The SQ 404 Speaker Stand Range are a quadrifid design available with steel or solid hardwood support columns.


The SQ 404 design includes 4mm Inert Acoustic steel top and 5mm Inert Acoustic base plates combined with zinc plated M8 fixing bolts for total joint rigidity. The hand polished plates connect to ERW BS EN 10305-3 steel 50.8 x 50.8mm tubes, as standard for sound quality and as part of the Custom Design attention to detail philosophy.


The solid hardwood support columns are manufactured from solid Ash, Oak or Walnut. They are harvested from sustainable, professionally managed forests. Finishes available include White, Natural, Oak, Cherry, Mahogany, Walnut and Black. The natural properties of wood can dampen resonance noise vibration, preventing the transition through the design and influencing the stand and speakers performance, without the requirement for mass loading the support column.


We manufacture our world renowed Inert Acoustic Steel and Aluminium products for total isolation.


Custom Design is proud to present the award winning SQ 400 ranges. The SQ 404 Speaker Support Stand Range is manufacture by the craftsman at Custom Design.


By combining the ERW BS EN 10305-3 steel support columns or the solid hardwood supports with 4mm Inert Acoustic Steel top plates and 5mm Inert Acoustic steel base plates , Custom Design have created a discrete. totally rigid speaker support stand with significant initial Mass. Mass loading the steel support columns with Inert Filler, supplied as standard, adds greatly to the final mass, with 1 bag of Inert Filler recommended per column, maximising the performance of your SQ 404 Speaker support Stands.


Inert Acoustic Base plates are supplied as standard or the aesthetically pleasing 8mm Clear Glass base plinths manufactured to BS EN 12150-2.


The modern, contemporary SQ 404 ranges have true aesthetic appeal. When combined with Inert Acoustic Top and Base plates the reduction in resonance noise vibration is significant, resulting in an improved performance and sound quality.
