Common questions

ANSWERED FROM THE DATA

Is the Power Sound Audio S21 Ipal-M sealed or ported?

Sealed around a 21" driver, per its stated enclosure type. Sealed subwoofers roll off gently and stay tight and controlled — a strong fit for music, mixed use, and rooms where room gain hands back the deepest octave (small rooms, apartments).

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