A thread on this topic could be an inspiration for newbees & interested folks
Here some ideas I realized:
glued in egg crates (the real ones) and using a thin sheet of damping. Thats for being localized more in the middle of the box where it is damping lower frequencies than only being positioned on the walls
reflex port in the corner of one wall as a cutout and port made of cardboard sheets glued in. Easy to realize bigger port diameters like this.
piezo tweeter on the side for indirect high frequency dispersion but it can be put on and off to taste

correct. lead is very good for damping resonant walls.
In germany its not allowed in commercially available loudspeakers.
Lambs wool I still have half a ton of it from isolating my house.
But would not use it for reflex boxes.

once I saw in the 90ies a french hifi shop owner using lead.
He made a mass loaded construction of a loudspeaker enclosure:
38 mm particle board and four layers of lead sheets glued with ceramic glue which got hard after finishing binding process.

Zinc is a possible substitute for lead sheet, but although its soft its not as soft as lead. Tin would be a great substitute but its a lot more expensive. Cutting mats are quite flexible and heavy, possible alternate material too?

a good choice would be Hawaphon from Korff, germany.
