The Phantom Ultimate CI 98 dB is a fully active bookshelf loudspeaker from Devialet, a custom-installation variant sharing the Phantom Ultimate 98 dB's internal amplification specification. The Phantom Ultimate CI 98 dB brings Devialet's considered engineering to a custom-installation-oriented active loudspeaker format.

Key specs that matter

Rated response spans an exceptionally deep 18Hz to 25,000Hz within plus-or-minus 3dB, matching the standard Phantom Ultimate 98 dB. Internal amplification delivers 400W, also matching. The CI designation suggests a specific custom-installation cosmetic or mounting treatment differentiating it from the standard retail Phantom Ultimate 98 dB.

Sound and use context

Expect surprising bass extension and dynamic scale reflecting the exceptional 18Hz reach combined with the substantial 400W amplification, matching the standard Phantom Ultimate 98 dB's engineering within this custom-installation-oriented variant.

Pairing

As a fully active design, the Phantom Ultimate CI 98 dB requires no external power amplifier, connecting directly to a source component or preamplifier with line-level or wireless streaming input.

Alternatives
