Floorstanding loudspeakers — Acapella SPHÄRON EXCALIBUR

The SPHÄRON EXCALIBUR is an extraordinary flagship floorstanding loudspeaker from Acapella, a German manufacturer known for distinctive horn-loaded driver technology, built with an almost unprecedented scale and mass. The SPHÄRON EXCALIBUR represents Acapella's absolute pinnacle of horn-loudspeaker engineering ambition.

Key specs that matter

Rated response spans an exceptionally wide 15Hz to 40,000Hz within plus-or-minus 3dB. Impedance ranges from 6 to 8 ohms. At an almost unimaginable 240.0 x 166.0 x 166.0cm and 620kg, the SPHÄRON EXCALIBUR represents one of the most massive and ambitious loudspeaker projects commercially available anywhere, reflecting Acapella's absolute uncompromising engineering ambition.

Sound and use context

Expect unprecedented dynamic scale and bass authority reflecting the extraordinary 620kg mass and exceptionally wide 15Hz-40kHz bandwidth - this represents one of the most ambitious loudspeaker engineering statements available anywhere in the world.

Pairing

Given the extraordinary 620kg mass, professional installation and considerable structural floor assessment are essential prerequisites well before this speaker reaches a listening room.

Alternatives

Acapella's own HARLEKIN 2 sits at a considerably more moderate (though still substantial) scale, worth considering instead if the SPHÄRON EXCALIBUR's almost unprecedented ambition exceeds what any specific room could accommodate.
