but simply that all mayn’t cry ’halleluja’ over the sonic outcome of the DBA approach, even after being preconditioned by theory.
You can look at this as theory or fact; works the same regardless: at 80Hz the waveform is about 14 feet long. The ear cannot acknowledge any sound until the entire waveform has passed by the ear. It cannot know the frequency of the bass note until 2 or 3 iterations have occured.
In most rooms, if 80Hz, the wave has met the rear wall and is on its way back by the 3rd iteration. It might cancel the energy of the incoming wave, causing a loss of bass. One important takeaway is that the bass, unless the room is enormous, is entirely reverberant.
That is why a DBA works so well- as long as the subs have no output above 80Hz (otherwise they will draw attention to themselves).
The Classic Audio Loudspeakers T1.5 look like very nice speakers but at $72,000 are pretty steep. In comparison to Wison or Magico speaker they are probably a great value. I have never heard a pair but at that price I would certainly travel to hear them. Which model do you own?
The actual price depends on which options are installed. My speakers are the T-3s. They are custom built (slightly taller) so as to be flat to 20Hz. I have the field coil motors on the midrange, with beryllium diaphragms employing a Kapton surround- so no breakups until about 35KHz. They are quite smooth and the field coils make them as fast as ESLs.
I'm a big fan of field coils- they and ESLs offer speed (and for the same reason- the M.O. uses an external power supplythat isn't available any other way. The ear/brain has a tipping point- if the speed isn't there, the brain moves the music processing from the limbic system to the cerebral cortex- robbing the music of some of its emotional impact.
