Your current speakers with the TAD TM-1201H midbass push enough energy into the room to give the illusion that a 200lb physical body is singing in the room. "That is not the horn you are looking for", said Obi-Wan.Ī Man of Character marries one woman for life, but fools around with several different speakers The stereo illusion is just a Jedi mind trick anyway.
Many multi-horn speaker designs seem willing to accept a known "crazy tweeter placement" in favor of 2" compression driver dynamics on a large horn. It is necessary(but not sufficient) for a speaker to measure good to sound good. Geddes has performed extensive measurements on controlled directivity and polar response to educate why his Summa OS-waveguide speakers use just a 1" diameter compression driver. If you run a sinewave on a multi-horn around the Xover frequency and walk around your room comb filtering will generate SPL peaks and valleys.ĭr. The main reason a low-height horn/waveguide like the SEOS is recommended with a large diameter midbass like your TAD TM-1201H is to minimize the center-to-center spacing in an effort to limit lobing(comb filtering).
A crossover cannot remove the break-up mode distortion or the high frequency beaming common from a 4" diameter diaphragm. If you run a s-l-o-w sweep of sine waves from 5KHz to 20Khz you should be able to hear: attenuation diaphragm break-up modes beaming from the large diameter diaphragm and phase plug limitations.
