Visaton Speaker Kit - Nano Sub
Art. No. 5936
Visaton Nano Sub (Nano Sat MKII kit shown left and right are not included) - shown assembled with suggested cabinets, not supplied.
Characteristics and Sound Properties
This is the matching subwoofer for the NANO SAT MK II . Together with the NANA SUB, you get a speaker system that is totally living-room friendly consisting of tiny satellites and a compact subwoofer which, all-in-all, sounds like a far larger, uncompromising column speaker set-up.
The BR 25.50 bass reflex tube with its flow-optimised, curved trumpet vent, contributes to the good overall sound of the subwoofer. The subwoofer cannot be located due to its 18 dB filter and separation at 150 Hz. A high-pass system and reflex balance enable the two tiny, magnetically screen satellites to produce remarkably dynamic sound. They can, therefore, also be used as centre or surround speakers for Surround systems at home.
Extract from Hobby HiFi: "The NANO system demonstrated clearly in the HOBBY HiFi test chamber that it music is a thing to be enjoyed. The response was extremely lively. But there was not the slightest hint of overdone effects..." "Particularly impressive was the dynamism that the subwoofer satellite system is evidently capable of. Anyone would agree that the bass unit has excellent level accuracy, but the satellites left us gasping for breath." "NANO is the solution where you want loudspeakers that are smaller than small." ... "However, you will not need to compromise sound quality: this speaker system can take its place at the top of the quality range."

Assembly
The boards for the subwoofer are glued (butt jointed) as shown in the drawing and subsequently the openings cut out. The fabric tensioning frame is fixed to the cabinet using wooden frame plugs.
The jumpers have to be removed from the twin terminals because one pair of connections is used for the right channel and the other pair for the left channel.
Internal Damping
The damping material is distributed uniformly inside the subwoofer cabinet but leaving the space behind the bass reflex tube free. A small amount is used for the Nano Sat MKII.
