The SQ 402 Speaker Support Stand Range are manufactured by the craftsman at Custom Design UK.
By combining the ERW BS EN 10305-3 steel support columns or the solid hardwood supports with 4mm Inert Acoustic Steel top plates and 4mm steel base plates, Custom Design has created a discrete. rigid speaker support stand. Mass loading the steel support columns with Inert Filler adds 7kg to the final mass, we recommend 1 bag of Inert Filler per column, improving the performance of your SQ 402 Speaker Stands.
