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
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
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
The year-end is near and it's the perfect time to look back and try to make some reflections. 2019 was an incredibly productive and exciting year for all of us at AudioReputation. We've tested so many amazing products - headphones, earbuds, speakers, home theater systems, DACs, amps, preamps, etc. Some of them were incredibly innovative, even revolutionary. Some have pushed the boundaries of exceptional sound quality and listening experience. We wanted to honor those best of the best and tell the world about their excellence. That’s what this article is about. We’ve had a difficult time trying to make a comprehensive selection and not to forget something. There were so many great products but we finally did it. We’ve selected the best products of the year 2019 and arranged them int
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...
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. Their disagreements do not refer only to the headphone overall quality (physical appearance, build quality, comfort level) or to the superiority of a specific model over other models but also to the possibility to objectively measure sound quality. 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...
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
Have you ever had one of those moments when watching a movie in a cinema and wondering how they managed to achieve such a nice and powerful sound? Well, in most of the action or dramatic scenes, the key is the subwoofer. This thing is one of the key elements of every good speaker system, no matter if it is 2.1, 5.1, 7.1, or bigger. If you want to buy a great home theater system or to add a subwoofer to your existing speaker system, stay with us and you will find out all about the importance of a subwoofer and about different ways of optimizing the subwoofer’s performance. What Is Subwoofer and How It Works? Subwoofers are different from the regular speakers because they are made specially for reproducing very low-frequency tones, usually from 20 to 125 Hz (or up to 200Hz). Subwoofers ar
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
