Dymension™ DM80 Flagship Tower Speaker

Expansive, Room-Filling

Dymension™ DM80 tower speakers deliver dynamic, room-filling sound with extended bass by leveraging Definitive Technology’s signature bipolar arrays, proprietary drivers, and integrated 12" subwoofer.

Spacious, Immersive Soundstage

Anatomy of an
Iconic Speaker

The Dymension DM80 fills your home theater with dynamic, expansive sound. Crystal clear highs, incredible depth-of-field, and thunderous bass envelop you whether you’re enjoying the latest blockbuster or your favorite songs. Innovations include aluminum oxide tweeters, an adjustable Balanced Double Surround System (BDSS) bipolar array, an integrated powered subwoofer with 3XR Architecture, and a cutting-edge GaN FET amplifier.

    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 12" Powered
    for thunderous bass

    An integrated 12” subwoofer, powered by an all-new, high-performance GaN FET 400W 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
    for precise low-end tuning

    With the DM80, bass will never get in the way of dialogue and other critical soundtrack elements. Sophisticated digital processing 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.

    Stability and versatility for flexible placement
