Know before you buy
Anti-lobing technology helps prevent the uneven sound distribution often found in traditional center channel speakers. It ensures that dialogue remains clear and consistent, even if you are sitting off to the side of the main listening position.
The Motion Foundation C1 is compatible with amplifiers rated for 4, 6, or 8 ohms. It performs best with an amplifier capable of delivering between 15 and 150 watts per channel.
This tweeter uses a thin, folded diaphragm to move air more efficiently than a traditional dome tweeter. This results in faster, more precise high-frequency response with significantly less distortion.
Measuring 7-5/8 inches high and 20 inches wide, the C1 is designed to be space-conscious. However, because it is a rear-ported speaker, you should ensure there is a few inches of clearance between the back of the cabinet and the wall to allow for proper airflow.
While it is voiced to match the rest of the MartinLogan Foundation series, it can be used with other brands. Keep in mind that for the most seamless soundstage, it is generally recommended to match the tweeter technology across your front three speakers.
Yes, it includes Secure-Lock grilles that are designed to stay firmly in place. They provide a clean, finished look while protecting the drivers from accidental contact.
