does anyone know the port tuning for HLA 4897 sub?

Hello, the 4897 sub is tuned to 34Hz with around 478liters
they have a very smooth response between 30 and 120Hz like suggested.

for less demanding applications they can be crossed at 90Hz especially
if the subs are not too close to the tops 4895
