Another Op-Shop find
I know they are not "Good" but they work and they were cheap.
Was $5- too much?
Add the small sealed box I paid $1- for an 8inch woofer and a couple of second hand components and these may do for small gatherings.
Realistic #2011Aa
I have seen small tweeters with bigger magnets, 8 inch paper cone pleated paper surround and complete with "L-pad"
 
have been able to find out nothing, except that thousands were sold; perhaps 10's of thousands even. Found a google link to some selling in the Phillipines for $USD 55- a pair but that is way too much.
Last month I found a pair of "Broken" speakers on the footpath, hashed up old repair job and blown tweeters of course.
BUT
8inch Dai-1chi woofer ( SP8-30 ) which has reasonable "Doof-Doof" capability, 30 litre box and the same width as the midrange enclosure
SO
Budget project is now in the pipeline , I have a couple of ferrite cored 5.8mH coils in the spares box. First on the woofer and second LR ( electrical of course ) on the little one??
Somewhere around 400 should offer reasonable protection for the mid where to put the first order XO on the woofer??

OK been well over a week now.
Is 8 years too long to report back?
I didn't reply because they sounded AWFUL in a very one note doofish way.
Also lots of breakup in the top end so also useless in a 2-Way.
Huge component sale at the thieves market when the shed gets cleaned out soon. I'll be asking $10- but I might have to pay somebody to take them away
