Paradigm Signature SIG-1.5R-30 Round In-Ceiling 2-Way Speaker v.2

It’s not often that Paradigm makes a fuss about removing something from a speaker but this is one of those times. The whole point of ceiling speakers is in the aesthetic. When customers choose Paradigm in-ceilings, it’s a given they want to hear great sound, they just don’t want to see it. Paradigm complied, making their virtually invisible in-ceiling bezels even less visible across the Signature Series in-ceiling lineup. The odd time you look up at the ceiling, there won’t be much to see ... which is exactly what you’re looking for!

Thinner, Sleeker Bezels with more transparent scrim for a cleaner, disappearing aesthetic with increased sonic transparency.

Low-density NLC Non-Limiting Corrugated thermoplastic elastomer TPE Surround, trickle down technology from Paradigm's Signature Series. FEA optimised and overmolded onto the polypropylene cone.

In concert with the new motor structure Paradigm has achieved double the power in these models! + 3dB! The speaker now plays louder. The thermoplastic elastomer is ten times more effective than standard elastomers in damping vibrations and resonances and the corrugations increase peak-to-peak excursion. The Guided Soundfield model is the only model physically able to accommodate the size and quantity of corrugations needed and the larger motor structure.

Motor Structure Includes a Three-Split Voice Coil, thicker top plate and larger ceramic/ferrite magnet. The new structure further improves low-frequency sound distortion at high excursion while maintaining the much-lauded frequency response of the previous generation. The speaker can play significantly louder now, but without a hint of compression/distortion.

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 aluminium, titanium and even diamond. Performance is clear, uncoloured and completely uncompromised.

Cutting-Edge Co-PAL Cobalt-Infused Pure-aluminium 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 optimised ceramic ferrite or neodymium magnet / motor structures with focused-field geometry.

Combination Ultra-Rigid Die-Cast Chassis and GRIP Glass-Reinforced Injection-Molded Polymer Bracket. Supremely rigid structure reduces resonances and standing waves. The use of an aluminium chassis allows the chassis to function as a heatsink.
