Subject: Cross-over question
Date: 29 Sep 92 18:15:21 GMT
Organization: Software Engineering Institute

I need help choosing which frequency at which to cross-over my woofer.
I purchased a pair of KLH speakers for $200 last week. I decided to open them
up and take a look at the innards only to find: A) No acoustic insulation
                                                B) No cross-over( Only caps)
                                                C) 10,000 gauge wire!!!
I went to Radio Shack and bought Insulation, two 3-way crossovers, and already
have an abundance of heavy speaker wire. There are 2 different settings for
the woofer cross-over frequency 1600hz and 800hz. Which would be the ideal
setting? Taking into consideration that this isn't a sub-woofer, at least I
don't think it is because of it's, less than microscopic, magnet size.

I listen to a wide variety of music from Harry Connick Jr. to Public Enemy if
that will help any. 

Please respond ASAP. I leave here at 4:00 pm

I have a DMX box, and the sound is pretty mediocre, about what one would
expect from a bottom of the line CD player.  This doesn't have much bearing
on the value of the compression scheme however, because they seem to have
produced the box about as cheaply as they could get away with.  I've heard
that it sounds much better with a good external DAC, which I will eventually
obtain.  Speaking of which, does anyone have any experience with the QED DAC
which sells for $300?  Seems almost too good a deal to be true :-).

For all you golden ears and non-golden ears out there.

With all this talk about audibility of cable effects that can't be
measured, let's talk about measurable audible effects.

Why does that AM car radio sound so good after weeks in the wilderness?

Why does a high end audio system sound better through an open door
where you are outside the stereo image of the speakers?

Who in this group can here if the speakers are reversed polarity?
    what are these audible effects.

What if only one speaker has polarity reversed?

Can you tell if your speakers are matched pair?

Can you tell if the drivers are time aligned(phase coherent)?

Is the flat response/ perfect measurement speaker really desired?
             Sound production vs sound reproduction

Why does a shower with terrible acoustics by sound reproduction standards
     sound so good?

Seems people can't even agree on the audibility of measurable effects!

Oh darn it!   Does that mean I am going to have ship my pre-recorded

(But I will admit these are the ONLY ones I saw so I decided to buy a

I am withholding judgement on both of these until they have been out a
couple of years.    I have seen too many music/audio formats being

in a couple of years.

I was wondering if anyone could provide me with information on the two
components made by New York Audio Labs - the Moscode Minuet Preamp, and
the Moscode 150 Amp... both are tube models, and I think I have a chance
to get a decent deal on both.  I have heard that each has a current used
market value of $200 - does this sound accurate?
 
I am currently using an Adcom GTP-400 and an SAE A205 (the DAK amp).
How would the NYAL stuff compare... also, how reliable is it, and what
would it cost to retube the two components (and how often would this be
necessary?).. I have heard that NYAL is now no longer, so I'm a bit
worried about availability of parts/tubes/service, etc.  ANY help,
opinions, etc would be deeply appreciated!  Thanks..
 
Oh yes, my speakers are Klipsch KG4's.

I suspect that I have the most sensitive listening situation that can
be found anywhere in the world at the moment.  Anyone wanting further
details might send me a postal and an email address, and I might be
able to send you a reprint of an invited paper that I presented at the AES
in the UK in September 92. There was nothing "casual" about our test,
and even audiophiles who normally eschew "blind" testing were
impressed.  This was NOT DCC, but perceptual codecs that use related
algorithms.

	First some background.  I've been subscribing to 
Speaker Builder for a few years and I've been planning
to build some new speakers as soon as the time and the 
money come together.  Well this week I got a catalog from
a place called North Creek which claims to sell the "best"
components available.  They claim to sell the best inductors,
resistors, capacitors, and drivers available.  Most of
these parts are "mil-spec" components.  (I guess that
we're finally seeing some consumer applications for all 
that research ;-} ).

