PC Speaker System Question

I have a _powered_ speaker system on my PC, only labeling on it is...

G-1050 Multimedia Speaker System

Main unit is the "bass" with leads to power two external treble units.

I'm not even sure where I got it... probably came with some PC
purchase and set on the shelf for some time ;-)

Anyone know what's in these things?

Do you think I can drive two monitor speaker sets, or will that be too
much load?

Nothing to be proud of.

*Monitor* speakers ????????? !!!!!!!!!!!!!!!!!!!

Are you talking about the sound card driving two sets of amplified
speakers? I do it fairly often, when testing donated speakers before I
pass them on. I found some stereo "y" cables at the local dollar tree
and bought several for a buck each. One of the "Y" cables, and a
headphone extension cable let me test speakers without reaching behind
the computer. The amps are line in, so there is a slight change in
level.

Yes, there is a DSP thing that substitutes the correct words.

If they are made like the no-name powered speakers
that came with my PC, what's inside is crap.

When mine died, I opened it up to repair it. The 'lytics
were under rated, regulation was non-existant, heat
sink was inadequate, there was no venting, and construction
was shoddy.

I'm not sure what you mean quite frankly. Do you mean can you add more
'powered speakers' in parallel driven from the sound card's line-out ? Yes.

Can you use these speakers to drive more passive speaker cabinets ? Very
unwise.

This is pretty much the norm for computer speakers and the speaker units
themselves are often very inferior too.

The audio chips are pretty crappy for good measure and their published power
ratings make the vendors of ICE sound positively truthful !

You simnply don't get 650W active speakers of any quality For $29.95.

Hello Jim,

You may not want to open it. Could drive tear into your eyes. It is
deplorable what counts as electrolytic caps these days. Makes a
transistor radio look like a mil spec device.

Mine is similar and from Boston Acoustics, a bit better than the
"systems" of today but even there the electrolytics seem to be fading.

Do you think I can drive two monitor speaker sets, or will that be too
much load?

If they are both the usual coil speakers of similar impedance it should.
Just give it a try. The sound might not be so great since the little
treble speakers have to frequency response in the bass range while the
monitor speakers prbably do.

650W is really watt/hours. You get 5 watts out for about a week before they
blow up.

I bet the box they came in claimed them to be 20000W. I actually saw
this in some computer store or another. Everyone around looked funny at
me as I let out a big whooping laugh.

You can't get more than 1500W out of one outlet. Perhaps that is Chinglish
for 20,000 milliwatts.

Anyone know what's in these things?

Consumer line-level analog input,
line-level crossover (combined LF to the "bass"
part, and HF to each L&R part.)
three ultra-cheap power amplifiers
small "subwoofer" in the "bass" unit,
two tiny speakers for the "satellites"

These things typically suffer from all the problems
you can guess just from looking at them. They usually
have a big "hole" between the upper end of the "bass"
unit and the lower end of the external "treble" speakers.
Do you think I can drive two monitor speaker sets,
or will that be too much load?

Unlikely to be worth the exercise. The outputs are power-
limited, frequency-limited, and maybe even frequency-
shaped to compliment the speakers. Possibly even designed
for a wierd impedance, as well. They were meant to be
used as a set (or not at all, as many of us perfer).

Those plastic "computer speakers" are pretty reliably junk
across the board, at least by conventional audio standards.
Even the "name brand" ones costing 100s of $$$. Much
better to get a couple of the small, bookshelf "powered
monitors" peddeled to the home recording studio crowd.

So THAT'S how Bill Gates did it! :-]

Also... no wonder I have been having trouble keeping up on the TV
shows I watch when I watch them through my PC!

Or... Passes right through tin foil hats and all other blocking

By the size of it 20,000 decimilliwatts would be closer. Hmmm, I can
see it now, 2,000,000 M(icro)WATTS of PURE POWER!!!! Hope I'm not
giving ideas to anyone in marketing.

On another tack, what do you get adding up 1E12 microphones?

A phone.

1E12 phones = 1 megaphone

Uhmmm?

1E-6 is micro, and 1E6 is mega

1E-12 is pico, and 1E12 is giga

I think you figured out the joke, but messed
up with the scaling.

1E12 x 1E-6 phones = 1E6 phones = 1 megaphone

With 1E12*5 phones, one gets a worldwide phone system.

My computer speakers have 18" subwoofers. Well they are big sansui speakers
:) I run my sound card line out to my stereo. Forget them little junk ones.
