MartinLogan Motion Foundation B2

The waveguide helps control the dispersion of sound, ensuring a consistent audio experience across a wider listening area. It minimizes unwanted reflections from your walls, which helps maintain clarity even in rooms with challenging acoustics.

While they are designed as bookshelf speakers and can be placed on shelves, they perform best when placed on dedicated stands like the MartinLogan STAND25. Using stands helps isolate the speaker from vibrations and allows for better positioning to optimize the soundstage.

The B2s are quite efficient with a sensitivity of 89dB and are recommended for use with amplifiers between 15 and 100 watts. Most modern integrated amplifiers or receivers in this power range will drive them comfortably.

The 6.5-inch aluminum cone woofer provides a larger surface area, allowing the speaker to reach lower frequencies—down to 48Hz—with more authority. This results in a fuller, more robust sound that is better suited for larger rooms or primary listening setups.

Yes, the speakers feature Secure-Lock grilles that are easily removable. This allows you to customize the aesthetic of your setup depending on whether you prefer a sleek, covered look or the technical appearance of the drivers.

These crossovers are custom-tuned to ensure a seamless transition between the tweeter and the woofer. By precisely managing the frequency distribution, they help the speaker maintain a refined, balanced sound profile across the entire audio spectrum.
