If you take @dweller's advice, use 19mm 13-ply Baltic Birch plywood, the stiffest wood (we're all adults here, right? ;-) available. But the Sound Anchor stands ARE really good; I too have a pair.
Any steel 14” to 16” speaker stands out there?
I am looking for a pair of quality stands for my new toys, jbl 4429’s. I have them on some cheap wooden 12” stands currently but they need to come up about 4” and get on a solid stand. The jbl stands are only 8” tall and angled up. Rather try a 16”er but can’t find one... I should have kept my old Spendor se100 stands! Any thoughts? The jbl’s weigh 62 lbs. each.
