Yesterday I paid a visit to a local hi-fi store. They sell mostly gear
of the crazy variety, but they also have excellent speakers, some of
which I wanted to listen to.
There I found a floorstanding speaker cut in half, lengthwise. The point
obviously to show the advanced technology used by this brand. This
speaker is manufactured by a well known expensive brand. I'm not sure of
the exact price of this particular model, it's a few years old, but the
latest version of it costs about $25,000.
Now to the point of this post. I could see the circuit boards of the
passive filters both from above and below. From above they looked just
fine, expensive components in a well-ordered fashion. But from below
they were horrifying.
They were obviously hand-soldered, which might be a edge in marketing.
But I'd say that 80% of the solder joints were poorly made. I've done a
lot of soldering. Many years. I have not made such a sloppy job since I
was 14 or maybe even 13. There were three categories; too much solder
(large spherical blobs), too little solder (almost none), even joints
with deep holes. All were shiny, though. So they were probably ok. But
wave soldering or skilled personnel would have made them almost perfect,
it's really not that difficult.
A speaker is prone to vibration (cough). It also has high currents
running through it. A bad joint might affect the sound, even stop it
completely. A bad joint might even get hot enough to start a fire. I've
never heard of that, but still.
This particular brand has a 10 year warranty, so obviously this isn't a
problem for them.
Anyway, I'm baffled. (Pun intended.)
Best Regards,
Gandhi
