How about furniture-grade speaker stands that are not only stylish, but can actually help improve your speakers' performance? Sanus' Basic Foundations® stands give you all that in an affordable package!

Basic Foundation stands are made with sturdy MDF (the same material used in many quality speaker cabinets) to resist unwanted resonance. Their twin contoured pillar design offers rock-steady support. Speaker wires run down a groove between the pillars — a snap-in black cover completely conceals the wires from sight, leaving just the clean lines of the stand. The stands come with triangular isolation pads for the top plate, to protect the speaker's finish, and provide additional resonance damping.

Hands-on research

Product Research


Overview: The BF31b speaker stands are constructed of MDF, which offers superior strength and resists unwanted resonance. The twin contoured pillars are aligned in a "V" configuration, offering additional rigidity and providing for the Speaker Cable Management System. A cover snaps into channels on the back of the pillars, hiding the cables from view. The supplied floor spikes further minimize resonance and provide stability on carpeting. The special triangular isolation pads are placed on the top plate for speaker protection and acoustic isolation.

Note: Each stand can support up to 20 pounds.


  • Overall: W=12.5", H = 29.875" (30.875" with spiked feet), D = 10.9375"
  • Top Plate: W = 5", D = 5"
  • Base Plate: W = 12.5", D = 10.9375"
