PC Speaker System Question

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.

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.

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.

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.

- YD.

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

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.

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 devices!

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?

- YD.

A phone.

Uhmmm?

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

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

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

Bzzzzzt! I saw that other pun in the middle! :-)

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. JTT

Mine feeds one of these:

you mean ... u have one main unit in that it have 2 seperate external output...... If ur answer is s then u will connect the required speakers(specified power). After that if u does not hear any sound then it needs an audio amplifier.....
