MartinLogan had three goals in mind when designing the STAND25. First, to create a more secure and stable solution to support B100, B10, B2, and B1 bookshelf speakers. For maximum stability, STAND25 is designed to thread into the bottom of the speaker using the hardware included with the speaker. Second, to maximize speaker performance, STAND25 can be filled with your choice of dampening material to minimize resonance. Additionally, both rubber feet and metal spikes are included for optimal performance on any floor surface. Lastly, for aesthetic appeal, STAND25 includes 3 interchangeable accent pieces to coordinate with the trim colors on the Motion XT, Motion, and Motion Foundation series speakers, while the integrated wire management channel allows you to conceal your speaker wire if desired.
