  "Measurements are better than opinions," proposed F. E. Toole and other influential voices in the audio world. Their clear opinion was that a new standard for measuring speakers and presenting data should be agreed upon: the Standard Method of Measurement for In-Home Loudspeakers, ANSI/CTA-2034-A. In short, they had enough of opinions suggesting that a speaker sounds "blue" and its bass is particularly "boxy".

  Sound Wave Length and Propagation. The length of a sound wave is determined by its frequency and the speed of sound propagation. While the speed of sound propagation varies with different air temperatures, for calculations, room temperature and a sound speed of 343 m/s can be used.

  Sound Pressure and System Power. Sound loudness, specifically sound pressure, is measured in decibels (dB). The decibel scale is relative and always referenced to a certain value (human hearing threshold, device maximum capability, etc.). The decibel scale can have both positive and negative values.

  In today's era of streaming, using Bluetooth for audio playback is a necessity rather than an option. However, not all Bluetooth connections are created equal. By default, phones use energy-efficient and stable connections but often with low-quality codecs. Currently, the only high-quality codec available on Android phones is LDAC (Lossless Digital Audio Codec).

  Music frequency distribution is a crucial factor in speaker development. It's pointless to design speakers for frequencies that don't exist in music, but equally important to ensure that all essential frequencies are covered. While the concept seems straightforward, comprehensive statistics on music frequency distribution are surprisingly scarce.

  Blog posts here have mentioned that some speaker problems can be solved with an equalizer. Let’s take a closer look at what kind of equalizer is needed and how to use it. Firstly, a "parametric equalizer" is needed. This means a simple thing: for each adjustment, you can choose the frequency, the amount of change, and the width of the frequency band to be adjusted.

  Speaker directivity for enveloping. Speaker directivity should be decided before purchasing a speaker. Directivity depends solely on the speaker's construction and cannot be changed later. While placement and speaker direction can slightly adjust the direct sound and the proportion and direction of reflected sounds, the speaker's construction determines the core. Directivity is crucial for achieving both sound clarity and a enveloping.

  At home, you have another much larger speaker enclosure for your music. It's the listening room. The resonant frequency of a closed room is a quarter of the wavelength and its multiples. Depending on the positions of the speaker and the listener, additional sound reflections and their interference occur. Imagine a jagged line oscillating up and down – this is the graph of how your room's sound changes.

  Sound Frequencies and Music Quality. A sound wave in the air can be visualized as a pressure wave consisting of densely packed and sparse regions. Lower sounds are modulated with finer lines that carry higher frequencies. The precise shape of these lines carries information about the frequency and amplitude of the sound.

  The greatest advantage of stereo sound is that the entire music selection is recorded, mixed, and designed for stereo. Thus, when listening to stereo, or two-channel audio, one can be sure - the sound is exactly what the artist intended to deliver. However, two channels also have their clear drawbacks. The biggest drawback is the central focus. If the artist performs in the center of the stage - equally from both channels, then when listening fro

  When designing speakers, the objective is for each subsequent model to outperform typical speaker choices or previous TiFi models. Beyond functionality, there's a constant aspiration to craft superior speakers at a more affordable price. A superior speaker contributes to a richer sound image in a real-world environment. Naturally, part of achieving this enhanced sound image involves delivering lower bass tones.

  What to expect from a good speaker? In reality, the question should be, what to expect from a good music playback system, as there are other elements besides the speaker. Traditionally, of course, the weakest link in the chain is the speaker. In any case, a good speaker is necessary for quality music playback.
