About Definitive Technology UIW RSS II

From the esteemed lineage of Definitive Technology's Reference Architectural Series, the UIW RSS II 3-Way In-Ceiling/In-Wall Reference Bipolar Speaker emerges as a pinnacle of audio innovation and high-quality sound. This speaker is meticulously crafted for audiophiles seeking an immersive surround sound experience in custom-install home theater systems, ranging from 5 to 9 channels or more. Its advanced design is optimized for use as rear or side surround sound speakers, ensuring a cinematic ambiance that rivals commercial theaters.

The UIW RSS II boasts a non-resonant sealed Medite enclosure, which is engineered for seamless flush installation into walls or ceilings, making it an ideal choice for both new constructions and existing spaces. The stylish white finish complements any interior design, offering a durable and discreet audio solution that blends into the aesthetics of your home.

Featuring a unique curved angle bipolar array, the speaker excels in delivering a harmonious blend of direct and ambient sound. This innovative configuration ensures precise sound localization and specificity, while also enhancing the spaciousness of the audio, making it perfect for both high-definition movie soundtracks and the nuanced layers of musical performances.

The pure aluminum dome tweeters, a signature of Definitive Technology, are designed with magnetic fluid-cooling and moving-coil mechanisms. This advanced technology combines the clarity of metal domes with the smoothness of soft domes, resulting in detailed, clear, and accurately imaged high frequencies.

For the midrange and bass, the speaker is equipped with high-definition cast-basket drivers that offer significant advantages in terms of bass reproduction and dynamic range. The aerodynamic, magnetically inert, non-resonant cast baskets are crafted to minimize sound reflections and maintain structural integrity, delivering a lifelike midrange clarity.

The rigid, non-resonant, glass-filled low-profile frames are another testament to the speaker's innovative design. These frames defeat diffraction and minimize resonance or coloration, ensuring that the UIW RSS II maintains sonic purity and projects a wide, dynamic soundstage.

As part of Definitive Technology's commitment to versatile and superior sonic performance, the UIW RSS II is compatible with a wide array of other Definitive Technology loudspeakers. This allows for a seamless integration and mix-and-match capability with floor-standing speakers and other in-wall or in-ceiling models, catering to any custom installation need.

In conclusion, the UIW RSS II 3-Way In-Ceiling/In-Wall Reference Bipolar Speaker with 2x 4.5" Woofer is a testament to Definitive Technology's dedication to advanced, high-quality audio solutions. It is the perfect addition for discerning listeners who desire a sophisticated, invisible home theater system that delivers definitive performance and transforms any space into a vibrant hub of entertainment.
