Characteristics and sound properties

The NANO SUB PR is a smaller alternative to the original NANO SUB. The capacity of the cabinet has been reduced to 20 l. In order to achieve the required low tuning frequency with such a small cabinet, the bass reflex tube will either have to be extremely long or have a very small cross-section. Both will lead to considerable airflow losses. So instead of using a bass reflex tube, we use a PR 250 radiator. This enables us to design a far more compact subwoofer and, at the same time, compromise as little low-frequency bass as possible.
The tuning frequency can be adjusted on the PR 250 by means of the additional mass. Without the additional mass, 36 Hz is possible and with the enclosed nut and bolt, 30 Hz. Of course, since every room has its own acoustic properties, you should select the option that provides the best actual listening pleasure.
Apart from being used in the passive NANO SUB/SAT system, the NANO SUB PR can, of course, also be used in an active system, e.g. in conjunction with a Thommessen Proteus SW 0.8 amplifier. In this case, the GF 200 2 x 4 Ohm voice coils are connected in series while the passive crossover and terminal connections are no longer needed.
Not longer available.
