Primacoustic GO-TRAP Data Sheet

GOtRAP

The GoTrap™ is a 24” (610mm) x 36” (914mm) x 10” (254mm)
combination gobo and bass trap that is designed to meet the demands
of the professional stage or studio. The GoTrap features fabric covered
high-density glass wool panels on both sides for absorption of mid and

high frequencies. An internal berboard diaphragm provides a barrier to

block sound transmission between instruments while enhancing bass
absorption.

Made from multi-ply Baltic birch, the GoTrap is engineered with dove-tail
joints to provide years of service, and can be stacked to create isolation

walls. The GoTrap ships at, assembles in less than 15 minutes and is
available with a choice of three panel colors: black, beige and grey with a

natural birch frame.
