The SUB 20 is a very compact, passive subwoofer designed for use in multi-channel systems with a system controller. It produces remarkable bass levels thanks to a high-power 6.5“ long excursion driver in a double-vented bandpass cabinet.

Thanks to its slim design, compact dimensions and defined sound outlets, it can be easily concealed in furniture and fittings. The SUB 20 features two parallel-switched Speakon terminals (input and thru) or pluggable screw-type terminals. The connectors are recessed to ensure that plugs and cables can be hidden from sight.

The SUB 20 is the ideal match for satellite speakers in our installation series as well as for the ZL 50, ZL 100, ZL 104 and ZL 108 column speakers, and for the built-in speakers in the DE, DE-X and DE Plan series.
