The UNI-SUB 30 employes two W 300 S - 8 Ohm on the push-pull principle. These are screwed back-to-back to the baffle and one woofer is assigned to each stereo channel. The results are worth listening to. The frequency graph shows the high level of efficiency and the almost ideal bandpass characteristics of this subwoofer. This is connected directly in parallel to the stereo speakers whose bass needs boosting. For this reason it is important that the impedance curve of the subwoofer does not too fall to too low levels as otherwise the booster might be overloaded. Nevertheless, one should be careful with low-impedance speakers and amplifiers without protective circuitry (very rare today) not to set the volume too high.

The tonality of this universal subwoofer can be described as precise and very dynamic and is particularly well suited to reproducing high output levels.

The high efficiency of the UNI-SUB 30 supports medium sized speakers in the bass and low bass range and this gives the music its live feel.
