Discover the technical advantages of our loudspeaker series.<\/h3>\n\n\n\n

At first glance, measurement results may seem somewhat dull, yet they reveal a great deal about the quality and significance of a product or process. It is precisely through carefully recorded measurement data that important conclusions can be drawn\u2014conclusions that are ultimately crucial for evaluation and improvement.<\/p>\n<\/div>\n<\/div>\n\n\n\n

While the phase response without FIR support is quite constant and rolls off gently but it spans more than three complete phase cycles \u2014 a total shift of over 1,000 degrees , which is to much <\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n\n\n\n

With FIR filter correction, the frequency response is significantly smoothed; it fluctuates by approximately +\/- 1 dB above 100 Hz only. The range extends from 15 Hz to over 20 kHz. The AMT's amplitude peak has been completely \"smoothed\".<\/h3>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

FIR corrections allow for a noticeable reduction in distortion. In the bass range, it drops to approximately 1%, while in the high-frequency range, distortion falls to about 0.3%\u2014based on a slightly lower overall level of just under 92 dB (100%).<\/h3>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
