I’m always late but this has been another interesting concept to start
thinking about.
MC, I read the ‘World Beyond 20KHz’ article several times and it is very
fascinating to me, especially those hairs. I also very much appreciate the idea
of ‘maybe we’re measuring the wrong stuff’ and feel it has merit. Some things are
probably not measurable (yet) but they do have an effect on the human body’s ‘hearing’
or ‘perception’ of outside sources of sonic energy and otherwise.
I have embraced the subwoofer DBA concept (keeping it low volume, low Hz:
50). Well-integrated multiple subwoofers somehow do open the upper end and give
more air or space (as did a well-integrated REL; DBA is better), but this is not
intuitive for the behavior of a subwoofer. Now, I feel there is very probable merit to
the addition of super tweeters (above 20KHz). And, although not yet known to
us, many listeners report a more defined low end when using them.
Questions: 1: Should the super-tweeter try to start at 20KHz
to avoid the mains? The fact that people report they can ‘hear’ the
super-tweeter makes me fear it is down below 16KHz or so, and if audible,
therefore could interfere with the mains’ own tweeters and probably not in a
good way? I’m guessing ‘inaudible’ is
best. 2:
Is a volume control a must, and going to 100dB volume fine? I think both make sense to have the ability to
match up (and stock 70dB vol seems low…)
I still want a fourth audio sub, but now I’d like to try super-tweeters
too, just unsure about a non-returnable or high-loss gamble, and I feel I have
superb air already with the Raidho sealed ribbon tweeter. I’m just wondering
how much more is out there? I admit DBA helped.
Thanks for another eye-opening topic.
