Speakers have been a great weakness of mine ever since the weekend I 
came home from school at around age 7, and discovered that my brother 
had put several salvaged television speakers in the corners of our 
shared bedroom, and one under each of our beds, then tied the whole 
pile to our AM radio. Despite the phasing and matching issues that 
neither of us had ever heard of at the time, that conglomeration 
impressed all the kids in the neighborhood. It also caused a run on 
discarded speakers of any description, and on rolls of single strand 
"door bell" wire at our local Western Auto store.

All that to say that my speaker of choice for my TS570S is an oval 
shaped speaker that is approximately 3 by 7 inches. I bought it from a 
local guy at a hamfest in 1980 for a whole fifty cents. That price 
included a very dirty metal cabinet, which housed the speaker, along 
with several switches and test pin type connectors. The fellow told me 
it came in a bunch of surplus stuff he had gotten in a trade. I 
removed the other components out of the cabinet, cleaned it up, and 
added four rubber feet.

I have a Kenwood SP120, which is basically the same speaker that is in 
any of the Kenwood external speaker boxes, but the sound isn't worth 
the price one pays just to get a matching cabinet that looks pretty.

I have two of the Motorola speakers that Tom described. He is right 
about those speakers not being very easy on the ears for SSB. After 
all, they were built to project narrow band FM audio in a noisy mobile 
environment.

A local friend uses the MFJ speaker that Tom mentioned with his TS480. 
I have not heard it, but he says he likes it. I forget the model 
number, but MFJ sells it for about $40.

The short summary of this ramble is, try cheap yard sale or hamfest 
bargain speakers first. If they sound good or terrible, you will know 
immediately, and will either be very pleased, or only a little 
disappointed without breaking the bank in the process.
