Choosing Definitive Technology Speakers

1. Match speaker type to role

   You must select the correct speaker type for your specific audio role. Center channels handle dialogue, while towers provide full-range sound. The Definitive Technology Dymension DM20 is a dedicated center channel. It measures 30.5 inches wide and fits above most TVs. The DM40 is a floorstanding tower. It stands 37.4 inches tall. Choose a center channel if you need clear voices. Choose a tower if you need main left or right speakers. Do not mix roles in the same position.

2. Check physical dimensions carefully

   You need to verify the physical size before buying. The DM20 center channel is 30.5 inches wide. It is only 5.3 inches high. This slim profile suits tight entertainment centers. The DM40 tower is 10.3 inches wide. It is 37.4 inches tall. This narrow depth fits in small rooms. The CS-9040 is 20.8 inches wide. It is 12 inches deep. Measure your space first. Ensure the width and height fit your shelf or floor area. Check the depth for clearance behind the unit.

3. Consider weight for mounting

   You must check the weight if you plan to mount the speaker. The DM20 weighs 22.1 pounds. This is heavy for a wall mount. Ensure your bracket supports this load. The DM40 weighs 38.1 pounds. It is designed for the floor. Do not attempt to mount this tower. The CS-9040 weighs 20 pounds. It is lighter than the DM20. Check your wall anchors and brackets. Heavy speakers require sturdy mounting hardware. Verify your wall can support the specific weight listed.

4. Look for integrated bass solutions

   You should check how the speaker handles low frequencies. The CS-9060 includes a 150W subwoofer. This provides deep bass without extra components. It weighs 26 pounds. This is heavier than the passive CS-9040. The CS-9040 uses a passive radiator. It relies on your amplifier. The DM20 and DM40 do not list integrated subs. If you want bass from the center channel, the CS-9060 is the choice. Otherwise, use external subwoofers for other speakers.

5. Verify color and finish

   You need to ensure the color matches your room. All listed Definitive Technology models are black. The DM20, DM40, CS-9040, and CS-9060 are all black. This ensures a uniform look if you mix models. The DM20 is part of the Dymension series. The DM40 is also in this series. They share a design language. The CS models are separate. They are still black. Check the finish to avoid mismatched tones in your setup. All options here are consistent in color.
