Speakers with questionable "upgrades"... post your findings here.

Sum of Sam - EPI put the butyl surrounds on top of the gaskets on at least some of their woofers. I've had two unmolested pairs with that arrangement. The speakers worked fine, and it may be that something about the geometry of the surrounds, or the different stretchiness of the materials (hysteresis?) made sticking the surround on top a good idea. But it looks and feels terrible.

Was that your set up Zonk? Man, cant say i'd stack some L212's 3 deep.. How did they sound.

No; sorry, I should have explained: Some dude in Massachusetts did that; I just tried to buy one pair off him. He may be a member here, actually, but IMHO he’s assumed the risk of any lighthearted mockery. He did say they sounded great.
 
Is the tweeter held in by a combination of the wires keeping it from falling out the front, and the insulation keeping it from falling into the speaker?
If so, it may be an attempt to emulate the Roxanne speaker which isolated the tweeter from the vibrations of the baffle by hanging it on springs. Oddly enough, this makes sense to me - when a tweeter produces high frequencies, its not moving a whole lot, and though enclosures should be relatively inert, they do vibrate, and if the tweeter is being vibrated by the baffle at the same time the diaphragm or dome is vibrating, the amplitudes might be similar and even though the frequencies of vibration would differ, they would intermodulate.
So that horror may be an act of creative genius - perhaps the cloth damps the resonances of the bubble wrap surrounds - though it seems to me that Fulton(?) speakers were advertised as taking away the veil, whereas these put it on...

The best way to hold a tweeter in and isolate it from the baffle is definitely liquid nail, but it can get a little messy.

I once saw a pair of Magnepans that had the mylar removed and a single driver plopped into a hole cut in the middle. Obviously the grill cloth no longer fit. They were at a pawn shop - I wondered what the dealer was thinking even taking it in - who would buy it?

What were they? ARs? I've seen those clear poly woofers in the Parts Express catalog years ago.

I like the board with foam keeping the woofer from tilting forward and rattling when the speaker is used with no surround.
But what is with the two frames around the baffles - is it actually two cabinets with one (or both) turned around so we are seeing what was originally the back? In which case, what is going on in the front? Maybe there is a standard driver complement, and these are test models for the Snells with the rear ambience tweeter!
 
I can't even understand what I'm looking at?!?! This looks like one of those "count how many things are wrong" comics that were in those magazines at the dentist's office. Counting in this picture, I lost track at 10. These speakers are truly a wonder!

These are by far, the best looking and best sounding speaker mods ever.
