89.0. "DIGITAL SOUND" by DREAMS::HAYNES () Mon Mar 04 1985 15:41

	IN A ADD I READ A COUPLE OF DAYS AGO IT SAID"WHY WASTE THE
PERFECTION OF DIGITAL ON THE IMPERFECTION OF A CONVENTIONAL SPEAKER?"
	WHAT I WAS WONDERING IS IF THESE DIGITAL SOUND SPEAKERS ARE
AS GOOD AS THEY SAY THEY ARE. I'VE RECENTLY BOUGHT A PAIR OF KLIPSCH
SPEAKERS AND THE YAMAHA CD-2.I'VE NEVER LISTENED TO THE DIGITAL SPEAKERS
ANY INPUT ABOUT THEM WOULD BE HELPFUL

Too often people become nervous at manufacturers claims of significant audio
equipment breakthroughs.  Just because Sony (and I am guessing that this is
the advertisement in question) claims that a square driver improves dispersion
and clairity does by no means make it true.

Now they can show you all the computer-generated bull-sheet, and tell you about
the incredible dynamic range of the digital audio systems comming out, but when
it all comes down to the real thing, they (the manufacturers) are constantly
trying to get you (the consumer) to sell all your old equipment, and stay in
the state-of-the-art lane (as they define it).

The tool, use intimidating advertisement to make you think that your gear is
now obsolete.

But the proof is in the listening.  I can generate sine waves
all day, but if a speaker does not image well, or present a solid sound-stage,
it just plane doesn't.

So the moral is, unless you are dissatisfied with what you have, hang on to
it.

I have learned to separate advertisement breakthroughs from legitimate ones,
and take the latter with a grain of salt.

Just out of curiosity, Jon, what model Klipsches did you buy?

Nice speakers, Jon.  I would not worry about them being able to "take it"...

I saw some adds based on the theme mentioned in .0, but they were not
for digital speakers.

The last thing I heard was that Bell Labs was working on them.  Now,
Bell Labs has a tradition of doing good things, but don't expect these
digital speakers to end up on any stereo system.  Voice phone lines
are bandwidth limited to 300 to 3000 Hz (I think) and that was the
range of sounds they were trying to reproduce -- and they hadn't
reached that level yet.  How often do you enjoy listening to music
over a "voice quality" phone line.

If anyone knows anything more about digital speakers, specially if
you know of research in hi-fi digital speakers, please correct me.

Me thinks that there in some confusion here.  When these guys
(the manufacturers) say digital speakers, they don't mean that the speakers
can take raw binary information, and produce sound, they are talking about
speakers that are of the conventional design, but they claim that they
can "better handle" the dynamic range of the CD format.

This further backs up my long talk about an advertisement breakthrough.  I'll
be willing to bet that some folks think that the speakers can do somthing that
ordinary speakers can't.  Not true.

What they do is put square drivers, or orange color, or * and claim superiority.

  what comes out the back of you cd player is analogue, so digital
  speakers are going to be useless!!!    :-)

   Of course we shant forget about B&W making the Professional Digital Rock &
   Roll Studio Monitors.  It seems that Rock Studio's needed a Monitor that
   could really let them know what the Digital master tapes sounded like.  
   Using computers with laser intersomethingorother they 'redesigned' they
   808's( or something ) into the 808s (?).  These new monitors were supposed
   to be able to reproduce from 10 (ten)Hz up to 30,000Hz +-1db.

   There was no maximum power rating and the max db was 124.  Thats pretty
   loud.  124db of serious rock and roll can kill.  Imagine listening to
   'The Wall' or 'Dark Side of the Moon' at 124 db digitally remastered....

      waiting for the worms your honor.........
