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.
you can say that again. what year is on your sales slip? if it is from 1976 you should have the lifetime warranty. you just have to lie and say you bought them. I was looking at the catalogs that was the only year they offered the lifetime warranty. I am guessing if the old capasitors are old and shot they should be covered by that warranty.

Thanks for the canuck-connection there Brett!

I think that I need to wait a little while for some spare cash before I get the caps (wife and I just bought your first house...), really looking forward to then.....

Yup you may find when you open em up the foil from what used to be the caps popped out and unraveled . This usually caused by someone driving the amp into severe clipping. I would use some thing a little better than the Solens here (my opinion only). The other common cause of no mid\tweeters in R.S. speakers was oxidized L-pads take some fine sand paper and cleanup the windings and you may get your sound back.

Couple questions for you there amp-guy, what are the better caps (for a reasonable price) and which ones would speaker/horn be more beneficial to replace?

Iam not sure I want to get into that "what cap is best" discussion here, it's just that most seem to agree that the solens are kind of a bottom end of audiophile caps. for a step up the clarity cap 's are not very much more in price, again you will get as many opinions as there are people. As allways Buy the best you can afford.

As far as what order?, I would do the horn crossover first you will hear the biggest improvment here. Ill have to admit here that it has been so long that I really don't remember much about the Mach1 crossover, it seems like it was 12db/octave (anybody have one open to look?)

Nice read! Mine has the brown spray painted bottom. I've attached a pic of the crossover. Three inductors, three caps and two resistors. Can anyone tell if this is this one of the cheap crossovers/speakers?

I do understand the fanaticism that surrounds capacitors, but I am new to the whole area, and learn by asking others and trying things myself. I always appreciate the input that I can get, even if someone else things that you're wrong/they are more right! I just see them as different options. What I do like reading about is when people identify what the potential sonic differences are between different brands/applications.

Another question - is there a good place to view how to clean an l-pad correctly? I've looked, but I admit that I am not very good at searching for things.....never find what I'm looking for.

Most any polypropylene cap is going to be a world apart from those 30 year old dried out electrolytics. For cleaning the L-pads I have had good results using Cramolin De-Oxit . What I usually do is remove the back cover by bending the little metal tabs back and then use a small piece of silicon carbide wet-n-dry sandpaper 400 or 600 grit with some of the de-oxit sprayed on it and then finish with a shot of the de-oxit followed by an application of Cramolin preserve-it . these cleaners Can be found at www.partsexpress.com at least I think they still carry them. cleaning or replacment of the l-pads is important even if they are not scrachy as oxidization of the contact point can form a diode causeing rectification of the signal making them sound spitty and gritty .
happy modding! it's all fun

I have a set of 40-4029 Mach Ones which I have enjoyed for awhile.I just got a set of Klipsch KG4's which I also enjoy.
Got to wondering if I could re wire the Mach Ones for woofer only?
Any thoughts on this?
Thanks
