Post Subject: Still "No" to bass horns delayPosted by Romy the Cat on: 7/12/2006
Chris, yes and no. The phase shift 90 degree of there perhaps but it is not really relevant. If we have a very low frequency horn, crossed low with high order crossover and the entire horn is delayed at 30ms then we do not have the same negative impact from PHASES as if it was MF/HF. Make an experiment. Take any MF driver and MF driver and run the LF driver through delay processor. I had 50Hz-crossed LF driver running along with a full range driver…. The delay in 2ms is VERY much auditable in music. The delays of 0.3ms are very auditable with clapping signals. Certainly we would not geometrically align bass-horn (sub 40Hz, do not confuse with 40Hz and up horns) according the mark on sinusoid but it is necessary to align it according subjective auditable effect of delayed arriving. It is kind of hard to differentiate the phase alignment vs. time arriving but I very much see them differently. You could flip 360-degree phase at direct radiator. I know that the wavelength is long but it is differents: phase misalignment and arriving misalignment.. For instance take the 35Hz Edgar Bass horns. If heard them than you seen how “late” they sound and particularly in the orchestral decays when the sound it fading but the bass horn is still hanging behind. I am not saying that anyone should address the arriving delays at ultra LF but if the “Cypriot audiophile Dan” or anyone who go with more or less interesting result should consider it.
