As Satie said, there are already foot mounting holes drilled through the panels, at either side of the panel near the bottom. You should be able to find them easily enough. If they're like the later ones, they have captive nuts and you just screw bolts through into the nuts. Here's an illustration from my IVA manual, this view is from the back of the speaker.
Anyway, I don't know how much metalworking/woodwork you can do but if you measure the distance between the holes you can probably find a corner brace at the hardware store with the right hole spacing. Then make some horizontal wood pieces for feet and screw the corner brace into the wood, using washers to shim as necessary.
You could also give Magnepan a call, and see how much it would cost to buy new feet . . .
Follow Ups:
IIRC my Tympani 1Cs used two 'L' shaped brackets (of shiny stainless steel), one was affixed to the front of a panel, the other its rear. Then the supplied screws were pushed through the holes in the brackets and the pre-drilled holes in the panels. Tightening the screws was accomplished on the rear of a panel, using the also supplied washers and nuts. Looking at the speakers it wouldn't have been aesthetically pleasing to see the tips of screws, washers and nuts on the front of a panel. Being only able to see the head of a screw was a better choice.
Being ~30 years ago I might well be misrembering, however common to many of my years I can more easily recall what happened 30 years ago than what I ate for dinner last night, (although I can). When I can't recall my name or the route I use to drive back home, I'll be finished. (In ten days I'll be 'celebrating', if that's what I'll be able to call it, my 80th birthday. Certainly no 'golden ears' here).
Happy Birthday Norman !!!
Thank you very much.
A big preemptive happy B-Day Norman , anyone who has seen first gen toobs in the flesh and todays current version , gets my vote ... :)
Regards
I (also) thank you very much!
Hey, happy birthday! And far better to celebrate it than not, we won't all make it that far . . .
Fret not, I felt the same way as a youngster after learning about someone having reached my age. But look at me now! :-(
I'm definitely fretting, I played some test tones yesterday and my ears now roll off at around 11.5 kHz! Last I checked a few years ago they still got up to about 15k. (Curiously, I can still detect some sound at various frequencies up to 19 kHz but the level is so attenuated it doesn't make a practical difference, down near the threshold of audibility.) Give me a few more years, and I'll be happy with AM radio . . .
Losing some hearing, and perhaps some hair and teeth (or even some bodily functions), 'goes with the territory', and isn't a biggie. It's when an older person loses their mind, that's a problem.
Teeth and hair, I've lost aplenty. At least my hair hasn't turned grey yet! And the teeth are getting replaced by implants that could buy a year's production of 20.7's.
As to mind, what were we talking about again?
Re implants; been there...done that, however only 2 so far, setting me back only enough for 3.7i's. However lots of other work including crowns, a root canal, extractions (and then their 'flippers'). Nevertheless, the DDS I visit biannually had expressed some surprise, and paraphrasing; 'man you got a lot of teeth ...for someone your age I mean, I bet you can eat anything', perhaps I'm looking forward to the day when I can't). Oh well, our medical problems are OT and uninteresting (to others).
Earlier Tympanis had a different foot, http://www.integracoustics.com/MUG/MUG/pix/mitchell/index.html
These is what the legs for many of the Tympanis looked like:
(The 1Cs, 1Ds and IIIAs and IIIBs had them)

Sorry (too much of in a rush), make that what the 'feet' looked like!

I think I am going to order the feet for the 1.6 for the middle panels and modify as necessary. Happy Birthday Norm by the way and I hope you see many more. I have been in touch with Magnepan and Sheila in the parts department has gone above and beyond. Thanks again everyone.
Petri 2830, I thank you.
"Earlier Tympanis had a different foot, http://www.integracoustics.com/MUG/MUG/pix/mitchell/index.html"
Those speakers in the picture, including what can be seen on their bottoms, are barefoot. Those tiny circular gidgets on their bottoms were never intended as 'feet'! If used as feet, they'd have been very unstable and a tiny fart might have turned them over. Just imagine, suppose you set them up, extended completely open and all the panels in a single plane. Feet were comprised of a pair of 'L' shaped brackets secured to the front and rear of a panel by screws, washers and bolts. The vertical part of the 'L', being where brackets contacted a panel, and the horizontal portion comprised feet, making contact with the floor. I attached/separated my Tympani 1C feet several times; standing them up to begin with (I can't recall the particulars, but my dealer didn't do it), then taking them down and putting them back up again after having shipped them to Magnepan to completely refurbish (repairing the damage done by the UV sensitive adhesive, they were returned to me looking like new), and then down after having sold them.
Ah yes, it's been something like 20 years since I disassembled my 1-D's and I'd forgotten that the feet were in two parts. (A friend had them on loan after that, since I didn't have a large enough listening room to set them up.)
The old feet look awful!
Having them on the front was handy for kicking your Tympanis into place, though. :-)
