Definitive Technology Dymension DM90

The DM90 modules are specifically engineered to snap into the top of Definitive Technology's Dymension series floor-standing towers. They are not universal add-ons and will not fit other speaker brands or older Definitive Technology models.

No. The DM90 features a clever snap-in design that includes integrated electrical connectors. Once you place the module on top of a compatible tower, the signal is passed through automatically, keeping your setup clean and free of visible wires.

The DM90 uses an upward-firing driver configuration to bounce sound off your ceiling. This reflection creates the illusion that audio is coming from above, which is essential for immersive surround sound formats like Dolby Atmos and DTS:X.

These modules perform best with flat, reflective ceilings that are between 7 and 12 feet high. If your ceiling is vaulted, angled, or heavily textured, the sound waves may not reflect accurately, which can diminish the immersive height effect.

The DM90 modules are designed to handle between 25 and 100 watts of power. Since they are driven by your main tower's amplifier channel, ensure your receiver or amplifier is capable of powering your tower speakers effectively.

These are strictly designed for home theater applications. They are intended to reproduce height channels in surround sound mixes, so they will not provide a standard stereo listening experience on their own.
