Common questions

ANSWERED FROM THE DATA

Is the PSB Alpha S8 sealed or ported?

Ported around a 8" driver, per its stated enclosure type. A ported design uses a tuned vent to play deeper and louder from the same amplifier — what movie soundtracks reward — at the cost of a steeper drop below the port's tuning frequency.

Computed from this product’s normalized, source-tracked fields — an unstated spec reads as “can’t check”, never as a yes or a no.
