Does Magico use anything like polyfill or foam inside their speakers?

Hi Folsom. If they didn't, I would be very surprised.....although I can not answer your question with complete 100% certainty. 95% certainty perhaps.

They need for it goes down the less efficient a speaker is, and there's are not high efficiency, so it's plausible to not use anything without incurring huge problems. But still, I figured surely they would... I just don't know.
i think so, at least in some areas. fyi ... my yg's have foam in some areas. if you remove the mid woofer it looks like an erector set inside the cabinet with giant caps and foam in a couple areas. the foam is in between the mid and tweeter cabinet areas.
no, but they have something that looks like dynamat lining the cabinets inside from photos online.
Depends on the design and personal preference as far as how much and what kind. IMO it's better to have it a little overdamped than too resonant, but my Pioneer S-1EX are pretty well-stuffed and I think the bass is a little overdamped. The amp makes a pretty big difference too, as it's DF has a similar subjective effect vs stuffing a speaker, so the speaker designer needs to think about what amps will be used with the speaker. Lining the walls with dynamat-type material, foam materials or a combination is doing something different vs stuffing, I forget the exact technical terms, but it does have a different effect so you might find a combination of the two works best. I do agree that lining the walls of a cab to reduce wall vibration is a good idea unless you're going for the cab adding it's own tone.
I think polyfill generally just make it sound bad in all the octaves but the lowest it seems. It might compensate for something else, but it isn't the right answer.
To me I see no limit in dampening the walls. And to a large extent using certain types of foam and things on them to reduce reflections. You need pressure, not reflections, inside a cab.

For me it's useful for tuning the woofer...
Damping the walls needs balance too though, if you add mass without stiffness you lower the first resonant frequency of the cab. If you're starting with something very stiff like aluminum though it might not be an issue. I'd guess magico uses a layer that forms a cld like dynamat on a car door but idk... Aluminum is a bit over the top for a speaker cab imo.

I think aluminum is a great cabinet these days, after what I've heard. But I suspect Magico's primary use for their dampening is to stop any potential ringing.
Just a correction: YG uses no filler/stuffing material, as they have their own resonance-damping technology.

Graphs without labeled axis make me angry!
There is no way to follow or understand wtf they are claiming with that info. Engineers need to have some say in the marketing materials, lol... My conclusion is the cabinets are actually passive amplification devices, not sure how this could be a good thing as it would have to be due to resonance.
incorrect. at least in the carmel versions. looks like the same stuff as above in the magico's (not the furry crap).
