View Full Version : [PC Speakers] Even seen a parallel port used to connect speaker toamp?

This is so damn weird that I just had to ask if anyone else has seen
this before. I was just looking at the user manual for a 5.1 PC speaker
system that I was thinking about bidding on, and I noticed that while 4
of the speakers connect to the amp with typical audio plugs, the
right-front speaker connects to the amp with a damn parallel plug!

Why the hell would anyone ever do such a thing?

If you look closer at the manual, you will see that the right front speaker
has the controls for fader, master volume, and on-off.

Still, my standard advice re: Insignia brand: avoid if possible.

The worst sort of Chinese junk.

Ah, I missed that.

I've never owned an Insignia product before. The speakers did look a bit puny,
but I was mainly interested in the 5.1 amp.

That's not a parallel plug (DB 25), it is a 9 pin plug (AKA DB-9) of a
standard variety that has been used for any number of different things over
the past several decades. The basic design dates back at least as far as
the Korean war if memory serves. It used to be used on only highly
expensive, highest tech equipment but it has long been commoditized so it is
now used on even very inexpensive, low tech equipment.

In the realm of PCs, historical applications for exactly this plug (DB-9)
have included serial communcations ports and EGA monitor ports.

The tooling for making and installing this plug has been bought and paid off
for a long time so it is inexpensive to tool and produce. The patents ran
out decades ago. There are probably one or more production facilities for
installing it in production quantities in most major cities in the world
because it is so widely accepted.

The DB family of connectors has a good reputation for durability when used
with reasonable care. It is designed for, and well known to be effective at
handling a wide range of voltage and power levels that includes this
specific application.

Why do such a thing? Why not?

If a designer has a 9 wire analog interface, why not use a well-known,
widely available realtively inexpensive connector that has a reasonably good
reputation for reliability?

It makes replacing that speaker inconvenient.

Yeah, impossible; it's not like I could actually cut a hole in the
speaker box, run the speaker wires to another speaker, and effectively
"replace" the old speaker, while still using it's build in controls.

Like I said, inconvenient.

So a serial cable with 2 screws is "easier"? Easier than what? The other
speaker plugs that simply push in?

You're sounding a bit trollish, dude.

Those regulars who actually know of Dick will find that comment as amusing
as I do I'm sure :-)
As Dick correctly states, the connector is the least of your worries,
although his use of the term "impossible" is obviously not true. Since these
speakers are likely to be total crap, simply replacing any drive unit with
anything that fits, and leaving all the unique features alone, will probably
not degrade their performance at all, and should be easy enough for anyone
who can use a screwdriver and soldering iron. And the use of a common DB9
connector will be of NO concern for anyone who can!

No, replacing the old "puny" speaker (as I have previously referenced it) with
the same puny speaker is not an option. Therefore, the options are to
replace the speaker, or to not replace the speaker.

I did not buy them, nor did I ever place a bid on them,
since I read the manual first, and realized that
this was a product that I did not want.

I looked like a serial plug from the picture, but I specifically
referred to it as a "parallel" since that's exactly what the manual
calls it.

As for how common it's use is, that *was* the very nature of my OP.


Condisering how needlessly hateful you're being, you're obviously a troll,
so I'm not going to bother reading the rest of your hollow post.

*plonk*

So where's the problem? Just replace the crappy amp as well, and you're
done!
Or don't replace anything.

So *you're* post was pointless then, perhaps even a troll?

Dick will be sooo heartbroken! :-) :-)

I had no reason the believe that the amp was crappy.
My original idea was to simply get the amp and use it with my existing
speakers, as my current amp only has a 4 channel output, and the 5
channels of the Insignia amp would have been nice if I could have
grabbed it for cheap.

The point of my original post was to ask a question.
