Primacoustic MaxTrap Grey

Adding a single MaxTrap had a measurable effect on my bedroom studio acoustics as confirmed before/after by room measurement software - notably an overall reduction in decay above 400Hz but more importantly a significant reduction in individual room resonances from 350Hz down to around 60Hz. - just as I was hoping. A top quality product which also looks professional and not out of place in a domestic setting. I have since added a FullTrap and note further improvements.
