Speaker Source

[Tom]

What is a good source for speakers? I have a 50mm 16 ohm 1.5W speaker
I need to replace. Didn't see anything at Radio Shack or Newark or
Allied or DigiKey or Mouser.

My friend that builds custom stereo speakers swears by:
http://www.parts-express.com
But most of these are large speakers.
There are a few smaller ones.

Thanks for the tip. I don't see anything small enough though.

By the way, the speaker is from an AT&T speaker phone. For some
reason, it opened. No conductivity through the coil.

Must have happened the last time my mother-in-law called. Just
joking.

Have you tried applying some flux and then heating the speaker terminals
with a soldering pencil?

The terminals and terminal connections are okay. My guess is the
problem is where the terminal wires connect to the magnet wire at the
cone surface. I may try some micro-surgery there.

I don't think 2" speakers count as 'good'.

Anywhere basically.

Like where? Can you name a couple places please.

Like where? Can you name a couple places please.

Looked at RS Components and Futurlec and found none. 16 ohms is
not a common impedance. You'd have a little more choice if you
settled for 32 ohms. And a lot more choice if you could make 8
ohms work.

Tried googling ? I don't live in the USA you see.

Yes, 16 ohms is hard to find. I think I'll have to settle for an 8
ohm model that DigiKey has. I'll stick an 8 ohm resistor in series
with it and hope for the best. There may be enough power available to
overcome the losses in the resistor.

Yes. That's the first thing I did. 16 ohms is tough to find.

Well, if ultimate efficiency isn't vital use an 8 ohm unit with an 8R2 series R.

50mm ? I've seen Headphones using 2" speakers !!

here's a weird option; a couple of years ago i got a pair of "flat
panel speakers" for like 99 cents at one of the job lot type stores;
which were of course just a pair of those little transistor radio
speakers like you describe in a pair of cheap flat plastic housings
and a cable. for 99 cents, can't be beat.

You think like me. That's close to what I'm doing right now until I
get a built in replacement.

Yea, pretty small. The magnet is almost as big as the speaker.

the bizarre part is that although they were, of course, fairly crummy,
if you sort of strapped them to your head with a large rubber band,
they made dynamite headphones with really excellent bass.
don't do this in public, though.
