into our lives and caused discussions to grow into disputes between regular users, professionals, and audiophiles.

No matter if you are just an ordinary user, a professional musician or simply an audiophile, you will definitely understand what we are talking about. The whole point of the previously men...
What Are Powered Speakers?

What Are Powered Speakers?

Blog
If you’re planning to enrich your home with a new audio system, you must’ve come across the term powered speakers. As this term always comes along with the term unpowered (or passive) speakers and as the understanding of powered speaker working principles significantly depends on the understanding of the working principles of the unpowered/passive speakers, we will try to explain both types, and then focus our attention to the powered ones. Basically, it all starts with the necessity to connect the speakers to the audio source (player, streamer, computer, etc.) and make them work. Speakers produce the sound which is the consequence of driver movements (sound vibrations), you must power the speaker in order to make the driver move and deliver the sound you want to listen to. The speakers

What are the Parts of a Stereo System?

What was your first thought when you read this headline? Some of you may have some knowledge of audio systems but many people don’t know anything about them and others think that the question is absurd because the only logical answer is that a stereo system consists of a pair of speakers. However, those who have some kind of a stereo system know that they are much more complicated than it seems. Of course, the speakers are the integral parts of any audio system but they are commonly considered the only part of the system. After all, they are the most obvious parts that everyone sees and the parts where the music is coming from. Well, this is not entirely true because stereo systems consist of at least three parts that have a great impact on the quality of the sound. If you are inter
