It jsut depends where the laser is located on your cd player as to how you
place the cd.
Take a look at your boombox and see if you can see the laser (Not the beam)
but where the beem comes from.  If your boombox has a tray and you are unable
to on your boombox try to find a portable CD player and you should be able to

Write your reply.

assistant: Hi all,
I have been following this echo for some time now (yes, all the way from
Sydney!) with increasing frustration at the car audio vs home audio debate (I
enjoy both).  In a vain attempt to distract everyone with a question,  I was
wondering if anyone could help answer the following about my home theatre set
up.
1.  I have a pair of small 2 way vented speakers as my mains in my home set
up and a single sealed 12inch sub running via a small dedicated amp from the
low pass output of the Yamaha Pro Logic decoder (VSX1050).  Even though the
main speakers are not particularly "bass heavy" do I need to run some sort of
high pass filter on them to prevent interference from the sub?  If so, how?
2.  The lowpass output of the decoder has an Fc of 400HZ and there are lots
of directional clues coming from the sub - what is the best Fc to use and how
do I do this  - at line level (before the amp) or at speaker level?
3.  I want to replace the dedicated amp I have with one built into the sub
box itself - does anyone have a good cheap amp design (about 100Watts) I can
work with?  It seems the power supply requirements are more expensive than
the active components on most of the kits I have seen.  A decent 200VA
transformer runs to about $80 here.
4.  Lastly (is this off topic Bonnie?) How do the commercial sub
manufacturers get their subs to turn off after 10 minutes or so of
inactivity.  I keep forgetting to turn mine off and its driving me nuts!
Thanks in advance.

assistant: Hi Dan!
Good simple, easily understood way of putting this, Dan! I was planning
a much more long winded discussion on this, which is now totally
unnecessary!
I was getting concerned with the DC resistance messages being equated
directly with the impedance (AC). Ohmmeters are best used to check if
the voice coil has a complete circuit or has been broken, but is not
otherwise directly related to impedance except as your rule of thumb
stated above, which seems to be true from my experience, also.

Write your reply.

assistant: Well, in my experience, I would say that the best way is to cut
off before the amp (that is, if it is being used ONLY on the sub) so
that the amp sees only those freqs below the cutoff point.  This will
make the amp run easier.  I am more of a pro-audio person so when I
hear the term "sub-woofer", I immediately think "below 125Hz".  More and
more home systems are employing techniques that the pro-audio field has
used for years.  When I think of sub-woofer, I think of something that
is crossed over at no higher than 125Hz and whose real "hump" is from
about 50-63Hz.  Those directional clues are because of the high cutoff.
400Hz is damn near A-440, which if you don't know, is the open 5th
string (2nd lowest) on a guitar and is definitely a directional freq.
The lowpass output could actually be more accurately termed "midpass",
though a true midpass filter would probably have a second cutoff point
in the area of 1.25-2.5kHz.
        Anyway, my suggestion would be to cutoff before the amp.  In
your situation, I would say no higher than 200Hz, but lower if possible.
        Hope this helps...

Write your reply.

assistant: Gives 10dB noise reduction above 3Khz on a sliding scale upwards.
Gives 20dB noise reduction more or less broad band.  (this is an
approximation)  Above a certain threshold compression and exansion take
place that doesn't take place in B type Dolby to add to the headroom and
cut down on saturation of the tape at higher recording levels.
The above two systems ABSOLUTLY REQUIRE that the tape be accuratly
calibrated to the machine in question to prevent losses during
record/playback.  Levels & EQ both must be precise.
Dynamically alters the AC bias applied to the record head during
recording to compensate for higher audio frequencies acting as "bias"
for lower frequencies.  Also dramatically improves headroom at higher
record levels.
Multi channel usage for movies etc.  Someone else could probably expound
on this better. :-)
Dolby dynamically alters the frequency response and level during record
to boost low-level sounds.  A complementry cut back takes place during
play.  Hence the noise goes down with it.
Nice thought. :-)  There is methods in the CD decoding to deal with
minor rotational problems.
The CD rotates at roughly 500 rpm at the start as it is read from centre
to outside edge.  At the outer diameters, the speed is 200 rpm.  This is
done to ensure the data that comes off the disc is at the proper rate.
Portable CD Players with the memory feature tend to double this rotation
speed and plow the cd music into a memory so the memory contents can be
"played" during bumps etc.
Hope the above is of assistance.

Write your reply.

assistant: I am far, far, far from being knowledgable about ANYTHING digital, but
in thinking your reply through, it would seem that the rotation speed is the
same for the inside edge of the CD as it is for the outside edge. When point
A
of the disk interior edge passes a stationary point off the disk 500 times in
a minute, so would point B on the exterior edge.
       My laymans logic would think the difference is the amount of digital
data read from the inside track versus the outside track would be very
different, with the exterior providing more data than the interior, provided
it was given data at the same density (wrong term?).
       Where am I missing the boat?
Thanks, John

user: You are replying to Kurt J. Tischer about "Home Subwoofers".

Write your reply.

assistant: Cutoffs/crossovers for home subwoofers should depend entirely on the
speaker system of the user and his listening room. While good quality
bookshelf speakers in a large listening area will often call for a cutoff in
the 125 MHz area that you mentioned, many full range towers sound best when
cutoff at some point much lower.
        In my case, depending upon the source material, 40 to 50Mhz has the
most accurate and pleasing effect, while my friend across the street MUST
have his set at 80Mhz simply due to room measurement differences. I am glad I
am not much of a gambler, as I would have lost the deed to the ranch on that
one!
Where I have a steeply sloped cathedral ceiling and about 6 ft deeper area,
he has an 8'2" flat ceiling and a slightly narrower and less deep room. Same
full range speakers. Never would have thought that big a difference would
jump out like that.

Glad to see you and New Zealand back with us again. Now just wish we
could get the Hong Kong crowd back in here again. They REALLY were
into the high end home stuff! We missed all of you.
No, I don't believe that you will need to bother. The small mains
probably have a built in high pass due to the nature of cabinet size,
et al. A lower sub frequency crossover Fc could leave a hole in
frequency response coverage on that system. Locate the sub at the
center front location, which will minimize the displacement effects
since it's coming from the "window on the wall" is a more natural
direction for that band of bass.
That Fc does sound much too high... but then you didn't say just what the
response of those main speakers are, and I agree, directional info is there.
Subs work best below about 200Hz where the fundamental frequencies made
by the source material reproduce as pressure changes in the room and are
nondirectional and diffuse, even throughout the room except where room
node cancellations cause the sound to wink out which needs room treatment
to cure.
My current "main studio monitors(and keyboard gig/personal sound system",
if needed)" starts to fade at 120Hz (3db down point and loses about 6dB
