AR-MST measurements

Recommended Posts

Risposta in frequenza in camera anecoica = Anechoic Response. It shows some irregularities especially at about 2500, 6000, 14000 Hz because of the destructive interferences at the microphone position caused by the use of 4 tweeters. See also the polar responses. 
Risposta in camera d'ascolto rilevata con "rumore rosa" attraverso filtri a terzi d'ottava = Room Response measured with pink noise through 1/3 Octave filters. 
Diagrammi polari = Polar Responses
(note that they are not so regular. Unfortunately 4 tweeters cause a lot of constructive and destructive interferences. In other words, waves with the same frequency emitted by different drivers combine and add together or cancel depending on their phase at the point where they combine).
Curva d'impedenza = Impedance 
Risposta ai transitori = Tone Bursts 




DISTORSIONE ARMONICA = ARMONIC DISTORTION at 90 and 95 dB ( the II and III armonic distortions are actually measured at 90 and 95 dB only at 500 Hz . At the other frequencies the real SPL depends on the frequency response of each loudspeaker); the tables show the III and II armonic distortion for all the loudspeakers tested in that issue of the magazine. 
Numbers out of parenthesis are III armonic distortion. 
Numbers in parenthesis are II armonic distortion. 
Vin= Voltage employed to obtain 90 and 95 dB at 500 Hz
