Below are some of what you get from a speaker frequency response test software: Waveform generator: One of the most important aspects of speaker measurement software is to pass sine waves through it. With a top speaker frequency response test app, you get a waveform generator that makes the t...
The speaker test system is an efficient test solution developed by us specifically for speaker production control. When used with our speaker test software, it can stably and quickly test the frequency response, distortion, Rub & Buzz, Impedance, F0 and other parameters of the speakers. The soft...
5.FrequencyResponse(頻率響應)頻率響應(FrequencyResponse)就是實效頻寬(EfeectiveFrequeneyBand)的有效範圍，通常是從低音諧振(fo)到高音域的有效部份。如圖5所示，是fo(120Hz)~20kHz，但是到20kHz的SPL已減低到85dB，如按高音域的高峰計算，當為120Hz~18,000Hz。一般說來，實效頻寬的峰面平坦者為佳(如圖5)，...
Except for room response, most speaker measurements are made with the Audio Precision System One, a versatile digital test instrument. Attaining the speaker's composite corrected frequency response; Each speaker's impedance plotted as a function of frequency; Woofer distortion; Group delay; ...

Toe-in will also change the tonal balance; specifically the sound will be brighter with toe-in. And keep in mind that some speakers are designed for flattest frequency response with no toe-in. These speakers should be positioned according to the manufacturer’s guidance, with no toe-in. ...
We conduct our soundstage test at the same time as the frequency response and dynamics tests. We use a room that's 20' (L) x 16' (W) x 9.5' (H). There's one couch in the room. We use some acoustic treatment, namely, a few acoustic panels to reduce noise levels and echo in ...
