Complement your flat-panel TV with this slender center speaker

Build a complete on-wall speaker system for your flat-panel TV using the slim Mythos Seven as the center channel. It uses many of the same technologies found in Definitive's Mythos floor-standing speakers to provide a wide soundstage with pinpoint imaging, crystal-clear dialogue, and superb realism. And at just over 4" deep, this center channel speaker is made to be wall-mounted below today's slim TVs.

Grille off shot

High-tech drivers for exceptionally detailed sound


Close-up of the pure aluminum dome tweeter.

At the center of the cabinet are two 3-1/2" midrange drivers surrounding a 1" dome tweeter. The pure aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess. Flanking the midranges are two 3-1/2" bass radiators, which give the Mythos Seven better bass performance than you might expect from such a slim speaker. Die-cast aluminum baskets, a resonance-free PolyStone baffle, and proprietary damping technologies built into the cabinet ensure clean sound.

Gorgeous aircraft-grade aluminum cabinet

The enclosure is made of black hand-polished aluminum for a sleek look that'll go well with most modern décors. The Mythos Seven comes with a wall-mounting bracket that will adapt to most swing out, arm-style TV wall mounts, so the speaker moves along with your TV when you reposition it. And a rubber-tipped adjustable foot on the bottom of the cabinet allows you to aim the speaker upwards towards your listening position when placed on a low shelf.

Building a system

Team up the Mythos Seven with two Mythos Five floor-standing speakers or two Mythos Six on-wall speakers for the left and right channels, and the Mythos Gems as surround speakers. Add Definitive's SuperCube II, SuperCube III, or ProSub 800 subwoofers for hard-hitting bass.

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.

Your home theater's most important speaker

The center channel speaker is the workhorse in a home theater system. It has to reproduce clear dialogue and special effects that keep your eyes and ears glued to the movie action. A high-quality center speaker is a great investment for any surround sound setup. Try to choose one that's as closely matched as possible to your front right and left speakers, so that as sound moves across the front stage, it stays seamlessly realistic.

Product Research

Overview: The Definitive Technology Mythos Seven Center-Channel Speaker is the perfect center-speaker solution for your home theater system and flat-panel television. The Mythos Seven center-channel speaker features two high-definition 3-1/2 inch drivers pressure-coupled to two 3-1/2 inch planar low-bass radiators, and a 1-inch pure aluminum dome tweeter with an acoustically contoured faceplate high frequency extension, detail, and smoothness. The Mythos Seven features a hand-polished gloss aircraft-grade extruded aluminum enclosure with proprietary damping technologies to ensure total rigidity and accurate sound. The Mythos Seven center-channel speaker also includes a wall-mounting bracket and an adjustable foot.

Driver Technology

Speaker Array: The Definitive Technology Mythos Seven contains a D'Appolito array consisting of two high-definition 3-1/2 inch drivers housed in a air-tight enclosure. The drivers feature die cast Aluminum baskets, mono-polymer cones and finite element analysis optimized magnet structures for clear low distortion life-like sound. The drivers are pressure-coupled to two 3-1/2 inch planar Low-Bass Radiators for exceptional bass extension not normally found in slim on-wall loudspeakers of this size. The bass roll-off of the Mythos Seven is smooth and controlled, allowing it to seamlessly blend with a powered subwoofer, such as Definitive's SuperCubes, for audiophile-grade home theater power and precision. A 1-inch Pure Aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess.

Break-In Period: The Mythos Seven will sound good right out of the box; however, an extended break-in period of 20-40 hours or more of playing is required to reach full performance capability. The break-in period allows the suspensions to work in and results in full bass, a more open midrange, and smoother high frequency reproduction.

Enclosure Design

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


Binding Posts: The Mythos Seven is equipped with a pair of gold-plated, 5-way binding posts to attach your receiver's speaker wire.

Mounting Options

Placement: The Mythos Seven is designed for horizontal use and can be used as either a front or rear center-channels speaker. As a center-channel speaker, the Definitive Technology Mythos Seven can be placed above or below your television.

Mounting: The Mythos Seven is a table/shelf-mount and on-wall center-channel speaker. The Mythos Seven come with easy-to-install mounting hardware that allows it to mount on the wall above or below your television. The Mythos Seven comes with a wall mount bracket that allows direct mounting to a wall and also adapts to flat panel TV swing out arm-style wall mounts so that the speaker angle changes with the TV angle. It also includes hardware that allows you to place the speaker on the TV, on a shelf , or on a table top (surface must be at least 5-inches deep).

Angle Adjustment: The Mythos Seven has a simple built-in device which allows you to adjust the vertical angle of the speaker. There is an adjustable rubber-foot on the bottom-rear of the speaker cabinet. when you set the center-channel speaker down, the speaker will lean back and rest on this foot. By varying how far you screw in-and-out the foot, you can adjust the vertical angle of the speaker. It is recommended that you aim the center-speaker so that it aims directly towards the height of the listeners' ears.

Nice speaker

Written By DJ, Ohio on Sunday, March 22, 2015

Crutchfield Customer Review (What's this?)

Was looking for a good speaker to fit in a tight space and this definitely fills that need. It is very slim and compact but still has great sound, especially for the size. Price was reasonable as well.

