Loudspeaker technology in general

Hi,

The diligent Dragon-slayer John Watkinson has written with his admirably energetic use of language, about loudspeakers in the Jan/Feb and Mar/Apr (2 most recent) issues of Resolution magazine. Interesting stuff !!
Quite obviously there is an un-conscious side in the human psyche also in auditory perception !!

What is your view and experience regarding those matters (especially the phase-coherence and inter-driver delay coherence) ? (within the theme of general loudspeaker science)

I believe there was that one German company by the name of ***** who made a phase-linear studio-monitor, intended to be able to reproduce the input-signal WAVEFORM (In Watkinson's terminology the "squareish wave") ! And also the Swiss and Dutch have been at it, not forgetting the British and Americans !

How about we Finns ?? (perhaps during the summer ? . . . or winter ?? . . . next life ???)

Lets do it with the future dsp-chips, and leave the remaining dsp-delay for the television-people to take care of, within "lip-sync correction" . . . when and IF that still remains an issue by then :arrow:

All the best
Olli

. . . . just to discuss this theme a bit further, if I may quote the distinguished Alex Garner of Scotland; he has a nice bicycle-analogy describing multi-way loudspeaker functioning and design :

. . . . the importance of stabilizing the "acoustical design axis" of the loudspeaker in the time-dimension should be self-evident.

The Take-Home-Message would thus be (co-axial systems INCLUDED) :

Heureka ! Flat amplitude ! Only time-shift ! (continued on page 2)

. . . . Amazing !

Have a look ! (Thanks Sir Alex !)
