The speaker cannot be avoided with the amplifier when starting the audio.
Although it is often said in audio, there is a "law of 5, 3, 2" in the proportion of spending money.
Specifically, it seems to be 50% speaker, 30% amplifier, 20% player. In short, speaker performance is the best! Even if you buy a luxury amplifier, it doesn't make much sense if the speaker seems to have low performance. 。 For racing cars, even if a high-performance engine is installed, if there is not enough grip on the tire directly to the road surface, the circuit cannot run fast. Even if the engine (amplifier) is good, if the tire (speaker) is inferior to the road surface (ear), you can not run fast (can not listen with good sound).
In order to enjoy a higher quality music life, it is very important to choose a speaker that suits your purpose. There are various prices and shapes, but make sure to hold down your points firmly.
Speaker Type - How to choose with size and basic shape
Book Shelf Type
As the name "Bookshelf," it is made for speakers that enter the bookshelf, and it is compact and easy to install. There are many relatively small speakers and they are suitable for proximity viewing on desktop. It is ideal to bring the unit to the ear height as much as possible using a stand at the bottom of the speaker. As for the sound quality, there are many types that do not produce bass, but it is a speaker that can enjoy a clear sound with a good three-dimensional feeling.
Floor type
It is a medium-sized or higher speaker used on the floor as it is. It is a speaker in the form that the bookshelf has grown. Because it is large, it takes a place, but it can play widely from bass to wide range, high sound, it is recommended for those who want to make loud volume in a large room, want a full-fledged speaker, but most speakers are quite expensive.
Tall Boy Type
It is a vertical type speaker that does not take much footprint even in the floor type. There is no problem with the installation place, the design is stylish and many attractive speakers. The sound quality can cover a wide range of sounds, and is the most popular speaker of all-purpose type with floor type performance, especially low sound.
A speaker with a hole in the enclosure is called a bus reflex type. From there, the bass is radiated to increase the amount of bass. On the other hand, the sealed type has no holes.
Speaker Specifications
The efficiency of converting power input from amplifier to speaker to sound is called output sound pressure level or efficiency. The figures are from the first half of the to around . The higher this number, the smaller the amplifier output, the louder the sound can be generated. In the past, there were more than 100dB large speakers in order to sound a small vacuum tube amplifier of 2,3W and output at high volume, but now there are various high-power amplifiers other than vacuum tube amplifiers, so high-efficiency speakers are mostly late 80dB around 90dB. When the output is small with a vacuum tube amplifier, a speaker greater than 85 dB is the best choice. In the case of other conditions, it would not be a problem enough to care.
Many speakers have two or more speaker units. This is because it is difficult to play a human audible band (20Hz-20kHz) beautifully in one unit, and it is possible to separate the sound range and make sound. Crossover is the part where the reproduction band of each speaker unit overlaps, and increasing the number of units makes the sound connection unnatural, and because the sound balance becomes poor due to the dispersion of the sound source place, the majority of units are two or three. In addition, although the sound range is narrow, full range speakers using only one unit dare to take natural sound quality and localization are popular. The high-resolution sound source is supported by 40kHz or more high-pitched sounds. The CD is a disc that is roughly recorded only to the extent that a person can listen. A high-resolution sound source is a sound source that contains a wide range of sound ranges over the human audible band (20Hz-20kHz) in detail. I wonder if I got close to the record with my ancestor. Even if the speaker does not correspond, it does not mean that you can not listen to high-resolution sound source, nor does the sound become bad. There are many models with high-pitched range 20kHz even high-priced speakers. This is because it places more importance on how sound can be heard in an audible range in a rich and pleasant way and the output sound pressure level and efficiency.
And finally there is an impedance. The number indicates the size of the electrical resistance and the unit is Ω (ohm), which is almost 4, 6, or 8Ω. The lower the number, the larger the output of the amplifier, but the greater the burden on the amplifier, and in the case of a 4Ω speaker 4Ω it would be safe to use the corresponding amplifier. Speakers with impedance of 6 and 8Ω can be used without worrying about any amplifier.
If you are listening to music and the low sound is not enough, add a subwoofer, which is a bass-only speaker, and if you feel that the treble range is insufficient, adding a high-pitched speaker tweeter to upgrade to your favorite sound is also one of audio fun.
Let's choose the speaker taking into account the combination above, the amplifier used, and the installation space!!
Finally, speakers up to 50,000 yen are priced, but for example, speakers that are small but exceed 100,000 yen will play surprisingly good sound that far exceeds imagination with the design thought and technique that complements the numerical value written in specifications.
