MartinLogan Motion Foundation C1

Center channel speakers often suffer from 'lobing,' where sound interference creates uneven audio depending on where you sit. The Motion Foundation C1 uses a specific crossover design to minimize this, ensuring dialogue remains clear and consistent even if you aren't sitting directly in the center sweet spot.

The C1 measures 7-5/8 inches high, 20 inches wide, and 10 inches deep. Before purchasing, measure your console's shelf height and depth to ensure it fits comfortably while leaving a little room for the rear port to breathe.

Yes, because this speaker is rear-ported, you should avoid pushing it flush against a wall. Leaving at least a few inches of clearance behind the speaker will prevent the bass from sounding muddy or boomy.

The C1 has an impedance of 4 ohms and a sensitivity of 91dB. While most modern home theater receivers can handle a 4-ohm load, check your receiver's manual to ensure it is rated for 4-ohm speakers to avoid overheating during high-volume playback.

Unlike traditional dome tweeters, this folded-film design moves air more efficiently with less mass. This results in high frequencies that sound exceptionally detailed and distortion-free, which is crucial for making movie dialogue and subtle sound effects crisp.

Yes, the speaker includes Secure-Lock Grilles that are easy to remove. This allows you to customize the look of your setup, whether you prefer the clean, covered aesthetic or the technical look of the aluminum mid-bass drivers.
