Is the SVS SB17-Ultra R|Evolution sealed or ported?
Sealed around a 17" 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.
