Don’t worry about choosing a speaker？

Are you always confused by parameters when buying speakers? Worried about spending a lot of money to buy a product that sounds good? In fact, when choosing a speaker, there is no need to fixate on complex terminology. By grasping the core requirements and three key steps, even beginners can accurately step on the center head.
Step 1: First, clarify "where to use". Requirements determine the direction, and the requirements for speakers vary greatly in different scenarios. First, think about "how to use" and then choose the type:
• Home listening to music/watching movies: prioritize "bookshelf box" or "floor box". The bookshelf box has a small volume and is suitable for small living rooms/bedrooms. When paired with an amplifier, the sound quality is delicate; The floor box comes with a built-in subwoofer, eliminating the need for an additional subwoofer, providing a spacious atmosphere. 
Desktop office/gaming: Select "Desktop Monitor Speaker" or "Multimedia Speaker". The monitoring speaker has high fidelity and is suitable for listening to music and making simple audio; The small speaker comes with USB power supply and can be used by plugging it into a computer, with high cost-effectiveness. 
Outdoor/portable use: Lock the "Bluetooth portable speaker". Focus on battery life (at least 6 hours), waterproof rating (IPX5 or above to prevent splashing), and the smaller the size, the more convenient it is to carry, suitable for camping and picnicking. 
Step 2: Focus on the three key parameters, don't be fooled by false labels, don't need to understand too many technical terms, remember the three core parameters, and you can avoid 80% of the pitfalls:
1. Power: Don't just look at "peak power", focus on "rated power". Choose 20-50W for home desktop and 50-100W for living room floor, the power should be sufficient to prevent the sound from becoming weak. 
2. Frequency response range: the lower the better? not always. What the human ear can hear is 20Hz-20kHz, and the frequency response of the speaker covering this range is sufficient. Household speakers labeled as "50Hz-20kHz" are more realistic than those labeled as "20Hz" (they dive too deep at low frequencies, causing them to explode in small spaces). 
3. Impedance: Ordinary users can choose "4 Ω or 8 Ω". Impedance and amplifier matching (such as a 4 Ω speaker paired with a 4 Ω output amplifier) ensures that the sound quality is not compromised. Novices can simply choose styles labeled as "compatible with most devices". Step 3: It is necessary to "listen in", and the ear is more reliable than the parameters. Parameters are the reference, and ultimately it depends on the ear to judge. During the trial listening, pay attention to three details:
• Clear vocal performance: Play a vocal song (such as folk or pop) and listen to the singer's voice to see if it is "close to the ear" without any noise or excessive nasal sounds. 
• Whether the bass is clean: Play a song with low frequencies (such as rock, electronic) and feel if the bass is "elastic", not a "rumbling" sound stuck in the box (stuffiness=low frequency turbidity, no matter how expensive it is, don't buy it).
Whether the sound field is open: Listening to symphonies or live songs, feel whether the sound has a "sense of space", not crowded on one point, so that watching movies and listening to music can be more immersive.
