腳釘會壓壞磁磚。
一些 JBL 大型喇叭說明書裏都有寫。
Everest DD67000 一個就 142 公斤了。
這個 S9900 才 82 公斤,說明書就提及腳釘壓壞磁磚。
The system is ported on the rear with a tuning frequency of 35Hz. A large
4-inch (100mm)-diameter flared port is combined with the input connections
on a massive die-cast aluminum structure. The entire enclosure rests on four
stainless-steel foot assemblies. Stainless-steel coasters are included to protect
wood and tile floors from damage from the spike feet. The grille assembly is
constructed of fiberglass-reinforced ABS to provide the curved shape. The
grille is securely attached to the enclosure with metal pins and rubber cups.
