“In our new studio we have tested (and measured) 7 different traps from leading European and American manufactures and got best results with SpringTrap from MSR Inc. Foam trap was absolutely ineffective below 100 Hz but as well as other traps affected the signal amplitude too much between 100 and 400Hz, thus sucking life out of music. The SpringTrap is the only product which helped us to get rid of bass issues, but kept our room sound live-like. Also it has the best build quality amongall competitors. We are happy to include SpringTrap to our portfolio.”
