You can find minimus-7's and 77's on eBay.

I did, they arrived, I hooked them up and after a couple of hours they
were just like my other 15-year old Minimus-7's - the foam surround
crumbled and fell off the driver.

Well, now I have 6 Minimus-7's, 5 with basically zero foam surround
left and one that's just on the verge of falling into pieces.

I gotta learn how to fix these foam surrounds! Either that or buy some
brand new drivers.

Look in your phone book for "speaker repair." The foam disintegrating
happens a lot in dry climates, and if the voice coils aren't too
abraded, they can be replaced by a speaker repair tech.

The voice coils get abraded by using the speaker as the foam is
disintegrating, and they wear against the surrounding magnet and
frame.

It's ozone. The surrounds go to Hell in Houston as well.

Of course in Houston they're two thirds of the way there already. : )

There are now DIY foam-surround replacement kits
available. Apparently easy enough to market to the
more competent of the general public.

I have a nice die-cast Radio Shack bookshelf speaker I bought probably
15 years ago that I use on my SW/Ham radios. It's not a perfect speaker

I think Radio Shack sold them as outdoor/patio type speakers when I
bought them and I seem to recall the name "Minimus-7".

I go to look at Radio Shack and they don't have anything like this
anymore. They've got some really crappy plastic-tinny sounding speakers
that I don't like at all, and would probably break the first time I
looked at it funny.

What speakers are available in durable die-cast housings these days?
And I hate tinny sound (like comes out of a PC-clone speaker). I
refuse (just out of abhorrence of the sound) to look at any PC or
PC-with-amplified-subwoofer crap speakers.

Did I mention that I don't want any PC speakers, and they all sound
awful? (Hint, hint, DO NOT SUGGEST THIS OPTION!)

Tim.

Buy a system like this at the thrift shop. Throw away the
electronics, keep the speakers.

Tim, you might also search for the name "Optimus" Same cast Al case and
speakers with internal crossover networks. Same speakers as the Minimus,
different timeframe. IMHO, neither sound near as good as a good set of
stereo phones, but agree that it's easier to demonstrate to visitors using
the speakers.

Why not check out the auto junkyards for some good quality speakers
(look for the most expensive junk cars in the junkyards) and mount them
in an appropiate size wood box cabinet?

Tim / TE,

Look on eBay for one of the Center Channel Speakers from a
Sound-A-Sound System that has a Wooden {Particle-Board}
Speaker Enclosure. These usually have a Pair of 4" to 5.25"
Mid-Range Speakers and a much smaller Tweeter placed
between them.

Here is an Example of a Center Channel Speakers Listed on eBay :
JBL EC25BE 2-Way Dual 5-Inch Center Channel Speaker
http://cgi.ebay.com/_W0QQitemZ5858432743
The NorthridgeTM E Series EC25BE center channel loudspeaker was
custom-designed to superbly reproduce the human voice. Many movie
soundtracks consist mainly of dialogue, so that the center speaker
shoulders the burden of filling a home theater.

"The 'SOUNDS SWEET' Communications speakers maximize intelligibility
from your transceiver, receiver or portable by reproducing only the
communications voice and shortwave music frequencies coming from your
SSB, AM or FM communication or shortwave radio."

A Little "Pricey" at $99.

Also, if you are using one of the 'portable' AM/FM Shortwave Radios.
Check-Out the Kiwa "Audio" Mods for a better sound from your radio.

FWIW - External Speakers for the ICOM IC-R75
http://groups.yahoo.com/group/icomr75/message/4360
Here are the Two Most Often Recommended External Speakers
for the Icom IC-R75; as suggested by the Members of ths eGroup.

#1. RCA Mini-Speaker Pro-X33AV
Radio Shack Cat #40-5000
http://groups.yahoo.com/group/icomr75/message/1312
A shielded 2-way speaker with a 3" woofer
and a dome tweeter about 6.5" high.

#2. RCA 20-Watt Full Range Mini-Speaker
Radio Shack Cat # 40-5024
http://groups.yahoo.com/group/icomr75/message/2031
http://groups.yahoo.com/group/icomr75/message/769
A shielded full range 4" speaker. It is a Black 5" cube.

NOTE: The general comment is that both of the above external
speakers in the "Black Color" looks very sharp next to the R-75.

OTHER - Speakers mentioned frequently that are good with the R75.
* Optimus PRO-X88AV's RadioShack Cat # 40-2084.
* Barjan PROnouncer (320-25) 4".
* Radio Shack XTS 25 (40-1999A)
* Radio Shack 21-549A isn't a 'full range' music speaker. It is
a 'communication/voice' speaker.
* Minimus 7 Speaker by RadioShack 4" Speaker
* KLH 911's (2-way semi-compact at about a foot tall)
* Mocom 70 4".
* Grove SP-200B sound enhancer

NOTE - Most 'matching' Speakers offered by OEM manufactures
are basic 3"-4" Speakers in a Sealed or Ported in Metal Enclosure
designed to opperate on a few Watts output. A simple Speaker in
a tin box for $60-$120. But Hey it 'matches the Receiver and has
the OEM's 'Brand Name' on it.

Go to Ebay and buy used Minimus speakers...

Search for minimus, radio shack, and RCA, the last brand on them..

I have a set of the RCA and two set's of RS Minimus, and the RCA and the
newer of the two Minimus are exactly the same, except for the RCA logo.
