I am looking for a cheap place to purchase YAMAHA audio
equipment.  I have not yet found a mail order house that
is an authorized distributor. I want to stay away from
the gray market goods unauthorized places usually sell.

Anyone out there know where to purchase cheap YAMAHA
audio products ? (preferably by mail).

Perhaps Joeseph Seiler should go back and re-read both his original
post asking, no actually begging that we tell him what we think of his
new system, and also read what Collin Ong wrote.  Mr. Seiler, you did
ask us to let us know what we thought.  Collin Ong asked you if the
speakers you got were the new cheapie Bose speakers.  Cheapie to me
means inexpensive and perhaps implies a general lack of quality.
Don't take it so personally.  He gave his opinion, and that's what you
wanted.  And he is rightly surprised that you got your recommendations
from this net.  There has been quite a bit of badmouthing of both Sony
recievers and Bose speakers.  Your immaturity is surprising.  Are you
really so bothered by what he thinks about your speakers to completely
flame him on the net?  You did get what you asked for... an honest opinion.

	Sure, we all brag a bit, but YOU are the first person I have
come across who really needed to ease up a little.  Maybe the mail you

I have seen no reason for your flames.  Having a bad day perhaps?  Is
your receiver's rear channel not working?  Calm down man.

Yes, a speaker's impedance does vary with frequency. At the resonance 
frequency it can be quite high, and at high frequencies the voice-coil
inductance will cause a rising impedance response characteristic.

I think that the 4-16 ohm classification is a bit misleading as to the
actual performance of the speaker. The dc resistance of a speaker quoted
as being "nominal 8 ohm" is usually 5 to 6 ohms. At resonance it will be
10 to 15 times higher than this, and similarly at high-frequencies due
to the inductance effects.

If the speaker has a 40 ohm dc resistance, then it will not be drawing
much power from the amplifier, so its sound output will be limited.
To compensate for the low sound levels, you will need to turn the volume
up on the amplifier, but this will lead to voltage clipping, especially
if the amplifier is a low-power one with a limited voltage swing 
capability.

If you had a 4 ohm speaker, and your amplifier was rated for 8 ohm speakers
or above, then you would probably find that it would not be able to meet
all the current demands of the speaker when played at high power levels.
This leads to current limiting protection circuitry in the amplifier
being activated. Running an amplifier at high power levels into a load
below its rated impedance can also cause overheating to occur.

If you range is $1500/2000 a pair, take a look at the Theil's.

The 1.2's cost under $1300 and are about the best 2-way I have ever
heard.  If you like imaging and transparent mids and highs, you simply
MUST listen to these.

If you can break the top of your budget to about $2200, listen to the
Theil 2.2's.  When driven by a good (warm) mosfet or TUBE amps these are
the best dynamic speakers (barring the WAMM's) that I have ever heard. 
They not only maintain the 1.2's fantastic mid's and high's, but add
some of the most powerful, tight bass you are likely to hear out of a
speaker smaller than an economy car.

The Apogee's are great speakers, as long as you don't like to move while
you are listening to music.  Listening to the Centaurs, I stood up and
the sweet spot disappeared, the music sounded awful.  The Theils sweet
spot isn't huge, but it's a hell of a lot bigger.

Just MHO.

Maybe one of these mags. had an article also, but there is one in the
current Electronic Musician.  It's informative on an introductory level,
but they make no judgments about the various systems.

I personally have only heard Dolby Surround (off of Switched-On Bach
2000) and Q-sound (off of Sting and Madonna's albums) and they both have
their strong points.  But these were specifically recorded with 3-D sound
equipment.  If you take a mono or stereo signal and try to make it "3-D",
there's really only so much you can do with the signal, so I would have
my doubts about the effect of these kind of boxes.  Still, I'd love to
hear one.

I was thinking of using this for the hell of it: but where do I get twin-ax
and suitable connectors? The only decent twin ax I've seen was mil-surplus
and fairly skinny, about 7mm OD. The only connectors I've seen were
humungous, 25 mm diameter, to take 15mm OD cable.

