Power & Performance

• Design: 4-driver, 2 passive radiator, 3-way center channel, sealed enclosure
• Crossover: 2nd-order electro-acoustic at 2.5 kHz (tweeter/mid) and 2nd-order at 500 Hz (bass)
• Frequency Response (On-Axis): +/- 2 dB from 55 Hz – 23 kHz
• Frequency Response (30° Off-Axis): +/- 2 dB from 55 Hz – 17 Hz (some variants mapped to 20 kHz)
• Sensitivity (Room / Anechoic): 94 dB / 91 dB
• Impedance: Compatible with 8 Ohms
• Low Frequency Extension: 37 Hz (DIN)
• Suitable Amplifier Power Range: 15 – 260 Watts
• Maximum Input Power: 200 Watts
• Performance: The Paradigm Founder 90C is the ultimate flagship center channel speaker of the Founder Series, built to anchor elite home theater systems with absolute command. Measuring nearly three feet wide, this high-output acoustic titan handles up to 75% of a movie's soundtrack, including almost all dialogue and primary front-stage effects. By deploying a true 3-way coaxial layout paired with an ambitious bass system, it achieves a monstrous 37 Hz low-frequency extension. It is the definitive choice for premium large-scale dedicated theaters, delivering pristine dialogue intelligibility, lightning-fast transient snap, and massive dynamic weight that remains perfectly composed at stadium-level volumes.

Audio Features & Drivers

• 1-inch AL-MAC™ Ceramic Dome Tweeter: A proprietary coaxial composite dome fusing Aluminum, Magnesium, and Ceramic materials for light, ultra-rigid, and anti-resonant highs. It operates inside a mathematically profiled OSW™ (Oblate Spheroid Waveguide) and a patented PPA™ (Perforated Phase-Aligning) Lens with a Dual Gap Motor Structure to deliver crystal-clear high frequencies across a broad listening area.
• 6-inch AL-MAG™ Coaxial Midrange Driver: Enclosing the tweeter to form a true structural point-source acoustic center. Built with a specialized aluminum-magnesium alloy, a 2-inch high-temp multi-layered voice coil with an Apical™ former, and a Patented Dual-Sync™ Continuous Flux Motor, it renders whispered dialogue and vocals with vivid, lifelike accuracy.
• Two 7-inch CARBON-X™ Active Bass Drivers: These ultra-high-excursion woofers use a single-piece unibody carbon-fiber cone for supreme strength-to-mass ratios. Featuring a 1.5-inch multi-layered voice coil with a ventilated Apical™ former, they deliver massive low-frequency impacts without flexing.
• Two 7-inch CARBON-X™ Passive Radiators: Working in harmony with the active woofers inside an acoustic suspension enclosure. By replacing traditional ports with dual passive radiators, the 90C yields a profound low-end extension down to 37 Hz while completely eradicating the audible air turbulence or "chuffing" common in large center channels.
• Advanced SHOCK-MOUNT™ Isolation Mounting System: Both the coaxial mid/tweeter assembly and the active/passive bass drivers are mechanically decoupled from the front baffle panel using an elastomer suspension network to eliminate cabinet-induced vibrations and distortions.

Streaming & Connectivity

• Premium Dual 5-Way Binding Posts: Outfitted with heavy-duty, gold-plated terminal blocks built to handle thick audiophile bare wire, pins, or banana plugs. The configuration fully supports bi-amping or bi-wiring layouts to maximize mid/high separation and current management.
• Flagship Timbre Balancing: Meticulously voiced and matched to blend effortlessly with the flagship Founder 100F and 120H floorstanding towers. This ensures that as audio elements pan horizontally across your front wall, there is zero shift in tonal quality or voice depth.
• High-Current Amplifier Synergy: Boasting an efficient 94 dB room sensitivity, the 90C is easy to integrate with premium multi-channel AV receivers, though it truly unlocks its visceral low-frequency scale when backed by high-current separates.
• Digital Calibration Integration: Designed to pair perfectly with high-end Anthem® processing networks, allowing Anthem Room Correction (ARC®) to seamlessly calibrate the center speaker's output to counter room anomalies or home theater cabinetry boundaries.

Comfort & Dimensions

• Faceted Monolithic Geometry: The complex, angular cabinet structure isn't just a design statement; the non-parallel walls physically break up internal standing waves and prevent the cabinet enclosure from coloring or muddying the critical midrange field.
• Luxury Furniture Finishes: Hand-finished to premium standards, available in four gorgeous variants: Piano Black, Black Walnut, Midnight Cherry, and Walnut, allowing this substantial speaker to sit gracefully beneath flagship video displays.
• Overall Dimensions: 8.9” (22.6cm) Height x 35.7” (90.8cm) Width x 12.9” (32.7cm) Depth.
• Unit Weight: 48 lbs (21.8 kg) each — A heavy, remarkably dense mass reflecting the heavy-duty Cascade-Fusion Bracing, thick front baffle plane, and massive motor potting structures.
• Magnetic Micro-Perf Grilles: Packed with low-profile, sonically transparent cloth grilles that snap precisely flush against the front plane via hidden high-force magnets, preserving an immaculate aesthetic when the grilles are removed to display the intricate geometry of the PPA™ lenses.

Design & Build

• Cascade-Fusion Internal Bracing: Longitudinal internal bracing columns segment the interior walls into non-uniform areas, drastically fortifying structural rigidity to guarantee tight, punchy transients.
• Dual Gap Motor Topologies: The high-frequency driver assembly utilizes a dual-gap configuration to increase thermal power handling, suppressing dynamic compression artifacts during long-duration, high-output listening sessions.
• Handcrafted Heritage: Proudly conceived, engineered, and completely hand-assembled at Paradigm’s premier manufacturing infrastructure in Ontario, Canada, satisfying the tightest engineering tolerances in the industry.
• NRC Science Validation: Developed under the rigorous acoustic parameters laid down by the National Research Council (NRC), representing the scientific zenith of neutral, flat-line sound reproduction.
• Sealed Cabinet Versatility: The acoustic suspension and passive radiator setup allows the 90C to be placed deep inside custom home theater cabinetry or close to wall boundaries without inducing bloated bass resonances.
