Technology, by definition, is the practical application of knowledge. When it comes to sound reproduction, no one knows more than Paradigm. When it comes to the practical application of that knowledge we’re committed to doing it better! Better measurements, better materials, better components always result in better sound … and better speakers.

While many speaker companies do not have the resources to design and manufacture their own drive units, Paradigm purpose-designs robust drivers for specific speakers.

 


 

To ensure superb consistency, our crossovers boast hand-selected precision parts.

Our high-power, high-current amplifiers with oversized power supplies and massive heatsinks deliver tremendous (and instantaneous) power output at all times.

Use your knuckles! Rap on our enclosures! As one reviewer asserted, they’re as dead as we claim in our literature! Acoustically inert high-density hardboard reinforced by strategically located radial braces limit unwanted resonances and increase enclosure stiffness. At other times, no bracing is even required on our speakers, even on our most powerful subwoofers as they pound out the deepest, loudest bass imaginable … it’s all in the design!

Custom speakers, often referred to as architectural speakers — designs hidden out of sight in a wall or ceiling (for those who don’t have the space or want a minimalist approach to music and home theater) — are growing in popularity. Again, Paradigm is leading the way in this area. When it comes to in-wall/in-ceiling speakers, there is no substitute for good design build on years of experience producing the very best sounding freestanding designs. More than 25 years of intensive research and design backed by cutting-edge technology, much of it proprietary, lie behind every custom speaker we produce. The result? Sound reproduction that rivals that of the very best freestanding designs.

Precision. Consistency. Long-term reliability. These are inherent characteristics of even the smallest Paradigm component part. Technology and design that represent true innovation in the pursuit of perfection in audio reproduction. Out of this come sonic accuracy and purity, a clean, detailed and transparent reproduction of the original performance, nothing more, nothing less.

It starts with knowledge, it ends with knowing, knowing that you’ve created a better product … an audibly better product. You hear it in every Paradigm speaker produced!

SIG-1.5R

2-driver, 2-way in-ceiling / in-wall, GRIP™ chassis / mounting bracket


Overview

Signature Custom Sound … Our Commitment to Audio Perfection is Written
All Over It!

Moves in-wall / in-ceiling sound beyond the ordinary to the truly extraordinary … Signature Custom sets the ultimate standard for what can be expected, achieved and actually delivered by a speaker system installed in a ceiling.

Full-Perimeter Bracket Design. Unlike typical mounting ears, brackets cover the full diameter or height and width of the speaker chassis to effectively sandwich and strengthen the area around the mounting hole.

Cutting-Edge P-Be™ Pure-Beryllium Domes. Exotic beryllium! The metal of choice for truly ultimate levels of high-frequency performance. A stiffness-to-density ratio superior to metals such as aluminum, titanium and even diamond. Performance is clear, uncolored and completely uncompromised.

Cutting-Edge Co-PAL™ Cobalt-Infused Pure-Aluminum Cones. Combine high stiffness-to-mass ratio with superior internal damping for an even greater degree of accuracy. Advanced Nomex® cloth suspensions and butyl rubber surrounds promote superb and extended excursion.

Cutting-Edge Mineral-Filled Co-Polymer Polypropylene Bass Cones. Superior stiffness-to-mass. Precision-engineered for higher sensitivity, power handling and ultra-low levels of distortion. Massive optimized ceramic ferrite or neodymium magnet / motor structures with focused-field geometry.

High-Strength GRIP™ Glass-Reinforced Injection-Molded Polymer Chassis / Mounting Bracket. Increased strength and design rigidity reduce resonances, vibration and flexing dramatically!
