Quick question.

I have bought a pair of MA CHR-70 drivers to drop into frugalhorn mk3 cabinets. This is my first non-multiway build. I understand that a vented pole is desirable in high xmax drivers to reduce pressure loading on the cone.

I’ve noticed that the CHR-70 has a vent, but it is effectively sealed by the sticker on the magnet. Should I cut the sticker and expose the vent, or is the driver best left unvented?

Thanks guys! Been cruising this forum for years and appreciate all information available at my finger tips!
