While Surplustronics will cease trading next month, owners Bruce Overhill and Gary Rollinson will focus on the opening of two mega-stores in Albany and Henderson, trading under the name of Sound Division.
Fisher said Sound Division would also focus on professional lighting and audio equipment.
"Sound Division is our pro lighting and sound sector, we used to do a lot of the small fiddly components but there's not much money in those anymore so we've moved on to more professional sound and lighting products for theatres and concerts," he said.
The company would like to thank its customers from its 30 years in business.
"Thanks for coming to our Queen St store over the years and we're excited to see you at our new branches," Fisher said.
