    Dymension DM90 Integrated Height Module

    Seamless Overhead

    The Dymension™ DM90 height module attaches to Dymension DM80 and DM70 bipolar tower speakers to provide overhead sound in immersive Dolby Atmos and DTS:X systems.

    Total Sonic Immersion

    3D Sound

    The DM90 integrated height module attaches to Dymension DM80 and DM70 bipolar tower speakers to provide upward-firing drivers that make the towers Dolby Atmos and DTS:X-enabled. With DM90s attached to DM80 or DM70 speakers, you can create the immersive sound system of your dreams.

      Add-On Modules
      for Dolby Atmos and DTS:X 3D overhead audio

      An upward-firing mid/bass woofer and tweeter project sound toward the ceiling where it reflects back to you, providing a sense of height that translates to a more immersive listening experience.

      Plug-and-Play Integration
      for easy, quick, secure

      An easy snap-in connection system makes electrical connections and secures the height module to the top of Dymension DM80 or DM70 bipolar tower speakers.

      BDSS System and Linear Response Waveguide
      for smooth midrange and lifelike imaging

      Patented Balanced Double Surround System (BDSS) technology improves the midrange and provides a uniform soundstage with seamless bass and mid integration. A Linear Response Waveguide™ extends and smooths off-axis dispersion for great sound everywhere in the room.

      Aluminum Oxide Tweeter
      for crystal clear highs

      A new driver design provides smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.

      for seamless Definitive
      Technology sound

      Consistent sound across other Definitive Technology series gives you the flexibility to mix and match Dymension™ and all Definitive Technology in-wall and in-ceiling speakers to design your dream home theater and whole-home system.

      Manufacturer’s Pricing Policy

      Why do I need to contact you in order to place my order?

      As an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

      Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

      If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer.

      What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.

      If you have any questions regarding a specific product, please do not hesitate to contact us at (888) 392-4814.
