Interesting solution . Maybe you need something like two powerfull zeners in opposite direction in series ,or varistor , parallel to tweeter itself , and run tweeter through incadescent lamp .But question is resistance of tweeter ,max operating current , lamp resistance when cold and so on . Maybe experts can recommend something practical or more concrete value to choose .Small voltage and power incadescent lamps are still available to purchase .
If you think hanging speakers is a good plan, at least consider adding a winch. That's how the big arena sound systems are hung. Even a $29 hand-crank boat winch to a pulley.
Yes, I've been considering that. Used to have one, that I used to crank up my 3 tube Electrohome CRT projector in place. That was 3 homes ago and I've lost track of it.
I'm also considering the capacity of the beam itself. Construction is one vertical 2X4, two going off at an angle, two perpindicular - which are the ones I'm hanging speakers from. They're all joined at the center with a fastener that looks like a rectangular steel plate, that has been stamped leaving an array of tines sticking out one side. This is then bashed into place during construction with a hammer... One on each side of the 5-way joint.
The HLS 610 is a speaker I can hold in one hand. I also have an HLS 615 pair and a set of TABAQs I built which are bigger and heavier. At some load, the 2X4 beam will come ripping out of its cheesy plate fastener. I dare not reinforce it, with a few "confidence bolts" - then find 10 years later some inspector tells me that structure section needs to be rebuilt before we can sell. I know my luck in such matters.
I had the speakers on shelves up against the back wall, where they sounded like crap, compared to the "hanging in space" arrangement.
I would figure a "point load" is a carpenter or roofer standing at any arbitrary point on the structure. If your speaker is lighter than a guy with a hammer and bag of nails, and you don't support yourself on the same point (say, use a ladder instead), I would not try to retro-engineer those rickety trusses but just assume they will hold.
First get a good pulley next to the speaker location. Sadly good pulleys are hard to find. You have access to marine hardware 20 miles away but we can't afford those prices. I haunt yardsales and eBay for pulleys. Another piece is Tractor Supply Snatch Block. (Sounds like a rude item but with a bit of chain will lift a Jeep.)
Bolt winch to wall-stud chest-high. Rig winch-line over pulley to speaker. Take a strain. Detach speaker and let it down slow. I'm losing my dance-moves too and I would prefer scaffolding even though there's never more than 10 pounds in hand up high. But note that my only scaffold is a 15" painter's platform......
Obviously you don't leave stuff hanging on a winch. Get it up there and hook it or chain it or screw it, something that WON'T get loose, ever.
