There are a lot of audio enthusiasts who like British sounds. There are also many people who are full of doubts about how to better match the equipment after buying the speakers. Some netizens mentioned that the ATC speakers in the UK are not good for matching amplifiers because they are online. It is impossible to say that some people say that ATC SCM19 speakers are not more than 50,000 RMB, but some people disagree. It is said that the Krell S300i with a price of more than 10,000 can be pushed well...so.
If you have a pair of ATC19, what amp will you choose? And what brand of amp sound is clear, meticulous, sweet, shiny and transparent, the sound field is huge, the penetrating power is strong, the wall is over the wall, the low frequency is solid... (this requires a lot)
What is the attitude of Mr. Liu Hansheng from Taiwan on the matching of these small boxes? ATC SCM19 is just a pair of small bookshelf speakers, but the above users demand it as if it is a pair of SCM300! This pair of small speakers weighing only 9 kg, a 25mm tweeter, and a 150mm mid-woofer unit should not have any non-partition requirements, otherwise they will be disappointed.
The sensitivity of the SCM19 is only 85dB, and the bandwidth is 54Hz-22kHz. As a speaker in a small room, it can make a fairly balanced sound. In my own experience of using ATC speakers for a long time, its high frequency band is not too high, and the gloss and sweetness are enough. If you don't let it work too much in the middle and low frequency bands, you can also achieve the balance of high, medium and low frequency bands. At the right volume, it will be a pair of balanced speakers, resistant to hearing, warm, and nothing.
If in my experience, it is not bad with the Krell amplifier, the high frequency band and the middle frequency band will be slightly more lively, and the Pass will be more solid. However, this must also take into account the tonality of the listening space, is it hard or soft, or moderate? If it is hard-tuned, there will be more high-frequency reflections, which is not suitable for amplifiers with high-frequency external amplifiers. If it is soft, what amplifiers will not be bad.
It should be noted that do not think that ATC, a small speaker, needs a high-power amplifier to force the low-frequency sense. The small-caliber mid-low frequency unit has its limitations, and it is responsible for all frequency domains below 2.8 kHz. If you are too urging, not only the low frequency band is barely distorted, but also the mid-range is the same, so it is not good.
In short, the small speaker has a good volume to listen to, so don't think it can show the power.
The amplifier with high frequency and intermediate frequency is better matched with ATC! The average person thinks that ATC needs high power because the sound of the ATC tweeter is restrained, causing the high frequency band to be insufficient. In addition, I want to have more low frequencies on the small unit, so I am crazy to drive the ATC small speakers. If it is a large speaker with ATC 100 or higher, it will require a larger output power.
