About the Definitive Technology UIW RLS II

Kramer Crane

Hear it all, see almost nothing

I'm a big fan of Definitive Technology's design philosophy — they have a knack for creating slim speakers that deliver surprisingly spacious sound. The in-wall UIW RLS (Reference Line Source) II is a great example of this. It can give you the kind of big, revealing sound you'd expect from a conventional Def Tech speaker, but without taking up any floor space.

Hear it all, see almost nothing

I'm a big fan of Definitive Technology's design philosophy — they have a knack for creating slim speakers that deliver surprisingly spacious sound. The in-wall UIW RLS (Reference Line Source) II is a great example of this. It can give you the kind of big, revealing sound you'd expect from a conventional Def Tech speaker, but without taking up any floor space.

Use this versatile speaker as a left-, right-, or center-channel speaker in your home theater. Or use a pair as part of a high-end, custom-installed stereo system. The drivers are specially configured to provide optimal performance whether you mount the speaker vertically or horizontally.  

Definitive Technology Reference Line Source UIW RLS II in-wall multi-purpose speaker with built-in back-box

The integrated sealed enclosure helps deliver excellent sound while keeping dust and dirt away.

Excellent sound, no matter what's behind your wall

One of the challenges that in-wall speaker designers face is that they don't know how much air space is inside your walls (or in other words, how big or small your speaker “cabinet” is).

Definitive Technology has a great solution for this — an airtight, built-in wooden back-box that helps the speaker deliver focused, dynamic sound no matter what space is behind your wall. 

The back-box also helps prevent sound from leaking through to an adjacent room, like when you're watching a movie at night while the kids are asleep. 

DIY installation

You can paint the included grille to have your speaker blend in with your room's décor. If this is a do-it-yourself install, check out our guide to installing in-wall speakers, along with our selection of in-wall speaker wire.

Features

2-Way Driver Design: The Definitive Technology RLS II in-wall loudspeaker features a 2-way driver design with a 1" pure aluminum dome tweeter and two 6.5" polypropylene cone woofers, plus two 6.5" pressure-driven bass radiators. A precision crossover system provides seamless driver blending for a smooth open sound with with wide soundstage.

Non-Resonant Sealed Enclosure: The RLS II features a non-resonant sealed medite (a dense wood product) enclosure to deliver the tight, detailed bass and uncolored midrange of audiophile free-standing speakers in every installation. The performance of open back built-in speakers will vary depending on the nature of the ceiling cavity behind the speaker. But Definitive Reference series speakers with integrated enclosures sound superb every time.

Paintable: The UIW RLS II in-wall loudspeaker's grille and frame can be spray painted to match the color of your wall without any loss of sound quality. Simply remove the grille from the speaker and place it on a drop cloth, newspaper, or plastic sheet and spray paint it with canned spray paint that closely matches the desired finish/color (available at home improvement stores). A paint mask is supplied to protect the drivers when painting the frame.

Spring-Loaded Speaker Terminals: The UIW RLS II in-wall loudspeaker features a pair of heavy-duty, gold-plated, spring-loaded posts designed to accept up to 10 gauge wire, banana plugs (single only), or pin-connectors.

Applications: The Klipsch UIW RLS II is intended for use as an in-wall front main left, center or right channel speaker, as well as a rear or side surround speaker in custom installed home theater systems of the highest quality. In addition, it can be used as a superb left or right speaker in a high quality stereo music system.

In-Wall Installation: Eight rotating dogleg clamps and four 3.5" wood screws make the RLS II easy to install in either new or existing construction and provide secure, non-resonant mounting for ultimate audiophile performance free of vibrations and buzzes. In-wall installation requires a cutout of 7.0" (w) x 28.5" (h) x 3.875" (d). A 1" of clearance is required around the cutout, on the outside mounting surface, to clear the in-wall speaker's bezel. A 1.25" of clearance is required inside the wall, around the cutout, to clear the rotating dogleg clamps.

Customer Q&A

4 questions already asked

Q
Since the Def Tech UIW RLS II is self enclosed, would it be possible to mount this speaker on the wall rather than in the wall?

A
Greetings Chad, and thank you for your question. The UTW RLS II does not have any on wall mounting key hole slots, so mounting in the wall would be more of a custom application.

Q
Can this speaker be installed in ceiling?
heidi  Jun 16, 2022

A
Yes, this speaker can technically be mounted in the ceiling. Keep in mind that it is a fairly heavy speaker at approximately 19 lbs.
