Floorstanding loudspeakers — Acapella HYPERSPHERE

The HYPERSPHERE is a legendary flagship horn-loaded floorstanding loudspeaker from Acapella, a well-established German manufacturer known for uncompromising ion-tweeter and horn-loaded driver engineering, built with staggering mass and sensitivity. The HYPERSPHERE represents Acapella's most ambitious current statement in horn-loaded loudspeaker engineering.

Key specs that matter

Rated response spans an exceptionally wide 18Hz to 40,000Hz within plus-or-minus 3dB. Sensitivity is a staggering 103dB into a flexible 4-to-8-ohm impedance rating - an extraordinary figure among the highest efficiency figures available in any commercial loudspeaker, reflecting Acapella's celebrated horn-loaded driver heritage. The horn assemblies measure 270 x 170 x 130cm, with a staggering total system weight of 960kg.

Sound and use context

Expect the immediate, dynamically alive character Acapella's legendary horn-loaded and ion-tweeter driver technology is broadly celebrated for, with the staggering 103dB sensitivity meaning this speaker reaches satisfying volumes readily from even the most minimal amplifier power.

Pairing

The staggering 103dB sensitivity makes the HYPERSPHERE compatible with virtually any amplifier, including the most minimal single-ended triode designs.

Alternatives

Acapella's own Hyperion offers a somewhat more accessible flagship-tier alternative within the same broader horn-loaded catalogue.
