SUB-28 Vari LineSUB-28 Vari Line was designed for use as a subwoofer in active multi-way systems.
It has an excellent transient response from classical bass-reflex but is also suitable for medium to
high bass fields. 700W RMS long subwoofers are equipped with extremely low THD,
which are very reliable. They also include Voice Coil Tracking Protection, which prevents
overload of 100 mm coils of "sandwich" voice. For maximum dynamics, SUB models driven by extremely powerful amplifiers can reduce the power by means of a thermal fuse virtually inaudibly to a "soft" power reduction.
