impedance

J'ai effectué un étalonnage (photo 1) de ma carte son sur mon PC grâce au montage recommandé de mesurer l'impédance d'un haut-parleur. J'ai ensuite fait une mesure d'impédance d'un haut-parleur 3 "et j'obtiens le résultat suivant (photo 2). Je n'ai pas de bosse mais un creux au niveau de la...

I apparently was looking at older documentation that gave the diagram for the test jig for using the sound card inputs and output to build an apparatus for testing driver impedance. I built one using a .1% 100Ω resistor. I also installed a switch to short across the resistor because it said that...

Hi. I'm trying to measure impedance of the speakers found in a Technics SB-EH750 set. My measures: Speaker specs: Internal connection: I'd like to convert the separated cables setup to a single pair setup, and that's why I'm trying to make my own crossover. So, are my measures...

Hi! Thanks for awesome software, but today I have a problem. I'm trying to measure TS parameters of a small driver. However, I get an error "The resonant frequencies of the selected measurements are too close to generate reliable results." I don't know how to solve it. I've measured...

Hello All, so I just wanted to start off on the right foot... and other than the mic check was curious about posting norms regarding 1. advice on a speaker build (driver measurement and how cabinets affect impedance and as a result crossovers) 2. moving this from a hobby to a career 3. got...

Hello, I've been using an impedance tube to measure sound absorption. Following standard ISO/CD 10534-2, I've been using an old 'Soundbook' with Samurai software, and using a periodic noise signal it measures the complex transfer function between two mics in the the tube. To account for phase...
