Ultra-Compact Lifestyle Models

How do you achieve the performance caliber of Paradigm Reference Signature in such ultra-compact models as the Signature S1, C1 and ADP1? The answer? Enclosure design must play a critical role.

All parts (baffle, rear and shell) on these compact cabinets are die-cast aluminum. The die-cast design also functions as an effective heatsink. Bass/midrange (S1) and bass driver (ADP1) baffles and chassis are physically integrated allowing space for a powerful 155-mm (6 in) driver. Cabinet interiors reveal heavy wall construction and extensive internal bracing. Constrained Layer Damping (CLD), a technique used extensively and with great success across aviation and naval platforms, is used in conjunction with a sophisticated Permacote® Linacoustic® to completely subdue stray residual vibrational energy within the cabinets. The end result? All of the high-end performance found in a much larger Signature Series speaker, in a significantly smaller package.


P-Be™ Pure-Beryllium Tweeter Domes. Pure beryllium was chosen for its exceptional thermal, physical and mechanical properties: lighter than diamond or aluminum with unmatched rigidity. Response is instantaneous and extraordinarily uniform. Elevating the dome promoted optimal off-axis dispersion.

ARB™ Aperiodic Resonance Breakup Fins. Die-cast aluminum fins in rear damping chamber capture and quickly disperse residual internal resonances, rendering them inert.

Co-PAL™ Cobalt-Infused Anodized Pure-Aluminum Midrange Cones. Combine high stiffness-to-mass with superior internal damping for an even greater degree of accuracy. The result is smooth, uncolored frequency response.

Premium Finishes. Signature Series enclosures are enhanced by a choice of two stunning wood veneer finishes — Cherry and Piano Black.
