The SUB W-20.39 is the ideal subwoofer for boosting the bass output of smaller or medium-sized speakers. On the one hand, it is powerful enough to generate driving low-range bass effects in normal rooms and, on the other hand, highly compact. In large rooms or if extremely high bass output is required for longer periods, a second subwoofer of the same type can be added.
If the SUB W-20.39 is to be used in the vicinity of a TV set, then instead of the W 200 S - 4 OHM, we recommend using the magnetically shielded W 200 SC - 4 OHM. This prevents the TV being distorted by the magnetic scatter field.
In addition, it is also possible to use the 8 ohm version of the woofer (W 200 S - 8 OHM, W 200 SC - 8 OHM) if the amplifier used does not allow lower impedance speakers to be connected or if several subwoofers are to be combined.
