![]() ![]() Next the shallow cabinet depth, again is related to quarter wavelength cancellation, as the depth of the cabinet is less than a quarter wavelength of any frequency reproduced by the woofer and the port position aids the low-frequency extension. Whereas if the reflected off-axis response of the speaker is very different from the directly radiated sound, the ear picks this up immediately as the human ear is more akin to a dual differential device than a pure linear frequency “device”.ģ. When the speaker is close to the room boundaries the frequency response of the near-wall reflection needs to be closely similar to the direct sound from the speaker as this makes the reflected sound “invisible” to the ear as long as the time constant is less than 2.4 milliseconds, which is the ear’s threshold. “Why is this important you may ask? Well, this links into why the corner position works for the AN-E and not for speakers with a narrow baffle. ![]() The benefit is a much better dispersion “window” with the off-axis response being far more even at over 60 degrees off-axis than what is possible in a narrow and deep cabinet.Ģ. This will ensure that the lowest frequency reproduced by the tweeter on the edge is further away from the edge of the cabinet and at the highest frequencies reproduced by the woofer, the edge is closer than a quarter wavelength, thus reducing diffraction and frequency cancellation enormously.
