For detailed, realistic sound

These MartinLogan Motion Foundation B1 speakers feature an S Gen2 Obsidian Folded Motion tweeter, a Folded Motion waveguide and a 5.5" aluminium midrange driver. This design works perfectly to create a completely unexpected and engaging experience. These Foundation B1 speakers are ideal for small spaces, especially when combined with a subwoofer. They create a highly musical and detailed experience wherever high quality sound is desired. These Foundation B1 speakers are also threaded. This threading is perfect for positioning them on the STAND25 stand (sold separately), which provides a more stable mounting.
