Summary
The Dymension Series is Definitive Technologies' latest loudspeaker line, launched to replace its older 9000 Series of speakers. Four tower models feature a Bipolar speaker array for a diffuse, large-soundstage experience. All four towers (in addition to the flagship center channel) carry variations of an active subwoofer section paired with bass radiators. New to the Dymension Series is an Intelligent Bass Control feature that attenuates bass output while altering DSP across the entire speaker's driver array.

We were particularly impressed with the Dymension Series bass abilities and its home theater playback prowess.


Definitive Technology launched its all-new Dymension Series of high-performance loudspeakers several weeks ago. Harnessing the advantages of a bipolar speaker design and active low-end drivers, the Dymension Series gives enthusiasts access to an entirely unique sound experience loaded with low-end character. The series consists of four different floorstanding speakers, three center channels, and two topper/wall-mountable Atmos channels. The entry-level DM40 tower is priced at $999 each, while the flagship DM80 costs $2499 each. Center channel pricing starts at $799 (DM10) and tops out at $1499 for the DM40 powered speaker.

AV NIRVANA visited Masimo Consumer's headquarters and spent extensive time listening to the Dymension Series. This video review includes a look at the series's more important technologies, new drivers, and impressions of the speakers in action. Give it a watch to learn about Def Tech's unique sound approach with Dymension speakers!
DM80 Flagship Tower Speaker Features:
  • Fully Balanced, Adjustable Bipolar Array: Bipolar driver arrays direct more sound in more directions than traditional speakers for incredible depth-of-field and a truly enveloping listening experience. Bipolar effect can be adjusted to optimize for room placement.
  • Built-In 12” Powered Subwoofer: An integrated 12” subwoofer, powered by an all-new, highperformance 400W GaN FET amplifier, delivers clean, detailed bass that perfectly blends with mids and highs and feels consistent no matter where you sit.
  • BDSS System and Linear Response Waveguide: DM80’s four 5.25” mid/bass woofers feature our patented Balanced Double Surround System™ technology (BDSS™). BDSS improves midrange driver excursion and provides a wide, uniform soundstage with seamless bass/mid integration. A Linear Response Waveguide™ extends and smooths off-axis dispersion for great sound everywhere in the room.
  • Patented Intelligent Bass Control: Sophisticated digital processing seamlessly blends subwoofer output with mids and highs to provide powerful deep-bass performance without sacrificing midrange clarity. Bass will never get in the way of dialogue and other critical soundtrack elements.
  • DM90 Integrated Height Module Option: Available separately, a DM90 Atmos-certified and DTS:X-compatible height module connects to the top of the DM80 to extend sound above you for total sonic immersion and hyper-realistic overhead effects.
DM30 Flagship Center Channel Speaker Features:
  • Advanced Five-Driver Array: Four 5.25" BDSS midrange woofers and a 1" aluminum oxide tweeter deliver ultra-clear vocals with uncanny realism. Add DM30's integrated 8” powered subwoofer and its full-range immersive sound that draws you into the action every time.
  • Built-In 8” Powered Subwoofer: An integrated 8” powered subwoofer delivers clean, detailed bass that perfectly blends with mids and highs, anchoring voices and effects with rich, fullrange sound.
  • 3XR Architecture with Dual Bass Radiators: 3XR™ Architecture—introduced in our flagship Descend Series—combines a subwoofer and two passive radiators to produce huge, impactful bass that’s unrivaled in a center channel speaker. Get ready to experience low end you can feel.
  • BDSS System and Linear Response Waveguide: The DM30’s midrange woofers feature Definitive’s BDSS™, which improves excursion and provides superior midrange detail. Our patented Linear Response Waveguide™ extends off-axis dispersion for total sonic immersion.

We have a 15.4 channel Definitive Technology Dymension Series speaker system in one of our new premium Cinema Demo Rooms. The projector is JVC's NZ8 and the receiver is Denon's new A1H 15.4 channel receiver and wow we are loving this Home Theater demo room!!
 
I’m sure it sounds great! I was certainly impressed with it as a home theater speaker!
 
Hope you will stop by to see our new suite of Cinema Rooms all with premium Dolby Atmos/DTS:X audio systems.
 
I will. It’s on my list for this spring/summer!
 
Thank you Todd!!
 
Hello, my current main speaker is KEF R7 Meta. I want to upgrade the center speaker. How should I choose between DT DM30, KEF R2 Meta/R6 Meta, and Polk L400? What are their advantages?
 
Hi @JakysonC, if by "main speaker," you're saying that your front left and right channels are KEF R7 Metas... then your only good choice is to stick with the KEF Meta series of speakers.

If you opt for the Def Tech or Polk models, you won't have proper timbre matching across your front soundstage. Our ears are sensitive to changes in mid- and high-frequencies... and the Polk/Def Tech speakers are going to have a different tonal spin on sound in those frequencies.

So, stick with KEF and make sure that the tweeters used in the KEF speakers are timbre matched to your KEF R7s. If you're unsure - contact KEF and confirm.

In looking at the KEF R2 Meta/R6 Meta... both are super intriguing because they use a point source driver for mids and highs. That helps to combat some of the common issues presented by the horizontal driver layout found on center channel speakers.

The DefTech model is super impressive because of its bass section. It can dig deeper than the KEF R6. Though, that's less of an advantage if you are running subwoofers in your set up.

If I were you, and if you're happy with the sound quality of the your KEF R7s... AND budget isn't a limiting factor... I'd confirm timbre matching on the KEF R6 and go with it. It has a better low end output as compared to the R2, which is going to give you some flexibility when it comes to playing around with the speaker's crossover point with the rest of your system.

I'm curious to learn more about your system... what other speakers do you have?

Thank you for the reply! My surround speakers are Definitive ProMonitor 800 / 400.And I have two jamo subwoofers.
 
Cool. Having different surrounds isn't as much of an issue. But definitely don't mix and match brands/tweeters across your front three speakers.

Are you happy with the KEF R7s?
