Features and benefits in the MDW series of mini-diffusors are all the same as the MDF series, except all the diffusor units in this series are made of solid wood which is then stained and lacquered to furniture grade specifications. Each of the MDW series measures and weighs the same as the MDF series which puts them each at around 40 pounds. Check the photo gallery section for clear, oak, and walnut finishes. We can match any decor with a finish of your choice. The MDW series 11 is based on prime number 11. Consult us for finish, wood choice, and sizing options.
