re: the surrounds, I think (based on some internet research) that there might be three different iterations. 1 is the rubber surround (model 40-4024), the foam (40-4029) and a hybrid (?) foam that holds up very well (40-4024a)

re: the caps - Is it worth while getting better quality caps? I`m not sure if I have the extra cash-ola to spend on something more than the Solen fast caps I was looking at...

Also, I live in Canada. Is there a good place to get good cap's up here? The only site that I know of that has decent stuff is solen.ca.

The Solen caps will do great and they are cheap enough.

I have some mach three's and will never part with them. Had them in my dorms and it shook 7 rooms down. A surround is gone on one of them now. Gotta replace it but too many other projects get in the way!

I do have to say that I really enjoy the sound of these speakers, maybe it is just the sound of a horn, nice, rich full sound, albeit a little weaker on the bass than I would have thought it to be....maybe I need some more watts into them, although there are 60 watts of Sansui power feeding them....probably equivalent to 100 or more of todays watts.....

I just wish I could find another pair of them cheap. I don't want to pay the eBay prices. In my own opinion they sound better then a lot of speakers. they are great party speakers. you can make your house sound like the night club. Big bass, nice mids and nice highs, and they used a real crossover unlike a lot of other speakers. a lot of people think radio shack = junk. but back in the 70's threw the early 90's they made great sounding speakers as long as you bought the top of the line. around mid 90's their speakers started to go to H___. I flipped a pair of realistic optimus T200 tower speakers radio shack came out with in the late 70's. they had dual 10" woofers rated at 16 ohm each. ran in parallel. they cost more then the mach ones when new. there is a web page to look up old radio shack catalogs. http://www.radioshackcatalogs.com/ if you look at the catalogs you can see how the speakers started to go down hill. it started to get worse in 1994. in the early 90's they stared the mach 3 speakers only in 1992 and 1993. they are very rare to find. they are based off the mach one with the horn tweeter and horn midrange. you really don't see these coming up for sale. they didn't make them long. they made the mach two for many years and they made the mach one speakers for many years. they came out with a pro 4000 speaker in 1994 removing the tone control knobs and getting rid of the oil rubbed finish on the high end speakers. they made them cheaper to save money. if you look at the catalogs from them on the speakers kept getting smaller and smaller.

here is some more info the mach one speakers went for 20 to 25,000 Hz, the mach two speakers went from 25 to 40,000 Hz, and the mach three speakers wen from 30-20,000 Hz. the mach two speakers had the highest range of sound but if i remember right we cant hear what it goes up too.

the mach one speakers had the deepest bass but the mach twos had the best freq responce.

oh i forgot to say the mach ones came out new in 1976 and had a lifetime warranty. cat number 40-4024 and it's on page 46 http://www.radioshackcatalogs.com/catalogs/1976_small/ I wounder if you had the sales slips if they would still owner the warranty. In 1977 they came out with the 5 year warranty. i guess they changed their mind about offering a lifetime warranty.

The Solens will be fine as will the Mundorfs I mentioned which are similar price, at PCx anyway. You don't need to spend any more than these cost.

Have you never heard of Parts Connexion? Also in Canuckistan

Bit of a memory lane trip with the catalogues. The Aussie ones were a bit different, but similar. I remember wanting a set when I was in high school and not being able to swing the $A299/spkr they sold for for years. Got my set about 2 years ago, and they came with the purchase receipt and a single line sales brochure on them.

They are quite good speakers. Not just for partying; I've been using mine as mains in the HT for a while, whilst I slowly build the new speakers. They do some stuff wrong, but they are fun to listen to.

Man did you just bring back some memories. around 1976 I was starting college and took a job as a tech at a regional repair shop at Radio Shack where I worked till about 1980. The Mach one speaker was pretty tough it took some pretty serious abuse to do damage . The T100 T200 was my favorite they delivered some pretty respectable sound . I actually have a few mach one woofers that I purchased as replacement parts back then which I have used in powered subs. so if you find some with bad horns don't overlook them for that use. Replacement surrounds are readily available and are quite simple to replace.

I sold the pair of T200's that I had on ebay last year for 200 dollars for the pair. they are quite rare to find. they were listed for some time before they sold. they were almost spotless but the one speaker had a ring stain in the walnut vineer. most likely could of been cleaned off with howards restore a finish. but it didn't look that bad.

I wouldn't pass them up with bad horns. if the cabnits are good you always see stupid people parting them out on eBay. mach ones go for less money being parted out on ebay. they would be better off to ether ship out the full speakers or sell them localy and do a buy it now price in their ebay stores and not worry about a quick sale. it took me about 2 weeks before my T200's sold I wasn't even sure what to ask for them so i did a buy it now price at 300 or best offer. I am guessing if the economy was better they may of sold for the 300. I couldn't find another pair that sold to get an idea of what to ask.

I bought them to flip since I have other speakers I like. They sounded so good I wasn't sure if i wanted to keep them and sell what I have or sell them. To tell the truth I wish i would of sold the infinity sm-152 speakers and kept the T200's
