The Affordable Audiophile Collection

Your “Go-To” Custom Install Speaker. The CI HOME series address the important considerations when selecting custom installation speakers: truly superior sound, trickle-down technologies, easy installation, and a bezel-free micro-perf grille with an incredibly discreet aesthetic.

Paradigm’s Exclusive Perforated Phase-Aligning (PPA™) Tweeter Lens

Protects the delicate tweeter dome. PPA™ technology acts as the Phase Plug, blocking out-of-phase frequencies for smoother, extended high frequencies with incredible detail and higher output. Ferro-fluid damped and cooled to ensure smooth high-frequency performance with amazing clarity across a wide listening area.

Dual-Directional Soundfield™ & 30°-Angled Guided Soundfield™ Models

Our Stereo/Mono (SM) systems offer rich pure-fidelity dual-channel L/R sound from a single speaker. The Dual Directional Soundfield™ provides wider-than-normal dispersion making the systems ideal in small rooms that are less suited to a stereo pair, or where a single speaker is preferred.
Drivers in our 30°-Angled Guided Soundfield™ sit at a 30° angle from the ceiling, enabling you to adjust the direction of the sound, without compromising the curial sound dispersion pattern between drivers and baffle, thereby preserving sonic integrity. 30°-Angled Guided Soundfield™ systems are ideal as front speakers and as surround and/or rear speakers in a home theatre system.

Other Features:

  • Pocketed screw holes help to hold the drill steady, making installation a snap. In addition, exclusive TORX-guided clamps protect against screw cam out and stripping.
  • Rigid ABS clamps simplify and reduce installation time. ABS sandwiches and strengthens the area around the mounting hole, removing unwanted resonance and vibrations.
  • Available pre-construction brackets and square grille accessories provide the utmost installation flexibility.
  • Superior Mineral-filled Polypropylene Bass/ Midrange Cones: Oversized computer optimized ferrite magnets and high-power motor structures deliver detailed midrange performance with clean, extended bass.
  • Easy-access binding posts: High-quality binding posts feature a larger wire access hole and connect via banana plug, pin or bare wire.
  • Magnetically attached grilles: neodymium magnets hold grilles firmly in place.
  • Bezel-Free, Micro-Perf Grilles allow you to mix and match CI Home, CI Pro and CI Elite Series for a seamless aesthetic from room-to-room!
