It never fails to astound me how much money hams spend on "matching"
speakers for a piece of equipment. It amazes me even more when the money
spent produces such crappy results!
Of all the "matching" speakers I have played with, I have only found two
that actually worked right.
Hammarlund has two good ones, the 200 and the slightly smaller 100. Both
work very well on CW, SSB and AM. The response is tapered so that excessive
boomy bass is rolled off gradually and the highs are not too shrieky. This
produces clear copy with lightning static and some heterodynes reduced in
level without damaging intelligibility in speech. You can use a hi fi
speaker for the class E rigs on AM under good conditions. But you cannot
beat these for general use performance. The Hammarlund accessory speakers
are also very sensitive and produce a lot of output from even the wimpy
output stages of modern solid state receivers.
The Heathkit SB-102 and SB-104 speakers are also winners for similar
reasons to the Hammarlund models.
You can get a nice speaker for speech and CW from your thrift store that
works better than the over priced crap. I include a photo of a pair that I
bought for $10. The power level specified is low. That means they gotta do
loud with a wimpy amplifier for a cheap stereo. It also probably means they
do not have the boomy ultra lows. And there is probably not any
excruciating highs to enhance the heterodynes and static crashes.
When you get old and your ears start to crap out, you need a good set of
speakers for good copy off the radio.

But like the song (sort of) says:
"Why waste your money on a new pair of sneakers,
You get more mileage from a cheap set of speakers.
Matched phase, half wave, tubes blaze, anyway
It's still radio to me...."
