25cm Reference Series Subwoofer
This subwoofer is part of the Pioneer Reference Series.
Now featuring an inside magnet as opposed to an outside one, this woofer pounds freely in its case, offering 22% higher magnetic flux and even deeper bass.
The progressive dual damper takes care of an improved power/quality balance and a lower frequency (45 Hz).
A 3-layer voice coil (4 ohm), combined with the extremely light Aramid Fibre edge with rubber coating, results in high sensitivity and speed and an linear bass range.
