use these speakers in my bedroom studio. I found it very useful for my mixing and mastering works. Although there is no acoustic arrangement in my room, they do a good job. especially low mid frequencies are very successful. I can hear very clearly without disturbing high frequencies. the speakers are made of an ideal material quality, I really like the images, it's a quality product. I can say the best that can be bought in this price range. There is a fast transient response, the input level setting on the front and the knobs that you can cut and open the high frequencies are quite high quality and functional, the frequency response at -10 db is in the 46hz-20Khz range, so the low frequency response is quite satisfactory, I don't feel the need for a subwoofer. The only thing I can say negatively is that if you are working at very high dbs, you can feel the air coming out of the front port, also a certain level of limiter is activated. The amp HİSS noise is not at all annoying levels, and if you reduce the input level without having a constant noise sound, the HİSS noise will decrease.
