About Definitive Technology UIW RLS III

Where elegance meets superior sound quality, the UIW RLS III 2-Way In-Wall Reference Line Source Speaker stands out as a sleek and modern addition to any home audio system. Crafted by Definitive Technology, a brand renowned for its high-quality audio equipment, this speaker is designed to deliver immersive, room-filling sound, making it an ideal choice for home theaters or multichannel music systems.

The UIW RLS III boasts dual 5.25" cast basket drivers, ensuring detailed audio presence, and two 5.25" pressure-coupled low bass radiators for deep, resonant bass. Its high-tech flush-mount enclosure seamlessly integrates into your living space, providing uncompromised cinematic performance without the clutter of traditional freestanding speakers.

This in-wall speaker is equipped with a 1" aluminum dome tweeter, delivering clear, precise high-frequency response. Its ultralight, rigid construction allows it to play frequencies beyond the audible range, ensuring distortion-free highs for an exceptional listening experience.

The speaker's 5.25" midrange/woofer drivers, featuring butyl rubber surrounds and rigid polypropylene cones in cast baskets, offer superior midrange and bass performance. Additionally, the inclusion of twin 5.25" passive bass radiators ensures more bass than comparably sized sealed or ported designs, providing a deeper low end that can seamlessly integrate with subwoofers at various crossover points.

Whether you're installing in new or existing construction, walls or ceilings, residential or commercial spaces, the UIW RLS III offers simple, secure installation. Its fully enclosed design, featuring dense, acoustically inert, anti-resonant Medite wood, ensures powerful sound exactly where you want it, without sound leakage into walls and ceilings. With its white color option, this speaker not only delivers high-quality sound but also adds a stylish, modern touch to your home decor.