Pros: Compact, low profile, great looking, impressive sound

Cons: None

Written By Sean, Arizona on Saturday, January 10, 2015

Crutchfield Customer Review (What's this?)

Really nice center speaker. I have a large room, and would have liked a larger center, but this was the only one that would fit under my tv. Initially, I was not too impressed, but after a few days, the speaker really started to open up and I got the clarity I was looking for in a center channel. If you have limited space, give this a try.

Pros: Compact, fits under my tv

Cons: None

at last!

Written By Sea4Me, VB, VA on Saturday, August 30, 2014

Crutchfield Customer Review (What's this?)

Just what I needed. If you're balancing what you want vs what you need, you expect to make sacrifices. Well, it was hard to find the right size center channel & I was open to paying a premium for the fit rather than give up the form of my room. Luckily, I found this speaker. Sounds amazing, nice low profile, not an overwhelming price. I feel like I have both form (the appearance of my living space) and function (and awesome sounding system) for my new Samsung Plasma 64" Glad you're here, Definitive! (And thanks for the lightening fast shipping, Crutchfield!)

Pros: low profile, clean lines, crystal clear sound

Cons: haven't found any struggles yet...will see what happens as I push this speaker

Written By Sdarrow, Santa Barbara on Saturday, March 22, 2014

Crutchfield Customer Review (What's this?)

Purchased the mythos 7 for my center speaker to go along with two mythos 6's that I am using as my front left and right. Overall, very happy with style and performance for the price/size.

Pros: Great style and low profile.

Cons: none

Ok for main speaker at low volumes

Written By JeffN, Van Buren, AR on Wednesday, January 15, 2014

Crutchfield Customer Review (What's this?)

I purchased this to be the main center channel speaker in a mid-priced system in my family room. It can distort at louder volumes, but is fine for "normal" TV levels. Given its small size, this is an accomplishment. I think it would take a considerably larger speaker to play at movie levels.

Pros: Small, I don't have room for a deeper speaker. Good looking.

Cons: I wish I could drive it harder without distortion.

Nice sound

Written By BReeves780, Nashville, TN on Sunday, December 29, 2013

Crutchfield Customer Review (What's this?)

I bought 2 Mythos Six and a Seven along w/ a ProSub 800 for center, side & sub speakers for a new Samsung plasma and although they're still new to me, I really like the sound of the outer speakers. The Sub is a little bit "all there or not" but the Mythos' are all great...look and sound terrific.

Pros: NIce look, compact, great sound

Crutchfield Customer Review (What's this?)

Great sound quality in a compact unit

Pretty good - could be "larger" sounding

Written By Kevin, Palo Alto, CA on Wednesday, September 18, 2013

Crutchfield Customer Review (What's this?)

I got these after five years of requests to downsize my Polk RTi A6s from the wife; they sounded amazing but were just too massive. I tried the Klipsch G-42 passive soundbar first but was dismayed at how pathetic it sounded compared to my beloved Polks. Sent it back to Crutchfield and called up to ask what they would recommend. Two different salespeople pointed me to Definitive Technologies and holy cow am I glad that they did.

I got this speaker to complement a pair of Mythos Gem XLs on L & R fiddle; it balances the sound very well and gives great dialogue when watching TV. I am a little disappointed in the "size" of the sound, however - unlike the Gem XLs, I can tell when I listen to it that the sound is being pushed through a pair of 3 1/2" cones...passive radiators or no.

If you have the space for it and the extra hundred bucks, jump up to the next Definitive Technology center channel CS-8040HD instead. I would, but the form factor doesn't work for my setup. Given my constraints, this speaker sounds better than anything else by a long shot. I just wish I had the space to get a slightly larger center channel in place.

Written By TomD, Jacksonville, FL on Saturday, June 08, 2013

Crutchfield Customer Review (What's this?)

Not a lot of oomph in this center speaker, but it's pretty good for its size. If you need a good center speaker that is only 4 inches high, this is a decent choice.

Pros: Good if space if space is limited.

Cons: Could use a little more bass or richness. If the size of the speaker is not a factor, you might want to upgrade to the Mythos Nine.

Crutchfield Customer Review (What's this?)

I was looking for a quality center speaker that was powerful however small in size. This speaker did not disappoint. Quality sound. Perfect size. Nice looks.

Pros: Size and sound quality.

Crutchfield Customer Review (What's this?)

This was my first time ordering from Crutchfield, and I was impressed to say the least. I was kept up to date on my order status as it progressed.

The Definitive Mythos 7 fits perfectly in front of my LED Samsung and sounds amazing. The voices sound like they reach out into the room. I needed a low profile center channel speaker and this one fits the bill perfectly without sacrificing sound quality.

Written By Anonymous, Woolwich NJ on Sunday, April 04, 2010

Crutchfield Customer Review (What's this?)

I am slowly rebuilding my surround sound system. This speaker was the start. The center channel is where most of your experience begins. I am not sure what will be next. I love the Mythos item. Quality is the focus. I always buy quality versus name. Next will be replacing the L-R front and subwoofer. Or maybe my Onkyo receiver to be all HDMI. If Crutch keeps their prices inline, they are the way to buy.
