20yrs ago I got walkman speakers that didn't use batteries. THirty years ago
I ran several 8ohm speakers off my pocket sized cassette recorder without
additional power. Now I can't buy ready made walkman speakers without
batteries. I'm prepared to make my own (housing will stink) but why?

20 years ago I got Walkman speakers that didn't use batteries.

You mean they don't have their own amplification.

Thirty years ago I ran several 8-ohm speakers off my pocket-
sized cassette recorder without additional power. Now I can't
buy ready-made Walkman speakers without batteries. I'm
prepared to make my own (housing will stink) but why?

I have several pairs of these I got during promotions at office-supply
stores. They use highly-efficient drivers that can produce reasonable volume
from the minuscule output of a pocket Walkman or Discman (20mW to 50mW).

Such speakers can't play very loud or produce a lot of bass. This is almost
certainly the reason they're no longer made, and have been replaced by
amplified systems for iPods. I have no idea where you would find the
necessary drivers.

Some "powered (amplified) speakers" can also be used passively.
But, sound level is markedly lower.

The market has shifted to "iPod speakers" which expect higher
efficiency "earbud" reproducers *or* "amplified docks".

You can similarly complain that you can't buy blank Beta video tape or,
better yet, blank *8 track* media!

I thought of that, Phillips SBA 1602, No luck.
