I like the idea of hooking a guitar amp up to a transistor radio speaker to
see how far the magnet flies.

All the more reason to encourage them to learn to make and fix stuff.

Price is never an indication of quality - it's just an indication of what
other people are willing to pay - which - marketing knows - is highly
influenced by marketing garbage.

So, a 6x9" 20W $5 Parts Express speaker might or might not be as good as a
6x9" 20W $300 speaker at Toyota which itself might or might not be as good
as a 6x9" 20W $25 speaker at Crutchfields.

How are we to know?
Sure, in the days of yore, we pored over those 3db power:frequency curves,
from 7KHz to 20KHz on each speaker box, and where, folks like Jeff
Liebermann would know, they always find a way to lie a little bit.

While I doubt the $300 per speaker at Toyota is a fair price, how can I
tell, a priori, if the $5 speaker at Parts Express will be as good (or bad)
as the $25 speaker at Crutchfields?

Is there any way for a consumer to make an intelligent speaker decision?

A good indicator of quality is magnet mass. If it has a tiny little
piddler of a magnet it will not handle any power - particularly bass.
Then lookat the cone material, and the surround. The spider is also
important- The basket is less critical - but in a large powerfull
speaker the basket will be MUCH solider than on a cheap-ass speaker.
If youfind a speaker with a cast aluminum basket you know you are
looking at a higher quality speaker - and if it is stamped steel, the
heavier the better.

Poor suspension spiders and surrounds will let the voice-coil scuff
on the magnet core - which makes a speaker rattle. A flexible basket
can do the same. The surround compliance is different on a speaker
designed for an accoustic suspension box than for a bass reflex, or an
open baffle like in the average auto rear deck. Toyota actually used
accoustic suspension on some of the "premium" sound systems years ago.

LOTS of things you can look at.

I have a pair of OEM Toyota speakers from the eighties sitting here,
as well as a pair of speakers from a Zenith TV of about the same
period - virtually the same size - and the Toyota speaker is
significantly heavier. Thicker cone, thicker basket metal, and more
rigid design - as well as a MUCH larger and stronger magnet, The
Zenith also uses an "m"formed paper surround, while the Toyota uses a
rubber surround. I've got a "tin ear" but even I can tell the
difference between the two.

The drivers in my AudioResearch towers are MUCH heavier than my
no-name set too - and I replaced the foam surrounds that had totally
"disolved" from age with new high-quality synthetic rubber surrounds -
on both the active and passive 14 inch cones.

In automotive speakers the basket rigidity is more important because
of the "G" forces experienced when driving on rough roads. The cheap
speaker might sound good when installed - but it may be pretty auful
two years later.

Wait a second. The kid next door you're doing all this for is a girl.

That's pitiful.

Two stories. Before cellphones: A girl I met at a lecture -- not
attractive and I wasn't interested in her -- calls me on a Friday or
Saturday to change her tire. I say, Can it wait until Sunday. Yes.
I'm there, doing it and she's not watching. I say, Why don't you watch
so you can do it yourself next time. "I'll call someone" "What if you're
out in the country?" "I never go there". I finished the job and left
and I hope she thought that was why I never called her. If she'd been
cute, I still can't imagine spending my life with someone like that.

(Plus she didn't seem very appreciative to let me work while she
wasn't keeping me company, at least)


Shopping for a car a couple months ago, guy had a beaufitul red Mustang,
special black trim, special power chip for ignition, car 12 years old
but interior (leather), exterior, engine compartment like new. etc.
Stick shift. One of his teenage sons was sort of trying to learn to
drive it and the other wsn't even learning to drive! The normal thing
to do woudl be to give the car to his son, but neither could handle it.

They're all dreadful. It doesn't matter which one you buy, it will be
dreadful. So buy the cheapest one or the most convenient one and don't
worry about it.

No, because it's basically not possible to get decent sound in a car anyway.
And even if it were, it wouldn't be possible to do it with the typical
full-range whizzer-cone speakers that we're talking about. So buy the cheapest
ones you can get and it won't sound any worse than it did when the car was
new.

Times have changed. When we were in our early teens we were driving
with dad in the parking lot and could not wait until we were 16. My
brother turned 16 on a Thursday and passed his test on Saturday. I was
about 2 weeks after my birthday taking mine.

Now, having the latest cell phone is more important than cars and
driving. Stick shift? Nah, they can't do it.

I'm SO lucky that my hearing range is limited -- the 1988 POS Caddy
speakers were just fine, as are the 2016 Corolla speakers.

Hubby used to be able to hear earthquakes a few seconds before we could
feel them, though. Maybe he still can, we just haven't had one worth
noticing for a while.