In any case, I suspect twin-ax doesn't help unless you have a balanced
driver on the transport: I dont feel like building one just now, thanks.

   If you want a classical piece with nice dynamics, try Stravinsky's

I believe (I'm not sure about this, but I read somewhere for some formula) that
teh calculated value of the enclosure includes 10% for bracing and such.
(Crossovers, wire, speaker?)

I recently built a set of speakers for home use.  I thought I'd share the
experience with the net for the benefit of others.  Please, be mature if you
are going to critique what I have built, and remember what I paid for it.

I say this catalog laying around in my bosses office.  It was an MCM catalog.  
Then I noticed their wide offering of drivers in the middle (about ten pages
worth).  Since I was reading all the discussions about enclosures here last year
and ftp'ing the box design software from some site I don't remember, I decided
to build my own speakers.  I got a set of Eminance 10" woofers and a set of 
Pioneer Tweets.  A 12dB/Oct Crossover, a rightly tuned port, and some terminals,
and I was set.  The only problem, it took MCM almost six weeks to get me the 
stuff, since the woofers were on backorder.  So they came in, I built the boxes
according to the design program I used, and then listened.  Wow, I never thought
a project like this could turn out something useful.  These speakers sound
great!!  I only paid $120 for the components, and $10 for a sheet of 3/4"
particle board, and a little bit for supplies, and I have speakers that will
walk all over any speaker for lees than $200/pair.  They are a little heavy 
3/4" particle board has a way of being that. (40 lbs apiece, i Guess)

But anyways, the moral of the story, those equations work.  The frequency 
response is as flat as a board, as promised.  Well, I just thought I might
share.  For all those that want to know.

BTW, MCM is a good catalog, and their helpline people are pretty good too.

This may not be the correct newsgroup for this question, but during a
(fairly casual) search I couldn't come up with a better alternative.

I'm a university student and I can't afford to buy the kind of HiFi
system that I want, so I have decided to build it.  The cost is
(hopefully) lower, but more importantly, spred out over a longer
period of time.  From what I've understood, valve amps use simpler
circuit designs than transistor or integrated circuit amps, plus I
love the sound I've heard from the valve amps I've listened to.

What I need is pointers to books or magazines from which I can learn
the audio electronics needed to start building valve amps.  I thought
I'd start out easy and get a simple something that works, before I
build the X2000-A4 150W class A valve amp of my dreams... :)

I've studied some basic electronics here at the university, but I
can't remember much about it, nor am I particularly adept at
mathematics.  If there is a good book that teaches audio electronics
from the basics, I'd be very interested indeed in reading it.

I primarily intend to play CDs, so I thought that I could settle for a
descent class A valve power amp and between the CD and the amp I'd use
a simple attenuator and buffer.  I have some designs for this that I
could use.  However, I'm interested in learning about pre-amp design
too, since I do have an old trusty 'vinyl lathe'.

In the US, the Sony D3 Dat Walkman costs from $500 to $600 typically.
Other portable dats cost in that range and up.  Home dat decks start

Summary: Putting one resister across speaker terminal

Date: Fri, 16 Oct 1992 15:24:25 GMT

Hi Speaker Builders,

  Recently, I made a pair of 2-way speakers (completely my own design).
First the input impedance varies a lot across frequency bandwidth
(from 8-32 Ohm) with two peaks : one at woofer in-box resonance
frequency and the other at crossover frequency. This is normal in
most design. However, I was curious about making the input impedance
look flatter so I tried putting a 10 Ohm resister across terminal of
each of the speaker. The impedance became +/- 2 Ohm across the whole
frequency range (averaged about 4.5 Ohm). A 8-Ohm speaker pair has
become a 4-Ohm one since then because I observed a dramatic improvement
with this modification. The sound became more open in both high and low
end of the frequency range. I can feel the deeper bass and the detail
that I hadn't heard with this speaker before and without an introduction
of harshness.
  Well, may be my ears are having problem. So I would like to ask for
validation from any of you who has had experience or be able to explain
why this happens. I personally believe this is a interaction effect
between amplifier and speaker. Any comment will be appreciated.

Thanks,
