    Dymension DM70 Large Tower Speaker

    Spacious, Room-Filling

    Dymension™ DM70 tower speakers deliver dynamic, room-filling sound with extended bass by leveraging Definitive Technology’s signature bipolar arrays, proprietary drivers, and integrated 10" subwoofers.

    Spacious, Immersive Soundstage

    Anatomy of an
    Iconic Speaker

    The Dymension DM70 fills your home theater with larger-than-life sound. Crystal clear highs, incredible depth-of-field, and thunderous bass envelop you, whether you’re enjoying the latest blockbuster film or your favorite songs. Innovations include aluminum oxide tweeters, an adjustable BDSS bipolar array, and an integrated powered subwoofer with 3XR technology.

      Fully Balanced,
      Adjustable Bipolar Array
      for a spacious,
      immersive soundstage

      Bipolar driver arrays direct more sound in more directions than traditional speakers, for incredible depth-of-field and a truly enveloping listening experience. Adjustable to optimize for room placement.

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

      Our 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.

      Built-In 10" Powered
      for thunderous bass

      An integrated 10” subwoofer, powered by an all-new, high-performance Class D amplifier, delivers clean, detailed bass that perfectly blends with mids and highs and feels consistent no matter where you sit.

      Aluminum Oxide
      for crystal clear highs

      New driver designs provide smooth extended response with crisp transients, exceptional definition, and pinpoint-precise imaging, for incredible clarity and lifelike realism.

      3XR Architecture with
      Dual Passive Radiators
      for seamless,
      balanced bass

      3XR Architecture combines a subwoofer and two passive radiators to produce huge, balanced bass that you can feel, with less distortion than traditional ported designs.

      Patented Intelligent
      Bass Control
      for precise low-end tuning

      Bass will never get in the way of dialogue and other critical soundtrack elements. Sophisticated digital processing seamlessly blends subwoofer output with mids and highs to provide powerful deep-bass performance without sacrificing midrange clarity.

      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.

      Included cabinet foot spikes and pads provide the ideal way to place and level DM70 speakers on virtually any floor surface, providing acoustic isolation and stability.
