Sigberg SBS.1 bump, Thorbjørn is developing a new version ( see his new SBS development thread) so this pair have to go.
Perfect condition, they must be used with a subwoofer I have been using them with one of Thorbjørn’s 12” Inkognito subs and they sound splendid.
Installation is plug and play, the speakers enjoy being close to the front wall and the inbuilt EQ takes care of any room gain.

SBS.1 and Inkognito 12” subwoofer, the Inkognito is a ‘pizza box’ design and it can ne placed vertically or horizontally.
The SBS.1 is a four way system coaxial mid/treble, dedicated mid-bass and then Inkognito subwoofer.

The SBS use Hypex NCore amps, which have built in PEQ, allowing you to have deep bass ( the SBS/Inkognito is a completely full range system) without any boom.

This is the story behind the Sigberg Audio SBS.1 active speakers, the design choices made and the reasoning behind them. Hopefully it is a good read to those interested in loudspeaker design in general and specifically the design choices made to come up with this somewhat unconventional design.

Thorbjørn that is incredibly generous.
The SBS.1 are superb, preconfigured to accept any of Sigberg’s subwoofers to create a completely full-range system.
They are capable of accepting either an analogue or digital signal, tomorrow the new Eversolo T8 arrives which has AES (amongst others) and the ability to attenuate volume!
Keith

 

[Purité Audio]

I have been experimenting using my SBS.1’s with the new Eversolo T8 digital transport, which can send and attenuate a digital signal, ideal for contemporary active speaker designs which accept an AES input.

Thorbjørn has designed a new ‘SBS’ and so my ex-demo pair which are in superb condition are looking for a new home.
Incredibly capable yet compact loudspeakers using the same coax mid/treble as the Sigberg Mantas.
Thorbjørn believes ( and I agree) that the main speaker shouldn’t be asked to produce bass so the SBS only extend to 80Hz thus the addition of a subwoofer is necessary.
Fortunately the adding a sub is no more than difficult than connecting and XLR as everything is pre-configured.
Astonishing hing drive, slam and completely full-range from a compact discreet system.
SBS.1 without grill,

Weekend Sigberg SBS1 bump, Thorbjørn is slightly revising the design hence the reason for sale.
They are astonishing loudspeakers, coupled with a subwoofer they offer a dynamic,completely full-range sound in a compact, discreet package.
Built in EQ allows you to enjoy muscular, tight bass without any ‘BOOM’!
