Our take on the Definitive Technology XTR®-20BP

by Kristen Schaub
Definitive Technology

You've just filled your shopping cart with a gorgeous set of skinny on-wall speakers for the front of your room...but what about the back? The compact XTR-20BP surround speaker perfectly matches Definitive's award-winning XTR series speakers, so you can enjoy the same ultra-shallow speaker look for your entire home theater. Plus, this speaker boasts the same rich, realistic sound and wide soundstage as its larger siblings.


State-of-the-art driver design for impressively accurate sound

The XTR-20BP uses two 3-1/2" XTDD drivers angled in opposite directions to broaden the midrange dispersion, creating a diffuse soundfield that will envelope you in the on-screen action. These shallow drivers optimize every part of the speaker surface to maintain a high level of performance. At the center of the baffle is the same pure aluminum dome tweeter used in Definitive's flagship speakers. It produces extended highs, revealing nuance and shimmer without a trace of edginess.

Building an XTR system

The XTR-20BP's enclosure is made of black hand-polished aluminum for a sleek look that'll go well with most modern décors. It comes with an easy-to-use wall mount bracket that gives it a mounted depth of just 2-9/16". It also comes with a convenient base for when you want to use it on a shelf or table. Put together a complete home theater system using XTR-40, XTR-50, or XTR-60 speakers for your front three channels. Then use the XTR-20BPs for surround channel duties, and you'll be rewarded with spacious and enveloping surround effects. And for high-impact bass, check out these Definitive subwoofers.


Got wire?

Most speakers don't include any. Learn about choosing and installing speaker wire at the Crutchfield Learning Center.

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

The Definitive Technology Mythos XTR-20BP features two angled 3-1/2" XTDD mid/bass drivers and one pure aluminum 1" dome tweeter for excellent high frequency extension and midrange detail. The Mythos XTR-20BP features a slim extruded aluminum enclosure which measures only 2.5" deep.

Driver Technology

Bipolar Design: Bipolar speakers can be utilized to spread sound over a wider area. The Mythos XTR-20BP surround speaker contains two 3-1/2 inch XTDD mid/bass drivers that are angled (at 16°) in opposite directions to broaden the midrange dispersion for a spacious and enveloping surround effect. Bipolar speakers fill the room with an enveloping sound, creating the illusion of multiple speakers surrounding your entire room. Using bipolar speakers as surrounds or surround back speakers creates an experience that seems larger than your room.

Pure Aluminum Dome Tweeter: The Mythos XTR-20BP features a center-mounted, pure aluminum 1" dome tweeter. The pure aluminum dome tweeter provides clarity, dynamic range, and extended high-frequency response.

XTDD Technology Drivers: The Definitive Technology Mythos XTR-20BP surround speaker utilizes Definitive's patent-pending XTDD technology anodized Aluminum dome driver for extraordinary performance. Using state-of-the-art computer modeling and decades of speaker design experience, Definitive engineers eliminated every inch of wasted space, optimized every part, and maximized the moving surface area of a dynamic driver to shrink it down to a very compact dimension without giving up ultra high performance audio fidelity. The XTDD drivers provide dynamic punch, a wide frequency range, and broad dispersion that flat vibrating membrane panel-type speakers simply cannot match.

Timber Matched: The Mythos XTR-20BP bipolar surround speaker is timber matched for use with the Definitive Technology Mythos XTR series LCR speakers.

Enclosure Design

Extruded Aluminum Enclosure: The Mythos XTR-20BP features a hand-polished, gloss-black, aircraft-grade, extruded aluminum enclosure with proprietary damping technologies that ensure total rigidity. All components of the speaker are mounted on a resonance-free PolyStone baffle. These rock-solid construction technologies along with state-of-the-art drivers and tweeter serve to deliver classic Definitive Technology sound quality: wide soundstage, spacious imaging, high dynamic impact, and superb realism.

Magnetic Grille: The Mythos XTR-20BP bipolar surround speaker features a black cloth magnetic grille which easily attaches and detaches from the speaker.

Connections

Speaker Terminals: The Mythos XTR-20BP bipolar surround speaker is equipped with a plug-in C-clamp speaker terminal to attach your receiver's speaker wire (up to 14 AWG).

Mounting Options

Applications: The Mythos XTR-20BP bipolar surround speaker can be used as a surround speaker and surround back channel speaker in a 5.1 or 7.1 channel configuration. 

Tabletop Placement: The Mythos XTR-20BP surround speaker can be placed on a table, shelf, or stand in a horizontal or vertical orientation. The XTR-20BP can be simply laid on its side to place the speaker horizontally. A vertical foot-stabilizer is included to rest the speaker vertically.

Wall Mounting: The XTR-20BP can be mounted directly to the wall using the two key-hole slots on the back of the enclosure and the included wall-mount bracket (mounting screws sold separately). The Mythos bipolar surround speaker can be mounted on the wall horizontally or vertically. There is also a single 1/4"-20 threaded screw insert on the back of the speaker's enclosure, if you wish to use an optional articulating wall-mount bracket (sold separately).

Note: A horizontal and vertical template is supplied to help with installation.

Excellent little speakers

Written By John B, Phoenixville, PA on Friday, March 21, 2014
Crutchfield Customer Review (What's this?)
 
I purchased this set as rear speakers for my home setup, and replaced a set of Bose rear speakers. These, coupled with the front and center channels of the same design are an amazing setup. The sound is clean and crisp with no noticeable distortion even at reference levels, and have a wide range. I would highly recommend them to anyone looking for a low profile wall mounted speaker.
Pros:
Small, well built metal chassis, great sound, easy hookups.
Cons:
None