	My question is if anybody has dealt with North Creek?
Has anybody built anything (cross-overs, speakers) with
their components.

	Another company that I've been looking at for some
speakers is Gold Sound.  Nice range of speaker kits and
Speaker Builder has mentioned them kindly in the past.

Naw...What about WEA (Warner/Elektra/Atlantic{/Reprise/Sire/Atco/East-West/

Time-Warner conglomerate, which is still decidedly American.

But you're right, the rest of the majors are now foreign owned:

MCA/Geffen/GRP: Matsushita (Japanese)
Columbia/Epic/Masterworks: Sony (Japanese)
Capitol/Chrysalis/Virgin/Charisma/Caroline/Blue Note: EMI (English)

        London/Motown/resurrected-label-of-the-week: Polygram (Dutch)
RCA/Novus/Arista/BMG/Windham Hill/etc.: BMG (German)

The one other major minor that remains under US control is Fantasy
(Fantasy/Galaxy/Prestige/Riverside/Stax/Specialty/HDH/etc.), which was 
almost sold to Polygram earlier this year.

(And, of course, the above list omits the monikers of other significant
companies that were previously absorbed by the above majors: Decca,
Uni, ABC, Paramount, 20th Century, MGM, Impulse, etc.)

I've built some board level amp kits in the past, the manufacturers are
all long since defunct, and had very good success with them. There seem
to be lots to choose from. For bass (I'm a bass player) the main concern
is power. Also consider designing your own, especially if you are Biamping
and only looking to drive < 1KHz, you can get REAL sloppy and still have
something that sounds fine.

points to consider:

 - Are you confident that you completely understand all the grounding
   issues? (Read my latest anecdote in rec.audio.pro!)
 - Be certain to build it into a strong case with lots of solid
   mechanical connections (good connectors internally, cable routing
   systems...) so that something doesn't come loose while hauling the
   amp around.
 - how's your electronics basics? If you can't tune a simple filter
   circuit or set a bias level then make certain you know someone
   who can.

If all of the above is OK then ignore Chris and go for it! You'll have
the flexibility to tune the amp to your requirements. That has been
a useful feature to me. If you are a little skeptical of your abilities
then Chris's suggestion is a good one. There are plenty of good and
reasonably cheap power amps out there suitable for bass, especially in
the used market.

A Possible Source For Amp Kits:

I have seen an advertizement that may be usefull. I have not dealt with
these folks so I have NO HISTORY. I have seen them advertized for about
five years, that's a good sign.  Mark V Electronics
(800) 423-3483 "for orders", (213) 888-8988 "for catalogs & info"
(213) 888-6868 FAX
They have a 300 watt MOSFET amp for about $80. The transformer is $42
and add two 10,000MFD filter caps at $22 each. Another $35 for a rack
mount cabinet and say $25 for other parts. So you could put it all
together for about $225. These prices are from an add that is a couple
of years old so the prices are likely to have changed.

Anybody dealt with these guys before?

How old are your output valves? Try to exchange the power valves from right

Organization: CliniCom Incorporated, Boulder, CO
X-Newsreader: Tin 1.1 PL4


In reference to the question of what the difference is between Sony's
regular CD players and their ES CD player line I have some basic thoughts.

I recently purchased Sony's X555ES single disk CD player after having demoed
Sony's bottom-of-the-line? ES player, the X111ES. The ES line from Sony
typically tends to employ better components (quality) than their mass-market
counterparts.

If you were to lift a Sony ES component and then a mass-market component you
would notice a great difference in weight.  The difference is due directly to
the construction and the parts used (sapphire bearings, composite frames, etc)

I noticed a difference between the two ES players...  If you don't notice a
big enough difference between two CD players then buy the cheaper one.  
Although sometimes a higher price is justified in better workmanship.

I would also recommend a single disk player for better sound quality at
comparative prices.

I hope this has helped...  Any questions mail me.
